在检查校对齿轮室内的曲轴齿轮、惰齿轮、喷油泵齿轮、凸轮轴齿轮的记号时,不知曲轴要转几圈才能使它们之间的记号重新对在一起。如心中无数越转越乱。下面介绍一种又快又简便的方法。以105系列柴油机为例,如图所示。事先数一数惰齿轮和曲轴齿轮的齿数,105系列柴油机惰齿轮是38齿,曲轴齿轮是23齿。把惰齿轮和曲轴齿轮齿数相乘,是两齿轮齿数的公倍数,即:38×23=874,因此各齿轮之间有如下关系:
In checking the calibration of the gear chamber crank gear, idler gear, fuel pump gear, camshaft gear markings, I do not know the crankshaft to turn a few laps in order to make the mark between them back together. If the hearts of countless more turn chaos. Here’s a quick and easy way. To 105 series diesel engine, for example, as shown. Counting the number of teeth on one of the idler and crankshaft gears, the 105-series diesel idler gear has 38 teeth and the crankshaft gear has 23 teeth. The multiplication of the number of teeth of the idler gear and the number of the crankshaft gear is the common multiple of the number of teeth of the two gears, that is: 38 × 23 = 874, so the following relations among the gears are as follows:
