A bevel gearbox is a type of gear system that allows for the transmission of power between intersecting shafts, typically at a right angle. These gearboxes use bevel gears, which have conically shaped teeth, to change the direction of the drive in mechanical systems.
When it comes to mounting on valves, bevel gearboxes are specifically designed to facilitate the manual or motorized operation of linear valves, such as gate, globe, and sluice/slide gate valves. These gearboxes are mounted on the valve stem and help in converting the rotational motion from the handwheel or motor into the linear motion needed to open or close the valve. They are engineered to handle the torque and thrust requirements of the valve operation, ensuring smooth and efficient performance.
