ABSTRACT:
A mechanical transmission mechanism with rolling unit includes an input member, an output member and a transmission medium for transmitting a mechanical input. The input member includes a driving gear which is enveloped in a casing with a peripheral channel that is confined between a partial circumference of the driving gear and an inner face of the casing. The casing has two openings formed on both ends of the peripheral channel and connected respectively and tangentially to a pair of guide channels so as to form a guide path that extends between the input and output members. The transmission medium is a plurality of rolling bodies which are packed in the guide path and which are disposed alternatingly in juxtaposed lines along the guide path. Each of the rolling bodies is in rolling contact with adjacent rolling bodies. A line of rolling bodies matches the driving gear to enable each of the rolling bodies in the line to move rollingly along the guide path to drive rollingly the rolling bodies of an adjacent line and thus drive the output member when the driving gear is in operation.
