2 S195柴油机曲柄连杆机构特点和调整 S195柴油机具有结构紧凑、简单、体积小、重量轻和功率大的特点。它由曲柄连杆机构、配气机构、供给系统、润滑系统、冷却系统等部分组成。曲柄连杆机构是S195柴油机的重要组成部分,由活塞连杆组、曲轴飞轮组和平衡机构等组成。这些零部件都是主要运动件,它们的主要功用是组成燃烧室,柴油在燃烧室内燃烧产生高压燃气推动活塞运动,又通过连杆把活塞的往复运动转换成曲轴的旋转运动,然后由飞轮输出动力,带动机器工作。 2.1 活塞连杆组 S195柴油机活塞连杆组由活塞,活塞环、活塞销、连杆以及轴瓦、衬套等零件组成(图1)。
2 S195 Diesel Engine Crank and Linkage Mechanism Features and Adjustments The S195 diesel engine is compact, simple, small, lightweight and powerful. It consists of crank connecting rod mechanism, valve mechanism, supply system, lubrication system, cooling system and other components. Crank and connecting rod mechanism is an important part of S195 diesel engine. It consists of piston rod set, crankshaft flywheel set and balance mechanism. These parts are the main moving parts, their main function is to form a combustion chamber, diesel combustion in the combustion chamber to produce high-pressure gas to promote piston movement, and through the connecting rod piston reciprocating motion into crankshaft rotation, and then by the flywheel output Power, driving the machine work. 2.1 Piston rod set S195 diesel piston rod set by the piston, piston ring, piston pin, connecting rod and bearing bush, bushings and other components (Figure 1).
