China Patent No.: ZL 97242519.5, name are called in the patent document of " electromagnetic actuator " and disclose a kind of electromagnetic actuator, and its electromagnet coil is that simplex winding coil, sensor are single rotary angle transmitter; Final controlling element beam warp synchronizing bar on the follower lever of position transducer assembly and the final controlling element body joins together, to reach the purpose that the straight line motion of armature is converted to the required rotation of rotary angle transmitter; The final controlling element axle is realized no gap transmission between itself and pump rack by joiner.Its shortcoming is: the reliability of simplex winding coil and single-sensor work is low; The rotary angle transmitter poor linearity; Sensor elimination very close to each other mechanism; The movement conversion mechanism complexity has reduced speed of response, the control accuracy of installing.In sum, its performance and reliability can not satisfy the requirement of high-pressure fuel pump of diesel engine to its drive unit.
Adopt the critical component of motor as diesel engine positioning control formula electronic speed regulation final controlling element, obtained research, as Chinese patent application number be in 02243850 the patent document, a kind of straight line moving type electronic control dynamoelectric accelerograph final controlling element is proposed, two links, manual adjustment knob, manual/electric change-over switch mechanism, axial limiting body, the circuit for controlling motor that have housing, minisize dc reducing motor, reducing gear, be in transmission connection by screw thread.This structure function complexity adopts direct current generator as moving element, and reducing gear does not have backlash eliminator, and the screw thread transmission is difficult to guarantee precision.
Chinese patent application number is in 200620113604 the patent document, to propose a kind of throttle actuator, and this final controlling element comprises: controller, data capture conditioning device, servocontroller and actuating motor.It is simple in structure that this final controlling element adopts actuating motor to have, good reliability, and advantage of high precision, but actuating motor does not have corner spacing firmly, does not have safety protection.
In addition, the employing limited angle torque motor has been proposed as the diesel engine speed regulation final controlling element at Harbin Engineering University's journal paper " limited angle torque motor is as the design studies of diesel engine speed regulation actuator " in August, 2008.Limited angle torque motor is compared design with the usual forces torque motor complicated, and Costco Wholesale is higher, and control is complicated.During as final controlling element, volume is bigger, therefore uses to be restricted.
Torque motor is simple in structure, and output torque is big, can realize continuous stall, technology maturation, weight and volume is little, and commercial Application is preferably arranged, with its main motor element, can realize the diesel engine speed control in the more high-power scope as diesel engine positioning control formula electronic speed regulation final controlling element.But because torque motor can not limit rotation angle reliably, when directly driving during injection pump rack volume bigger, and can not directly feed back problems such as diesel injection pump rack displacement amount, therefore, must guarantee the reliable and secure use of torque motor by design one cover additional mechanism providing additional operation as diesel engine speed regulation actuator.
(3) summary of the invention
The object of the present invention is to provide a kind of speed of response fast, be applicable to rotating speed control, a kind of torque motor actuator of rotary diesel engine that reliability is high than the diesel engine in the broad power band.
The object of the present invention is achieved like this:
It comprises axle, bearing, gearwheel, angle transducer, torque motor, small gear, eccentric wheel, controller, on torque motor is installed in the eccentric wheel, the center of circle disalignment in the hole of mounting torque motor on eccentric axle center and its, small gear is installed on the torque motor, and small gear and the gearwheel that is installed on the axle are meshing with each other, and at an end of axle angle transducer are installed, angle transducer connection controller is fed back to controller, the output control moment motor of controller with the corner of axle.
