Abstract
A gear-drive assembly between an input shaft (17, 117) and an output shaft (10, 110) comprises a ring gear (12, 112) having a peripheral portion provided with corresponding and opposite toothings (14, 15, 114, 115) on the two faces thereof. Meshing with each toothing (14, 15, 114, 115) is a pinion of a pair of pinions (16, 25, 116, 125) carried by parallel shafts (17, 22, 117, 122) interconnected with each other by a driving gear (20, 21, 120, 121) to rotate at the same speed and in opposite ways. One of said parallel shafts is the power-input shaft (17, 117). The ring gear (12, 112) is carried by the output shaft (10, 110) in a floating manner to vary the distance of its toothings (14, 15, 114, 115) from the axis of the pinions (16, 25, 116, 125).
