以CYJ10－3－37HB型抽油机为例，计算了其悬点运动参数，并给出了与简化为简谐运动和曲柄滑块机构运动的对比曲线；分析表明，悬点的上、下死点位置不是常规认为的180°和360°（或0°）曲柄转角，因而按常规计算时悬点位移将出现负值。

In the transmission mechanism of optional drive ratio worm crank pin,the circular pitch of annulus worm changes from the function of optional drive ratio.When the annulus worm tums equably,the roll-pin crank brings shift tuming through joggling,and it can applly to dumping and turning mechanism of ladle.

变传动比蜗杆曲柄销式传动机构，其环面蜗杆的齿距是依变传动比的函数关系变化的，当环面蜗杆匀速转动时，通过啮合使滚销式曲柄产生预期的变速转动，可应用于铸造生产的铁水浇包的倾转机构。

The compressor is with else crank connecting instrument ,OAD and the composition mould style fixs the necessary demand on the basis of the motorcycle in home and abroad,Consider to exchange and the current demand,Fix that the crank annuls that the use trundles the needle with maintains module KZK and a piston to annul in the way of KBK mould.

1连杆用滚针和保持架组件主要用于发动机，压缩机和其它曲柄连杆机构上，外形尺寸和结构型式的确定根据国内外摩托车的配套要求，考虑到互换和通用的要求，确定了曲柄销用滚针和保持架组件KZK和活塞销用KBK型。

Then the numerical simulation is developed with the above dynamic model. The effects of the clearance on the dynamic characteristics are studied in detail. The influence of factors such as clearance size, driving speed, stiffness, coefficient of viscous damping of contact surface, and the gravity are discussed and the quantitative results are given.

利用本文建立的动力学模型对含间隙三球销移动副的曲柄滑块机构进行了动力学数值仿真，研究了运动副间隙对机构的运动和受力状况的影响，考察了间隙大小、曲柄转速、接触刚度、阻尼、外力矩等对机构动态特性的影响规律，给出了定量结果。
