Question: 1 / 400

What is the function of a gearbox?

To regulate temperature of the machinery

To change speed and torque between motor and equipment

The function of a gearbox is primarily to change speed and torque between a motor and the equipment it drives. Gearboxes are mechanical devices consisting of gears that allow for the reduction or increase of speed while simultaneously adjusting the torque output. This is essential in many machinery applications because different equipment operates most efficiently at specific speeds and torque levels. By altering these parameters, gearboxes ensure that motors and machinery can work together harmoniously, allowing for optimal performance and prevention of damage.

For instance, in scenarios where high torque is needed at low speeds, a gearbox can provide a mechanical advantage by reducing speed while increasing torque, which is especially important for heavy-duty applications such as conveyor systems or in construction and manufacturing equipment.
