Coal Mining Machine Travelling Wheel Tooth Surface Wear Problem Analysis and Improvement
In view of the serious wear problem of the travelling wheel of WG-2×125/571-WD coal mining machine,an analysis of the causes of the travelling wheel wear problem was carried out,and the results showed that fatigue wear was the cause of the serious wear of the travelling wheel.After that,the modulus of the travelling wheel was optimized and improved,and the results showed that after the improvement,the maximum contact stress value of the travelling wheel in the working process was reduced,the fatigue stress state of the travelling wheel was improved,and the fatigue life of the travelling wheel was increased,and the effect of the improvement was quite remarkable.
