Abstract

1481869 Bearings SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 12 Sept 1974 [19 Sept 1973] 39814/74 Heading F2A A bearing assembly comprising an inner ring 2 and an outer ring 3 rotatably mounted relative to each other by rolling elements 6, 7 arranged in two rows between the rings 2, 3, and a cage 10 separating the rolling elements 6, 7, being centred by them and being adapted to be inserted from one side only when they are in position, the bearing assembly being characterized in that the cage is so dimensioned as to permit relative movement in the circumferential direction of the bearing between each rolling element, e.g. 6, in one row and the adjacent rolling element 7 in the other row. The cage may be as Figs. 2 or 3 (not shown) where the balls in one row can move within a clearance gap (14) or (15), or as Fig. 4 (not shown), where the movement is permitted by flexing of the cage at narrow necks (22). The cage may be in two parts (25), (26), as in Figs. 5 and 6 (not shown); Fig. 6 shows the first part (26) being inserted. The ends (29A) and (29B) are provided with snap connections (30). The cage may be of polyamide or glass reinforced plastics.

付図面を参照して説明する。When the bearing is subjected to thrust or moment, if the conditions such as the contact angle of the balls in each row are different, the frictional force acting on the balls will differ depending on each row, so the circumferential speed of the balls will change depending on the load. Within the area, each row is slightly different. The bearing cage, which holds the balls in each row of the double row mentioned above together without any gaps, is rigid and does not have any means to accommodate this, so in that case, excessive stress may be generated in the cage or the cage may generate squeaks. , an undesirable situation occurs. Furthermore, if a gap is maintained between the balls in both rows to avoid this, the cage will wobble in the radial direction, causing vibration in centering. Therefore, in the present invention, the cage is made of plastic and has two legs 17 and 18 parallel to each other in all directions of the axis, and a closing part 19 that connects one end of both legs. Each distribution section 16 consists of a large number of distribution sections 16 that house two balls 6 and 7 adjacent to each other in the axial direction of the sphere section, and a connecting section 22 that connects the legs of the distribution sections in the circumferential direction. is deformable in the circumferential direction using the connecting portion 22 as a hinge, and each of the leg portions 17,
18 cooperates with the closing part 19 to have the balls of one row of balls in the direction of the ball, and has snap claws 12, 12 at the free end for movably holding the other row of balls in the direction of the ball. The bearing is centered by the balls of one row of balls held by the protrusions 20, 21 and the balls of the other row of balls held by the snap claws 12, 12, and as described above, the bearing generates thrust or moment. When the circumferential speeds of the balls in each row differ slightly within the load range, the distribution part 16 deforms in the circumferential direction using the connecting part 22 as a hinge, thereby absorbing the speed difference in the load range. This allowed the balls in both rows to revolve at different speeds. The present invention will now be described with reference to the accompanying drawings.

If the circumferential speeds of the balls 6 and 7 in each row 1 and B differ slightly in the load range, the distribution part 16 in the load castle is
2 is used as a hinge to deform in the circumferential direction and respond flexibly.
This flexibility of the distribution part is also due to the fact that the distribution part itself is deformable, ensuring an optimum state under any load conditions. That is, the spheres can also move to some extent in the circumferential direction by deforming the distribution part, so that the spheres in both rows revolve at different speeds and absorb the speed difference. To improve the snap fit of the balls 6, 7 into the distribution part 16, the bases of the legs 17, 18 surrounding the ball 7 and the end face 23 of the closure part 19 are
Surfaces 24 are provided at the corners of the cage, and when inserting the cage into the bearing, it is preferable to iron a mounting tool onto these surfaces 23 and 24. This embodiment, in which the triangular protrusions 20, 21 and the closure 19 surround half or three quarters of the sphere 7, has the advantage of operational safety. The invention is not limited to the illustrated embodiment.
