Problems solved by technology

[0002] There are many types of connection between the electronically controlled actuator of the diesel engine and the fuel injection pump at present. Most of them are connected by pins, and some are connected by screws. The main disadvantages of the traditional connection method are as follows: easy to get stuck; The gear rods of the fuel injection pump are not synchronized, and there is a small amount of hysteresis, which greatly reduces the adjustment accuracy of the system; the assembly process is complicated, and the requirements for assembly and parts processing are high

Embodiment Construction

[0012] Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described further:

[0013] Such as figure 1 As shown, this structure includes an intermediate body 4, a spring plate 5, a block 6, a return spring 8, a ball nut 9 on the actuator 1, and a gear rod 7 on the fuel injection pump 3, etc., and one end of the return spring 8 is supported in the middle On the body 4, the other end is pressed on the spring disk 5. The inner hole of the spring disk 5 is a tapered hole with a flange at the end. Spring plate 5 is connected with tooth bar 7 by two blocks 6, and block 6 adopts taper surface to connect with spring plate 5, and block 6 adopts draw-in groove to connect with tooth bar 7. The gear rod 7 cuts a rectangular ring groove on the circumference for the end of the cylinder, and the end face is a circular plane. Such as figure 2 As shown, the clamping block 6 is composed of 2 pieces, and the shape is a circular platform cut into...

Abstract

The invention belongs to the technical field of diesel engine electronic control, and relates to a structural device for connecting a diesel engine operating system and an oil pump. The structure includes an intermediate body, a spring plate, a block, a return spring, a ball nut on the actuator, and a gear rod on the fuel injection pump. One end of the return spring is supported on the intermediate body, and the other end is pressed on the spring plate. It is connected with the gear rod through two clamping blocks, the clamping block and the spring disk are connected by a tapered surface, and the clamping block and the gear rod are connected by a clamping groove. The beneficial effects of the present invention are: high precision, convenient disassembly, not easy to get stuck, and more reliable connection mode.

Description

technical field [0001] The invention belongs to the technical field of diesel engine electronic control, and relates to a structural device for connecting a diesel engine operating system and an oil pump. Background technique [0002] There are many types of connection between the electronically controlled actuator of the diesel engine and the fuel injection pump at present. Most of them are connected by pins, and some are connected by screws. The main disadvantages of the traditional connection method are as follows: easy to get stuck; The gear rods of the fuel injection pump are not synchronized, and there is a small amount of backlash, which greatly reduces the adjustment accuracy of the system; the assembly process is complicated, and the requirements for assembly and parts processing are high. Contents of the invention [0003] The purpose of the present invention is just to solve the deficiencies of the prior art, and propose a structural device connecting the operat...
