转动曲柄

Confirms the relation between speed fluctuation coefficient of the crankshaft and moment of inertia of the balance wheel.

确定曲柄速度波动系数与飞轮转动惯量的关系。

And it mainly studies the piston and connecting rod movement rule as well as crank link motion gear movement envelopment. This research does not consider the outside force and makes the crank to maintain the uniform speed rotation.

本课题以应用为目的，面向于企业实际产品，主要研究了在不考虑外力作用并使曲轴保持匀速转动的情况下，活塞和连杆的运动规律以及曲柄连杆机构的运动包络。

These,with two others below, formed the turning cross of the reaping－machine.

It is applied to sorts of locomotive engine , In course of revolving of Crank and Connecting Rod Mechanism, there are revolving of the crankshaft , swinging of the connecting rod and reciprocating motion, so its motion state is complex, and periodic unbalanced force, by a few components, is great.

曲柄连杆机构在高速运转过程中，有曲轴的转动、连杆的摆动及活塞的往复运动，其运动状态复杂，各个部件所产生的周期性不平衡惯性力大，是引起发动机振动的主要原因。

The connecting rod big-end embraces a loose eccentric, frictionally connected to the crank and permitted to turn through 180 degrees: see inset.

连接杆头支持着一个松散的摩擦杆，可以联络到曲柄以及被允许通过180度转动：详见插页。
