Abstract
A metallic sleeve () may be pressed with relatively low axial forces onto a softer metallic shaft () to produce a permanent interference fit between the sleeve and the shaft even if subject to high torque loads. For this purpose, the sleeve incorporates a plurality of successively reduced diameter, axially spaced, arrays () of splines () within its interior, with a series of spaced circumferentially extending grooves () situated between the arrays. The arrays of splines define angled frontal cutting edges () adapted to cut into the metal shaft for rigid securement of sleeve to shaft. The spaced grooves are adapted to collect chip debris () during installation of the sleeve to the shaft, each groove providing a volumetric space to provide for the uniform distribution of chip debris within the interface of sleeve and shaft.
