Gearbox with high gear ratio

摘要

A gear box with high ratio with a reducer and a differential gear consists of a input shaft (1), that is firmly coupled with a idle wheel (31) of a reducer (3) and freely rotates in a gearbox (5). The idle wheel (31) of the reducer (3) meshed with a bevel wheels (32, 33) of the reducer (3), which have a different number of teeth. The bevel wheel (32) of the reducer (3) is firmly coupled with a idle wheel (42) of a differential gear (4) and freely rotates on a output shaft of a gearbox (2). The bevel wheel (33) of the reducer (3) is firmly coupled with a idle wheel (43) of the differential gear (4) and freely rotates on the output shaft of gearbox (2). The bevel wheels (42, 43) that have the a same number of teeth meshed at least a one satellite (44), which is freely rotating on a pinion carrier (41), which is firmly coupled with the output shaft of the gearbox and a output shaft is freely rotates in the gearbox (5).
