Double-outputting torque speed reducing electric machine

Abstract

A speed reduction motor with double output-torque is prepared as setting two one-way bearings on motor rotary shaft as one being positive rotation bearing and another being negative rotation bearing, setting two sets of gear groups in gear speed reduction mechanism as one being same-direction speed reduction gear group and another being reverse-direction speed reduction gear group, jacketing two input teeth separately on two one-way bearings and firm-jacketing two output teeth commonly on output shaft.

Description

technical field [0001] The invention relates to a reduction motor, especially the improvement of its reduction mechanism. Background technique [0002] Geared motors are widely used in mechanical equipment. The existing geared motors are composed of a motor and a gear reduction mechanism. According to the structure of the reduction mechanism, they are divided into fixed speed ratio geared motors and variable speed ratio geared motors. The speed ratio reduction motor is adjusted by adjusting the transmission ratio of the gear, and the adjustment range is wide. However, on some equipment that only needs to be adjusted in two gears, fast and slow, it is not applicable due to its complex structure and high cost, and its adjustment requires mechanical action. It is not conducive to automatic control; while using a fixed speed ratio reduction motor, when speed regulation is required, the motor speed can be adjusted by adjusting the motor voltage and other parameters to achieve the...

The speed ratio reduction motor is adjusted by adjusting the transmission ratio of the gear, and the adjustment range is wide. However, on some equipment that only needs to be adjusted in two gears, fast and slow, it is not applicable due to its complex structure and high cost, and its adjustment requires mechanical action. It is not conducive to automatic control; while using a fixed speed ratio reduction motor, when speed regulation is required, the motor speed can be adjusted by adjusting the motor voltage and other parameters to achieve the speed adjustment of the output shaft, but because the motor power decreases, the output torque decreases accordingly. Small

For example, when an electric vehicle goes uphill, it needs to reduce the speed and increase the torque. The existing technology uses a high-power motor to meet the power needs of heavy loads such as loads and uphill loads. High power is required, resulting in a waste of power configuration and increasing the cost of the vehicle
