柴油机的进排气阀应按规定时刻开闭,喷油泵应按规定时刻供油。在安装正时齿轮时,必须将正时齿轮端面上装配标记对准,称为“安装正时”。倘若正时齿轮端面装配标记模糊不清或更换新的正时齿轮(端面无装配标记),应该怎样安装? 单缸柴油机以S195型为例,齿轮室内装有曲轴齿轮、凸轮轴齿轮、平衡轴齿轮、调速器齿轮和起动齿轮。 1平衡轴齿轮的正时安装转动曲轴,将活塞移到上止点,装上曲轴齿轮,然后将上下平衡轴平衡重块转到离活塞最远的位置,上下平衡重块的对称中心线应平行于气缸套中心线,将上下平衡轴齿轮装上,
Diesel intake and exhaust valves should be opened and closed at the specified time, fuel injection pump should be provided at the moment. When installing a timing gear, the mounting mark on the timing gear face must be aligned, called “Mounting Timing”. If the timing gear assembly mark is ambiguous or replace the new timing gear (no assembly mark on the end), how to install? Single-cylinder diesel engine to S195-type, for example, gear room equipped with crankshaft gear, camshaft gear, balance shaft Gears, governor gears and starting gears. 1 balance shaft gear timing installation Rotate the crankshaft, the piston to the top dead center, fitted with crankshaft gear, and then balance the shaft balance weight to the farthest away from the piston position, balance the center of gravity balance should be Parallel to the cylinder liner centerline, the upper and lower balance shaft gear mounted,
