Abstract
The utility model relates to a clutch for a scrubbing type washing machine without braking. The utility model relates to a speed reducing clutch with a planetary wheel, a stirring and washing shaft 1, and a hollow dewatering shaft 3. The utility model is not provided with a braking band, and the dewatering shaft is in a free state. In addition, an engaging and disengaging mechanism with inverse double ratchet wheels, which is controlled by a push rod in single travel, is arranged. An engaging and disengaging spring 26 is connected with each ratchet wheel 24, and the double ratchet wheels inversely rotate to make the spring inversely opened and closed to control the connection of an input shaft 16 of the clutch and an output sleeve 25 of the clutch and to control washing and dewatering. At the time of the washing, a stirring wheel and a dewatering barrel simultaneously rotate for reinforcing the rotation of water flow and obtaining sufficient washing power.
Description
Brakeless scrubbing type washing machine clutch of the present utility model relates to a kind of driving clutch of washing machine.
Washing machine commonly used at present drives clutch and comprises deceleration device and brake apparatus and clutch, clutch adopts single ratchet clutch or spring clutch to control the clutch switching that washing shaft is connected with dehydrating shaft, realize dehydration and laundry function, but because their speed-reducing clutch is to control washing shaft and dehydrating shaft respectively, promptly when laundry, have only washing shaft band stirring wheel to change, the driving clutch is failure to actuate, make dehydrating shaft and dehydration barrel firmly motionless because of the brake apparatus braking, drive clutch operating during dehydration, washing shaft was connected with dehydrating shaft when brake apparatus was unclamped, washing shaft and dehydrating shaft one run up, like this owing to dehydrating shaft and dehydration barrel when doing washing are motionless, the current that are used to wash can only lean on the rotation of stirring wheel to produce, thereby can not obtain sufficient washing force, are difficult for cleaning clothes.
The purpose of this utility model provides a kind of simple in structure, makes and installs all very easily, can obtain the fully brakeless scrubbing type washing machine clutch of washing.
Brakeless scrubbing type washing machine clutch of the present utility model, include at the shaft at center and the hollow dehydrating shaft of cover shaft, an oiliness bearing is respectively arranged up and down between them, there are a loam cake and lower house to connect together in its periphery, one sealing device is arranged between loam cake and the dehydrating shaft, lower house includes planetary gear speed reducing mechanism, with the braking hub and the ratchet clutch that wrap in the planetary gear speed reducing mechanism outside, the lower end of shaft connects the planetary gear speed reducing mechanism output, planetary gear speed reducing mechanism input lace wheel, the dehydrating shaft lower end links to each other with braking hub upper end, braking hub lower end is enclosed within the outer output cover of power shaft with the planetary gear speed reducing mechanism other end and links to each other, between this output cover and the power shaft oiliness bearing is arranged respectively up and down, whole connector outside also respectively has a roller bearings up and down, the ratchet mechanism of this planetary gear speed-reducing clutch ratchet clutch is an oppositely two ratchet mechanism, oppositely be connected with a clutch spring in two ratchets of installing, two ratchet backward rotation make the reverse folding of clutch spring, the clutch spring is unclamped simultaneously or hold planetary gear speed-reducing clutch output cover tightly and the shaft coupling that overlaps near this output on planetary gear speed-reducing clutch power shaft, make it to be subjected to simultaneously clutch for clutch control, brakeless band on the described braking hub, braking hub and dehydrating shaft are free state when static and washing, action had a stroke when push rod that is spurred by the washing machine tractor was only deposited dehydration, the fork that is connected with push rod is the C font, on have one to regulate the adjustment screw of push rod stroke and the ratchet of two staggered positions.
The end of described shaft coupling on planetary gear speed-reducing clutch power shaft, this end profiles matches with the interior hole shape of shaft coupling and cooperates closely.
Brakeless scrubbing type washing machine clutch of the present utility model is owing to adopt the oppositely two ratchet mechanisms of planetary gear speed-reducing clutch, ratchet is pushed down two ratchets of reverse installation under the normality, the clutch spring reverse opening that connects in two ratchets, make the clutch spring unclamp the connection of the planetary gear speed-reducing clutch being exported cover and the shaft coupling on planetary gear speed-reducing clutch power shaft simultaneously, simultaneously because brake band is in the past cancelled, brakeless band on the braking hub, under the normality and the laundry state down braking hub and dehydrating shaft are free state, when motor drives agitator treating axle is done washing, the current of washing lean on the rotation of the stirring wheel that links to each other with wash shaft to produce and drive dehydration barrel and rotate, the rotation of current is strengthened, thereby obtained sufficient washing force; Push rod moves has only a stroke, be failure to actuate when depositing laundry, tractor drives the push rod action when entering dewatering state, ratchet leaves two ratchets immediately, the trip is regulated suitably by adjustment screw, two ratchets make the clutch spring hold shaft coupling and planetary gear speed-reducing clutch output cover simultaneously tightly in clutch spring action turning down, make motor drives washing power shaft drive output cover and hollow dehydrating shaft one by this clutch spring, when cooperating, should make it in dewatering state, can not open bung, just can open bung during to be drained off barrel of stall with washing machine; This structure is owing to cancelled braking, and the braking hub need not made special thermal treatment, and simple in structure, makes and installs all very easily.
Below in conjunction with accompanying drawing brakeless scrubbing type washing machine clutch of the present utility model is described in more detail.
