A differential gear type reducer with compact structure can get a relatively large reduction ratio through mechanically controlling rotational braking of the differential gear device (10) together with an input shaft (3). The input shaft and an output shaft (4) are in linkage connection through the differential gear device arranged in a gearbox (1). A brake (35) is arranged at one end of an adjusting shaft (30) in parallel with the input shaft and a clutch (36) is arranged at the other end. A first level pinion (21) fixed in the input shaft is engaged with a first level gear (22) rotatably arranged in the adjustment shaft and the first level gear is in linkage connection with the clutch in an engaged and comfortably disengaged way. A second level pinion (gear) (24) fixed on a shell (11) of the differential gear device is engaged with the second level gear (pinion) (23) fixed on the adjusting shaft. Through a switch operation of the brake and the clutch, the adjusting shaft and the input shaft are enabled to rotate/stop in a ganged way, so as to control the rotational braking of the differential gear device. |
