The ring gear for a harmonic drive, harmonic drive with the ring gear, shafts adjusting device with the harmonic drive, as well as a process for the manufacture of the ring gear

摘要

Harmonic drive are able to realize very high transmission ratios. With this property, the harmonic drive, for example, as a camshaft adjuster and also as actuators for control of compaction can be used in internal combustion engines holds neps. This latter technology is also under the heading vcr (variable compression ratio) known.It is a ring gear 5 for a harmonic drive 6 a shafts adjusting device 1 with a ring gear section 19, wherein the ring gear section 19 has an internal toothing 11, is proposed, wherein the ring gear 5 is designed as a sintered body, the internal toothing 11 in the ring gear section 19 is introduced.
