Description

Technical Field

[0001] The utility model relates to the technical field of thrust washers, in particular to a corrosion-resistant thrust washer. Background Art

[0002] Thrust washers are flat, disc-shaped components that are usually used to reduce friction, bear axial loads, and protect metal parts of bearings. Thrust washers are made of the following materials: copper alloy, carbon steel, stainless steel, plastic, composite materials, etc.

[0024] See also Figures 1 to 3 In an embodiment of the present utility model, a corrosion-resistant thrust washer includes a gasket body 1, wherein an upper annular groove 2 and a lower annular groove 3 are respectively formed on the upper and lower surfaces of the gasket body 1. A plurality of the upper annular grooves 2 and the lower annular grooves 3 are provided on the upper and lower surfaces of the gasket body 1, and the plurality of upper annular grooves 2 and the lower annular grooves 3 are staggeredly distributed from the outside to the inside.

[0025] The upper annular groove 2 and the lower annular groove 3 are provided to reduce the overall weight of the gasket body 1;

[0034] In this embodiment: through the arrangement of the upper annular groove 2, the lower annular groove 3, the first straight notch 4, and the second straight notch 5, the gasket body 1 is lighter than the traditional solid circular ring state stainless steel thrust washer. At the same time, through the filling of the upper annular groove 2, the lower annular groove 3, the first straight notch 4, and the second straight notch 5 by the plastic filling part 6, the gasket body 1 has good anti-deformation force, and the gasket body 1 can also assist in enhancing the mechanical strength of the plastic filling part 6.
