Description
(1) technical field
The utility model relates to a kind of speed-reducing clutch.
(2) background technology
Core component in the two-power washing machine is two speed-reducing clutchs that drive, and presses opposite spin by two driving speed-reducing clutchs drive washing machine inner tubs and impeller.It is very complicated that but two in the existing two-power washing machine drive the speed-reducing clutch structures, and inside needs the multiple sets of teeth wheel to mesh, and not only causes bulkyly, and too much cooperation easily produces mechanical breakdown.
(3) summary of the invention
In order to overcome in the prior art two deficiencies that speed-reducing clutch complex structures, volume more greatly, easily produce fault that drive, the utility model provides that a kind of clutch configuration is simple, volume is less, the two speed-reducing clutchs that drive of stable and reliable operation.
The technical scheme in the invention for solving the technical problem is: a kind of two speed-reducing clutchs that drive, comprise the braking shell, be installed on flange clutch sleeve, input gear shaft, the interior axle of output of described braking shell front end and be placed in the outer dehydration sleeve of axle in the described output, described input gear bush is connected in the described flange clutch sleeve, and the head of the head of axle, dehydration sleeve all is connected with the afterbody of described input gear shaft by the gear train that is positioned at the braking shell in the output; The head of described input gear shaft stretches out outside the described flange clutch sleeve, the head of input gear shaft is set with clutch cover, the joint of described clutch cover and input gear shaft is equipped with belt wheel, the joint of described clutch cover and described flange clutch sleeve is arranged with the clutch spring, the described clutch spring ratchet outer with being sleeved on flange clutch sleeve is connected a described ratchet and a click-fit; Described braking shell is wrapped with clutch outer member, and described ratchet connects the clutch driving lever, and described clutch driving lever is connected with described clutch outer member by Brake torsion spring; The afterbody of described input gear shaft is first gear, gear train in the braking shell comprises described first gear, at least two planet duplicate gears, internal gear and external toothings, the back tooth of each planet duplicate gear and described first gears engaged, the nipper of each planet duplicate gear mesh with described internal gear and external toothing respectively; Interior of described output is connected with described internal gear, and the head cover and the described dehydration sleeve of described external toothing also are connected with it outward.
Preferably, the number of planet duplicate gear is three or two.
When washing machine washs, ratchet fastening ratchet, the clutch spring is in relaxed state, and is not fastening between clutch cover and the flange clutch sleeve, drives clutch cover and the rotation of input gear shaft by belt wheel.Each planet duplicate gear of first gear driven of its afterbody rotated when the input gear shaft rotated, duplicate gear drives external toothing again and internal gear rotates, drive axle rotation in the output by internal gear again, external toothing drives the dehydration sleeve and rotates, and the direction of rotation of interior axle of output and dehydration sleeve.Axle drives the impeller be attached thereto and rotates in the output, and the dehydration sleeve drives the interior bucket that is attached thereto and rotates, so impeller also is counter-rotation with interior bucket, the formation rotary water current.When dewatering, stir the clutch driving lever and make ratchet and ratchet break away from, clutch this moment spring is held clutch cover and flange clutch sleeve tightly, when belt wheel rotates except that clutch outer member unitary rotation, this moment, gear train no longer rotated, impeller is pressed same direction rotation with interior barrel.
The beneficial effects of the utility model are: clutch simple in structure, so stable and reliable operation, and volume is less, and impeller and interior bucket backward rotation form the current that roll during washing, help washing.
(4) description of drawings
Fig. 1 is complete section figure of the present utility model.
Fig. 2 is the figure that partly cuts open of the present utility model.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, Fig. 2, a kind of two speed-reducing clutch that drives, comprise braking shell 1, be installed on axle 4 in the flange clutch sleeve 2, input gear shaft 3, output of described braking shell 1 front end and be placed in the outer dehydration sleeve 5 of axle in the described output 4, described input gear shaft 3 is socketed in the described flange clutch sleeve 2, and the head of the head of axle 4, dehydration sleeve 5 all is connected with the afterbody of described input gear shaft 3 by the gear train that is positioned at braking shell 1 in the output.
The head of described input gear shaft 3 stretches out outside the described flange clutch sleeve 2, the head of input gear shaft 3 is set with clutch cover 6, the joint of described clutch cover 5 and input gear shaft 3 is equipped with belt wheel 18, described clutch cover 6 is arranged with clutch spring 7 with the joint of described flange clutch sleeve 2, described clutch spring 7 ratchet 8 outer with being sleeved on flange clutch sleeve 2 is connected, and described ratchet 8 cooperates with ratchet 9.
Described braking shell 1 is wrapped with clutch outer member 10, and described ratchet 9 connects clutch driving lever 11, and described clutch driving lever 11 is connected with described clutch outer member 10 by Brake torsion spring 12.
The afterbody of described input gear shaft 3 is first gear 13, gear train in the braking shell 1 comprises described first gear 13, the first planet duplicate gear 14, the second planet duplicate gear 15, internal gear 16 and external toothing 17, the first planet duplicate gear 14, the second planet duplicate gear 15 is positioned at the both sides of described first gear 13, the back tooth of the first planet duplicate gear 14, the back tooth of the second planet duplicate gear 15 and 13 engagements of described first gear, the nipper of the first planet duplicate gear 14, the nipper of the second planet duplicate gear 15 meshes with described internal gear 16 and external toothing 17 respectively.
