ベルトの駆動装置に関する。[Detailed Description of the Invention] The present invention relates to a toothed belt drive device consisting of a combination of a toothed belt and a pulley.
A belt with teeth in which two elliptical shapes intersect at the tips of the belt teeth is combined, and the belt and pulley are meshed together while maintaining the backlash between the pulley and the belt in a constant relationship to reduce the stress applied to the belt teeth. This invention relates to a drive device for a toothed belt, in which the stress is gradually reduced from the beginning to the end, thereby reducing the stress applied to the root of the belt tooth especially when the belt tooth disengages, thereby preventing the belt tooth root from cracking and achieving smooth disengagement. .

(Rubber Manufacturers Association) IP−24
(1978), there is a transmission system in which belt teeth with a trapezoidal cross section mesh with pulleys of similar shape. However, when this type of belt meshes with a pulley, the strain is concentrated at the base of the belt teeth, and the tips of the belt teeth do not become distorted even when fully engaged with the pulley, and most of the belt teeth are distorted. Unnecessary and essentially bearing little load. In addition, the load was unevenly transmitted from the belt teeth to the tensile member, and there was also the problem that interference occurred when the tips of the belt teeth engaged with the side surfaces of the pulley teeth.

いた。 Thus, the trapezoidal belt teeth cause such strain concentration, uneven transmission of load from the belt teeth to the tensile member, and tooth interference, so improvements have been desired.

の原因の１つである。 Therefore, as a device that improves the points mentioned above, the belt teeth intersect with each other and consist of two circular arcs each having the same radius. A combination of a toothed belt having the same contour and a pulley having an arcuate groove conduiting the teeth of the belt was provided. (U.S. Patent Claim No.
(See specification No. 3756091) However, one of the major drawbacks of this device is that it is designed to have a large backlash between the root of the belt teeth and the pulley, so when the belt starts driving, the movement distance of the belt or pulley is large. As a result, the belt groove surface is easily rubbed by the pulleys and worn out, and as a result, the tensile member is damaged.
This shortens the belt life. This phenomenon is particularly noticeable when the toothed belt is hung over a small pulley or when the belt is operated in reverse, but one of the reasons for this is that the belt groove surface is designed so that it comes into contact with the pulley tooth tip. .
そのため、これを改善する装置として例えば米

防止すると共にベルト溝部とプーリ歯部とのたた
き音を防止している。 Therefore, as a device to improve this, for example, as disclosed in U.S. Pat. No. 4,233,852, the height of the belt teeth is made larger than the depth of the pulley groove, thereby reducing the tip of the very limited belt teeth. By interfering with the bottom surface of the pulley groove, the belt groove is prevented from being rubbed by the surface of the teeth of the pulley, and the knocking noise between the belt groove and the pulley teeth is also prevented.
しかし、上記の装置の大きな欠点はベルト歯部

（抗張体と歯部を離そうとする力）は大きくな
り、歯元クラツクが生じやすくなる。 However, a major drawback of the above-mentioned devices is that tooth root cracks in the belt teeth occur over a short period of time. In other words, the backlash between the toothed belt and the pulleys is designed to be greatest at the root of the belt teeth or at the center of the belt teeth, and to be smaller at the tips of the belt teeth.Therefore, while the belt is driving, the belt teeth move from the center to the teeth. As it reaches the tip, it gradually receives larger compressive stress,
When the belt comes off the pulley, the pulley tooth tip rotates while gradually applying a larger force to the side surface of the belt tooth. As a result, the shearing force (force that tries to separate the tensile member from the tooth portion) applied to the belt root increases, making tooth root cracks more likely to occur.

せ体を提供することを目的とするものである。 The purpose of this invention is to deal with this situation and improve such points, and by increasing the backlash between the pulley and the belt linearly from the root of the belt tooth to the tooth tip, the relationship between the belt and the pulley is improved. The stress that the belt teeth receive during meshing is gradually reduced until it reaches the root of the belt teeth, and when the belt comes off the pulley, the pulley tooth tips are rotated while gradually applying a small force to the side surfaces of the belt teeth. It is an object of the present invention to provide a combination of a toothed belt and a pulley, which prevents early belt tooth base cracks by improving interference between the toothed belt and the pulley teeth.

