四缸柴油机正时齿轮系设计

Design of Timing Gear System of Four-cylinder Diesel Engine

基于某六缸柴油机正时齿轮系进行同系列四缸机的齿轮系设计,根据平衡机构安装要求,增加左、右平衡轴齿轮及其驱动惰轮,重新布置油泵齿轮位置,使不同速比要求的高压油泵可以安装在齿轮室的同一位置。

The paper designed a gear system of 4-cylinder engine based on the timing gear train of a six-cylinder diesel engine, added left and right balancing shaft gears and their driving idle gears according to the requirement of the balance mechanism, rearranged the position of pump gear so that the high-pressure oil pump with different speed ratios could be installed in the same position of the gear box.
