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

[0010] The preferred embodiment of the present invention is further described below:

[0011] This structure consists of a main body 4, an elastic chuck 5, a block 6, an elastic reset device 8, a ball nut 9 on the actuator 1, and a gear rod 7 on the fuel injection pump 3. One end of the elastic reset device 8 is supported on the main body On the part 4, the other end is pressed on the elastic chuck 5. Elastic chuck 5 inner holes are triangular hole shape, and flange is arranged at the end. The elastic chuck 5 and the gear bar 7 are connected by two clamping blocks 6, the clamping blocks 6 and the elastic chuck 5 are connected in a triangle, and the clamping blocks 6 and the gear rod 7 are connected by a slot. 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. The clamping block 6 is made up of 2 pieces, and the shape is that a round platform is cut into two pieces at the center, and there is a...

Abstract

The invention belongs to the technical field of diesel engine electronic control, and relates to a numerically controlled diesel engine. The structure includes a main body, an elastic chuck, a block, an elastic reset device, a nut head, and an oil injection screw. One end of the elastic reset device is supported on the main body, and the other end is pressed on the elastic chuck. It is connected by two clamping blocks, the clamping block and the elastic chuck are connected in a triangle, and the clamping block and the gear bar 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 numerically controlled diesel engine. 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 to propose a numerically controlled diesel engine to achieve a gapless and flexible connection...
