Torque motor actuator of rotary diesel engine

Abstract

The invention provides a torque motor actuator of a rotary diesel engine, comprising a shaft, a bearing, a gearwheel, an angle sensor, a torque motor, a pinion, an eccenter, a controller and the like. The torque motor is arranged on the eccenter and is provided with the pinion; the pinion is mutually meshed with the gearwheel installed on the shaft; one end of the shaft is provided with the angle sensor which is connected with the controller to feed back the shaft angle to the controller; the output of the controller controls the torque motor. In the invention, the torque motor with small torque is adopted for torque amplification via a gear mechanism, which can realize larger torque, and a backlash eliminating mechanism and an angle position-limit mechanism are installed, which can better realize controlled electronic speed regulating function of diesel engine position.

Description

(1) Technical field [0001] The invention relates to a diesel engine position control type electronic speed regulation actuator, in particular to a marine diesel engine position control type electronic speed regulation actuator. (2) Background technology [0002] At present, the position-controlled electronic speed control actuators of diesel engines used on ships in our country basically use proportional electromagnets, torque motors or electro-hydraulic actuators as the moving elements of the actuators, which are respectively used for small, medium and high-power diesel engine speeds. control. As an electronic speed control actuator, the proportional electromagnet can only realize two-way movement by adding a return spring, so part of its output force is used to overcome the tension of the return spring, which affects its output force. [0003] Chinese Patent No.: ZL 97242519.5, the patent document named "Electromagnetic Actuator" discloses an electromagnetic actuator, the...

Problems solved by technology

Its disadvantages are: the reliability of single-winding coil and single sensor is low; the linearity of the rotation angle sensor is poor; the sensor has no gap elimination mechanism; the motion conversion mechanism is complicated, which reduces the response speed and control accuracy of the device

However, since the torque motor cannot reliably limit the
