ABSTRACT:
The present invention provides a mechanism for converting rotary motion into translation motion, the mechanism comprising a first member which is rotated and which is constituted by a cylinder having a helical spring threaded thereover and fixed thereto at at least one point, and a second member for being driven in translation by the first member and including slots for co-operating with the thread constituted by the spring. This transmission system is intended, in particular, for use in relatively rudimentary mechanisms of the type used in agricultural machinery.
