ABSTRACT:
A conveyor roller comprises a steel roller tube fitted with end cap assemblies incorporating bearings for rotatably mounting the roller tube on a fixed shaft. Each end cap assembly comprises a rigid housing which supports the bearing, and a separate collar of resilient plastics material mounted on the housing. The axially inner end portion of the collar has an annular recess which receives a radial flange on the housing, and the axially outer end portion of the collar consists of inner and outer tubular walls which are spaced apart prior to fitting of the end cap assembly in the roller tube. The external surface of the inner tubular wall is curved radially inwards and axially outwards. Each end cap assembly is secured in position by swaging the end of the tube so as to force the outer wall of the collar against the inner wall along its length. The inner tubular wall of the collar may be of any suitable thickness, so that the end cap assembly can be adapted to fit roller tubes of different diameters by fitting the housing with a collar with an inner tubular wall of appropriate thickness. The radial flange on the housing may be formed with teeth and the axially inner end portion of the collar formed with tongues which project between the teeth so as to lock the collar to the housing for rotation therewith. In a construction in which the housing is made of steel, the teeth may engage the roller tube to provide an electrically conducting path therebetween for static electricity, or alternatively a wire of electrically conducting material may have one end clamped between the collar and the housing and the other end clamped between the collar and the roller tube.
