VDI 2125:2016-04

The standard describes the procedures to determine the optimal four joint transmission for converting pushing movements into rotary motion. The thrust arm (or thrust handle), thrust loop and cross push crank handle are covered. It mainly describes the quality of the movement transfer, meaning optimal and acceptable solutions with regard to the transmission´s quality. Applications can be found, for example, for linear actuators, thrust cylinders, electrically driven screws, lifts and variators for road construction and earth-moving machines, power gears for agricultural machinery.
