转盘轴承是一种能够同时承受较大的轴向负荷、径向负荷和倾覆力矩等综合载荷，集支承、旋转、传动、固定等多种功能于一身的特殊结构的大型轴承。因此，在安装转盘轴承时一定做好相关性的检查工作，或者安装时需要注意的事项，对于这种大型轴承来说，我们一定要做好保养、存储等工作，以免转盘轴承发生以下损坏，导致无法正常使用。 Wheel bearing is a kind of can bear larger axial load, radial load and tilting moment, a comprehensive load bearing, rotating, transmission, fixed, and other functions in one of the special structure of large bearing. As a result, the wheel bearing when installation to must do the inspection of the correlation, or matters need to pay attention to when installation, for the large bearing, we must do a good job, maintenance, storage, and so on in order to avoid had the following wheel bearing damage, lead to can't normal use. 1、转盘轴承的安装 The installation of rotary bearings 转盘轴承安装前，先要对主机的安装面进行检查，要求支承件应具有足够的强度，连接面应机械加工，表面平整无杂物和毛刺。对于无法进行机械加工达到所要求的平面度的，可以采用注入强度大的特殊塑料做填充物，来保证安装平面的精度和用以减振。 转盘轴承的套圈有淬火软带区，这在套圈的端面上均有标记“S”，安装时应使该软带位置置于非负荷区或非经常负荷区（塞子孔总是位于软带处）。 Wheel bearing before installation, check the mounting surface of the host first, request support should have sufficient strength, junction surface should be mechanical processing, surface smooth without sundry and burr. Mechanical processing for unable to meet the requirements of planeness, can use special plastic filler injection intensity, to ensure the accuracy of the installation plane and for vibration reduction. Wheel bearing ring with quenching soft belt region, in the ring on the face of all marked "S", when installation should be in the position of the soft belt on the load area or not often load section (plug hole is always located on the soft belt).
