Abstract

The DC60 described is a roller bearing (1) for a locking rod. Such a roller bearing consists of at least some circular outer sections (2), at least some circular inner sections (3), and numerous rollers (5) which are assembled between the outer sections (2) and the inner sections (3). The roller bearing is characterized by the fact that at least one roller (5) is composed of two opposing curved side faces (6,7) which, when viewed in cross-section, at least one forms the arc length of the same imaginary circle (10), and which forms the contact surfaces for the outer and inner circular sections (2,3), respectively, and at least one side face (8,9) which lies within the aforementioned imaginary circle (10). Thus, it is possible to obtain a number of rollers in the bearing, thus reducing the load on each roller to the same rate of overall load, thus increasing the overall load capacity of the bearing. This is due to the fact that at least some of the surfaces of the rollers of a conventional circular roller bearing are oriented in a certain way. The rollers that do not come into contact with the outer or inner parts of the bearing due to their low reactive angular rotation are omitted, thus significantly reducing the space occupied by the roller elements in the circumferential direction of the bearing. This is described as a roller bearing (1) for a tongue and groove roller bearing. Such a roller bearing consists of at least some partially circular outer parts (2), at least some partially circular inner parts (3), and numerous roller elements (5) which are assembled between the outer (2) and inner (3) parts. The roller bearing is characterized by the fact that at least one of the roller elements (5) is incorporated by two opposing curved side faces (6,7) which, when viewed in cross-section, at least one side They form arc lengths of the same imaginary circle (10), and which form the contact surfaces for the outer and inner circles (2,3), respectively, and at least one bevel surface (8,9) which lies within the aforementioned imaginary circle (10). Thus, it is possible to obtain an increase in the number of roller elements in a bearing, thus reducing the load on each individual roller element under the same rate of overall load, thus increasing the overall load capacity of the bearing. This is due to the fact that at least some of the roller surfaces of the original circular rollers, which do not come into contact with the outer or inner zones of the bearing due to minimal angular response, are omitted, thus significantly reducing the space occupied by the roller elements in the circumferential direction of the bearing.

Claims (9)

1. Roller bearing (1) for rocker arm, such roller bearing consists of at least some partial circular outer sections (2), at least some partial circular inner sections (3), and numerous rollers (5) which are assembled between the outer sections (2) and the inner sections (3), with the characteristic that at least one of the rollers (5) consists of two opposing curved side faces (6,7) which, when viewed in at least one cross-section, form the arc length of the same imaginary circle (10) and which form the contact surfaces for the outer and inner circular sections (2,3), respectively, and at least one side face (8,9) which lies within the aforementioned imaginary circle (10). 2. The roller bearing under claim 1 is characterized by the side surfaces (8,9) of the roller element (5) enclosed within an imaginary circle (10) being planar and each side forming chords (11, 12) within an imaginary cross-sectional circle (10). 3. The roller bearing under claim 2 is characterized by its side surface (5) being composed of two opposing side surfaces (8, 9) which, when viewed in cross-section, each form a cord (11, 12) in an imaginary circle (10). 4. The roller bearings under claim 2 are characterized by the chords (11, 12) forming smaller angles between each other, so the width of the roller segment (5) is greatest relative to the outer circle (2). 5. The roller bearings under claim 2 are characterized in that they consist of an angular segment (15) which is arranged between two circular segments (2,3) in place of some roller segments (5). 6. The roller bearing under claim 2 is characterized by the angular element (15) being made such that it protrudes over an area of approximately 90% of the circumference and by radial overhangs, thus an angular clearance is present between the angular element (15) and one of the central circles (2, 3). 7. The roller bearings under claim 2 are characterized by the angular parts (15) being provided with beveled end faces (16, 17) to ensure the required contact with the adjacent roller parts (5) when the bearing in its furthest position is subjected to the required maximum angular rotation and thus to produce a self-locking effect. 8. The roller bearings under claim 2 are characterized by the fact that the roller bearings are assembled with rollers which maintain the position of the rollers (5) relative to each other in the circumferential direction. 9. The use of roller bearings under any of the claims 1 through 8 in a roller crusher (21) for crushing particulate materials such as cement raw materials, cement clinger and similar materials, where such roller crusher (21) consists of a platform for significant horizontal response (23) and a roller assembly capable of rotating around a vertical shaft (25), such roller assembly consists of a number of rollers (24) rotating around a specific roller shaft (26) which is connected to the vertical shaft (25) via a hinged connection (27) allowing free circular movement of the rollers up and down in a plane comprising the centerline (22) of the roller shaft, and such roller assembly is made conduit for reactive operation with the crushing platform, to which roller bearings (1) are incorporated as part of the hinged connection (27).
