Analysis of Causes for Damage to Walking Wheel and Improvement Measures
In response to the problems of short service time and severe tooth surface wear during the use of the walking wheel of shearer in a certain mine,factors has been preliminarily determined,such as the wear of guide shoe,severe damage to the local tooth shape of the pin-rail,and scraper conveyor moving too quickly.A 3D software was used to construct the meshing model of the pin teeth,and dynamic and strength analysis were conducted on the above-mentioned influencing factors as the research object.Based on the on-site situation,the cause of damage was determined,and suggestions for reducing damage to the walking wheel were given.After improvement,the walking wheel no longer experienced the serious short-term wear problem,and the effect was proved to be efficient.
