DESIGN OF BEVEL GEAR PAIR FOR GATE VALVE

Avishkar Bhoskar, Sanjay Yadav

Abstract: Bevel gears are widely used in the application where requirement is to transmit the power in 90 degrees. Where shafts intersect each other, the basic need is fulfilled by the bevel gear pair only. These gears are used in many applications and the most common application is differential use in automotives. This paper mainly focuses on the design and mathematical modeling of the bevel gear pair used in gate valve unit. Gate valve is valve which opens by lifting a round or rectangular gate/wedge out of the path of the fluid. To operate this gate valve the main component used is bevel gear pair. It is needed to check the maximum torque transmission capacity of gear pair so as to know its limits. Involute gear is used in this application. Gate valves are actuated by a threaded stem which connects the actuator (e.g. handwheel or motor) to the gate.

Keywords: Involute Bevel Gear, Gate Valve.
