Mechanism of transformation of rocking motion into rotational motion

According to Leonardo Da Vinci's sketch, a mechanism for converting rocking motion into rotational motion has been developed. Taking into account the increasing transmission properties of the mechanism, which corresponds to a gain in speed for the movement of the output link (working body), it is a mistake to believe that the mechanism is suitable for a lifting and transport machine. In jacks and lifts, a mechanism with a lowering gear function is usually used when there is a gain in power at the output. A fan is used as the working body of the proposed machine. At the same time, a 3D model of the screw was borrowed Small Electric Fan . Another feature of the presented design is the execution of the input link in the form of a pendulum.
