DESIGN AND DEVELOPMENT OF TWO SPEED GEAR BOX FOR AGRO MACHINERY

Abstract: Conventional gearboxes are capable of varying a given input speed. It is achieved by meshing of gears in various gear ratios. The torque values are different during different gear ratios. Hybrid gearboxes are capable of transmitting various torque levels at the same gear ratio. They have a high torque producing capacity compared to a conventional gearbox. These gearboxes have provisions for several inputs and several outputs, unlike one input and one output of a conventional gearbox. It allows the choice of varied speeds to the inputs. These gearboxes can be used in a lot of practical applications. As they have very high loading capacities, they can be used in off-road, commercial vehicles, military vehicles and other specialty vehicles. They can also be used in cranes, pumps, tractors, lawn mowers etc. Its most important application is that it can be used in a hybrid car.
