Currently, the effect of the speed-reducing clutch of pulsator washing machine is usually band after the Double-directional rotary of motor is slowed down
Dynamic impeller does reciprocating rotation.Conventional speed-reducing clutch mainly by input shaft, output shaft, output sleeve, input axle sleeve, braked wheel,
The deceleration mechanism being mounted on inside braked wheel and the clutch components being mounted in input axle sleeve composition.When washing operating condition,
Output shaft low-speed bidirectional is asked to rotate repeatedly, output sleeve and braked wheel are an entirety, and deceleration mechanism, which generally only rises, simply to be subtracted
Speed effect, when braked wheel is braked, output sleeve is also braked, and driving motor bidirectional rotation can only drive output shaft accordingly double
To rotation.
Existing twisting speed-reducing clutch, internal reduction mechanism simultaneously have not been changed, and only change clutch control mechanism, by
Conventional list ratchet, single pawl, are changed to double ratchet wheels, double pawls, and when washing operating condition, braked wheel is tentatively unclamped (just complete when dehydration
It is complete to unclamp), driving motor bidirectional rotation drives the corresponding bidirectional rotation of output shaft, while output sleeve is because being braked, and by
Water flow reaction masterpiece rotation corresponding to output shaft opposite direction when output shaft rotates, corner very little, and by the resistance of clothing
Power variation, it is unstable that the revolving speed and the amplitude of oscillation of output sleeve change at any time.Though being formed to stranding phenomenon, and not up to ideal
Washing effect, and because the operating mechanism of brake band and double pawls is linkage, when washing, double pawls do not allow to leave ratchet
(just being left when dehydration), therefore when washing, brake band is only preliminary release, and separation is not thorough, and increases friction and the mill of brake band
Damage, improves the shaping and adjustment requirement to brake band.When dehydration condition, it is desirable that output shaft and output sleeve are whole as one
The unidirectional high speed rotation of body, to achieve the purpose that centrifugal dehydration.In order to convert the operating condition of washing and dehydration, conventional speed-reducing clutch must
Must be equipped with complete clutch parts such as ratchet, pawl, ratchet spring, brake spring, clutch axle sleeve, adjustment bolts, but itself is simultaneously

The rotation output of machine turns to rotations opposite, that speed is different for two, thus respectively drive impeller and interior bucket carry out it is contrary,
The different rotation of speed, and then play the role of carrying out clothing washing to washing by rubbing with the hands.The deceleration of existing washing machine bi-directional drive from
Planet fixed shaft gear train drive mechanism, gear transmission structure and Oscillating Tooth Gear Reducer structure is usually used in clutch, due to general gear
Transmission noise in the transmission of positive and negative twocouese is big, and to obtain manufacturing cost higher for Oscillating Tooth Gear Reducer structure, and therefore, planet fixed shaft gear train passes
Dynamic structure is widely used.

Input shaft, output shaft, output sleeve, input axle sleeve, braked wheel and the double drive gear mechanism composition being mounted on inside braked wheel,
Input shaft, output sleeve and output shaft are connected with double drive gear mechanism respectively, are equipped between braked wheel and output sleeve component
Arrangement of clutch.When washing operating condition, output shaft and output sleeve are mutually reverse, two-way to drive in proportion, repeatedly swing rotary, relatively
Strength rubs pendulum with the hands.When dehydration condition, is acted on by the locking of arrangement of clutch, output shaft and output sleeve can be made to combine automatically, simultaneously
Make the unidirectional continuous rotation of high speed, centrifugal dehydration.
But the washing machine with above-mentioned speed-reducing clutch is when washing operating condition, interior bucket with impeller is frequently opposite operates, it is interior
The moment of inertia that bucket generates acts directly on freewheel clutch, and with the increase of washing of drum type washing machine capacity, often because surmounting
Clutch is bad and quality problem occurs.Opposition often is generated to unilateral bearing in interior bucket rotary course, unidirectionally
Bearing is easy to appear failure phenomenon, while holding phenomenon tightly and clutch spring being caused to be damaged occur in clutch spring when just will appear washing；Separately
Outside, it is separated due to dehydrating shaft with braked wheel, and is connect with retarder, interior bucket generates the amplitude of oscillation under dewatering state, acts directly on
