Moreover, according to the embodiment of the present invention, it is possible to increase the load resistance of a wheel equipped with a roller.

以下，參照圖式對本發明之實施形態進行說明。首先，參照圖1a～圖1c及圖2對本發明之一實施形態進行說明。圖1a～圖1c概略地表示本發明之一實施形態之輪具1。圖2模式性表示輪具1所具備之滾筒之剖面。Hereinafter, an embodiment of the present invention will be described with reference to the drawings. First, an embodiment of the present invention will be described with reference to FIGS. 1a to 1c and 2. 1a to 1c schematically show a wheel 1 according to an embodiment of the present invention. FIG. 2 schematically shows a cross section of the roller provided in the wheel 1.

該等圖中所示之輪具1具備：輪具體2，其具有一對支持構件3；及複數個滾筒5，其等配置於該一對支持構件3之間。一對支持構件3具有大致碟狀之形狀。於一對支持構件3之各者之外周面9設置有複數個凹部10。The wheel 1 shown in these figures includes: a wheel body 2 having a pair of support members 3; and a plurality of rollers 5, which are arranged between the pair of support members 3. The pair of support members 3 has a substantially dish-like shape. Plural recesses 10 are provided on the outer peripheral surface 9 of each of the pair of support members 3.

滾筒5具有沿著旋轉軸15延伸之滾筒軸5c。滾筒軸5c係其兩端部分固定於一對支持構件3之外周面9之凹部10。滾筒5可繞滾筒軸5c旋轉地被一對支持構件3支持。因此，滾筒5可繞圖1c所示之旋轉軸15旋轉。一對支持構件3係藉由未圖示之驅動裝置而被驅動。一對支持構件3相互固定。輪具體2可繞旋轉軸12向兩個方向旋轉。The drum 5 has a drum shaft 5c extending along the rotating shaft 15. The roller shaft 5c is fixed to the concave portion 10 of the outer peripheral surface 9 of the pair of support members 3 at both ends thereof. The drum 5 is rotatably supported by a pair of support members 3 around the drum shaft 5c. Therefore, the drum 5 can rotate around the rotation shaft 15 shown in FIG. 1c. The pair of support members 3 is driven by a driving device (not shown). The pair of support members 3 are fixed to each other. The wheel body 2 can rotate in two directions around the rotation axis 12.

複數個滾筒5係於一對支持構件3之間彼此空開均等間隔地配置。圖示之輪具1具有8個滾筒5。輪具1具備之滾筒5之數量並不限於8個，可適當地變更。圖示之實施形態中，滾筒5具有中高之(crowned or barrel-shaped)外側輪廓。滾筒5之旋轉軸15相對於輪具體2之旋轉軸12形成角度α。角度α例如為45°。角度α並不限於45°，可適當地變更。The plurality of rollers 5 are arranged between the pair of support members 3 at equal intervals from each other. The illustrated wheel 1 has eight rollers 5. The number of rollers 5 included in the wheel 1 is not limited to 8, and can be changed as appropriate. In the illustrated embodiment, the drum 5 has a crowned or barrel-shaped outer contour. The rotation axis 15 of the drum 5 forms an angle α with respect to the rotation axis 12 of the wheel body 2. The angle α is, for example, 45°. The angle α is not limited to 45°, and can be changed as appropriate.

如圖1b所示，滾筒5係以其一部分較一對支持構件3之外周更向徑向外側略微突出之方式安裝於支持構件3。滾筒5係以較該支持構件3之外周更向徑向外側突出之部位接觸地面或地板。As shown in FIG. 1b, the drum 5 is attached to the support member 3 in such a manner that a part thereof protrudes slightly radially outward from the outer periphery of the pair of support members 3. The drum 5 contacts the ground or the floor with a portion protruding radially outward from the outer periphery of the support member 3.

