sprocket drive

The harmonic chain drive has a periodically varied theoretical chain length during its operation. This paper analyzes the changes in theoretical chain length when wave generator is at different positions, and indicates their effect on driven sprocket angular speed and transmission ratio.

谐波链传动在传动过程中所需链条的理论长度呈周期性变化，分析了传动中波发生器处在不同位置时链条理论长度的变化情况，并指出了这种变化对从动链轮角速度及传动比的影响。

Many accidents occur on the original rise-fall vehicles of the roast device in RH vacuum chamber, these vehicles used gear-rack drive or sprocket-chain drive. But better effect can be brought by using hydraulic rod-chain drive.

原RH真空室烘烤装置升降小车采用齿轮齿条传动方式或链轮链条传动方式，都曾多次发生事故，改用液压推杆&链条传动方式后使用效果很好。

Comparative study show that the drive system using the nonstandard sprocket is improved in many ways such as chain tension, contact force and friction force between chain and transmission components, tension force provided by tensioner, angular velocity of camshaft sprocket.
