Description
Technical field
The present invention relates to washing machine technology field, in particular it relates to a kind of washing machine direct driving motor and speed-reducing clutch.
Background technology
Two-power washing machine is a kind of novel pulsator washing machine, it is mainly characterized by when washing, the interior bucket of washing machine and impeller can in a reverse direction, different rotating speeds rotates, make what washings was subject to interior bucket and impeller in the process of washing reversely to turn power, play and washings is carried out to washing the effect washed by rubbing with the hands, washings wash cleanliness is higher.
Washing machine interior bucket and impeller when washing rotate backward and mainly rely on the speed-reducing clutch of washing machine to realize, the speed-reducing clutch of existing washing machine bi-directional drive is usually employing planet fixed shaft gear train drive mechanism, gear drive and movable tooth drive mechanism, owing to general gear drive noise when positive and negative Bidirectional driving is big, and the manufacturing cost of movable tooth drive mechanism is high, therefore, planet fixed shaft gear train drive mechanism is widely used.
