Abstract
Proposed is a planetary drive, having a rotationally driven sun gear ( ) disposed coaxially to principal drive axis ( ), with a an internal gear ( ) affixed within housing ( B) and possessing a rotatably supported planet carrier ( ), about which a plurality of circumferentially apportioned planet gears ( ) are rotatably seated, which are in complementary tooth engagement with the sun gear ( ) and with the internal gear ( ), whereby the planet carrier ( ) forms the output drive and in common with an output side output drive shaft ( ) is supported within the housing by an axially installed inclined bearing pair, comprised of a first inclined bearing ( ) and a second inclined bearing ( ). Further proposed is that at least the first inclined bearing ( ) is affixed with its inner ring ( ) in the housing ( A) and the outer ring ( ) of the bearing is to rotate with the planet carrier ( ) and having its pressure lines ( ) forming a pressure cone, the apex ( ) of which points away from the second inclined bearing ( ).
