The invention discloses a two-way drive gear reducer and a washing machine with the gear reducer. The gear reducer includes a casing composed of a casing and an end cover arranged at one side of the casing, an input shaft, and a first output shaft. and the second output shaft, the input shaft and the first output shaft are coaxially arranged, the second output shaft is a hollow shaft, and coaxially sleeved on the outside of the first output shaft, one end of the input shaft located in the housing is connected to a single The sun gear of the planetary row is connected, and a meshing ring gear is provided outside the single planetary row. A central gear meshes with internal teeth, and the second output shaft is provided with a second central gear at one end of the casing, and the first central gear drives the second central gear through a multi-stage gear transmission system. The invention has the characteristics of compact structure, convenient layout, high integration and convenient assembly.
Description
technical field [0001] The invention relates to a washing machine and its transmission mechanism, in particular to a gear reducer with two output shafts with different directions and speeds and a washing machine with the gear reducer. Background technique [0002] At present, the function of the deceleration clutch of the pulsator type washing machine is generally to drive the pulsator to reciprocate after decelerating the bidirectional rotation of the motor. The conventional deceleration clutch is mainly composed of an input shaft, an output shaft, an output shaft sleeve, an input shaft sleeve, a brake wheel, a reduction mechanism installed inside the brake wheel, and a clutch component installed on the input shaft sleeve. In washing conditions, the output shaft is required to rotate repeatedly at low speed in both directions. The output shaft sleeve and the brake wheel are integrated. The deceleration mechanism generally only plays a simple deceleration role. When the brak...