一實施形態中，輪具1之外徑與最大之滾筒半徑之比為1.107。藉此，可無關於輪具1之外徑而獲得輪具1之最佳的輥行為。In one embodiment, the ratio of the outer diameter of the wheel 1 to the largest drum radius is 1.107. Thereby, the best roll behavior of the wheel 1 can be obtained regardless of the outer diameter of the wheel 1.

本發明之一實施形態中，輪具體2之重量設為輪具1全體之重量之80%。輪具體2之重量為輪具1全體之重量之80%，除了包含輪具體2之重量嚴格地為輪具1全體之重量之80%的情況以外，還包含輪具體2之重量大約為輪具1全體之重量之80%的情況。例如，於輪具體2之重量為輪具1全體之重量之75%～85%之範圍、76%～84%之範圍、77%～83%之範圍、78%～82%之範圍、或79%～81%之範圍之情形時，亦可稱為輪具體2之重量為輪具1全體之重量之約80%。藉由將輪具體2之重量設為輪具1全體之重量之80%，可減小一對支持構件3被驅動時之輪具1之速度變化，其結果，可減小作用於滾筒5之負荷之變化。如此，不會對滾筒5臨時施加較大負荷，從而抑制滾筒5之破損。藉此，可使滾筒5及具備該滾筒5之輪具1實現高耐負荷化。In one embodiment of the present invention, the weight of the wheel 2 is 80% of the weight of the wheel 1 as a whole. The weight of the wheel 2 is 80% of the total weight of the wheel 1 except that the weight of the wheel 2 is strictly 80% of the weight of the wheel 1 and the weight of the wheel 2 is approximately the wheel 1 80% of the total weight. For example, the weight of the wheel 2 is in the range of 75% to 85%, 76% to 84%, 77% to 83%, 78% to 82%, or 79 of the total weight of the wheel 1 In the range of% to 81%, the weight of the wheel 2 can also be called about 80% of the weight of the wheel 1 overall. By setting the weight of the wheel 2 to 80% of the total weight of the wheel 1, the speed change of the wheel 1 when the pair of support members 3 are driven can be reduced, and as a result, the effect on the drum 5 can be reduced Change in load. In this way, a large load is not temporarily applied to the drum 5, and the damage of the drum 5 is suppressed. As a result, the drum 5 and the wheel 1 equipped with the drum 5 can achieve high load resistance.

其次，參照圖2，進一步說明滾筒5。圖2係模式性表示滾筒5之沿著旋轉軸15之剖面。如圖所示，滾筒5具有滾筒構件5a、滾筒芯5b、滾筒軸5c。滾筒構件5a具有中高之外側輪廓。滾筒構件5a具有沿著旋轉軸15而自一端延伸至另一端之貫通孔，於該貫通孔設置有滾筒芯5b。滾筒5b之外周面係與旋轉軸15平行地延伸。滾筒芯5b亦具有沿著旋轉軸15而自一端延伸至另一端之貫通孔，於該貫通孔插入滾筒軸5c。滾筒軸5c係沿著旋轉軸15而自一端5c1延伸至另一端5c2之棒狀之構件。Next, referring to FIG. 2, the drum 5 will be further described. FIG. 2 schematically shows a section of the drum 5 along the rotation axis 15. As shown in the figure, the drum 5 has a drum member 5a, a drum core 5b, and a drum shaft 5c. The roller member 5a has a middle-high outer profile. The roller member 5a has a through-hole extending from one end to the other end along the rotating shaft 15, and a roller core 5b is provided in the through-hole. The outer peripheral surface of the drum 5b extends parallel to the rotating shaft 15. The drum core 5b also has a through hole extending from one end to the other end along the rotating shaft 15, and the drum shaft 5c is inserted into the through hole. The drum shaft 5c is a rod-shaped member extending from one end 5c1 to the other end 5c2 along the rotating shaft 15.

