Devices For Conveying Motion By Means Of Endless Flexible Members
(AREA)
Abstract
Reducer-variator device characterized in that the variator is constituted by two trapezoidal pulleys with the possibility of varying the width of their throats, when a pulley plate is driven by a lever that causes an axial displacement; this movement received through the variator can be transmitted directly, by frontally engaging the two shafts of the reducer, since they are arranged axially, or through a reducer; this change occurs when the shaft that leaves the movement moves axially.

A mechanism of adjustable transmission, without steps, for example, a belt transmission, especially, for agricultural machines. (Machine-translation by Google Translate, not legally binding)
Improvements in the construction of drive groups for the support barreta of a venetian shutter. (Machine-translation by Google Translate, not legally binding)