加えたものであり、又r2はr1の約３倍である。 FIG. 1 is a cross-sectional view of the teeth of a pulley used in the toothed belt drive device of the present invention. In the figure, the pulley teeth 1 of pulley A are formed by an arc 2 with a radius of curvature r 1 . The pulley groove 5 between the teeth of the pulley is an arc with a radius of curvature r 2 and has a center point 7 on the center line 6 of the groove. 8, and the center point 7 of this groove is located at both ends 3 of the pulley teeth.
It is on the same line 10 as the center points 9, 9' of the arc 3'. Therefore, the height Hp of the pulley groove is the sum of r 1 and r 2 , and r 2 is approximately three times r 1 .

される。 On the other hand, the toothed belt B applied to the above pulley has teeth 13 at a constant pitch in the longitudinal direction of the belt.
and grooves 14 alternately, and the belt pitch line 1
A tensile rope material made of glass fiber, polyester fiber, aramid fiber, etc. is embedded in the top of the toothed belt 5, and the surfaces of the teeth 13 and grooves 14 are covered with a fabric. Part 13
is formed in accordance with the shape of the side wall of the pulley groove, as shown in FIG. That is, belt tooth portion 1
3 is a belt dentition root 17, 17' consisting of a circular arc 16 with a radius of curvature R 1 (however, R 1 < r 1 ) and a linear joint portion 18, 1 connected to the circular arc 16 of this belt dentition root.
8' and two elliptical arcs 20, 20' that intersect at the belt tooth tip 19, and the belt tooth portion 13 extends from the belt tooth root 17, 17' to the tooth tip 19 and meets the pulley groove side wall 8. The relationship is such that the gap increases linearly. In other words, when the toothed belt and the pulley are in static engagement, the backlash a between the belt teeth 13 and the pulley groove side wall 8 extends from the belt tooth root 17' to the tooth tip 19, as shown in the lower right of FIG. The main body of the belt tooth portion 13 is designed to increase linearly from side to side with the belt tooth center line 21 as an axis of symmetry. The slope .theta. of the backlash a is generally set in the range of 15" to 10.degree., preferably 1 to 4.degree..

〜20％小さくする。 Also, the angle θ B formed by the joint parts 18, 18' of the belt teeth is the angle θp of the joint parts 11, 11' of the pulley.
On the other hand, the radius of curvature R1 at the root of the belt tooth is approximately 0 from the radius of curvature R1 at the tip of the pulley tooth.
~20% smaller.

さくなるように分布する。 When a toothed belt that satisfies the above-mentioned backlash relationship is run on a pulley designed in advance in this way, the stress applied to the belt teeth 13 when the toothed belt comes off the pulley is reduced to the belt tooth tip 1.
9 to the belt tooth bases 17, 17', the distribution gradually decreases in size.

これは従来の駆動装置が見られたところである。 As a result, as shown in Fig. 4, when the belt comes off the pulley attached to the driven shaft, the side surface of the belt tooth portion 13 gradually moves away from the pulley while receiving a small force from the pulley tooth tip 3', thereby reducing the moment. From this relationship, the shearing force applied to the belt tooth bases 17, 17', that is, the force that tries to separate the tensile member from the belt tooth portion 13, does not increase, which has the effect of making tooth root cracks less likely to occur. Moreover, the belt comes off the pulley smoothly. However, as in the past, when the belt teeth are small at the root of the belt tooth and receive a large compressive stress from near the center of the belt tooth toward the tip, the shearing force applied to the root of the belt tooth gradually increases, and this is repeated. However, due to
This is where conventional drives were found.

It shows the state of being. S is the deformed portion of the belt.

ある。 As detailed above, the drive device of the present invention is a combination of a pulley having a generally known arc-shaped pulley groove side wall and a toothed belt having teeth in which two elliptical shapes intersect at the tips of the belt teeth. By increasing the backlash between the pulley and the belt linearly from the belt tooth root to the tooth tip, the stress applied to the belt tooth portion when the belt is driven is gradually reduced from the belt tooth root to the tooth tip. When the belt pulls out from the pulley, the stress applied to the belt tooth base is reduced, making belt tooth base cracks less likely to occur.
Furthermore, the durability of the belt is greatly improved by smoothly removing the belt from the pulley.
