The 3rd spline structure 421 that the heart covers 13 one end is identical.Drive shaft 3 from top to bottom successively with upper centre tooth 47, lower center
Tooth 413, lower planetary gear axes sleeve 13, second bearing 10 are connected.
The work process of this speed-reducing clutch is described below in detail.
When washing operating mode:
Solenoid 6 is energized, and produces electromagnetic force, and drive arrangement of clutch 7 is axially downward, and brake spring 8 is pressed
Contracting, arrangement of clutch 7 be sucked down in lower clutch tooth 11 thus with lower clutch tooth 11 and bottom end cover 2 formed one whole
Body.Now, the outside spline of the first spline structure 16 of lower clutch tooth 11 setting protruding upward and arrangement of clutch 7 upper end
Structure 73 matches clamping, the 3rd flower of the inner side spline structure 74 of arrangement of clutch 7 upper end and lower planetary gear axes sleeve 13
Bond structure 421 matches clamping, and arrangement of clutch 7 is braked, and second spline structure 121 at drive shaft 3 middle part is located at clutch
The centre of spline structure 74 inside the upper and lower ends of device 7, the state being an off between drive shaft 3 and arrangement of clutch 7,
The dentation projective structure 417 of braked wheel lower cover 42 bottom is separated with arrangement of clutch 7, and braked wheel 4 is in the shape being totally released
State.
Driving motor drives that drive shaft 3 is two-way repeatedly rotates, and drive shaft 3 drives lower centre tooth 413 to rotate, lower centre tooth
413 four lower planetary gears 44 of drive rotate, and four lower planetary gears 44 drive the lower planetary gear external toothing 43 of outer ring to rotate,
Now the rotation direction of the rotation direction of lower planetary gear external toothing 43 and drive shaft 3 is conversely, because lower planetary gear external toothing
43 rotate to drive and cover 41 on braked wheel lower cover 42 and braked wheel with braked wheel lower cover 42 close-fitting, lower planetary gear external toothing 43
Rotate, the first output shaft 14 that braked wheel covers 41 upper ends is rotated with the direction contrary with drive shaft 3, the first output shaft
14 are connected with inner tank of washing machine, and then drive inner tank of washing machine rotation.
Meanwhile, drive shaft 3 drives upper centre tooth 47 to rotate, and upper centre tooth 47 drives five upper planet wheels 49 to rotate, by
The 3rd spline structure 421 in lower planetary gear axes sleeve 13 is fixed it is impossible to rotate by arrangement of clutch 7 clamping, tight with it
The lower planetary gear lower cover 412 joined also is braked, by the effect of lower planet axle 414 so that lower planetary gear upper cover plate
411 are also braked, then due to lower planetary gear upper cover plate 411 with upper planet wheel external toothing 410 close-fitting so that upper planet wheel
External toothing 410 can not rotate, and five upper planet wheels 49 are engaged with fixed upper planet wheel external toothing 410, make five
Individual upper planet wheel 49 together rotates together with upper planet wheel upper cover plate 45, upper planet wheel lower cover 46, now, upper planet
The rotation direction of wheel upper cover plate 45 is identical with the rotation direction of drive shaft, and second on upper planet wheel upper cover plate 45 is defeated
Shaft 15 is to rotate with drive shaft 3 identical direction, and then drives agitation wheel for washing machine rotation.
By upper centre tooth 47, lower centre tooth 413, upper planet wheel 49, lower planetary gear 44, upper planet wheel external toothing 410
And the deceleration of lower planetary gear external toothing 43, so that the first output shaft 14 and the second output shaft 15 is back-driven into simultaneously, enter
And drive inner core and impeller to rotate in the opposite direction respectively, formed and turn to the contrary and certain power output of gear ratio,
Complete the washing procedure of Dual Drive high-effectly.
When dehydration condition:
Solenoid 6 power-off, brake spring 8 is isolated arrangement of clutch 7 under reset force effect from lower clutch tooth 11
Come, simultaneously the outside spline structure 73 of arrangement of clutch 7 upper end and the dentation projective structure 417 of braked wheel lower cover 42 bottom
Mutually clamping forms an entirety, second spline structure 121 at drive shaft 3 middle part and the inner side flower of arrangement of clutch 7 lower end
Bond structure 74 matches clamping, and drive shaft 3 and arrangement of clutch 7 also form an entirety, now, braked wheel 4 and drive shaft
3 are braked completely by arrangement of clutch 7, are automatically integrated into a whole with arrangement of clutch 7.The of lower planetary gear axes sleeve 13
Three spline structures 421 are located at the centre of spline structure 74 inside the upper and lower ends of arrangement of clutch 7, lower planetary gear axes sleeve
The state being an off between 13 and arrangement of clutch 7.
Driving motor drives drive shaft 3 one direction continuously to rotate on demand, under the braking action of arrangement of clutch 7, braking
On the braked wheel lower cover 42 of wheel 4 and braked wheel, lid 41 and drive shaft 3, at the same speed with turning to rotation, braked wheel cover 41 upper ends
The first output shaft 14 and drive shaft 3 at the same speed with turning to rotation, and then drive inner tank of washing machine rotation.
Due to braked wheel lower cover 42 and the mutual close-fitting of lower planetary gear external toothing 43, braked wheel lower cover 42 while rotation,
Lower planetary gear external toothing 43 also rotates, and the steering of lower planetary gear external toothing 43 is identical with the steering of drive shaft 3, and now,
Due to the rotation of drive shaft 3, lower centre tooth 413 also passive rotation, due to lower planetary gear external toothing 43 and lower centre tooth
413 steering is identical, and four lower planetary gears 44 are equivalent to and are braked and can not rotate around lower planet axle 414, but band
Dynamic lower planetary gear lower cover 412 and lower planetary gear upper cover plate 411 are rotated jointly with being turned to drive shaft 3 identical, then by
In lower planetary gear upper cover plate 411 with upper planet wheel external toothing 410 close-fitting so that upper planet wheel external toothing 410 similarly with
Turn to rotation with drive shaft 3 identical, because the rotation of drive shaft 3 drives upper centre tooth 47 to rotate, outside upper planet wheel
Gear ring 410 is identical with the steering of upper centre tooth 47, and five upper planet wheels 49 are equivalent to and are braked, and then drives upper planet
Wheel upper cover plate 45, upper planet wheel lower cover 46 are rotated jointly with being turned to drive shaft 3 identical, now, in upper planet
The second output shaft 15 on wheel upper cover plate 45 is to rotate with drive shaft 3 identical direction, and then drives agitation wheel for washing machine rotation
Turn.
In dehydration, impeller is identical with the direction of rotation of inner core, due to upper planet wheel 49 and lower planetary gear 44 here
During by relative brake, there is not the situation of deceleration, lower planetary gear external toothing 43, lower planetary gear lower cover 412,
Lower planetary gear upper cover plate 411, upper planet wheel external toothing 410, upper planet wheel upper cover plate 45, upper planet wheel lower cover 46
All rotate at a same speed, and identical with the steering of drive shaft 3, rotating speed is also identical, makes the first output shaft 14 and
Two output shafts 15 operate in the same direction at the same speed, complete centrifuge dehydration program.
As described above, combining the plan content given by accompanying drawing, similar technical scheme can be derived.In every case it is
Without departing from the content of technical solution of the present invention, any letter above example made according to the technical spirit of the present invention
Single modification, equivalent variations and modification, all still fall within the range of technical solution of the present invention.
