门座式起重机传动装置主要由行走、回转、起升和变幅机构组成。其回转机构中,回转支承外齿轮连接机房与臂架系统、内圈连接转柱与门架,回转马达驱动门座式起重机上部回转。本文在分析门座式起重机回转支承外齿轮轮齿断裂原因的基础上,阐述其修复工艺。门座式起重机回转支承外齿轮如图1所示。1.轮齿断裂原因门座式起重机起吊重物时,其回转支承外齿轮承受较大的轴向、径向载荷和倾覆力矩,
Portal crane transmission consists of walking, turning, lifting and luffing mechanism. In the slewing mechanism, the slewing bearing external gear is connected with the engine room and the boom system, the inner ring is connected with the rotating column and the mast, and the revolving motor drives the upper part of the portal crane to revolve. Based on the analysis of the reason of the breakage of the external gear teeth of the slewing ring of the portal crane, the paper elaborates on its repair process. Rotary support outside the portal crane gear shown in Figure 1. 1. The cause of gear fracture When the portal crane lifting heavy objects, the slewing bearing external gear to withstand greater axial, radial load and overturning moment,
