Abstract
The utility model relates to the technical field of a transmission part, in particular to a ball bearing. The ball bearing comprises an outer bearing housing, an intermediate bearing housing, a ball I, an inner bearing housing, a ball bearing II, a ring-shaped raceway I and a ring-shaped raceway II, wherein the ball I is arranged between the outer bearing housing and the intermediate bearing housing, the ball II is arranged between the intermediate bearing housing and the inner bearing housing; the ring-shaped raceway I is arranged between the outer bearing housing and the intermediate bearing housing; and the ring-shaped raceway II is arranged between the intermediate bearing housing and the inner bearing housing. The ball bearing is simple, compact and reasonable in structure, convenient and fast to assemble, reliable in connection, excellent in centering property, is capable of bearing high radial load and axial load, and is small in friction resistance, so that the cost of the ball bearing is reduced, the service life of the ball bearing is prolonged, the working reliability of the ball bearing is greatly improved, and the ball bearing is easy to use and popularize.
Description
Technical field
The utility model relates to a kind of technical field of driving component, especially a kind of ball bearing.
Background technique
Existing ball bearing is installed and changes cumbersome, has improved the cost of mechanical erection, and centering is poor, is difficult to bear larger radial load and thrust load, and surface friction drag is large, has shortened the working life of ball bearing, greatly reduces the reliability of ball bearing work.
