Patent ID: 6889572

Claim:
An angle drive comprising: a housing; a hollow input shaft which is supported in the housing, and which carries an input ring gear and is positioned on a first axis (A 1 ); an output shaft which is supported in the housing, and which carries an output gearwheel and is positioned on a second axis (A 2 ) which intersects the first axis (A 1 ) at a right angle; a counter ring gear which is supported on the input shaft by a radial bearing and an axial bearing respectively, and, which is positioned on the first axis (A 1 ) and which, with reference to the second axis (A 2 ), is arranged and designed symmetrically relative to the input ring gear; and two intermediate gearwheels each supported in the housing and arranged on an axis (A 3 , A 4 ) positioned radially relative to the first axis (A 1 ) and in the same plane as, and forming identical pitch angles with, the second axis (A 2 ), each intermediate gearwheel having the same type of toothing as the output gearwheel; wherein the counter ring gear is supported so as to be independently rotatable relative to the input ring gear, and wherein the input ring gear and the counter ring gear are crown wheels which, via their respective teeth, simultaneously engage the output gearwheel and each intermediate gearwheel, the output gearwheel and the intermediate gearwheels being spur gears with straight or helical toothing; wherein the housing comprises a spoke supporting a hub extending coaxially with the first axis (A 1 ) and wherein the input shaft is supported by the hub; and wherein the intermediate gearwheels each run on respective rotary journals supported at one end by the housing and at another end by the hub.
