Title: Ball bearing for hard disc drive device
Inventor: SHODA YOSHIO
IPC: H02K5/173
Filed: 2000-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a ball bearing capable of ensuring the durability, providing a structure free from the impression on a rolling contact surface of a ball 8, and reducing the fluctuation of torque. SOLUTION: An outer diameter D24 of a first shoulder part 24 of the first and second shoulder parts 24, 25 mounted on positions over an inner ring raceway 16a of an outer peripheral surface of an inner ring 17a, is diminished. Whereby a distance δ between an outer peripheral surface of the first shoulder part 24 and an inner peripheral surface of a rim part 19 of a cage 9 is ensured, which prevents the grease from being spread between both peripheral surfaces, and reduces the fluctuation of torque. As the rolling contact surface of the ball 8 can be prevented from running on an edge part of the inner ring raceway 16a for the sake of the increase of an outer diameter D25 of the second shoulder part 25, the impression is hardly remained.