滾筒構件5a例如由聚氨酯彈性體等樹脂材料形成。滾筒構件5a亦可由樹脂材料以外之具有可撓性之材料形成。滾筒芯5b及滾筒軸5c係由金屬材料形成。滾筒芯5b及滾筒軸5c經淬火處理。如此，藉由對滾筒芯5b及滾筒軸5c進行淬火處理，可提高滾筒芯5b及滾筒軸5c之強度。因此，可減小滾筒芯5b及滾筒軸5c之直徑。又，藉由減小滾筒芯5b及滾筒軸5c之直徑，可減小滾筒構件5a之厚度。藉此，可使滾筒5及具備該滾筒5之輪具1實現高耐負荷化。The roller member 5a is formed of a resin material such as polyurethane elastomer, for example. The roller member 5a may be formed of a material having flexibility other than the resin material. The roller core 5b and the roller shaft 5c are formed of a metal material. The drum core 5b and the drum shaft 5c are quenched. In this way, by quenching the drum core 5b and the drum shaft 5c, the strength of the drum core 5b and the drum shaft 5c can be improved. Therefore, the diameter of the drum core 5b and the drum shaft 5c can be reduced. Furthermore, by reducing the diameters of the drum core 5b and the drum shaft 5c, the thickness of the drum member 5a can be reduced. As a result, the drum 5 and the wheel 1 equipped with the drum 5 can achieve high load resistance.

若對滾筒芯5b進行淬火處理，則有滾筒芯5b產生變形之可能性。本發明之一實施形態中，滾筒芯5b亦可於淬火處理後對其外表面進行研磨。如此，藉由對滾筒芯5b之外表面進行研磨處理，可抑制因滾筒芯5b變形導致負荷偏向滾筒構件5a之內周面之狀況。藉此，可抑制滾筒構件5a之破損。藉此，可使滾筒5及具備該滾筒5之輪具1實現高耐負荷化。If the drum core 5b is quenched, the drum core 5b may be deformed. In one embodiment of the present invention, the drum core 5b may also be polished on the outer surface after quenching. In this way, by grinding the outer surface of the drum core 5b, it is possible to suppress a situation where the load is biased toward the inner circumferential surface of the drum member 5a due to deformation of the drum core 5b. Thereby, damage to the roller member 5a can be suppressed. As a result, the drum 5 and the wheel 1 equipped with the drum 5 can achieve high load resistance.

如圖2所示，滾筒芯5b係經由2個軸承6及2個軸承13而安裝於滾筒軸5c。2個軸承6亦可設置於相對於滾筒軸5c之旋轉軸方向之中心C而相互對稱的位置。滾筒軸5c之旋轉軸方向之中心C係一端5c1與另一端5c2之間之中點。2個軸承13亦可設置於相對於滾筒軸5c之旋轉軸方向之中心C而相互對稱的位置。圖示之實施形態中，軸承6為推力軸承，軸承13為徑向軸承。軸承6及軸承13之至少一者亦可為斜角軸承、錐形軸承、或該等以外之周知軸承。沿著旋轉軸15之軸向(以下有時僅稱為「旋轉軸方向」)，滾筒芯5b之相對於滾筒軸5c之位置係藉由軸承6規定。As shown in FIG. 2, the drum core 5b is attached to the drum shaft 5c via two bearings 6 and two bearings 13. The two bearings 6 may be provided at positions symmetrical to each other with respect to the center C of the rotation axis direction of the drum shaft 5c. The center C of the rotation axis direction of the drum shaft 5c is the midpoint between one end 5c1 and the other end 5c2. The two bearings 13 may be provided at positions symmetrical to each other with respect to the center C of the rotation axis direction of the drum shaft 5c. In the illustrated embodiment, the bearing 6 is a thrust bearing, and the bearing 13 is a radial bearing. At least one of the bearing 6 and the bearing 13 may also be a bevel bearing, a tapered bearing, or a well-known bearing other than these. The position of the drum core 5b relative to the drum shaft 5c along the axial direction of the rotating shaft 15 (hereinafter sometimes simply referred to as "rotating shaft direction") is defined by the bearing 6.

