ADJUSTABLE REDUCTION GEAR

摘要

The invention relates to the field of mechanical engineering and concerns reduction gears capable of changing gear ratio (mechanical stepped change-speed gearboxes). The aim of the invention is to provide the possibility of changing the gear ratio without power loss, and also to reduce impulse loads on the structural components, thus increasing the operating life of the change-speed gearbox and enhancing the reliability and durability thereof. The proposed mechanism is capable of operating smoothly with high reliability and durability, and the change of gear ratio takes place without power loss. As a result, the inevitable wear on the contact surfaces in each brake assembly is compensated for, and the force of the compressed elastic power link remains approximately the same during the entire time that the proposed reduction gear is in use.
