Ball screw drive with deflection part having hollow chamber with lubricant-absorbent material and weep holes into bypass channels

摘要

The ball screw drive has a deflection part with an internal hollow chamber containing a lubricant oil store. The part has one or more weep holes, to connect the hollow chamber to a bypass channel. The chamber contains oil-absorbent plastic material, which projects from the weep holes into the channels. It also contains a fastener peg. This engages on the material to regulate the distribution speed of the oil. The deflection component consists of two plastic parts, which are connected via an ultrasonic connection with flange.
