Mounting sleeve for mounting a ring member on a shaft and a bearing assembly incorporating such a mounting sleeve

摘要

The present invention refers to a mounting sleeve (1) for mounting a ring having a tapering inner bore on a cylindrical shaft, wherein the mounting sleeve has a cylindrical inner envelope surface, wherein the inner surface of the mounting sleeve has an increased friction coefficient, for giving an increased ability to the mounting sleeve to transfer axial load, without sliding along the surface of the shaft.

主权项

1. A ring and mounting sleeve combination for mounting upon on a shaft,
said ring comprising a ring body having a tapered inner bore; and said mounting sleeve comprising a sleeve body having a tapering outer envelope surface, an inner cylindrical envelope surface, and a series of splines, said inner cylindrical envelope surface comprising a friction increasing treatment applied thereto so as to increase axial loading transferable by said mounting sleeve between said ring and said shaft while remaining axially fixed on said shaft; an axial force applicator, wherein, said ring and mounting sleeve combination is installed upon said shaft arranging said inner cylindrical envelope surface about said shaft and said ring about said mounting sleeve engaging said tapered inner bore with said tapering outer envelope surface, wherein, said axial force applicator drives said ring body in a direction towards a larger diameter of a tapered interface between said ring body and said mounting sleeve resulting in a compression force about a circumference of said sleeve body in a manner where said tapered inner bore generates a compressive force upon said tapering outer envelope surface, said compressive force contracts said inner cylindrical envelope surface, wherein friction provided by said friction increasing treatment increases said axial loading upon said cylinder shaft compared to an axial loading generated by said mounting sleeve prior to application of said friction increasing treatment.
