Reduction Gearbox: Definition, Requirements, Workings, And Advantages!

 A Reduction Gearbox, also known as a speed reducer, is a device that reduces the velocity of an input from a motor while simultaneously increasing the torque produced by the input. This machine converts the output shaft rotations of the basic engine into the number of propeller revolutions required to move the propeller. The reduction gearbox consists of teeth on wheels and gear trains that mesh to transfer energy from a drive shaft to a driven shaft while simultaneously decreasing the speed.

Depending on the complexity, a Reduction Gearbox can be as simple as a gear train connecting the motor and machinery. Regardless of complexity, the reduction is possible because the output gear has more teeth than the input gear. It permits the output gear to rotate more slowly than the input gear, reducing the speed and increasing torque. A reduction gearbox help regulate the speed of the input such that the output has the proper speed and torque.

What Is The Need Of A Reduction Gearbox? 

Let's take the example of a ship, for instance - 

While the effective operating of a propeller requires a relatively low rpm state, it is the primary requirement of a ship that the steam turbine performs at a comparatively high rpm range to achieve the desired efficiency. A reduction gearbox help achieve this, slowing down the high-speed spinning of the steam turbine to the low rpm level required by the propeller. 

The Arrangement Of Reduction Gearbox As Per Different Applications 

Gear reduction enhances torque while decreasing speed in many situations, it can also get utilized to increase speed while decreasing the torque. Wind turbine generators use gear reduction to increase the speed of the turbine blades from their low-generating speed to their high-generating speed. 

Reduction Gearbox Suppliers In India suggest that gearbox applications must get arranged in the opposite direction from those used in applications where speed gets reduced and increased torque.

The Advantages Of Reduction Gearbox - 

• There are more teeth in contact, which means that the machine can handle and transmit greater torque. It has a more consistent operation.

• More surface contact results in lower noise and softer rolling with barely little jumping are usual.

• Reduction gearboxes are more efficient and cause less damage due to their compact design and internal architecture.

• The bearings minimise the losses, that would occur if the shaft gets rubbed directly against the box. As a result, the gears operate more efficiently.
