The course of work 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 to move down vertically, brake spring 8 is compressed, and arrangement of clutch 7 to be inhaled into downwards in lower clutch tooth 11 thus to form 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 matches with the outside spline structure 73 of arrangement of clutch 7 upper end and clamps, the inner side spline structure 74 of arrangement of clutch 7 upper end matches with the 3rd spline structure 421 of lower planetary gear axes sleeve 13 and clamps, arrangement of clutch 7 is braked, the centre of spline structure 74 inside the two ends up and down that the second spline structure 121 in the middle part of driving shaft 3 is positioned at arrangement of clutch 7, it is the state departed between driving shaft 3 and arrangement of clutch 7, dentation projective structure 417 bottom braked wheel lower cover 42 is separated with arrangement of clutch 7, braked wheel 4 is in the state be totally released.
Driving motor drives that driving shaft 3 is two-way repeatedly rotates, driving shaft 3 drives lower centre tooth 413 to rotate, lower centre tooth 413 drives four lower planetary gears 44 to rotate, four lower planetary gears 44 drive the lower planetary gear external toothing 43 of outer ring to rotate, now the rotation direction of lower planetary gear external toothing 43 is contrary with the rotation direction of driving shaft 3, due to 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, first output shaft 14 of braked wheel upper cover 41 upper end rotates with the direction contrary with driving shaft 3, first output shaft 14 is connected with inner tank of washing machine, and then drive inner tank of washing machine to rotate.
Simultaneously, driving shaft 3 drives upper centre tooth 47 to rotate, upper centre tooth 47 drives five upper planet wheels 49 to rotate, because the 3rd spline structure 421 of lower planetary gear axes sleeve 13 is clamped fixing by arrangement of clutch 7, can not rotate, also be braked with the lower planetary gear lower cover 412 of its close-fitting, by the effect of lower planet axle 414, lower planetary gear upper cover plate 411 is also braked, again due to lower planetary gear upper cover plate 411 and upper planet wheel external toothing 410 close-fitting, upper planet wheel external toothing 410 can not be rotated, five upper planet wheels 49 engage with fixed upper planet wheel external toothing 410, make five upper planet wheels 49 together with upper planet wheel upper cover plate 45, upper planet wheel lower cover 46 together rotates, now, the rotation direction of upper planet wheel upper cover plate 45 is identical with the rotation direction of driving shaft, the second output shaft 15 on upper planet wheel upper cover plate 45 rotates with the direction identical with driving shaft 3, and then drive agitation wheel for washing machine to rotate.
By the deceleration of upper centre tooth 47, lower centre tooth 413, upper planet wheel 49, lower planetary gear 44, upper planet wheel external toothing 410 and lower planetary gear external toothing 43, make the first output shaft 14 and the second output shaft 15 be reversed driving simultaneously, and then drive inner core and impeller to rotate in the opposite direction respectively, formed and turn to contrary and that gearratio is certain Power output, complete the washing procedure of Dual Drive high-effectly.
When dehydration condition:
Solenoid 6 power-off, brake spring 8 is separated arrangement of clutch 7 under reset force effect from lower clutch tooth 11, the outside spline structure 73 of arrangement of clutch 7 upper end clamps formation entirety mutually with the dentation projective structure 417 bottom braked wheel lower cover 42 simultaneously, the second spline structure 121 in the middle part of driving shaft 3 matches with the inner side spline structure 74 of arrangement of clutch 7 lower end and clamps, driving shaft 3 and arrangement of clutch 7 also form an entirety, now, braked wheel 4 and driving shaft 3 are braked completely by arrangement of clutch 7, with arrangement of clutch 7 automatically in conjunction with as a whole.Inside the two ends up and down that 3rd spline structure 421 of lower planetary gear axes sleeve 13 is positioned at arrangement of clutch 7, the centre of spline structure 74, is the state departed between lower planetary gear axes sleeve 13 and arrangement of clutch 7.
Driving motor drives driving shaft 3 one direction continuous rotation on demand, under the braking action of arrangement of clutch 7, the braked wheel lower cover 42 of braked wheel 4 and braked wheel upper cover 41 turn to rotation together with driving shaft 3 is synchronized, first output shaft 14 of braked wheel upper cover 41 upper end is synchronized with turning to rotation with driving shaft 3, and then drives inner tank of washing machine to rotate.
Due to braked wheel lower cover 42 and lower planetary gear external toothing 43 close-fitting mutually, braked wheel lower cover 42 is while rotation, lower planetary gear external toothing 43 also rotates, turning to of lower planetary gear external toothing 43 is identical with turning to of driving shaft 3, and now, due to the rotation of driving shaft 3, lower centre tooth 413 also passive rotation, because turning to of lower planetary gear external toothing 43 and lower centre tooth 413 is identical, 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 to turn to common rotation with lower planetary gear upper cover plate 411 with identical with driving shaft 3, again due to lower planetary gear upper cover plate 411 and upper planet wheel external toothing 410 close-fitting, upper planet wheel external toothing 410 is made to turn to rotation with identical with driving shaft 3 too, rotation due to driving shaft 3 drives upper heart tooth 47 to rotate, upper planet wheel external toothing 410 is identical with turning to of upper centre tooth 47, five upper planet wheels 49 are equivalent to be braked, and then drive upper planet wheel upper cover plate 45, upper planet wheel lower cover 46 turns to common rotation with identical with driving shaft 3, now, the second output shaft 15 on upper planet wheel upper cover plate 45 rotates with the direction identical with driving shaft 3, and then drive agitation wheel for washing machine to rotate.
In dehydration, impeller is identical with the direction of rotation of inner core, because upper planet wheel 49 and lower planetary gear 44 are in the process 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 with same speed, and it is identical with turning to of driving shaft 3, rotating speed is also identical, make the first output shaft 14 and the synchronized in the same way running of the second output shaft 15, complete centrifugal dehydration program.
As mentioned above, plan content given by reference to the accompanying drawings, can derive similar technical scheme.In every case be the content not departing from technical solution of the present invention, any simple modification done above embodiment according to technical spirit of the present invention, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
