ABSTRACT:
The expandable annular cam-type locking device is particularly applicable for use on mill roll necks, shafts and the like. The annular locking device is adapted to be disposed in an annular groove of a mill roll neck or shaft for retaining one or more sleeve-like members, anti-friction bearings, seals, spacers or the like together as a unit against a fixed abutment of the shaft for maintaining the member or plurality of members in proper working or spaced relationship on the shaft. The annular locking device comprises a pair of annular members or segments each having a pair of flat surfaces. One or more circular recesses is located in one surface of each annular member and each recess is provided with an expandible circular cam insert having flat faces. Threaded fastening elements are carried by the annular members and are threadedly connected to the inserts for expanding or moving same relative to the recesses. With such a construction, when the annular members are disposed about a shaft, the rotation of the threaded fastening elements in one direction urge the inserts against the sleeve-like elements, bearings or the like and in turn against the abutment provided on the shaft so as to locate and maintain the various elements on the shaft in the required working relationship.
