Abstract
A mechanism for transferring a rotary motion into an axial motion. The assembly includes a shaft having a smooth, cylindrical envelope surface, a retainer enclosing the shaft and rotatable relative the shaft. A plurality of bearing housings with bearing seats inclined towards the shaft are arranged in the retainer. Bearings having outer and inner race rings are arranged in the bearing seats. The bore diameter of the inner race rings, which are arranged to enclose the shaft, are larger than the diameter of the shaft. The bearing seats are designed completely to enclose the outer race rings of the bearings. The retainer has a recess having opposing sidewalls defining guide surfaces. The bearing housings are slidable in and guided by the sidewalls of the recess for displacement substantially perpendicularly to the shaft. The bearing housings are subjected to a force in the direction of displacement so as to urge the inner race rings of the bearings against the envelope surface of the shaft.
