190柴油机在高速运转中,其径向惯性力是由装在曲轴上的平衡块来抵消的,安装时要求平衡块两只螺栓的紧度为7～8公斤·米。如拧紧力矩不合适,工作中会使两只螺栓松动而折断,容易造成曲轴折断、连杆弯曲,甚至打坏机体等严重事故。因此,在使用中,应经常注意和检查螺栓的 190 Diesel engine in high speed operation, the radial inertial force is by the balancer mounted on the crankshaft to offset, the installation requires the balance of two bolts tightness of 7 to 8 kg · m. If the tightening torque is not suitable, the work will make two bolts loose and broken, easily lead to crankshaft breakage, connecting rod bending, or even damage the body and other serious accidents. Therefore, in use, should always pay attention to and check the bolt
