Abstract
The utility model discloses a double input power split differential planetary reducer. Power enters an input end gear pair from a double input shaft and is split by a differential inner gear ring and an input end driven gear and outputted from an output flange at a reduced speed through a composite motion of a differential planetary gear pair; smaller volume and bigger transmission ratio of the planetary reducer can be realized under conditions of the same strength, so that a machine structure is more compact; as for occasions such as a cement grinding mill and the like, a machine is made into a suspension type and coupled to a cylinder body of the mill directly by the output flange; a drive shaft is omitted; and only a torque stand on a casing of the machine is on the ground for balancing a rotating torque of the mill and absorbing influence of vibration and displacement of the mill on gears and bearings during operation so as to ensure reliable operation of the machine, thereby shortening arrangement size and reducing investment in infrastructure such as factory building and the like.
