Sealed crusher
First Claim
1. A gyratory crusher havinga frame;
- an eccentric shaft rotatable around a vertical axis in the frame, with a vertical inclined hole therein;
a main shaft supported by bearings in the hole of the eccentric shaft, said main shaft comprising an upper end extending above the eccentric shaft, and a supporting cone attached and supported thereto, andarranged around the main shaft, below the supporting cone, a sealing cover covering the eccentric shaft, said sealing cover having an inner edge, and an outer edge fastened tightly to the frame,whereby the sealing cover is sealed against the main shaft with a sealing member so that contact surfaces between the sealing cover and the sealing member are formed in an annular groove and a part fitted in the groove, said groove having the shape of the part fitted in the groove, but being sideways wider than the portion of said part fitted in said groove,wherein the contact surfaces of both said groove and the part fitted in said groove are inclined in such a way that radially outer edges of said groove and the part are higher than radially inner edges of said groove and the part.

Abstract
A gyratory crusher having a frame (1) and in the frame an eccentric shaft (3) rotatable around a vertical shaft in the frame, with a vertical inclined hole in it. A main shaft (4) is supported by bearings in the hold of the eccentric shaft, a supporting cone (5) being attached to the upper end of said main shaft (4). Around the main shaft, below the supporting cone (5) there is a sealing cover (10) covering the eccentric shaft. The upper edge (12) of the sealing cover (10) is sealed against the main shaft (4) by means of a sealing member (13), the outer edge of which has been fitted in an annular groove (17) on the inner edge (12) of the sealing cover (10). The face-to-face arranged upper and lower surfaces so the part (13") of the sealing member (13) in the groove and the groove (17) of the sealing cover (10) are inclined so that their outer edges are higher up than their inner edges.
