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...

AI Technical Summary

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 rotation angle, the volume of the fuel injection pump rack is large when it is directly driven, and it cannot directly feedback the displacement of the diesel engine fuel injection pump rack, it is necessary to design an additional mechanism to ensure that the torque motor can be used as a diesel engine.
