The cause on wear for splint of sliding shoe milland design of self- positioning sliding shoe bearing

Starting from the present situation of wear for splint of large sliding shoe mill and its influence on the mill running,the mechanism of splint wear were analyzed,and the structure design of selfpositioning sliding shoe bearing were proposed which were solving the problem of splint wear.Through computing the examples of mechanical equilibrium,the key technology of design on self-positioning sliding shoe bearing were solved which were determined for Toba inclination of sliding shoe bearing.And the benefits for self- positioning sliding shoe bearing design technologies were assessed through the use of comparative method.It was concluded that the use of self-positioning sliding shoe bearing of small cone angle which can avoid the splint mill wear and traverse of grinding body caused by the axial force of fundamentally,and solve problems that should not be used to helical gear for the sliding shoe mill.At the same time,it can improve the stability and carrying capacity of helical gears transmission on the sliding shoe wear,and enhance the efficiency of grinding.
