轴承

The piston is attached to the top of a connecting rod by a pin,called a piston pin or wrist pin.the bottom of the connecting rod is attached to the crankshaft.the connecting rod transmits the up-and-down motion of the piston to the crankshaft,which changes it into rotary motion.the connecting rod is mounted on the crankshaft with large bearings called rod bearings.

这个活塞被一个叫活塞销或轴颈销的销子连接在连杆的上部。连杆的底部被连接在曲轴上。连杆把活塞的上下运动传递给曲轴转变成旋转运动。连杆通过一个大的叫做杆轴承的轴承（其实就是滑动轴承，分成两个半圆轴瓦）安装在曲轴上。
