Harmonic drive for a camshaft adjusting device, as well as camshaft adjusting device with the harmonic drive

摘要

Harmonic drive transmission - or are transmission gear, which are constructed from a few subassemblies. It is a harmonic drive 6 for a camshaft adjusting device 1, with a well generator 7, a spur gear device 8 and a ring gear 5, wherein the well generator 7 an oval basic body as well as a radial bearing device 10, wherein the radial bearing device 10 has an outer ring 18, a inner race 21 and a plurality of rolling elements 20, wherein the rolling elements 20 between the outer ring 18 and the inner race 21 rollingly are arranged, so that the rolling elements 20 a first connector part and the inner race 21 form a second contact partner, the spur gear means 10 has an external tooth system 9 and with the radial inside to the outer ring 18 of the radial bearing device 10 and is designed so it can be deformed in such a way that the generator 7 by the well can be deformed, wherein the ring gear 5 carries an internal toothing 11, the internal toothing 11 only partially with the external tooth system 9 is engaged, wherein one of the contact partners, a ceramic contact surface 22 has to the other contact partner.
