重慶升降機(jī)軸承套圈承受的負(fù)荷類組不同，選擇軸承配合的松緊程度也應(yīng)不間。承受局部負(fù)荷的套圈，局部滾道始終受力，磨損集中，其配合應(yīng)選松些。目的是讓固定式升降平臺套圈在振動、沖擊和，攘力矩的帶動下級轉(zhuǎn)位，以充分利用全部滾道并使磨拐均勻。從而延長軸承的壽命，但配合也不能過松，否劇會引起套圈在相配件上淆動而使結(jié)合面磨扭。對于旋轉(zhuǎn)精度有要求的場合，用不允許套圈轉(zhuǎn)位，以免影響升降平臺支承度。
Wenzhou lifting platform load on the bearing rings of different clusters, select the tightness of fit of the bearing should be no room. Ferrule to withstand partial load, force local raceway always wear concentrated loose some of its tie to be elected. The purpose is to allow the lifting platform rings fixed in vibration, shock and, Rang moment, driven lower translocation to take advantage of all races and mill turn evenly. Thus extending bearing life, but with not too loose, not drama will cause confusion ferrule fittings move on with leaving the joint surface grinding twist. For rotation accuracy requirements of the occasion, with ferrule indexing is not allowed, so as not to affect the degree of Wenzhou lifting platform support.
　
升降機(jī)承受循環(huán)負(fù)荷的套目，滾道各點(diǎn)循環(huán)受力，磨損均勻，其配合應(yīng)選擇緊些。因?yàn)楣潭ㄊ缴灯脚_套圈與軸頸或外殼孔之間工作時(shí)不允許產(chǎn)生相對滑動以免結(jié)合面磨損，并且要求在全日周上具有毯固的支承，以保證負(fù)荷能最佳分布，從而充分發(fā)揮軸承的承級力。
Wenzhou lifting platform subjected to cyclic loading sleeve mesh points race cycling stress, wear a uniform, which should be selected with some tight. Because fixed lifting platform between the ring and the journal work or housing hole allowed to combine in order to avoid relative sliding surface wear, and requires a solid blanket support in all-day week, in order to ensure optimal load can be distributed, to maximize Cheng level force bearing.
