S195柴油机采用的是双轴平衡机构,其作用是使活塞连杆组在运动中产生的往复惯性力得到平衡。若平衡轴在机器上安装不当时,不仅不能起到平衡作用,反而会加剧机器的振动,损坏零件,甚至出现重大事故。因此在平衡轴齿上一般都标有安装记号,装配时必须使各齿轮记号对正。但在长期的使用过程中,由于上、下平衡轴的齿轮键槽损坏,需要重新开槽时;或者齿轮上的记号 S195 diesel engine uses a biaxial balance mechanism, its role is to reciprocate the piston rod set reciprocating inertia forces generated by the balance. If the balance shaft is improperly installed on the machine, not only can it not play a balancing role, it will aggravate the vibration of the machine, damage parts, and even cause a serious accident. Therefore, the balance shaft teeth are generally marked with the installation mark, the assembly must make the gear mark alignment. However, during long-term use, due to damage to the keyway of the upper and lower balance shafts and the need to re-groove, or markings on the gears
