Describe the course of work of this speed-reducing clutch below in detail.
When washing operating mode:
Solenoid 6 energising, produces electromagnetic force, drives arrangement of clutch 7 to move down vertically, and brake spring 8 is compressed, thereby arrangement of clutch 7 is inhaled into downwards in lower clutch tooth 11 and forms an integral body with lower clutch tooth 11 and bottom end cover 2.Now, the first spline structure 16 of lower clutch tooth 11 settings protruding upward and the outside spline structure 73 of the arrangement of clutch 7 upper ends clamping that matches, the inner side spline structure 74 of arrangement of clutch 7 upper ends and the 3rd spline structure 421 of lower planetary gear axes sleeve 13 clamping that matches, arrangement of clutch 7 is braked, second spline structure 121 at driving shaft 3 middle parts is positioned at the centre of spline structure 74 inside the two ends up and down of arrangement of clutch 7, it between driving shaft 3 and arrangement of clutch 7, is the state departing from, the dentation projective structure 417 of braked wheel lower cover 42 bottoms is separated with arrangement of clutch 7, the state of braked wheel 4 in being totally released.
Driving motor drives the two-way rotation repeatedly of driving shaft 3, 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, the direction of rotation of the rotation direction of lower planetary gear external toothing 43 and driving shaft 3 now, due to lower planetary gear external toothing 43 and braked wheel lower cover 42 close-fittings, lower planetary gear external toothing 43 rotates and drives braked wheel lower cover 42 and braked wheel upper cover 41 to rotate, the first output shaft 14 of braked wheel upper cover 41 upper ends is with the direction rotation contrary with driving shaft 3, the 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 fixing by arrangement of clutch 7 clampings, 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-fittings, upper planet wheel external toothing 410 can not be rotated, five upper planet wheels 49 mesh 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 is with the direction rotation 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 respectively inner core and impeller to rotate by opposite direction, form the certain power output of switched in opposite and gearratio, complete two washing procedures that drive high-effectly.
When dehydration condition:
Driving motor drives driving shaft 3 one direction continuous rotations 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 are synchronized with turning to rotation with driving shaft 3, the first output shaft 14 of braked wheel upper cover 41 upper ends is synchronized with turning to rotation with driving shaft 3, and then drives 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 is in 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, rotation due to driving shaft 3, lower centre tooth 413 is passive rotation also, 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 and lower planetary gear upper cover plate 411 with the turn to common rotation identical with driving shaft 3, again due to lower planetary gear upper cover plate 411 and upper planet wheel external toothing 410 close-fittings, make upper planet wheel external toothing 410 too with the turn to rotation identical with driving shaft 3, because the upper centre tooth 47 of rotation drive of driving shaft 3 is rotated, 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 is with the turn to common rotation identical with driving shaft 3, now, the second output shaft 15 on upper planet wheel upper cover plate 45 is with the direction rotation 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 is braked by relative in this process with lower planetary gear 44, 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 are all with same speed rotation, and 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, given scheme content, can derive similar technical scheme by reference to the accompanying drawings.In every case be the content that does not depart from technical solutions of the utility model, any simple modification, equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
