To solve the low-frequency resonance problem of a non-sinusoidal oscillation system driven by oval gears in continuous casting,the dynamic model of the oscillation system was built up.

The mechanism is constituted by three parts, they are oval gear transmission division, planetary gear transmissi on division and plant the arm.

Dynamics analysis on non-sinusoidal vibration system of crystallization utensil driven by elliptical gears;

Simulation of the shaping machine of elliptical gear;

Elasticity hydromechanical lubrication for elliptical gear transamination;

Kinematic characteristic of press with ellipse gear transmitting;

The graphic method of designing ellipse gears with a universal CAD software;

The working principle of an ellipse gear drive was described in this paper Then,its application to packaging machinery was analysized and discussed Finally,its manufacturing features based on a numerically_controlled machine tool were simply introduce

It is introduced the principle of traverse mechanism applied elliptic gears in automatic silk reeling machine.

The separating planting mechanism with planetary elliptic gears of high performance rice transplanter made in Japan could not meet the agronomic demand in South China.

With a Elliptic Gears Mechanism serving as a front-position mechanism for the sheave wheel mechanism.
