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.

の一実施例の一部を示す。When the bridge is subjected to thrust or moment, if 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. varies slightly for each row within the load range. The bearing cage that holds the balls in each row of the grain rows mentioned above together without any gaps is
Since it is rigid and does not have a corresponding means, in that case excessive stress is created on the cage, it produces 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 integral plastic, has an annular part centered on the axis, and protrudes in the axial direction from the annular part while maintaining a constant interval in the circumferential direction that is larger than the diameter of the balls in both ball rows. It has a large number of partition pieces that separate circumferentially adjacent balls of both balls, and each of the partition pieces holds the balls of one row of balls without gaps in the base weave part or free bridge part connected to the annular part. It is characterized by having snap claws facing each other, and the balls of one row of balls are held and centered by the snap claws without any gaps, and the balls of the other row of balls are held between adjacent partition pieces. This made the ball movable in the circumferential direction, thereby absorbing the speed difference in the load range and allowing the balls in both ball rows to revolve at different speeds.
The present invention will now be described with reference to the accompanying drawings. FIG. 1 shows a bearing to which the ball cage of the present invention can be applied. The bearing 1 has an inner ring 2 integrally provided with a flange 4, an outer ring 3 integrally provided with a flange 5, and a flange 4. and 5 can be fixed to, for example, a wheel hub or a brake mechanism of an automobile. The bearing 1 has two ball rows 1 and 0 consisting of balls 6... and 7 that roll along raceway surfaces 8 and 9 and 8A and 9A of the inner ring and outer ring, and both ball rows The balls 6... and 7...● are separated from each other in the circumferential direction by a cage 10. Balls 6... and 7...
・In order to fit between the inner and outer wheels, one bearing ring is eccentric to the other to form a crescent-shaped space between the two wheels.
Fill a predetermined number of balls from this space, center both wheels, arrange the balls in two rows in the orbital plane, and then place the balls in the cage 10.
Insert the inner ring between the inner and outer rings in the axial direction from the end face side that does not have the inner ring. FIG. 2 shows a portion of one embodiment of a cage according to the invention molded from amide, acetate, or similar stable synthetic resin.

する。The cage has an annular part 13, from which partition pieces 11 protrude in the rut direction at intervals in the circumferential direction, and two snap claws 12 are provided at the base end of each partition piece, facing each other. ,
The snap claw 12 holds the ball 7 of the ball row 0, and the ball 7 is attached to the annular part 1.
It is in contact with 3. Since the interval in the circumferential direction between the partition pieces 11 is larger than the diameter of the sphere, there is a gap 14 between the partition pieces 11 and 11 of the balls 6 in the ball row 1, and this gap 14 allows the balls 6 to revolve differently from the spheres 7. It can rotate at high speed, the bearing is thrust,
absorbs the speed difference in the load region when a moment is applied.

なっていて、第２図のケージと同様な効果を奏する。Furthermore, centering of the cage is performed by the balls 7 of ball row 0 held tightly by snap claws 12. In the cage of the embodiment shown in FIG. 3, the balls 6 of ball row 1 are held by the snap claws 12 at the free ends of the partition pieces 11, and the balls 7 of ball row 0 are held by the partition pieces 11,
It is movable in a space 15 that is larger than the direct diameter of the sphere at the back of the space 11, and has the same effect as the cage shown in FIG.
