Design Of Swing Movable Teeth Transmission And Study On Two Teeth Difference Movable Teeth Transmission

Swing movable teeth transmission, which is used to transmit rotary motion and power between two shafts with same axis, is a new type of small teeth difference planetary drive. With a vast application vista, it has many advantages such as close structure, large range transmission ratio, strong load capacity and high transmission efficiency. But the structure of swing movable teeth transmission is complex, the structure parameter's influence upon transmission performance isn't easy to find directly. The contact between driving cam and swing movable teeth is line contact. The relation of swing drive teeth and internal gear is line contact also. So the contact pressure is very high and agglutination is easy to appear. Therefore, it is important to study the relationship between all structure parameters and movement parameters, and the research of the condition of lubrication of swing movable teeth transmission is necessary. In this paper, the swing movable teeth transmission is the main research object, and the two teeth difference movable teeth transmission is studied also.The movement of swing movable teeth transmission is analyzed, the equation of the tooth profile of internal gear, the formulas of relative angle speed and relative angle acceleration of swing movable teeth are obtained by using reverse method and the theorem of three centers. Then simulation technology is used in analyzing the swing movable transmission by visual basic language. The relationship between all structure parameters and movement parameters is discussed, and the affection for movement of swing movable teeth transmission is also discussed here.
