Description

Reducing gear clutch for full automatic washing machine
Technical field
The present invention relates to a kind of deceleration clutch of washing machine, especially a kind of reducing gear clutch for full automatic washing machine realizing impeller and the washing of interior bucket Double-directional rotary.
Background technology
At present, the effect of the speed-reducing clutch of pulsator washing machine is generally drive impeller to do reciprocating rotation after being slowed down by the Double-directional rotary of motor.Conventional speed-reducing clutch primarily of power shaft, output shaft, output sleeve, input axle sleeve, braked wheel, be arranged on braked wheel inside reducing gear and be arranged on the clutch components composition that power shaft puts.Wash operating mode time, require that output shaft low-speed bidirectional rotates repeatedly, output sleeve and braked wheel as a whole, reducing gear generally only plays simple decelerating effect, when braked wheel is braked, output sleeve is also braked, and drive motors bidirectional rotation can only drive the corresponding bidirectional rotation of output shaft.
Existing twisting speed-reducing clutch, its internal reduction mechanism does not change, only change clutch control mechanism, by routine list ratchet, single ratchet, change two ratchet into, two ratchet, when washing operating mode, braked wheel is tentatively unclamped (being just totally released during dehydration), drive motors bidirectional rotation, drive the corresponding bidirectional rotation of output shaft, output sleeve is not because being braked simultaneously, and the current reaction masterpiece corresponding rotation reciprocal to output shaft when rotating by output shaft, its corner is very little, and be subject to the change in resistance of clothing, rotating speed and the amplitude of oscillation of output sleeve change at any time, unstable.Though formed stranding phenomenon, but do not reach desirable clean result, and because of brake band and the operating mechanism of two ratchet be link, during washing, two ratchet does not allow to leave ratchet (just leaving during dehydration), therefore during washing, brake band is only and tentatively unclamps, be separated not thorough, add the friction and wear of brake band, improve the shaping to brake band and adjustment requirement.When dehydration condition, require output shaft and output sleeve integrally unidirectional High Rotation Speed, to reach the object of centrifugal dehydration.In order to change washing and the operating mode of dewatering, conventional speed-reducing clutch must be furnished with the complete clutch parts such as ratchet, ratchet, ratchet spring, brake spring, clutch axle sleeve, adjustment bolt, but itself not there is the function of automatic clutch conversion, must through the manipulation of outside traction electric machine, make brake spring generation clutch action, washing and the operating mode of dewatering could be changed, its electric-control system and clutch control system all more complicated, add wearing and tearing, increase the opening force of brake lever, directly affect the service life of associated components.
Twisting formula speed-reducing clutch after improvement, adopt the reducing gear of bi-directional drive, its reducing gear is the rotation that two turn on the contrary, speed is different by the rotation of motor being exported, thus drive that impeller is contrary with interior bucket travel direction, rotation that speed is different respectively, and then play clothing is carried out washing the effect of washing by rubbing with the hands.The speed-reducing clutch of existing washing machine bi-directional drive is generally adopt planet fixed shaft gear train drive mechanism, gear transmission structure and Oscillating Tooth Gear Reducer structure, because general gear drive noise when positive and negative twocouese transmission is large, and Oscillating Tooth Gear Reducer structure to obtain manufacturing cost higher, therefore, planet fixed shaft gear train drive mechanism is widely used.
Application number be 03239381.4 Chinese patent disclose a kind of automatic reduction clutch of washing machine, it is primarily of power shaft, output shaft, output sleeve, input axle sleeve, braked wheel and the Dual Drive gear mechanism composition being arranged on braked wheel inside, power shaft, output sleeve and output shaft are connected with Dual Drive gear mechanism respectively, between braked wheel and output sleeve parts, arrangement of clutch are housed.During washing operating mode, output shaft and output sleeve are mutually reverse, two-wayly drive in proportion, swing rotary repeatedly, and relative strength rubs pendulum with the hands.During dehydration condition, by the locking effect of arrangement of clutch, output shaft and output sleeve can be made automatically to combine, make the unidirectional continuous rotation of high speed, centrifugal dehydration simultaneously.
The speed-reducing clutch of above-mentioned employing planet fixed shaft gear train drive mechanism, complex structure, loss increases, and efficiency reduces, and the overall dimensions of speed-reducing clutch is difficult to reduce, and reduces the volume of outer barrel of washing machine, reduces the washing dehydration rated capacity of washing machine.
