Wear-resistant idle wheel gasket and wear-resistant reverse gear idle wheel structure

The wear-resistant idle wheel gasket is used for being clamped between a shell of the idle wheel structure and an idle wheel, the idle wheel is installed on a wheel shaft, the wear-resistant idle wheel gasket comprises a main body, the main body is provided with an inner hole, the main body is provided with a protrusion protruding out of the surface of the main body, and the inner hole is communicated with the protrusion. The protrusion is used for being matched with a clamping groove of the shell or a clamping groove of the wheel shaft. The main body is further provided with an oil groove, the oil groove is communicated with the inner hole, and the oil groove extends from the outer edge of the main body to the inner edge of the main body. According to the wear-resistant idle wheel gasket and the wear-resistant reverse gear idle wheel structure, when the wear-resistant idle wheel gasket is used, the protrusions can be matched with the clamping grooves of the shell or the wheel shaft, so that the protrusions c
