Abstract


The paper wants to present an innovative device with a role in reducing the reaction moment, which occurs under normal working conditions in machines that perform rotational movement around their own axis. Starting from the third principle of dynamics, also called the principle of action and reaction, a device was designed to decrease the reaction moment. The device presented in the article consists of a mechanism with chain transmission made up of 12 identical chain wheels placed according to a certain geometric scheme. The chain is driven in translational motion with the help of an electric motor by means of a gear of two cylindrical gears with inclined teeth. One of these gears is mounted on the rotor axis of this motor, and the other gear is mounted on the axis of one of the 12 sprockets. The structure that supports the bearings of the chain wheels is rigidly connected to the stator of the motor, forming a common body with it so as to make it possible to rotate it also around the same axis of the rotor. During operation, the reaction moment produced by the entire system will be compensated and greatly reduced. To highlight the effect of the chain as best as possible, weights placed evenly on the chain are mounted along the entire length of the chain.
