Background

At the moment when the engine stops working, the crankshaft of the engine has a transient forward and reverse direction swing, and the rotor of the engine still keeps rotating in the original direction at the moment, so that the damage of a magnetic coil in the rotor caused by forward and reverse impact is avoided, and a one-way wheel is used and fixedly arranged on the rotor. The one-way wheel can be divided into a wheel shell and a shaft core, and the shaft core is connected with the wheel shell through a one-way bearing. If the rotating speed of the shaft core exceeds the rotating speed of the wheel shell in operation, the one-way wheel slips immediately, so that the impact is reduced, the effect of protecting the transmission mechanism is achieved, and the service life of the transmission mechanism can be effectively prolonged.

However, because balls and lubricating oil between the inner layer and the outer layer of the one-way bearing are relatively waterproof, in the existing one-way wheel, rubber or steel sealing structures are arranged on two sides of the one-way bearing to protect the one-way bearing. However, after the one-way wheel works for a long time, because the rotating speeds of the shaft core and the wheel shell are different frequently, and in addition, the vibration of the outside to the one-way wheel is added, the common sealing washer is made of steel, the structure is hard, the abrasion is not easy to occur due to good hardness, but the sealing performance is poor, so that the bearing in the one-way wheel is easy to leak oil and damage, the elasticity of the rubber gasket is good, the hardness is not enough, the bearing is easy to deform and leak oil, the abrasion of the rubber or steel sealing structure is fast, the bearing leaks oil, and. To this end, we propose a one-way wheel fitted with a composite sealing gasket.
