[0002] The bearing plays the role of fixing and reducing the friction coefficient of the load in the process of mechanical force transmission. The bearing can not only bear the load of the shaft, but also has the function of reducing friction and vibration. For the balance bearing used in heavy-duty vehicles, due to The load of the vehicle is heavy, the road conditions are complex, and the working conditions are poor. Therefore, the forces acting on the balance shaft bearings include not only axial force and radial force, but also various composite forces and impact forces, especially in ordinary balance bearings. The surface wear resistance is poor, and the lubrication conditions are poor, the friction coefficient is large during operation, and the inner wall of the bearing is easy to wear, resulting in frequent damage to the balance shaft bearing
