What is a Gearbox


What is a Gearbox

A gear is a rotating machine part featuring cut teeth or cogs, which is supposed to mesh with another toothed part in order to transmit torque. Gears are one of the most crucial parts of any motors and machine which help to increase the torque output by providing gear reduction and adjusting the direction of rotation. Two or more gears working together in tandem are called transmission or gearbox. Geared devices are more likely to change the speed, torque, direction of a power source.

How they work?
An electric or hydraulic motor is applied at one end of the gear box while on the other end the energy is converted into a low speed drive torque. Inside the box the materials used are of high endurance thus supporting huge strength needed. Can you think of the energy needed to handle the rubble of a cruise liner during maneuver? Or that of the container crane? Or even an underground digging machine?

Types of Gearboxes:

Helical Gearbox:

Helical gears and Helical Gearbox both have the capacity to conduct a smooth operation. The teeth on a helical gear cut at an angle to the face of the gear. So, during the process when two of the teeth start to engage, the contact is gradual- starting at one end of the tooth and maintaining contact as the gear rotates into full engagement. When it comes to transmissions, helical is the most commonly used gears and it even generates large amounts of thrust.

Helical gearbox unique point:

Its unique point is that it is fixed at an angle which, when in motion enables more interaction in the same direction. This gives constant contacting for a given period of time. Extruder helical gearbox is additionally utilized when torsion solidness should be utilized to its greatest potential and furthermore for low-commotion application. Applications include Steel, Rolling Mills, Conveyors, Elevators, Oil Industries.

Bevel Helical Gearbox:

Do you know the critical feature of this gearbox? It is a curved set of teeth which are located on it cone-shaped surface close to the rim of the unit. Bevel gearbox is also used to provide rotary motion between non-parallel shafts. They play their role in quarries in the mining industry, mixers, conveyors.

Worm Gearboxes:

Worm gearbox uses worm wheel that has a large diameter. The worm or screw meshes with the teeth on the peripheral area of the gearbox. The rotating motion of the worm gearbox causes the wheel to move similarly like that due to the screw-like movement. The setup is designed in such a way that setup can turn the gear, but the gear cannot turn the worm. The angle of the worm is shallow and as a result, the gear is used in conveyor systems for brake or emergency stop. These gearboxes are also used in pharmaceutical and packaging machines, Bottling plant conveyors, Machines for Food industry.

Planetary Gearbox:

The planetary gearbox is said to be ideal and also known for its endurance, accuracy and distinct functionality and is notable for its precision applications. Planetary gearbox increases the lifespan of your equipment and also optimizes its performance to its full potential. This gearbox comes in either a solid type of hollow format or with a variety of mounting options including a flange, foot or shaft. The usage of this gearbox differs as per industry type but, the bottom line is that the gearboxes are made to make the mechanical functioning easy in different industries.
