Improvement to the Gear Reducer for a 45T Mining Car
Tooth broken, oil leaking and bearing burnt have influenced the original running of a 45T mining car which adopted one two-class gear reducer. In order to solve these problems, a three-class gear reducer was developed and its strength and stiffness were validated by using experience formulas and FEM. The sample of the three-class gear reducer was manufactured and tested in practical work for more than a half year. The results show that the three-class reducer works well, and the problems occurred in the two-class one can be resolved.
