Abstract
A two-part ball bearing cage includes two, in particular at least substantially identical, cage parts forming an even-numbered plurality of ball pockets for receiving a corresponding number of balls having a predeterminable ball diameter. Each cage part has an annular body on which substantially evenly distributed webs are disposed in the circumferential direction to form the ball pockets. A distance in the circumferential direction between two webs that are adjacent in the circumferential direction approximately corresponds to the sum of twice the ball diameter and a width of the web in the circumferential direction. A ball bearing having the ball bearing cage and a method for assembly of the ball bearing are also provided.
Claims14
A two-part ball bearing cage, comprising:
- two cage parts forming an even-numbered plurality of ball pockets for respectively receiving a corresponding number of balls having a predefined ball diameter;
- each of said cage parts including a ring-shaped body having webs disposed thereon forming said ball pockets, said webs having a width and being distributed in a circumferential direction;
- each of said cage parts having a cylindrical inner circumferential surface in an axial direction and a conical surface in the axial direction, said conical surfaces each being located exclusively on an outer circumferential surface of a respective cage part;
- and
- each two of said webs disposed adjacent one another in said circumferential direction being spaced apart by a distance in said circumferential direction corresponding approximately to a sum of twice the predefined ball diameter and said width of one of said webs in said circumferential direction.
