| 1. | 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。
|
| 2. | 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。
|
| 3. | The cap and rod have bearings which permit the crankpin to rotate freely within the rod .
轴瓦盖和连杆中有轴瓦，它允许连杆内的曲柄锁自由地转动。
|
| 4. | Smooth and finish the crankpin to roundness
把曲柄销磨光并精加工到正圆。
|
| 5. | Crankpin bearing lubrication
曲柄销承润滑
|
| 6. | 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。
|
| 7. | Wearing of crankshaft journals and crankpin is one of the most key indexes for evaluating the working life of internal combustion engine
摘要内燃机曲轴轴颈的磨损量是衡量内燃机寿命的一个重要指标。
|
| 8. | In the simulation , the mpc technique of msc . nastran is used to simulate the mechanical behavior of contact between the interfaces of piston pin and bearing of small end , crankpin and big end bearing , connecting rod body and bearing cap ; also constraints are applied to the connecting rod reasonably
分析中采用了patran中的多点约束( mpc )技术，有效地模拟了活塞销与小头孔内表面、曲柄销与大头孔内表面以及连杆体与大头盖接触面的力学接触状态，并对连杆进行合理的约束。
