发动机曲轴磨削质量影响发动机的性能和寿命,因此,一定要按照磨曲轴工艺规程进行,并注意下列要点:1 曲轴磨削量的计算。先根据曲轴的磨损程度选配适当尺寸的轴瓦,把轴瓦装在瓦座上,再装上螺栓,按规定的扭紧力矩拧紧,然后测量轴瓦内径尺寸。根据测量的尺寸再加上该种轴瓦要求的标准间隙(取中间数为宜),即可计算出曲轴的磨削量。这种按轴瓦实际尺寸磨轴的工艺,比直接按修理级别尺寸磨轴(磨轴又

Engine crankshaft grinding quality affect the performance and life of the engine, therefore, must be in accordance with grinding crankshaft process rules, and pay attention to the following points: 1 crankshaft grinding amount of calculation. First, according to the degree of wear of the crankshaft matching the appropriate size bush, the bearing bush mounted on the tile seat, and then install the bolt, tighten the required tightening torque, and then measure the bearing bore size. According to the measured size coupled with the kind of standard pad required by the gap (taking the middle appropriate), you can calculate the crankshaft grinding capacity. This method according to the actual size of shaft grinding shaft, grinding shaft size than the direct repair level (grinding shaft and
