[0002] Thrust ball bearings are designed to withstand thrust loads when running at high speeds. They are composed of a washer-shaped ring with a raceway groove for the ball to roll. Since the ring is seat-shaped, thrust ball bearings are divided into two types: flat seat pad type and self-aligning spherical seat pad type. In addition, this type of bearing can withstand axial loads, but not radial loads.

[0003] The existing planar thrust ball bearing is connected to the rotating structure through the inner thread ring on the seat ring, and the surface of the seat ring is smooth. When installing and disassembling the seat ring, it is inconvenient to fix the shaft ring, and it is inconvenient to exert force when rotating the seat ring, resulting in the planar thrust ball bearing being inconvenient to be quickly disassembled and maintained. In order to solve the above problems, the present application proposes a planar thrust ball bearing that is easy to disassemble and maintain. Utility Model Content

After the lifting seat 6 and the arc-shaped connecting frame 7 protrude from the surface of the seat ring 2, the seat ring 2 can be easily driven to rotate, thereby facilitating the rapid installation and disassembly of the seat ring 2.

[0030] In this embodiment, if Figure 3As shown, a countersunk fixing hole 11 is formed through the surface of the arc-shaped connecting frame 7, and a corresponding hole 13 is formed in the corresponding groove inner cavity at a position corresponding to the position of the countersunk fixing hole 11.
