Abstract
The utility model relates to the field of speed reducer driving rollers, and discloses a planetary modularized driving roller device which comprises a speed reduction input shaft and a motor, the front section of the speed reduction input shaft is connected with a primary planetary device, the middle section of the speed reduction input shaft is connected with an output planetary device, and the rear end of the speed reduction input shaft is connected with the motor through a connecting sleeve. The primary planetary device is connected with the output planetary device through a sun gear; the primary planet device comprises a primary planet carrier, a primary planet wheel and a primary gear ring, the primary planet wheel is arranged on the inner ring of the primary gear ring and meshed with the primary gear ring, and the primary planet wheel is installed on the primary planet carrier; the output planet device comprises an output planet carrier, an output planet wheel and an output gear ring, the output planet wheel is arranged on the inner ring of the output gear ring and meshed with the output gear ring, and the output planet wheel is installed on the output planet carrier; the speed reduction input shaft is sleeved with a one-way bearing, the one-way bearing is provided with a bearing inner ring and a bearing outer ring, the bearing inner ring is matched with the speed reduction input shaft, and the bearing outer ring is matched with the output planet carrier; and the roller body is connected with the output gear ring. The one-way bearing, namely the non-return bearing, is adopted and directly acts on the input shaft of the speed reducer, and due to the fact that the one-way bearing is directly connected with the input shaft, transmission errors caused by gear meshing errors can be reduced.
