Description
A quarter-turn gearbox is a mechanical device designed to provide a 90-degree rotation (or a quarter turn) to an input shaft, converting rotary motion into a different angular direction. These gearboxes are commonly used in various industrial applications, such as valve automation, where a quarter-turn motion is required to control the flow of fluids or gases. They are essential components in systems where precise and controlled rotational movement is necessary. Quarter-turn gearboxes come in different types, such as worm gear, bevel gear, or spur gear configurations, each suited for specific applications based on their design and efficiency requirements.
