Summary of the invention
The purpose of the utility model provides a kind of rational in infrastructure, and volume is little, reduces the refrigerator MOD device of cost of manufacture.
The utility model is that the technical scheme that achieves the above object is: a kind of refrigerator MOD device; Comprise casing, be installed in door-plate and motor on the casing; It is characterized in that: said motor is installed between the mounting groove and case lid of casing one side; The casing of motor is positioned at pole plate one side has the gear dividing plate surely, and the casing end is equipped with cover, and electric machine main shaft passes the gear dividing plate and is bearing on the cover; The above gear reduction that slows down of level Four is installed between gear dividing plate and the cover; The engagement of the input gear of gear reduction and the driving gear of electric machine main shaft, the output gear of gear reduction is connected with driven wheel on being installed in output shaft, and output shaft is bearing on gear dividing plate and the cover; The trough floor that output shaft passes cover and casing mounting groove is connected with the door-plate end, and two friction plates that are installed on the output are separately positioned in the frictional groove of driven wheel both sides.
The utility model is equipped with the gear dividing plate in the casing of motor, gear reduction is installed on gear dividing plate and the cover, and motor and gear reduction are integrated in the casing; Rational in infrastructure, compact, volume is little, and the installing hole that especially installing hole on gear dividing plate and the cover all can electric machine main shaft is a benchmark; Good manufacturability not only; And each part be easy to processing, can improve assembly precision, so can reduce the cost of manufacture of throttle setting.The utility model is installed two friction plates on output shaft; Be separately positioned on through two friction plates in the frictional groove of both sides of driven wheel; When output gear drives the positive and negative rotation of driven wheel, reduce the rotating speed of output shaft through two friction plates, and increase the output torque of output shaft; At low temperatures under the state, overcome air door and frozen the resistance that the back produces and can not reliably open and closed not tight problem.
