Abstract

The invention discloses a hydraulic device that utilizes self-weight potential energy feedback to assist the output torque of a servo motor, including a fuel tank, a variable-speed hydraulic pump, a booster mechanism, a servo motor, and an accumulator. The booster mechanism is respectively connected to a variable-speed hydraulic pump and a servo motor. The booster mechanism is respectively led to the high-pressure oil port and the low-pressure oil return port. A second electromagnetic directional valve is arranged between the oil chambers of the low-pressure oil return port. Auxiliary cylinder and main oil cylinder; the present invention uses hydraulic pressure to push the rotor to drive the servo motor shaft and variable speed hydraulic pump shaft, so that the servo motor can use less output torque to achieve greater torque transmission to drive the variable speed hydraulic pump, so that the small power servo motor can It can provide higher power output in a short time, and start faster, output and adjustment control are more stable and precise, achieve energy saving effect, replace the coupling, reduce the structure volume and the power cost of the power source.

Description

A hydraulic device that utilizes self-weight potential energy to feed back the output torque of a servo motor technical field The present invention relates to the technical field of servo motors, in particular to a kind of self-weight potential energy feedback assisting servo motor output torque hydraulics. Background technique [0002] The servo motor can control the speed and position accuracy very accurately, and can convert the voltage signal into torque and rotational speed. In order to drive the control object, the rotor speed of the servo motor is controlled by the input signal and can respond quickly. In the automatic control system, It is used as an actuator, and has the characteristics of small electromechanical time constant and high linearity, which can convert the received electrical signal into electrical Angular displacement or angular velocity output on the crankshaft. When the servo motor is used, the power of the output and the control demand are la...
