US Patent 7210375 Unitary case for an angular drive

The application relates to a unitary case for a plurality of angular drives which comprises at least one bevel gear step with a first bevel gear and a second bevel gear, and which is provided for achieving various angles between a transmission input shaft and a transmission output shaft. The second bevel gear is coupled to the transmission output shaft in an indirect rotationally fixed manner. The unitary case is designed for a plurality of possible angular outputs wherein multiplication is substantially constant and the outer diameters of the individual bevel gears are substantially identical.
