Abstract

The invention relates to a balance shaft of a two-cylinder diesel, a driving cam 2 of a high-pressure oil pump is arranged near the left shaft neck 1 of the balance shaft, and a balance weight 3 is arranged between the driving cam and the right shaft neck 4 of the high-pressure oil pump; the balance shaft of a two-cylinder diesel can meet the requirements of high rotation and high load for the diesel, and can reduce the vibration and noise of the two-cylinder diesel; simultaneously, the balance shaft integrated with the driving cam and the balance weight of the high-pressure oil pump of the diesel not only meets the balance requirement of the two-cylinder diesel, but also realizes the function of the driving high-pressure oil pump; and the invention improves the comfort of the diesel and decreases the cost of the diesel, and has simple structure, easy production and processing and high practicality.

Description

technical field [0001] The invention relates to a balance shaft of an engine, in particular to a balance shaft of a two-cylinder diesel engine. Background technique [0002] In order to meet the vibration and smoothness requirements of the diesel engine, a balance shaft needs to be added to the two-cylinder diesel engine to reduce the vibration and noise of the whole machine. The function of the balance shaft of the traditional two-cylinder diesel engine is only the function of a single balance shaft. So far, there has not been a structure integrating a high-pressure oil pump driving a cam and a balance weight on a two-cylinder diesel engine. Contents of the invention [0003] The object of the present invention is to provide a balance shaft of a two-cylinder diesel engine, which not only meets the requirements of the two-cylinder diesel engine to reduce the vibration and noise of the whole machine, but also drives the high-pressure oil pump of the diesel engine, so as to...
