Cage for inclined ball bearing
View Patent ↗A cage for inclined ball bearings with adjacent ball pockets separated from each other by webs. Elastically-deformable retainer lugs extend from the webs with flanks facing opposing directions and facing each other.
1. A cage for inclined ball bearings, comprising:
a side wall and a side rim spaced axially apart and interconnected by webs defining ball pockets,
the side wall having an approximately uniform wall thickness in an axial direction along an entire circumferential length of the sidewall with an arched portion of the side wall defining each of the ball pockets and being arched in the axial direction, and
the side rim having a uniform wall thickness in the axial direction along an entire circumferential length of the side rim; and
elastically resilient retaining lugs axially protruding at a linearly inclined angle from the webs that widen toward a unitary end and are circumferentially adjacent to each other, each of the retaining lugs being separated circumferentially from a further retaining lug by a gap,
wherein the retaining lugs have flanks, which extend linearly, pointing in opposite directions circumferentially and which are linearly inclined toward one another.
2. The cage as claimed in claim 1 , wherein each of the flanks has at least one straight body edge, the body edge being inclined by an angle with respect to an imaginary plane, the plane emanating from a rotational axis of the cage and being aligned with the rotational axis in the axial direction of the cage.
3. The cage as claimed in claim 2 , wherein each of the flanks is inclined with respect to a straight line which is imaginary and intersects the rotational axis.
4. The cage as claimed in claim 2 , wherein a circumferential spacing of two flanks which face away from one another on one of the retaining lugs increases with decreasing radial distance from the rotational axis.
5. The cage as claimed in claim 2 , wherein the flanks are flat faces, the faces being inclined at an acute angle with respect to one another.
6. The cage as claimed in claim 1 , wherein the retaining lugs protrude from face sections on the webs, the face sections facing a rotational axis of the cage.
7. The cage as claimed in claim 1 , wherein the retaining lugs protrude furthest in the axial direction at most as much as the side walls protrude the furthest in the axial direction, starting from the webs.
8. The cage as claimed in claim 1 , wherein a smallest radial spacing of the side rim from a rotational axis of the cage is greater than a greatest radial spacing of the side walls from the rotational axis.
