That all that the periphery, original arrangement of clutch can be individually occupied of deceleration device is arranged in arrangement of clutch of the present invention
Part axial space saves, and reduces the whole height of speed-reducing clutch, so as in the case where washing capacity is constant
Reduce the volume of washing machine, or increases washing capacity in the case where washing machine constancy of volume.In the research and development of washing machine, wash
Even if wash the axial space that bucket/cylinder bottom speed-reducing clutch occupies subtract be reduced by several millimeters it is all very big at last improve, washing is held
The influence of amount will be very big, and the axial length of general clutch axle sleeve can reach tens millimeters, and the present invention puts clutch axle sleeve
To the outside of the reduction gearing of deceleration device, the axial length of clutch axle sleeve is saved, washing capacity is had greatly
It improves.
And clutch axle sleeve of the ring gear 4 of speed-reducing clutch of the present invention as arrangement of clutch, eliminate individual clutch shaft
Set, reduces the quantity of part, and structure is simple, easy to assembly, saves cost.
Input shaft 1 is connect with direct driving motor, and the deceleration device is at least partially disposed in the cavity of direct driving motor stator 7
Interior, the gear parts of the preferably described deceleration device are arranged in the cavity of direct driving motor stator 7.
One shell 19 is set outside ring gear 4, and shell 19 and washing machine outer cylinder are relatively fixed, and part is arranged in direct driving motor
In the cavity of stator 7, the preferably described shell 19 includes a upper cover, which is fixedly connected with washing machine outer cylinder, it is preferably described on
Lid is the mounting plate 8 of speed-reducing clutch.
The both ends of ring gear 4 are respectively equipped with end-tooth 5, and ring gear 4 is axially movable at least in first position and second
Position, when the state of first position, the end-tooth 5 of 4 one end of ring gear is connect with a rotational structure, and ring gear 4 and rotor 6 are same in the same direction
Speed rotation, this state is dewatering state, and when the second position, the end-tooth 5 of 4 other end of ring gear is connect with a fixed structure, interior
Gear ring 4 is fixed, this state is washing state.Or can also have the third place, when the third place state, 4 both ends of ring gear
End-tooth 5 is not connect with other structures, and the ring gear 4 is in free state, this state is generally also washing state.
The rotational structure is the rotor 6 of direct driving motor or is and the relatively-stationary clutch discs 23 of rotor 6, the fixation
Structure is outer cylinder or shell 19 or is to be arranged in deceleration device with the relatively-stationary fixed disk of shell 19, the fixed disk for output
One end that axis is pierced by.
The mounting plate 8 of speed-reducing clutch is equipped with tooth socket 9 corresponding with the end-tooth 5 of ring gear 4, the ring gear 4
End-tooth 5 protrude into corresponding tooth socket 9, mounting plate 8 and ring gear 4 are directly connected to, this kind of connection type, and structure is simple, assembly
Simply, components are less, save the cost；Or on the mounting plate 8 of the speed-reducing clutch fixed disk is set (fixed disk is being schemed
In be not shown), the fixed disk be equipped with tooth socket 9 corresponding with the end-tooth 5 of ring gear 4, the end-tooth of the ring gear 4
5 protrude into corresponding tooth socket 9, and mounting plate 8 and ring gear 4 are indirectly connected with, this kind of connection type is more advantageous to the use longevity of mounting plate
Life, if ring gear 4 is directly connected to by the tooth socket 9 on end-tooth 5 and mounting plate 8, since torque is larger in rotation process, tooth socket
After 9 damages, entire mounting plate need to all be replaced, if being connected by the tooth socket 9 in fixed disk, the tooth socket 9 in fixed disk is damaged
After bad, only replacement fixed disk, the maintenance of such washing machine in the future it can become more convenient.
The rotor 6 of direct driving motor is equipped with tooth socket 9 corresponding with the end-tooth 5 of ring gear 4, the end of the ring gear 4
Face tooth 5 protrudes into corresponding tooth socket 9, and rotor 6 and ring gear 4 are directly connected to, this kind of connection type, and structure is simple, assembly is simple, and zero
Component is less, save the cost；Or rotor 6 is connect by a clutch discs 23 with ring gear 4, the clutch discs 23 and rotor 6 are solid
The fixed or described clutch discs 23 are fixed with input shaft 1, and the clutch discs 23 are equipped with corresponding with the end-tooth 5 of ring gear 4
Tooth socket 9, the end-tooth 5 of the ring gear 4 protrude into corresponding tooth socket 9, and rotor 6 and ring gear 4 are indirectly connected with, this kind of connection type
Better protective effect is played to rotor, due to dehydration when rotor high speed rotation, torque is larger, on rotor 6 fluting can to turn
The intensity of son 6 affects, so having to increase the thickness of rotor 6, will cause the increase of the increasing additive weight of cost, so
It is indirectly connected with by clutch discs 23 as preferred embodiment, it is further preferred that clutch discs 23 are fixedly connected with the rotor, can
It is connected by way of interference fit or spline connection.
Deceleration device includes central gear 10, and the planetary gear 11 engaged with central gear 10 is engaged with planetary gear 11
Ring gear 4, the rotor 6 of 1 one end of input shaft of the speed-reducing clutch and direct driving motor connects, the other end and central gear 10
Connection, 2 one end of output shaft of the speed-reducing clutch connect the other end with central gear 10 and connect with agitation wheel for washing machine, described to subtract
3 one end of output sleeve of speed clutch connect the other end with planetary gear pinion frame 12 and connect with washing of drum type washing machine cylinder；
The arrangement of clutch includes the ring gear 4 of deceleration device and the driving device of driving ring gear axial movement.Since ring gear 4 is made
For clutch axle sleeve, output sleeve 3 is driven so preferably connecting not by ring gear 4 with output sleeve 3.
Above-mentioned input shaft 1 and output shaft 2 can be two axis, connect respectively with central gear or above-mentioned input shaft 1 and
Output shaft 2 is one coaxial, and currently preferred is input shaft 1 and output shaft 2 is one coaxial, such 1 He of situation input shaft
The support of two bearings of output shaft 2 needs, further shortens the axial length of speed-reducing clutch.
First bearing 13,19 other end of shell and input shaft 1 are set between described 19 one end of shell and output sleeve 3
Between second bearing 14 is set, the deceleration device is arranged between first bearing 13 and second bearing 14, and first bearing 13,
