As shown in Figure 18 and Figure 19, the second bearing 10 is installed in the fastening of opening part bottom bottom end cover 2, and drive shaft 3 is through the
Two bearings 10 stretch to enclosure interior.Drive shaft 3 central structure is the second spline structure 121, with lower planetary gear axes sleeve 13 1
3rd spline structure 421 of end is identical.Drive shaft 3 the most successively with upper centre tooth 47, lower centre tooth 413, lower planetary gear
Axes sleeve the 13, second bearing 10 is 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, drives arrangement of clutch 7 axially downward, and brake spring 8 is compressed,
Arrangement of clutch 7 is sucked down in lower clutch tooth 11 thus forms an entirety with lower clutch tooth 11 and bottom end cover 2.Now,
First spline structure 16 of lower clutch tooth 11 setting protruding upward and the outside spline structure 73 of arrangement of clutch 7 upper end match card
Tightly, the 3rd spline structure 421 of the inner side spline structure of arrangement of clutch 7 upper end 74 and lower planetary gear axes sleeve 13 matches clamping,
Arrangement of clutch 7 is braked, and the second spline structure 121 in the middle part of drive shaft 3 is positioned at spline knot inside the two ends up and down of arrangement of clutch 7
The centre of structure 74, the state being an off between drive shaft 3 and arrangement of clutch 7, the dentation projective structure bottom braked wheel lower cover 42
417 separate with arrangement of clutch 7, and braked wheel 4 is in the state being totally released.
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 drive four lower planetary gears 44 to rotate, and four lower planetary gears 44 drive the lower planetary gear external toothing 43 of outer ring to rotate, and this is at present
The rotation direction of the rotation direction of planetary gear external toothing 43 and drive shaft 3 is conversely, because lower planetary gear external toothing 43 and braked wheel
Lower cover 42 close-fitting, lower planetary gear external toothing 43 rotates and drives braked wheel lower cover 42 and braked wheel upper cover 41 to rotate, braked wheel upper cover
First output shaft 14 of 41 upper ends rotates with the direction contrary with drive shaft 3, and the first output shaft 14 is connected with inner tank of washing machine, enters
And drive inner tank of washing machine to rotate.
Meanwhile, drive shaft 3 drives upper centre tooth 47 to rotate, and upper centre tooth 47 drives five upper planet wheels 49 to rotate, due to
3rd spline structure 421 of lower planetary gear axes sleeve 13 is fastened by arrangement of clutch 7 card, it is impossible to rotate, descending with its close-fitting
Star-wheel lower cover 412 is also braked, by the effect of lower planet axle 414 so that lower planetary gear upper cover plate 411 is also braked, then
Due to lower planetary gear upper cover plate 411 and upper planet wheel external toothing 410 close-fitting so that upper planet wheel external toothing 410 can not rotate, five
Individual upper planet wheel 49 engages with fixed upper planet wheel external toothing 410, makes five upper planet wheels 49 together with on upper planet wheel
Cover plate 45, upper planet wheel lower cover 46 together rotate, now, and the rotation direction of upper planet wheel upper cover plate 45 and the rotation of drive shaft
Direction is identical, and the second output shaft 15 on upper planet wheel upper cover plate 45 rotates with the direction identical with drive shaft 3, and then drives
Agitation wheel for washing machine rotates.
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, makes the first output shaft 14 and the second output shaft 15 be back-driven into simultaneously, and then carries respectively
Dynamic inner core and impeller rotate in the opposite direction, are formed and turn to contrary and that gear ratio is certain power output, complete double high-effectly
The washing procedure driven.
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
Coming, the dentation projective structure 417 bottom the outside spline structure 73 of arrangement of clutch 7 upper end and braked wheel lower cover 42 mutually blocks simultaneously
Tight form an entirety, inner side spline structure 74 phase of the second spline structure 121 in the middle part of drive shaft 3 and arrangement of clutch 7 lower end
Joining clamping, drive shaft 3 and arrangement of clutch 7 also form an entirety, and now, braked wheel 4 and drive shaft 3 are complete by arrangement of clutch 7
Braking, is integrated into a whole automatically with arrangement of clutch 7.3rd spline structure 421 of lower planetary gear axes sleeve 13 is positioned at clutch
The centre of spline structure 74, the shape being an off between lower planetary gear axes sleeve 13 and arrangement of clutch 7 inside the two ends up and down of device 7
State.
Driving motor drives drive shaft 3 one direction to rotate continuously on demand, under the braking action of arrangement of clutch 7, and braking
The braked wheel lower cover 42 of wheel 4 and braked wheel upper cover 41 are synchronized with drive shaft 3 with turning to rotation, the first of braked wheel upper cover 41 upper end
Output shaft 14 is synchronized with drive shaft 3 with turning to rotation, and then drives inner tank of washing machine to rotate.
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 turning to of lower planetary gear external toothing 43 is identical with turning to of drive shaft 3, and now, due to
The rotation of drive shaft 3, lower centre tooth 413 also passive rotation, turn to phase due to lower planetary gear external toothing 43 and lower centre tooth 413
With, four lower planetary gears 44 are equivalent to be braked and can not rotate around lower planet axle 414, but drive lower planetary gear lower cover
412 turn to common rotation with lower planetary gear upper cover plate 411 with identical with drive shaft 3, 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 turns to rotation with identical with drive shaft 3 too, by
Rotation in drive shaft 3 drives upper centre tooth 47 to rotate, and upper planet wheel external toothing 410 is identical with turning to of upper centre tooth 47, and five
Individual upper planet wheel 49 is equivalent to be braked, so drive upper planet wheel upper cover plate 45, upper planet wheel lower cover 46 with drive shaft 3
Identical turns to common rotation, and now, the second output shaft 15 on upper planet wheel upper cover plate 45 is with the side identical with drive shaft 3
To rotation, and then agitation wheel for washing machine is driven to rotate.
In dehydration, impeller is identical with the direction of rotation of inner core, owing to upper planet wheel 49 and lower planetary gear 44 are at this
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 revolve the most at a same speed
Turn, and identical with turning to of drive shaft 3, rotating speed is the most identical, makes the first output shaft 14 and the second the most synchronized operating of output shaft 15,
Complete centrifuge dehydration program.
As it has been described above, combine the plan content given by accompanying drawing, similar technical scheme can be derived.In every case it is not take off
From the content of technical solution of the present invention, any simple modification of above example being made according to the technical spirit of the present invention, etc.
With change and modification, all still fall within the range of technical solution of the present invention.
