1. In order to make the cage revolutionary movement stable; the ferrule guiding method should be selected as much as possible and the guiding surface should be given ample smoothness; the tapered roller bearing layout under high-speed working conditions should be improved; the roller-guided L-shaped cage should be changed. Z-shaped cage for ferrule ribs.
2, active selection of leading cleaning skills; useful complete removal of spare parts and products after the joint; improve the cleanliness of the bearing.
3. When the bearing rotates at high speed; the bearing amplitude of the bearing with large pocket gap is much larger than the oscillation amplitude of the cage with small pocket clearance; therefore, the value of the pocket void is especially important.
4, try to improve the accuracy of the cage production; improve the surface quality of the cage; help to reduce the noise of the roll and cage collision or conflict.
5, we must pay attention to minimize radial clearance.
