A high-pressure common-rail diesel engine-driven common-rail pump intermediate gear installation device

Abstract

The invention discloses an installing device of a common rail pump intermediate gear driven by a high pressure common rail diesel engine. The installing device comprises a front end cover, a supporting body, a cover plate, a thrust ring, a large sealing ring, a small sealing ring and a positioning pin; and a high pressure common rail diesel engine intermediate gear installing hole is formed in the front end cover, the supporting body is arranged in the intermediate gear installing hole, the cover plate is arranged in the center of the end face of the left side of the supporting body, the small sealing ring is arranged on the right end face of the cover plate, the large sealing ring is arranged on the periphery of the right side of the supporting body, the thrust ring is arranged in the center of the end face of the right side of the supporting body, and the positioning pin is arranged on the end face of the right side of the supporting body and is correspondingly connected with a through hole in the thrust ring. According to the installing device of the common rail pump intermediate gear driven by the high pressure common rail diesel engine, the reasonable structure is adopted, the difficulties in mounting, demounting and adjustment of the common rail pump intermediate gear driven by the high pressure common rail diesel engine are solved, the performance of the high pressure common rail diesel engine is improved, and mounting and maintenance of the common rail pump intermediate gear are very convenient.

Description

technical field [0001] The invention belongs to the technical field of diesel engine machinery manufacturing, and mainly relates to a high-pressure common-rail diesel engine-driven common-rail pump intermediate gear installation device. Background technique [0002] High-pressure common rail diesel engine refers to a fuel supply machine that completely separates the generation of injection pressure and the injection process from each other in a closed-loop system composed of common rail pump, pressure sensor and electronic control unit (ECU). Its working principle is: the crankshaft gear drives the intermediate gears at all levels, which are transmitted layer by layer to the driving gear of the common rail pump. The extent to which the oil supply pressure of the diesel engine changes with the engine speed is greatly reduced, and the power performance and emission performance of the diesel engine are greatly improved. It is precisely because of the many advantages of common ...

AI Technical Summary

Problems solved by technology

[0008] When using the thrust ring, the thickness of the thrust ring is often adjusted, and the front cover must be opened to operate, and the adjustment process is very cumbersome;

[0009] 2. The lubrication effect of the intermediate gear assembly is not very good, causing it to directly affect the entire

[0011] Therefore, a more reasonable device is needed to solve the problems of difficult loading and unloading, inconvenient adjustment and insufficient lubrication of the existing high-pressure common rail diesel engine-driven common rail pump intermediate gear
