具有变速传动特性的椭圆齿轮机构串联曲柄滑块机构能够明显改变传统压力机滑块的运动特性。将滑块最大速度和工作行程回程比作为衡量滑块运动性能的量化指标。椭圆齿轮的偏心率对滑块最大速度和工作行程回程比具有明显的影响,曲柄与椭圆齿轮长轴之间的安装相位角对滑块最大速度和工作行程回程比有较大影响,曲柄和连杆长度比对滑块最大速度以及工作行程回程比基本无影响。通过变换安装相位角的方式可以使同一台压力机满足各类冲压工艺的不同要求。

The kinematics characteristic of a press slide can be changed obviously by the ellipse gears and crank gear in series.The maximum velocity of the slide and the ratio between working stroke and idle stroke are the important parameters for the slide of a press.The eccentricity of the ellipse gear influences the parameters obviously.The fixing angle between the crank and the long axis of ellipse gear also affects the parameters obviously.The length ratio of crank and connecting rod almost has no effects to those parameters.It can make the press suit the different stamping technology through changing the fixing angle between the crank and the long axis of ellipse gear.
