Claims

[Scope of utility model registration request]

A rotating type crusher in which an eccentric drive shaft supporting a rotating mantle is radially supported in a cantilevered manner at the lower part of the eccentric drive shaft, and the mantle is axially supported by the eccentric drive shaft via a thrust bearing. In the shaft support structure of the machine, the bearing surface of the thrust bearing is divided radially in the circumferential direction, and the bottom surface of one of the bearing plates constituting this thrust bearing is made into a spherical surface, and this spherical surface is connected to the main axis of the mantle. Or a shaft support structure for a rotary crusher, characterized in that the shaft is brought into contact with a spherical seat attached to an eccentric drive shaft, and the bearing plate having the spherical bottom surface and the spherical seat are connected while allowing a slight deviation. .
