Effect of speed ratio on textures transformation in cross shear rolled high purity aluminum foils;

The effect of speed ratio on machine efficiency;

The effect of speed ratio on the texture of non-oriented cold rolled low silicon steel sheet was investigated after cross shear rolling at different speed ratios.

In view of the poor generality and the difficulty in controlling clamping force and gear ratio at will of mechanical-hydraulic control system,an electro-hydraulic control system for metal V-belt continuously variable transmissions(CVT) is brought forward in this paper.

It is the 2nd problem of conjugate surface that solve the bearing contact of gear and the gear ratio relation under given position with two known surfaces.

The speed-ratio curve of double-action parallel indexing cam mechanism has special property in shape,which makes it is not available from present transmission function,but designed purposely.

For double-action parallel indexing cam mechanism,the characteristics of its instantaneous center curve are determined by the mechanism’s speed-ratio.
