Abstract
The invention discloses a direct drive of a novel washing machine, which comprises a reducer provided with a power input shaft, an output shaft and an output shaft bushing. The output shaft is taken as the impeller driveshaft of the washing machine, which is characterized in that the motor shaft of the washing machine is in effective mechanical connection with the output shaft through a coupling. A clutch is arranged between the power input shaft and the output shaft bushing, and a motor seat is provided with a brake block. The clutch can be in forward and backward sliding. When the clutch slides up to a certain position, the effective coupling can be achieved with the power input shaft, the output shaft bushing and the brake block through a mechanical linking method. With the invention, the indirect drive of washing machine adopted currently is significantly simplified. The costs and the production process requirements are also reduced. Moreover, the structure is extremely simple and convenient.
Description
Technical field
The present invention relates to a kind of part of washing machine, specifically is a kind of novel direct driving apparatus of washing machine by motor direct-drive impeller driving shaft, decelerator, can freely realize small-power, high rotating speed and high pulling torque, freely change than efficient between the slow-speed of revolution.
Background technology
At present, known drive unit of washing machine is to be realized driving indirectly by parts such as motor, belt pulley, belt, speed-reducing clutchs, and the core component speed-reducing clutch generally 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; The ubiquity production and processing requires high, and the cost height such as uses, installation is more loaded down with trivial details, efficient is low, noise is big at deficiency.
Summary of the invention
For deficiency such as solve cost height, production and processing more complicated that the indirect drive unit of present use washing machine exists, efficient is low, noise is big, the invention provides a kind of novel direct driving apparatus of washing machine, this device not only can be realized the function that the indirect drive unit of present washing machine is had, and can overcome that the indirect drive unit cost of present washing machine height, complex structure, difficulty of processing are big, deficiency such as inefficiency, noise are big.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of novel direct driving apparatus of washing machine, include decelerator, the dynamic power shaft of decelerator, output shaft and output sleeve, output shaft is characterized in that as the impeller driving shaft of washing machine the motor for washer axle is by shaft coupling and the effective mechanical connection of output shaft; Be provided with clutch between described power input shaft and the output sleeve, on the described motor cabinet brake mount is installed, the upper and lower slip of clutch energy slides into certain position on the clutch, can realize effectively coupling by mechanical connecting mode with power input shaft, output sleeve, brake mount.
Described mechanical connecting mode is the mode that digital, spline cooperate with keyway, teeth groove.
Described clutch is meant clutch tooth cover, power input shaft, output sleeve lower end have external tooth respectively, internal tooth is arranged on the brake mount, the clutch tooth puts, the stage casing has internal tooth respectively, there is external tooth clutch tooth cover lower end, described clutch tooth cover can upper and lowerly slide, and described clutch tooth puts, the internal tooth in stage casing is meshed correspondingly with the external tooth of power input shaft, output sleeve lower end respectively, and the external tooth of clutch tooth cover lower end is meshed corresponding with the internal tooth on the brake mount.
Rotating ratio between described output shaft and the power input shaft is 1: 1-20.
Described washing machine is automatic washing machine or semi-automatic washing machine or agitator type washing machine.
Motor shaft is passed through a shaft coupling and the effective mechanical connection of clutch output shaft, realize electrical isolation simultaneously, by the clutch of the upper and lower slip of energy, when the user selects to rotate at a high speed, the decelerator power input shaft effectively is connected with the motor for washer axle by shaft coupling; Clutch is up along power input shaft, with power input shaft, output sleeve mechanical connection, directly drives by motor shaft simultaneously, realizes the synchronous rotation between motor shaft, reducer output shaft (impeller driving shaft), the reducer output shaft cover three; When needing skidding, clutch is descending, make on the brake mount of clutch sleeve outside motor shaft, the external tooth of clutch sleeve lower end and the engagement of the internal tooth on the brake mount, simultaneously, the internal tooth in the going up of clutch sleeve, stage casing respectively with output sleeve, power input shaft on the external tooth engagement, washing machine is realized the purpose of skidding; Clutch continues descending, then on the clutch, the internal tooth in stage casing breaks away from the external tooth on output sleeve, the power input shaft, have only the external tooth and the engagement of the internal tooth on the brake mount of clutch sleeve lower end, at this moment, the motor for washer axle drives the power input shaft rotation, and then the rotation of decelerator drive output shaft, and agitation wheel for washing machine rotates thereupon, at this moment, clutch is inoperative.Thereby functions such as the washing of realization washing machine, dehydration; The present invention has simplified the indirect driving device structure of washing machine of present employing greatly, has dispensed such as parts such as belt, belt pulleys, has realized low-cost, purposes such as production and processing is simple, efficient energy-saving, noise is low, simple in structure, fault rate is low.
The invention has the beneficial effects as follows, can simplify the indirect drive unit of currently used washing machine greatly, reduce cost and the production and processing requirement, structure is very simple, and is convenient.
