At present, known reduction clutch of washing machine is to realize that by speed-reducing clutch it is made up of parts such as reduction box, unilateral bearing, housing, belt pulley, impeller axle, clutch spindles.When washing machine need be realized rate conversion, need apply bigger mechanical force by external devices such as traction electric machines, just can realize conversion; Owing to reasons such as the characteristics of himself forming, processing requests, when high speed, can only realize unidirectional high speed rotation; And have production and processing requirement height, and the cost height, use, installation etc. are more loaded down with trivial details.
Summary of the invention
In order to solve cost height, production and processing more complicated that present use reduction clutch of washing machine exists, can only to realize deficiency such as unidirectional high speed rotation, the utility model provides a kind of novel reduction clutch of washing machine, this device not only can be realized the function that present reduction clutch of washing machine has, and can overcome present reduction clutch of washing machine complex structure, cost height, can only unidirectional high speed rotation etc. deficiency.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of novel reduction clutch of washing machine, include decelerator, the dynamic power shaft of described decelerator, main output shaft and output sleeve, it is characterized in that the driving shaft of described main output shaft as agitation wheel for washing machine, be provided with clutch between described power input shaft and the output sleeve, the upper and lower slip of clutch energy slides into certain position on the clutch, realize effectively coupling with power input shaft, output sleeve by mechanical connecting mode simultaneously.
Described novel reduction clutch of washing machine is characterized in that described mechanical connecting mode is the mode that digital, spline cooperate with keyway, teeth groove.
Described novel reduction clutch of washing machine, it is characterized in that described clutch is meant clutch tooth cover, power input shaft and output sleeve lower end have external tooth respectively, the clutch tooth puts, all there is internal tooth the lower end, described clutch tooth puts, lower slider, the clutch tooth puts, the internal tooth of lower end respectively with output sleeve, power input shaft on external tooth be meshed corresponding.
Described novel reduction clutch of washing machine is characterized in that the rotating ratio between described agitation wheel for washing machine driving shaft and the power input shaft is 1: 1-20.
Described novel reduction clutch of washing machine is characterized in that described washing machine is automatic washing machine or semi-automatic washing machine or agitator type washing machine.
Utility model is on the common deceleration device basis that common single cylinder or two-tub washing machine adopted, by designing a clutch that can be free to slide, achieve the decelerator main output shaft drive the independent two-way rotation of impeller and and decelerator main output shaft, synchronous two-way the rotating freely of output sleeve; When the user needed the slow-speed of revolution to rotate, the clutch that is free to slide separated the decelerator power input shaft with the reducer output shaft cover, drive by exterior power, realized that the decelerator main output shaft rotates freely with clockwise, counterclockwise high pulling torque, the slow-speed of revolution; In the time of need rotating at a high speed as the user, the clutch that is free to slide effectively is coupled reducer output shaft cover and decelerator power input shaft, decelerator power input shaft and output sleeve are coupled as one, drive by exterior power, realize that decelerator main output shaft and clockwise synchronously, the counterclockwise high rotating speed of output sleeve rotate freely; Thereby functions such as the washing of realization washing machine, dehydration; The utility model has been simplified the reduction clutch structure of present employing greatly, has realized purposes such as low-cost, that production and processing is simple.
The beneficial effects of the utility model are, can simplify currently used reduction clutch greatly, reduce cost and the production and processing requirement, and structure is very simple, and are convenient.

The specific embodiment
Referring to accompanying drawing 1,2.
A kind of novel reduction clutch of washing machine, include decelerator 1, described decelerator 1 has main output shaft 2 and output sleeve 4, power input shaft 5, main output shaft 2 is as the driving shaft of agitation wheel for washing machine, be provided with clutch 3 between power input shaft 5 and the output sleeve 4, clutch 3 is meant clutch tooth cover, power input shaft 5, output sleeve 4 lower ends have external tooth respectively, the clutch tooth puts, there is internal tooth the lower end, described clutch tooth be enclosed within gravity or the external force effect can more than, lower slider, clutch tooth cover upwards slides into certain position, its upper end and the external tooth engagement of being located on output sleeve 4 outer walls, the external tooth engagement of lower end and power input shaft 5 lower ends, at this moment, output sleeve 4, power input shaft 5 rotates simultaneously, and main output shaft 2 also rotates in the lump.When the external tooth on the clutch 3 disengaging output sleeves 4, output sleeve 4 can not rotate, and power input shaft 5 rotates with main output shaft 2.