滾筒芯5b具有自旋轉軸方向之D1方向之端向滾筒軸5c之中心C凹陷之凹部5b1，且具有自旋轉軸方向之D2方向之端向滾筒軸5c之中心C凹陷之凹部5b2。2個軸承6之各者收容於該凹部5b1及凹部5b2。軸承6具有第1軌道輪6a、第2軌道輪6b、及配置於該第1軌道輪6a與第2軌道輪6b之間之複數個滾動體6c。第1軌道輪6a係安裝於滾筒軸5c，第2軌道輪6b係安裝於滾筒芯5b。第1軌道輪6a亦可與滾筒軸5c一體構成。即，第1軌道輪6a與滾筒軸5c亦可為一體之整體構件。亦可對第1軌道輪6a實施淬火處理。第2軌道輪6b亦可與滾筒芯5b一體構成。即，第2軌道輪6b與滾筒芯5b亦可為一體之整體構件。亦可對第2軌道輪6b實施淬火處理。The drum core 5b has recesses 5b1 recessed toward the center C of the drum shaft 5c from the end in the D1 direction of the rotation axis direction, and has recesses 5b2 recessed toward the center C of the drum shaft 5c from the end in the D2 direction of the rotation axis direction. Each of the bearings 6 is accommodated in the recess 5b1 and the recess 5b2. The bearing 6 includes a first track wheel 6a, a second track wheel 6b, and a plurality of rolling elements 6c disposed between the first track wheel 6a and the second track wheel 6b. The first rail wheel 6a is attached to the drum shaft 5c, and the second rail wheel 6b is attached to the drum core 5b. The first rail wheel 6a may be formed integrally with the drum shaft 5c. That is, the first rail wheel 6a and the drum shaft 5c may be an integrated integral member. The first rail wheel 6a may be quenched. The second rail wheel 6b may be formed integrally with the drum core 5b. That is, the second rail wheel 6b and the drum core 5b may be an integrated integral member. The second rail wheel 6b may be quenched.

滾筒軸5c具有於其周向延伸之2個槽，於該2個槽之各者設置有規制構件。於圖示之實施形態中，使用止動輪7作為規制構件。止動輪7嵌入於槽。因此，止動輪7之向旋轉軸方向之移動被規制。於止動輪7與筒狀構件5b之間設置有間隔件14。於圖示之實施形態中，間隔件14設置於止動輪7與軸承6之間。止動輪7具有穿過其中心之貫通孔，於該貫通孔插入滾筒軸5c。同樣地，間隔件14具有環狀之形狀。間隔件14具有穿過其中心之貫通孔，於該貫通孔插入滾筒軸5c。於間隔件14與止動輪7之間亦可設置未圖示之填隙片。填隙片亦可設置於間隔件14與軸承6之間。亦可將旋轉軸方向上之間隔件14之位置與止動輪7之位置調換。換言之，亦可不設置。例如，間隔件14亦可設置於軸承6與筒狀構件5b之間。亦可使用螺釘作為規制構件。The drum shaft 5c has two grooves extending in the circumferential direction, and a regulation member is provided in each of the two grooves. In the illustrated embodiment, the stop wheel 7 is used as the regulatory member. The stop wheel 7 is fitted into the groove. Therefore, the movement of the stop wheel 7 in the direction of the rotation axis is regulated. A spacer 14 is provided between the stop wheel 7 and the cylindrical member 5b. In the illustrated embodiment, the spacer 14 is provided between the stop wheel 7 and the bearing 6. The stop wheel 7 has a through hole passing through its center, and the drum shaft 5c is inserted into the through hole. Similarly, the spacer 14 has a ring shape. The spacer 14 has a through hole passing through the center thereof, and the roller shaft 5c is inserted into the through hole. A shim (not shown) may also be provided between the spacer 14 and the stop wheel 7. The shim can also be provided between the spacer 14 and the bearing 6. The position of the spacer 14 in the rotation axis direction and the position of the stop wheel 7 can also be exchanged. In other words, it may not be set. For example, the spacer 14 may be provided between the bearing 6 and the cylindrical member 5b. Screws can also be used as regulatory components.

