SYSTEM AND METHOD FOR HYDRAULICALLY REMOVING A SOCKET FROM A MAINSHAFT OF A GYRATIONAL CRUSHER

摘要

A hydraulic separation system for use in a gyrational crusher to separate a socket of the crusher from a main shaft. The hydraulic separation system includes one or more hydraulic grooves formed at the interference contact area between the socket and the main shaft. Each hydraulic groove is fed with a supply of pressurized hydraulic fluid to aid in separation of the socket from the main shaft. An inner contact surface of the socket is tapered and engages a tapered outer surface of the main shaft. The mating tapered surfaces further aid in separation of the socket from the main shaft upon application of the pressurized hydraulic fluid.

主权项

1. A gyrational crusher, comprising:
a stationary bowl; a head assembly positioned for movement within the stationary bowl to create a crushing gap between the stationary bowl and the head assembly; a main shaft having a top end and an outer surface, wherein the head assembly gyrates relative to the main shaft; an eccentric rotatable about the main shaft to impart gyrational movement to the head assembly within the bowl; a socket mounted to the top end of the main shaft; and a hydraulic separation system operable to separate the socket from the top end of the main shaft.
