摘　　要：为了实现采煤机行走轮组件上行走轮某齿断裂后,不用拆解替换整个行走轮组件而直接更换断裂轮齿及重复利用轮毂,从结构设计角度,提出了一种轮齿可拆换的分体式行走轮。从结构设计、强度校核及预期效果等方面,对分体式行走轮进行了分析,理论认为这种可拆换轮齿的分体式行走轮结构具有可行性,为行业内提供了一种创新的行走轮结构。In order to directly replace broken sprockets and repeatedly use the hub instead of detaching and replacing the whole walking wheel after a certain sprocket of the walking wheel of the shear breaking,a split walking wheel with detachable sprocket was proposed from the point of view of structural design.In addition,from the aspect of the structural design,strength verification and predicted effects,the split walking wheel was analyzed.The split walking wheel with detachable sprocket was theoretically considered as feasible in structure.The research results offered innovative structure for the walking wheel in industry.
