3 What is a Crankshaft?
A crankshaft is a mechanical part that transforms the reciprocating movement of the piston into rotational motion and turns the vehicle wheels. It is connected to the piston through a connecting rod.
The main function of the crankshaft is to transform the piston’s linear motion into rotary motion and turns the vehicle wheels. It works according to the upward and downward movement of the piston.
Without a crank, a reciprocating engine can’t deliver the piston’s reciprocating motion to the drive shaft. In simple words, a reciprocating engine can’t move a vehicle without a crankshaft.
3 中文解释
曲轴是发动机中最重要的部件。它承受连杆传来的力,并将其转变为转矩通过曲轴输出并驱动发动机上其他附件工作。曲轴受到旋转质量的离心力、周期变化的气体惯性力和往复惯性力的共同作用,使曲轴承受弯曲扭转载荷的作用。因此要求曲轴有足够的强度和刚度,轴颈表面需耐磨、工作均匀、平衡性好。
4 感想体会
Crankshaft,奇怪的轴,估计当时发明Crankshaft的工程师也没想好该七个什么样的名字,只能笼统的叫她“奇怪的轴”。
中文将其翻译为“曲轴”,其实也不是特别准确,曲应该指的是曲率连续变化,而曲轴则是瞬变,Crankshaft 翻译为“弯折轴”更形象一点。
