连杆是汽车活塞式发动机的主要传动件之一,它的作用是将活塞的直线运动转变为曲轴的旋转运动,并把作用在活塞组上的燃气压力传给曲轴,所以连杆除上下运动外,还左右摆动,做复杂的平面运动。连杆工作时主要承受气体压力和往复惯性力所产生的交变载荷,要求具有足够的疲劳强度和结构刚度。同时,由于连杆既是传动零件又是运动件,不能单靠加大连杆尺寸来提高其承载力,需要综合选用材料、结构设计、零件加工等来保证连杆的质量,所以连杆的
Connecting rod is one of the main transmission parts of automobile piston engine. Its function is to convert the linear motion of the piston into the rotational movement of the crankshaft, and transmit the gas pressure acting on the piston group to the crankshaft, so the connecting rod can move up and down In addition, it swings left and right to do complicated plane movements. Rod work mainly to withstand gas pressure and reciprocating inertia force generated by the alternating load, requires adequate fatigue strength and structural rigidity. At the same time, since the connecting rod is both a moving part and a moving part, the connecting rod can not be increased in bearing capacity simply by increasing the size of the connecting rod, and the quality of the connecting rod needs to be ensured by comprehensively selecting materials, structural design, parts processing and the like
