The at least two cover fasteners configured to connect the first section to the second section, and the at least one driveshaft fastener configured to connect the cover to the driveshaft or to a yoke of the driveshaft without any portion of the cover contacting the universal joint. The kits also include a plurality of inserts and/or a plurality of pads configured to allow the cover to adapt to driveshafts of varying diameters without changing the size or shape of the cover itself.

Cover for a universal joint of a driveshaft

A cover for a universal joint of a driveshaft comprises a first section, a second section, at least two cover fasteners, and at least one driveshaft fastener. At least a first cover fastener of the at least two cover fasteners is configured to connect a first section first edge to a second section first edge. At least a second cover fastener of the at least two cover fasteners is configured to connect a first section second edge to a second section second edge. The at least one driveshaft fastener is configured to connect the cover to the driveshaft or a yoke thereof without any portion of the cover contacting the universal joint.

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.
