椭圆齿轮是一种用途广泛的传动零件,利用它可以实现变角速运动。但它是一种非圆齿轮,制造比较困难,特别在偏心率(即椭圆焦距与长轴之比)较大、精度要求较高的情况下,一般都需采用专用机床(如数控插齿机等)加工,因此使它的推广应用受到了一定限制。最近我厂加工了一种大偏心的椭 Elliptical gears are a versatile drive component that allows variable angular motion. However, it is a non-circular gear, which is difficult to manufacture. Especially in the case of large eccentricity (that is, the ratio of the elliptical focal length to the major axis) and the high precision requirements, it is generally required to use a special machine tool Etc.) processing, so its promotion and application has been subject to certain restrictions. Recently, I plant a large eccentric elliptical
