Abstract
A self-aligning dust seal assembly for rock crusher machines and particularly gyratory crusher machines has a dust seal and a seal guide that extends from the dust seal in a cone shape to enable alignment of the dust seal when the main shaft is lowered into position. The dust seal has a body portion that is disc shaped. There is an inner seal surface around the inner perimeter of the dust ring that seals against an inner element of the crusher. The seal guide extends down and outward from a connected portion with the dust seal that is proximal the inner perimeter of the dust seal. The seal guide is cone shaped and extends outward in a convex shape from the connected portion. The cone shape of the seal guide may nest on a corresponding flange that is fixed in the rock crusher machine, for example.
