A stripper for a threaded spindle has an essentially ring-shaped body, the inner circumference of which is provided with an internal screw thread (12) that works in cooperation with the carrier screw thread of the threaded spindle. The internal screw thread (12) has at least one recess (14) which is open towards the surroundings of the stripper and which interrupts at least one thread. At least one side edge of the recess (14) runs essentially cross-wise to the threads and is configured as a stripping edge (18), and the screw thread area (16) which carries the stripping edge (18) can be pressed into the carrier screw thread by means of a predetermined force. As a result of this stripper configuration, the topmost layer of the residual film of grease and the abrasive dust found on it can be accurately peeled off, even from the low part of the profile, so that layers of grease that are always clean lie at the points of contact between the shaft bush and the threaded spindle. As a result of the arrangement of additional spring means (20) for pressing the screw thread area (16), an automatic radial adjustment is realized so that the effect of the stripper is constant even when there is severe wear. |
