Rotary-linear transmission

摘要

The transmission (2) has a bidirectional cam (4) rotating around a rotating axle (O) at an angle lesser than 90 degree, and another bidirectional cam (8) rotating around a pivot (ohm) at an angle lesser than 90 degree. The pivot is coupled to a body moving in translation direction. The cam (4) has a cam surface provided with a toothed profile (12) engaging with toothed profile (14) of cam surface of the cam (8).
