Introduction of industrial gearbox

The industrial gearbox is a power transmission device that receives mechanical power from the generator source and transfers it to the consumer part with a different torque and rotational speed. Since the meaning of Gearbox in Farsi language is gear box, many people also know this device as gear box. These devices carry out the process of power transmission based on the user’s needs and continuously. The importance of using gearboxes is determined when there is a need to display the input power of the device in a different way according to the work requirement. In such a situation, the use of this device can help the continuous transfer of this power according to the user’s needs.

Also, these devices play two important roles in the mechanism of different systems, and accordingly, they can be placed in two categories of reducing and increasing gearboxes. Gearbox reducer is an interface between the driving part and the moving part of the system, which provides the desired speed based on working conditions. Most of the gearboxes are of this model, which are supplied with different types. The booster gearbox, also known as the high-speed gearbox, is used in some industries where torque and speed changes are needed to achieve a high speed along with a low torque. These devices are used in refinery industries and wind turbine design.

The reliable site Premium-transmission has made a simple definition of industrial gearbox; An industrial gearbox is a system in which mechanical energy is transferred from one device to another and is used to increase torque and decrease speed.
