Owing to be subjected to restrictions such as diesel engine cost, accessory arrangement space, at present, adopt first generation speed regulator---centrifugal mechanical governor mostly at the speed regulator of light duty diesel engine (or diesel generating set).Though adopted the stepper motor direct driving in the minority electrons speed regulator actuator, it uses the tooth bar of flexible collar and oil feed pump to realize interlock in diesel-engine body, and cargo handling process is numerous and diverse.
Summary of the invention
The purpose of this utility model provides a kind of electronic speed regulator and directly pushes away actuator, be used to solve the electronic speed regulator actuator installation of the tooth bar interlock that substitutes existing centrifugal mechanical governor and use flexible collar and oil feed pump and the convenience problem of debugging, it adopts integrated design, original diesel engine structure is done under the situation of any change need not, realize integral installation, improved installation, use, debugging and the maintainability of product.
The purpose of this utility model can adopt following technological scheme to realize: mainly by stepper motor, fixing frame and mechanical transmission mechanism constitute, stepper motor and fixing frame are connected and fixed, mechanical transmission mechanism is arranged on the fixing frame, described mechanical transmission mechanism comprises swing arm, linkage rod and the connecting rod and the connecting sheet that are used for follow-up adjustment linkage rod position, one end of swing arm and the motor shaft of stepper motor are connected, the other end is connected with connecting rod, connecting sheet one end is connected with connecting rod, the other end is connected with linkage rod one end, and the other end of linkage rod contacts with the oil feed pump tooth bar is corresponding; Connecting rod is connected with the oil feed pump tooth bar by extension spring; Be socketed with reduction torsion spring on the described swing arm.
On the described fixing frame pilot hole is set, linkage rod is positioned at pilot hole, realizes translation.
The end of described linkage rod is provided with tack, and linkage rod tack is close to oil feed pump tooth bar one end and realizes interlock.
Connecting rod is provided with the spring hanging groove, and an end of extension spring is arranged in the spring hanging groove, and its other end is connected with pump rack.
On fixing frame, be fixed with two stop screws that are used to limit the minimum and maximum position of swing arm.
The utility model adopts the independent body structure, the main stepper motor that adopts drives a cover mechanical transmission, utilize the mounting point of the speed-regulating handle of original mechanical speed governor, be connected with the gear box cover of diesel engine, transmission and connected element extend in the gear-box, controller box is directly installed on the stepper motor tail end, has realized the integrated installation of speed regulator control section and actuator.The utility model need not original diesel engine structure is done any change, thereby improves the Economy and the adaptability of product.Owing to do not change original diesel engine structure, thereby both guaranteed the convenience that electronic speed regulator actuator installs, uses and debug, saved development cost again, improved the Economy of product; Owing to adopt the independent body structure, directly driving, thus self arrangement convenience, and simple in structure, stable drive, and stable and reliable operation.Can not only conveniently install, and can improve the speed adjusting performance of speed regulator.The utility model can have now fully and substitute light duty diesel engine (or diesel generating set) mechanical speed governor; it adopts stepper motor to drive the direct transmission of four-bar linkage; can be converted into approximate straight line motion with rotatablely moving and directly regulate the oil feed pump rack displacement; automatically controlled and actuator adopts the independent body structure; integrated design has realized the transmission of no gap and has run into the emergency shutdown that does not have under instruction, the failure condition.
