Date Nov. 23, 1995A driving unit comprising an electric motor and a reduction gear unit preferably intended for an industrial robot. A gear case (11) supports a motor (10) with a shaft (12) extending into the gear case and provided with a bevel pinion (13). An intermediate shaft (15) is rotatably journalled with two bearings (16). On the intermediate shaft are fixed a larger bevel gear (14) and between the bearings a smaller cylindrical gear (17). An output shaft (20) provided with a larger cylindrical gear (18) is rotatably journalled and parallel with the intermediate shaft (15). The gears are arranged such that the bevel pinion (13) is in engagement with the larger bevel gear (14) and the smaller cylindrical gear (17) is in engagement with the larger cylindrical gear (18). The motor shaft (12) is oriented approximately perpendicular to the output shaft (20). |
