ABSTRACT:
An improved single-row multi-point-contact ball bearing for an electromagnetic clutch and pulley and for a compressor for an automobile air conditioner is provided, which has a low relative inclination between the inner and outer rings and rotatable at a high revolution of about 10,000 rpm, and yet inexpensive requiring a small axial space.
A single-row four-point contact angular ball bearing is provided which comprises an one-piece inner and outer rings. Each raceway surface of the inner and outer rings is made to form a Gothic-arched configuration having two curved surfaces, and each radius of curvature of the two curved surfaces is made to range substantially 0.515 to 0.55 of the outer diameter of a ball. Further, a single-row three-point contact angular ball bearing is provided which comprises an one-piece inner and outer rings, wherein at least one of the raceway surfaces of the inner and outer rings is made to form a Gothic-arched configuration having two curved surfaces, and each radius of curvature of the two curved surfaces is made to range substantially 0.51 to 0.55 of the outer diameter of a ball. And the other raceway surface of the inner and outer rings is made to have a single curved surface having a radius of curvature ranging substantially 0.505 to 0.56 of the outer diameter of the ball.
