The drive gear is formed by a motor (7) with a worm (6), whereby the worm meshes with teeth (5) on the sleeve. The gearing consisting of the teeth on the sleeve and on the worm is self-locking. The drive gear may be hydraulically or electrically actuated. The drive gear is connected to the crankshaft bearing's oil supply via a piloted valve.",
