Worm/toothed-rack gear

摘要

The invention relates to a worm/toothed-rack gear using an essentially straight toothed rack, which gear is suitable in particular for use in adjustment devices for motor vehicles and is distinguished by a particularly low production of noise. The gear according to the invention is characterised in that at least the ends of the worm have convexly shaped run-in areas. Preferably, both edges of the start of the toothing of the worm are set back radially in the direction of the axis of the worm. Such worms can be manufactured particularly advantageously with a negative milling device. <IMAGE>
