Abstract
Abstract An apparatus for the fixing of bearing assembly having a conical bore about a cylindrical shaft. A relatively thin walled sheetlike sleeve is provided surrounding the shaft within the inner bore of the bearing. The sleeve is provided with radial outward projections and an annular wedge member is seated therein. The wedge has a conical surface and a cylindrical surface corresponding to those of the bearing and the sleeve. Compression means are provided to act against the frontal end of the wedge and one of the projections to urge the wedge compressively against the conical inner bore.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
119 words
Apparatus for mounting a machine part such as a roller bearing assembly having a conical inner bore on cylindrical shafts, axles or the like, comprising a sleeve adapted to be interposed about said shaft within the machine part, said sleeve having retaining means projecting outwardly at the ends thereof, an annular wedge surrounding said sleeve having a conical surface and a cylindrical surface corresponding to the inner bore of the machine part and sleeve respectively, and compression means abutting against the frontal end of said wedge and against one of said radially projecting means to urge said wedge on said sleeve compressively against the conical inner bore when said wedge is interposed between the machine part and said sleeve.