於滾筒軸5c之兩端設置有於與旋轉軸15正交之方向延伸之孔16。於孔16插入螺栓8。於支持構件3之凹部10設置有承接螺栓8之螺孔。滾筒軸5c係藉由將螺栓8螺入凹部10之螺孔而固定於支持構件3。如此，滾筒軸5c藉由螺栓8而安裝於支持構件3。一實施形態中，孔16之內徑大於螺栓8之軸部之外徑。因此，螺栓8之軸部與孔16之內周面之間存在間隙。由此，可藉由該間隙之間隔而調整滾筒軸5c相對於支持構件3之安裝位置。滾筒軸5c亦可藉由螺栓8緊固以外之周知手法固定於凹部10。At both ends of the drum shaft 5c, holes 16 extending in a direction orthogonal to the rotation shaft 15 are provided. Insert bolt 8 into hole 16. The recess 10 of the supporting member 3 is provided with a screw hole for receiving the bolt 8. The drum shaft 5c is fixed to the support member 3 by screwing the bolt 8 into the screw hole of the recess 10. In this way, the roller shaft 5c is attached to the support member 3 with the bolt 8. In one embodiment, the inner diameter of the hole 16 is larger than the outer diameter of the shaft portion of the bolt 8. Therefore, there is a gap between the shaft portion of the bolt 8 and the inner circumferential surface of the hole 16. Thereby, the installation position of the roller shaft 5c with respect to the support member 3 can be adjusted by the interval of this gap. The drum shaft 5c can also be fixed to the recess 10 by a well-known technique other than tightening with the bolt 8.

其次，參照圖3對本發明之其他實施形態之輪具之滾筒進行說明。圖3所示之滾筒105與圖2所示之滾筒5之不同點在於，具備滾筒構件105a代替滾筒構件5a，且具備滾筒芯105b代替滾筒芯5b。對圖3所示之滾筒105之構成要素中之與圖1所示之滾筒5之構成要素相同或相似者附加與圖1相同或相似之參照符號，且省略該等相同或相似之構成要素之詳細說明。Next, referring to Fig. 3, a roller of a wheel according to another embodiment of the present invention will be described. The roller 105 shown in FIG. 3 is different from the roller 5 shown in FIG. 2 in that a roller member 105a is provided instead of the roller member 5a, and a roller core 105b is provided instead of the roller core 5b. Of the constituent elements of the drum 105 shown in FIG. 3, those that are the same as or similar to the constituent elements of the drum 5 shown in FIG. 1 are attached with the same or similar reference signs as in FIG. 1, and the same or similar constituent elements are omitted. Detailed description.

滾筒芯105b形成為桶狀之形狀。即，滾筒芯105b其外表面具有中高之(crowned or barrel-shaped)形狀。換言之，滾筒芯105b係於滾筒軸5c之旋轉軸方向之中心C附近向徑向外側鼓起。由此，滾筒芯105b構成為於滾筒軸5c之旋轉軸方向之中心C附近之厚度較旋轉軸方向之端部附近厚。The drum core 105b is formed in a barrel shape. That is, the outer surface of the drum core 105b has a crowned or barrel-shaped shape. In other words, the drum core 105b is bulged radially outward near the center C of the drum shaft 5c in the rotation axis direction. Thus, the drum core 105b is configured to have a thicker thickness near the center C of the drum shaft 5c in the rotation axis direction than near the end portion in the rotation axis direction.

滾筒構件105a以覆蓋滾筒芯105b之外表面之方式設置。滾筒構件105a亦可以大致均等之厚度設置於滾筒芯105b之外表面。由於滾筒芯105b具有桶狀之形狀，因此滾筒構件105a於滾筒軸5c之旋轉軸方向之中心C附近向徑向外側鼓起。The roller member 105a is provided so as to cover the outer surface of the roller core 105b. The drum member 105a may be provided on the outer surface of the drum core 105b with a substantially uniform thickness. Since the drum core 105b has a barrel shape, the drum member 105a bulges radially outward in the vicinity of the center C in the rotation axis direction of the drum shaft 5c.

