Description
Grab skipping clutch driving unit of the present utility model relates to a kind of clutch driving unit, especially a kind of clutch driving unit of washing machine.
The clutch driving unit pattern of washing machine has two kinds at present, and a kind of is that motor separates with clutch, uses belt transmission, its clutch band reducing gear, and complex structure easily produces uneven and big noise; Another kind is that motor and clutch coaxial connect together, and directly drives, and its motor is a variable speed electric motors, particularly, and structure is simpler, is difficult for producing uneven and big noise.Back a kind of clutch driving unit is disclosed, it mainly includes the hollow dehydrating shaft at the shaft at center and cover shaft, the lower end of shaft connects a rotor, following fixed disk is fixed a motor stator, constitute motor with rotor, be with an arrangement of clutch in hollow dehydrating shaft lower end, its center locating piece is fixed on the hollow dehydrating shaft, be embedded with around this locating piece that an one side can swing up and down, the flange of another opposite side embeds the hollow clutch rack of the corresponding pit of locating piece, along flange is to have spring to support between the inboard, one side that moves up and down of rotating shaft and locating piece, the outside has shifting block to stretch out, contact with the controlling organization of stirring of stirring this arrangement of clutch, and this limit all has an outer tiltedly projection up and down, the fixed disk bottom is evenly distributed in the recess that cooperates with last oblique projection, the end basin of rotor is evenly distributed in projection, and the pit that forms between the projection cooperates with the declivity projection of clutch rack.This clutch driving unit is stirred the hollow clutch rack and is swung up and down by stirring controlling organization, when last pendulum cooperates a recess of oblique projection circumference uniform distribution bottom fixed disk it on to fix hollow dehydrating shaft not rotate, realize the laundry function, when the bottom makes its declivity projection cooperate with the pit of the end basin circumference uniform distribution of rotor to drive simultaneously hollow dehydrating shaft to rotate, realize dehydrating function.Because this structure is complicated, make and install all inconveniences, and the spring in this arrangement of clutch is fragile, and clutch is out of order.
The purpose of this utility model provides a kind of simple in structure, and manufacturing and installation are all very convenient, the not troublesome grab skipping clutch driving unit of clutch.
Grab skipping clutch driving unit of the present utility model includes the dehydrating shaft at the shaft at center and 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, and dehydrating shaft between have on rolling bearing and following rolling bearing, one oil sealing is arranged between loam cake and the dehydrating shaft, the lower end of shaft connects a rotor, fix a motor stator below the lower house, constitute motor with rotor, lower house the inner is fixed with positioning seat, the lower end of dehydrating shaft is fixed with a rotating disk with nut, fix a rotating T shape with short pin on the rotating disk and dial hook, a pin is fixed on its next door, be equipped with one between the hook pin dialling of pin and group gib head portion and dial the hook spring, fixing sheave of suit on the shaft between dehydration axle head and the rotor center flange, can just reach the hook groove with one side hook of dialling hook cooperates, jagged on described positioning seat edge, but T shape is dialled this breach of another side hook left-hand thread of hook, and group hook pin stretches out the end and contacts with group plate and the ratchet of dialling the hook control lever under different conditions.
Described sheave is that key connects with being connected of shaft.
The neighboring of described sheave has uniform notch.
Described dehydrating shaft is that polygonal axis hole connects with being connected of rotating disk.
It is that key connects that described dehydrating shaft is connected with the another kind of rotating disk.
Described dehydrating shaft is to lack circular axis hole to connect with a kind of connection of also having of rotating disk.
The ratchet of described group of hook control lever be one by detent pin with the ratchet torsion spring be fixed on the control lever head can rotating bent plate.
When the tail end of control lever is subjected to the tractor tension, overcome the torsion spring torsion at control lever middle part, affect the plate of dialling of control lever head to stir hook pin, make to dial to be hooked in and dial in the uniform notch in the neighboring that buckles into sheave under the hook spring action, make dehydrating shaft by sheave, dial hook, and rotating disk be associated in rotor, thereby rotor drives shaft and dehydrating shaft rotates together, enters dewatering state; When the tail end of control lever is subjected to the tractor release action, the torsion spring at control lever middle part is replied torsion resets control lever, the ratchet of control lever head end is stirred hook pin, make in the breach of dialling hook disengaging sheave and anti-hook positioning seat limit, make rotating disk and rotor break away from and prevent that dehydrating shaft from rotating, rotor only drives shaft and rotates, and enters the washing state; This grab skipping clutch driving unit is owing to the hook groove mode clutch of taking to use always, simple in structure, manufacturing and installation are all very convenient, clutch is easy break-down not, and after control lever resetted when running into dead electricity or abnormal conditions under the high speed dewatering state, the activity of ratchet had been avoided running into because of the rotation of rotating disk inertia and has been dialled the parts that hook pin causes and damage.
Below in conjunction with accompanying drawing grab skipping clutch driving unit of the present utility model is described in more detail.
Fig. 1 is the structure cutaway view of grab skipping clutch driving unit of the present utility model.
Fig. 2 is that group fastener of grab skipping clutch driving unit of the present utility model is gone into the structural representation under the positioning seat state.
