Abstract
A variable speed ratio transmission comprises a support structure, an input member, an output member and a plurality of planet wheels which are supported rotatably on the support structure and which receive the movement from the input member. Each of the planet wheels comprises a connecting rod which is rotatably connected thereto in the region of a first end thereof and which supports at an opposite end thereof a unidirectional connection wheel which entrains in rotation the output member. The transmission further comprises a variation device for the spacing between the pivot axis of the connecting rods and a respective rotation axis of the planet wheels.
Claims17
A variable speed ratio transmission (100) comprising:
- a support structure (10);
- an input member (1) of a rotational movement about a main axis of rotation (X) which is rotatably connected to the support structure (10);
- an output member (2) of the rotational movement;
- a plurality of planet wheels (3) which are arranged peripherally with respect to the main rotation axis (X) and which are supported rotatably on the support structure (10) and which receive the movement from the input member (1);
- each of said planet wheels (3) comprises a connecting rod (4) which is rotatably connected thereto in the region of a first end (41) thereof and which supports at an opposite end (42) thereof a connection wheel (5) which is rotatably connected in a unidirectional manner to the end so as to entrain in rotation the output member (2) during a rotational movement of the input member (1) about the main rotation axis (X),
- the variable speed ratio transmission (100) further comprises a variation device (6) for a spacing (d) between a pivot axis (P) of the connecting rods (4) on the planet wheels (3) and a respective rotation axis (X′) of the planet wheels (3).
