Description
Technical field
The utility model relates to a kind of part of washing machine, particularly a kind of clutch for washing machine.
Background technology
Washing machine is a requisite home appliance in the life, and along with the raising day by day of continuous progress in science and technology and people's living standard, people are also more and more higher to the requirement of washing machine.
The groundwork state of washing machine is divided into washing operating mode and dehydration condition.In washing during operating mode, impeller rotates and interior bucket is static, and impeller drives water and clothing and rotates and carry out washing work; And when dehydration condition, impeller and interior bucket rotate synchronously, clothes dewatering is dried, under the driving of a drive motors, finish above-mentioned two kinds of operating modes in order to reach, one all can be provided with clutch in washing machine, and existing washing machine internal clutch mostly adopts the cooperation of ratchet, ratchet and clutch driving lever, and there are shortcomings such as structure is comparatively complicated, volume is big, control is dumb in this arrangement of clutch.
The utility model content
The purpose of this utility model be to provide a kind of simple in structure, volume is little, transmission control system clutch for washing machine flexibly.
The technical scheme that realizes the utility model purpose is: a kind of clutch for washing machine, have driving shaft and propeller shaft sleeve, drive shaft turns is arranged in the propeller shaft sleeve, it is fixedly connected drive down, the outer socket solenoid of described propeller shaft sleeve, solenoid has profile of tooth clutch circle, profile of tooth clutch circle above-below direction is slidingly arranged on the propeller shaft sleeve and with the propeller shaft sleeve spline and is connected, profile of tooth clutch circle lower end has equally distributed at least 2 clutch teeth, described drive is positioned at profile of tooth clutch circle below, and the clutch tooth corresponding position of itself and profile of tooth clutch circle lower end is provided with slot.
Be provided with spring between the solenoid of above-mentioned clutch for washing machine and the profile of tooth clutch circle.
The outer socket integrated pallet of the propeller shaft sleeve of above-mentioned clutch for washing machine, fixedly connected coil retainer under the integrated pallet, described solenoid is fixedly connected on the coil retainer.
The profile of tooth clutch circle lower end of above-mentioned clutch for washing machine is 10 clutch teeth of distribution evenly, and each clutch tooth is down the big little centrum that, and the slot shape and the clutch odontoid of described drive match.
The profile of tooth clutch circle lower end clutch tooth of above-mentioned clutch for washing machine is fan-shaped cone, and the slot of described drive is a fan groove.
The utlity model has following characteristics: (1) the utility model adopts electromagnetic clutch mechanism, compact conformation, little, the precise control of volume; (2) gear shaping of clutch gear ring of the present utility model is evenly to distribute, and is stressed even; (3) gear shaping of clutch gear ring of the present utility model is for going up little cone down greatly, and drive slot shape and gear shaping shape match, and grafting cooperates stable, and difficult the disengaging is reasonable in design, practical in the high speed rotating process.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a sectional perspective explosive view of the present utility model.
The specific embodiment
See Fig. 1 and Fig. 2, the utlity model has driving shaft 1 and propeller shaft sleeve 2, driving shaft 1 rotates and is arranged in the propeller shaft sleeve 2, and it is fixedly connected drive 3 down; Propeller shaft sleeve 2 outer socket integrated pallets 7,7 times fixedly connected coil retainers 8 of integrated pallet, coil retainer 8 fixedly connected solenoids 4, solenoid 4 has profile of tooth clutch circle 5, profile of tooth clutch circle 5 above-below directions are slidingly arranged on the propeller shaft sleeve 2 and with propeller shaft sleeve 2 splines and are connected, profile of tooth clutch circle 5 lower ends are 10 clutch teeth 51 of distribution evenly, each clutch tooth 51 is fan-shaped cone, drive 3 is positioned at profile of tooth clutch circle 5 belows, clutch tooth 51 corresponding positions of itself and profile of tooth clutch circle 5 lower ends are provided with slot 31, slot 31 is the fan groove that matches with clutch tooth 51, slot 31 sizes are provided with spring 6 greater than clutch tooth 51 size bottom between solenoid 4 and the profile of tooth clutch circle 5.
The impeller of washing machine and driving shaft 1 are connected, interior bucket is connected with propeller shaft sleeve 2, integrated pallet 7 links to each other with the outer bucket of washing machine, the groundwork state of washing machine is divided into washing operating mode and dehydration condition, when washing machine is in the washing operating mode, solenoid 4 is in charged attracting state, profile of tooth clutch circle 5 overcomes spring 6 under the magnetic effect of solenoid 4 active force upwards slides, the clutch tooth 51 and the drive 3 of profile of tooth clutch circle 5 are in disengaged position, this moment, drive motors drove driving shaft 1 rotation, driving shaft 1 drives impeller and rotates, and interior bucket is static relatively, has formed the washing operating mode of washing machine.
When washing machine is in dehydration condition, solenoid 4 dead electricity, profile of tooth clutch circle 5 under the effect of spring 6 and self gravitation to lower slider, the clutch tooth 51 of profile of tooth clutch circle 5 lower ends inserts in the slot 31 of drive 3, profile of tooth clutch circle 5 and drive 3 lockings have formed washing machine impeller and the synchronous dehydration condition that rotates of interior bucket under a power source.
