摘　　要：无链牵引采煤机采用齿轨轮-销排机构,齿轨轮失效是造成无链牵引采煤机行走故障的主要原因。通过对齿轨轮常见失效形式的分析,从齿形设计、原材料、热加工质量、使用环境等方面进行改进,提高采煤机齿轨轮质量。The traction of chainless shearer uses a gear-pin-rail mechanism, and the failure of tooth rail wheel is the main reason for the walking fault of chainless shearer. By analyzing the common failure forms of tooth rail wheel, the tooth profile design, raw materials, hot processing quality and use environment were improved to stabilize the quality of tooth rail wheel of shearer.