其次，參照圖4，對本發明之其他實施形態之輪具之滾筒進行說明。圖4所示之滾筒205與圖3所示之滾筒105之不同點在於，具備滾筒構件205a代替滾筒構件105a。對圖4所示之滾筒205之構成要素中之與圖3所示之滾筒105之構成要素相同或相似者附加與圖1相同或相似之參照符號，且省略該等相同或相似之構成要素之詳細說明。Next, referring to Fig. 4, a roller of a wheel according to another embodiment of the present invention will be described. The roller 205 shown in FIG. 4 is different from the roller 105 shown in FIG. 3 in that a roller member 205a is provided instead of the roller member 105a. Among the constituent elements of the drum 205 shown in FIG. 4, those that are the same as or similar to the constituent elements of the drum 105 shown in FIG. 3 are attached with the same or similar reference signs as in FIG. 1, and the same or similar constituent elements are omitted. Detailed description.

自滾筒軸5c之軸向觀察，滾筒構件205a之厚度形成為滾筒構件18之端部區域較中央區域厚。滾筒構件18之中央區域之厚度亦可為滾筒軸5c之旋轉軸方向上中心C之位置的滾筒構件18之厚度t1。滾筒構件18之端部區域之厚度亦可為滾筒軸5c之旋轉軸方向上滾筒軸5c之一端5c1、與2個軸承6中鄰接於一端5c1之軸承6之滾動體6c之間的區域之厚度t2。滾筒構件205a構成為於滾筒軸5c之旋轉軸方向上，滾筒軸5c之旋轉軸方向之中心C附近之厚度t1小於端部附近之厚度t2。Viewed from the axial direction of the drum shaft 5c, the thickness of the drum member 205a is formed such that the end region of the drum member 18 is thicker than the center region. The thickness of the central region of the drum member 18 may also be the thickness t1 of the drum member 18 at the position of the center C in the rotation axis direction of the drum shaft 5c. The thickness of the end region of the roller member 18 may also be the thickness of the region between the one end 5c1 of the roller shaft 5c in the direction of the rotation axis of the roller shaft 5c and the rolling element 6c of the bearing 6 adjacent to the one end 5c1 of the two bearings 6 t2. The drum member 205a is configured so that the thickness t1 near the center C of the drum shaft 5c in the rotation axis direction is smaller than the thickness t2 near the ends in the drum axis 5c rotation axis direction.

滾筒構件205a構成為其端部區域之厚度較中央區域之厚度厚，因此相比具有均勻厚度之滾筒構件，可減小中央區域之壓縮量與端部區域之壓縮量之差。藉此，應力不會集中於滾筒構件205a之一部分，因此可使滾筒構件205a及具備該滾筒構件205a之輪具1實現高耐負荷化。The roller member 205a is configured such that the thickness of the end region is thicker than the thickness of the central region. Therefore, compared with a roller member having a uniform thickness, the difference between the compression amount in the central region and the compression amount in the end region can be reduced. Thereby, stress does not concentrate on a part of the roller member 205a, and therefore the roller member 205a and the wheel 1 provided with the roller member 205a can be made to withstand high loads.

本說明書中說明之各構成要素之尺寸、材料及配置並不限定於實施形態中明確說明者，該各構成要素可變形為具有本發明之範圍可包含之任意尺寸、材料及配置。又，可將本說明書中未明確說明之構成要素附加於已說明之實施形態，亦可省略各實施形態中說明之構成要素之一部分。與上述各種實施形態中之一者關聯而說明之特徵亦可應用於其他實施形態。The size, material, and arrangement of each component described in this specification are not limited to those explicitly described in the embodiments, and each component can be modified to have any size, material, and arrangement that can be included in the scope of the present invention. In addition, constituent elements not explicitly described in this specification may be added to the described embodiments, or a part of the constituent elements described in each embodiment may be omitted. The features described in relation to one of the various embodiments described above can also be applied to other embodiments.
