1台履带式工程机械使用一段时间后,其右侧履带的链轨外侧护轨板连接螺栓即出现断裂现象,同时右侧的11只支重轮外侧轮缘均出现不同程度的“啃轨”现象。“啃轨”严重的支重轮轮缘已出现破裂现象,且右侧链轨节外侧及链轨销轴的端部也出现严重磨损,而左侧履带、支重轮的磨损正常。1.原因分析分析认为,造成支重轮啃边及链轨磨损可能有以下5种原因:(1)履带张紧度不够当该工程机械转向时链轨产生横向弯曲,造成支重轮轮缘压至链轨节上表面,从而导致支重轮轮缘严重磨损。(2)支重轮中心偏移
After a track-type construction machinery is used for a period of time, the connecting bolt on the outer side of the track rail of the track on the right side of the track is broken, and the outer rim of the outer wheel of the 11 track wheels on the right side appears different degrees of “ ”phenomenon. “Gnawing rail ” Serious wheel flange has ruptured, and the right side of the chain link and the end of the chain link pin also serious wear and tear, while the left crawler, roller wear normal. 1. Analysis and analysis of the reasons that cause rucksack and chain link wear track wear may have the following five reasons: (1) track tension is not enough when the construction machinery when the steering column lateral bending, resulting in roller flange Pressure to the upper surface of the link section, resulting in serious wear wheel flange. (2) Track roller center offset
