Apparatus for mounting and dismounting bearings

A device for mounting and/or dismounting a bearing on a shaft having a longitudinal axis, comprising a tapered clamping sleeve provided between the bearing and the shaft, the bearing having inner and outer races;

• displacing means for effecting relative axial displacement between the bearing and clamping sleeve in at least one axial direction, said displacing means including at least one wedge-pointed screw arranged, when being screwed in towards the shaft, to produce a relative displacement in the axial direction between the clamping sleeve and the bearing by wedge action;
• the bearing being situated in a bearing housing surrounding the outer race, the bearing housing including first and second axially spaced end surfaces facing in opposite axial directions, the first and second end surfaces situated radially outwardly of the bearing and defining first and second end planes oriented substantially perpendicular to the shaft axis;
• the displacing means further including a flange axially affixed to the clamping sleeve and projecting radially therefrom;
• the at least one wedge-pointed screw being arranged to be screwed about an axis of rotation extending non-parallel to said shaft;
• said at least one wedge-pointed screw including radial inner and outer ends, said radial inner end being wedge-pointed and arranged to exert said axial wedge force between the flange and the inner race of the bearing at a location disposed axially between said first and second end planes;
• said axis of rotation coinciding with an axis of a screw access hole formed in said outer housing at a location disposed axially between said first and second end planes.
