Friction roller drive 6




Input: the pink roller rotating clockwise. Output: the green roller.

The blue crank can idly rotate on the pink shaft.

The yellow roller idly rotate on axle of the orange slider.

The friction forces at contact places are created automatically.

The transmission is possible if tg((a+b)/2) is less than m. a is angle CAB, b is angle CBA m is friction coefficient of roller materials (the smaller one)

Weights of the blue crank, the orange slider and the yellow roller create initial friction forces at the contact places.

No transmission if the pink roller rotates counterclockwise.
