造成升降平臺主軸斷軸的原因很多，大多數(shù)屬于使用不當，總結(jié)一下主要有以下幾方面的原因。

1、升降機長期超負荷運行，特別是因使用維護不當造成外傷產(chǎn)生裂紋，而又長期超負荷使用。
Hangzhou lifting platform long-term overload operation, in particular the use of cracks caused by improper maintenance of trauma, but the long-term overload.

2、主軸滑動配合表面潤滑不良，升降平臺在長期缺油的情況下運行，造成主軸磨損，出現(xiàn)較大的應(yīng)力集中情況，進而出現(xiàn)疲勞裂紋，在沖擊載荷作用下，最后出現(xiàn)主軸斷裂。
Spindle sliding surface with the poor lubrication, Hangzhou lifting platform in the long run short of oil, the wear and tear caused by the spindle, large stress concentration occurs, then there fatigue cracks in the impact loading, last seen spindle fracture.

3、裝拆主軸上的零件時打傷或碰傷主軸，使主軸出現(xiàn)裂口，成為裂紋源，裂紋不斷擴展，最后造成升降平臺主軸斷軸，裝齒輪聯(lián)軸器的軸肩處是主軸最弱的部位，應(yīng)力最高，最易在此處出現(xiàn)斷軸事故。
Parts assembly and disassembly spindle wounded or bruised spindle, spindle cracks appear and become a source of cracks, crack continues to expand, and finally result in Hangzhou lifting platform off the spindle shaft, shoulder mounted gear coupling is the weakest of the spindle site, the maximum stress, the most easily broken shaft accident occurs here.

4、為避免斷軸事故的發(fā)生，杭州升降平臺在使用過程中要嚴禁超負荷使用。維修人員必須定期檢查固筒左支輪、游簡左支輪、游筒右 支輪與主軸滑動配合表面的潤滑情況。維修人員在拆裝主軸上的相關(guān)零件如齒輪聯(lián)軸器、固筒右支輪等處的切向健、游動卷筒的銅瓦時，嚴禁打傷或碰壞主軸。
To avoid breaking the shaft of the accident, in the course of the lifting platform to be prohibited overload. Maintenance personnel must be checked regularly left branch of the solid cylinder wheel, amusement Jane left outrigger wheels, swim tube slide right branch wheel and spindle mating surface lubrication. Maintenance personnel in the relevant parts such as spindle disassembly gear couplings, solid right branch wheel cylinder tangential health, etc., when the roll of copper tile swimming is prohibited wounded or damage the spindle.
