随着进口机床的增加,在主轴及其滚动轴承的维修工作中往往会遇到一些技术问题,而机床使用说明书中又不作详细介绍、如:滚动轴承的精度、国产轴承的代用、主轴及壳体孔的技术要求、预加负载的数值、如何防止预加负载时的主轴变形等等。SKF轴承公司这份资料比较全面而定量地提供了上述答案,并给设计者提供了机床主轴和滚动轴承的合理结构。
With the increase of imported machine tools, some technical problems are often encountered in the maintenance work of the spindle and its rolling bearings, but the machine manual does not describe in detail. For example, the precision of rolling bearings, the substitution of domestic bearings, the main shaft and shell hole The technical requirements, pre-load values, how to prevent the pre-load spindle deformation and so on. SKF Bearing Company this information provides a more comprehensive and quantitative answer to the above, and to provide designers with a reasonable structure of the machine tool spindle and rolling bearings.
