The rod-bearing cap attaches the connecting rod to the crankpin. 连杆轴瓦盖将连杆安装到曲轴销上。
As the crankshaft rotates, the crankpin swings in a circle around the shaft. 随着曲轴的转动，曲柄销绕主轴作圆周摆动。
The connecting rod carries the power thrusts from the piston to the crankpin. 连杆的作用是将活塞承受的压力传给连杆轴颈。
The S1-217 crankpin lathe of crankshaft is one of the important equipment. 2 17曲轴连杆颈车床是车削曲轴连杆颈主要设备之一。
The Load map and wearing maps of the crankshaft journals and crankpin are obtained under various operating conditions. 研究表明：气缸压力和转速升高后，曲柄销和主轴颈的磨损均呈现增加趋势。
