微型球轴承保持架并不分担轴承的负荷,它的主要作用是把钢球分隔开。在工作过程中它会受到下列三种力的作用,即轴承的加速度所造成的惯性力,某些用途中的冲击力和高速下的离心力。而离心力有可能使保持架松开,沿轴向活动,有时甚至会把保持架甩出轴承。 Miniature ball bearing cage does not share the bearing load, its main role is to separate the ball. It is subjected to the following three forces during work: the inertia caused by the acceleration of the bearing, the impact force in some applications, and the centrifugal force at high speeds. Centrifugal force may make the cage loose, axially movable, and sometimes even the cage thrown out of bearings.
