摘　　要：曲轴是发动机最重要的部件之一,其工作原理是在连杆的配合下,将活塞中汽油燃烧产生的气压转变为力矩,从而产生机械动能。在发动机工作过程中,曲轴会受到连杆往复运动和自身旋转产生的惯性力的共同作用,因此容易出现弯曲、扭曲变形及裂纹问题。同时在曲轴的工作过程中,很难保证其轴颈的润滑,轴颈部分常出现过渡磨损的情况。因此,在曲轴的生产加工工艺上应保证曲轴的材质、硬度以及精准度达到要求,并且在后续的保养维护工作中具备合理完善的修理方法。该文就发动机曲轴的加工及损伤的修理方法进行分析。The crankshaft is one of the most important components of the engine.Its working principle is to convert the air pressure generated by gasoline combustion in the piston into torque with the cooperation of the connecting rod,so as to produce mechanical kinetic energy.During the working process of the engine,the crankshaft will be affected by the inertial force generated by the reciprocating motion of the connecting rod and its own rotation,so it is easy to have the problems of bending,distortion and crack.At the same time,in the working process of the crankshaft,it is difficult to ensure the lubrication of its journal,and the journal part often has excessive wear.Therefore,in the production and processing technology of crankshaft,the material,hardness and accuracy of crankshaft shall meet the requirements,and reasonable and perfect repair methods shall be provided in the subsequent maintenance work.This paper analyzes the machining and repair methods of engine crankshaft.
