Abstract
The utility model relates to a coaxial double speed output planetary gear speed reducing motor, belonging to the speed reducing motor technology field, which is applied to the direct drive of a washing machine; wherein the high speed output is used to drive a dewatering barrel, and the low speed output is used to drive an impeller. The utility model is characterized in that the motor adopts a hollow shaft, one end of the hollow shaft drives a sun gear of the planetary gear and its other end is the high speed output drive end. A planetary wheel of a planetary speed reducer is connected with the low speed output shaft, and the low speed output shaft passes through the hollow shaft of the motor. The utility model can improve the drive efficiency of the system.
Description
Affiliated technical field
The utility model relates to a kind of coaxial double speed output planetary gear reduction motor, and this reducing motor adopts the planetary gear speed-reduction technology.
Background technology
The impeller of single container washing and extracting machine and dehydration barrel are carried out high driven at low speed by motor respectively.At the washing state, the impeller of washing machine slowly runs, and the rotating speed of impeller is between 30 rev/mins to 150 rev/mins; At dewatering state, the rotating speed of dehydration barrel is between 800 rev/mins to 1500 rev/mins.Present scheme is a motor process pulley decelerates, drives impeller or dehydration barrel respectively.Because pulley decelerates is smaller, efficiency of motor is lower, and the efficient of pulley decelerates is lower simultaneously, causes the washing machine whole efficiency lower.
Number of patent application: 200620046652.X has proposed the solution of the washing machine harmonic gear reducing motor of a kind of direct shaft coupling impeller and dehydration barrel.Harmonic gear is suitable for the application scenario than the big retarding ratio, and cost is higher.
Summary of the invention
The utility model proposes a kind of solution of coaxial double speed output planetary gear reduction motor.When coaxial double speed output planetary gear reduction motor is used for washing machine, to export at a high speed to be used to drive dehydration barrel, low speed output is used to drive impeller, can improve the efficient of washing machine.
Scheme of the present utility model is that motor adopts hollow shaft, and an end of hollow shaft drives planetary sun gear, and the other end is as exporting drive end at a high speed.The planetary gear of planetary reducer connects the low speed output shaft, and its low speed output shaft passes the hollow shaft of motor, is used for low speed output.
