前言这是一篇很少见到的有关穿过滚动轴承磁通的影响的文章。这种影响由于机械力或发热,会引起轴承过早地损坏。好在这一问题只在数目有限的情况里是严重的,而且一般与产生轴向磁通的电机有关。本文概述其物理作用,并提供一些试验结果来说明其影响。磁通在轴承中的影响虽然在各种轴承中均会出现这种影响,但最初考虑安装在电机机座内的深槽滚珠轴承所支承的轴的情况。转轴带有横向磁通,该磁通径向地穿越轴承,並围绕机座使磁路连通。穿过轴承的磁通会产生吸引力、磁滞 Preface This is a very rare article about the influence of magnetic flux across rolling bearings. This effect due to mechanical or heat, can cause premature bearing damage. Fortunately, this problem is serious only in a limited number of cases, and is generally related to the motor that produces axial flux. This article outlines its physical role and provides some experimental results to illustrate its impact. Effect of Magnetic Fluxes in Bearings Although this effect can occur in a variety of bearings, initially the shaft supported by deep groove ball bearings mounted in the motor housing is considered. The shaft carries a transverse flux that traverses the bearing radially and surrounds the housing to make the magnetic circuit communicate. The magnetic flux that passes through the bearing will generate attractive, hysteresis
