What's in a gearbox?
A gearbox is always a fully integrated mechanical component consisting of a series of mating gears contained in a housing with shafts and bearings (to support and resolve loads) and in many cases a flange for motor mounting.
What Is Gearbox And Its Function?
The gearbox is a mechanical device used to increase the output torque or to change the speed (RPM) of a motor. The shaft of the motor is connected to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio.
Where Are Gearboxes Used?
Gearboxes are used in many applications including machine tools, industrial equipment, conveyors, and really any rotary motion power transmission application that requires changes to torque and speed requirements.
Why Gearbox Is Used With Motor?
A gearbox can be added to a motor to drastically decrease speed and/or increase torque.
How Does Gearbox Work?
It drives the individual gears on the main shaft, which rotate freely on the bearings. Thus, the gearbox passes the drive to the wheels depending upon the gear which engages on the main shaft. When you push the shifter-sleeve towards the desired gear, that gear locks onto the main shaft and rotates it.
What Is The Difference Between A Gearbox And A Transmission?
The difference between gearbox and transmission is that, while these two are two separated units, the transmission refers to the whole drivetrain which includes gearbox, clutch, prop shaft, final drive shafts, and differential.
What Is Gearbox Ratio?
Does Gearbox Increase Speed?
Gearboxes reduce speed and increase torque. Whilst there are occasionally gearboxes that will increase speed and reduce torque, in the vast majority of cases, a gearbox will be used to reduce the shaft speed of a motor and increase the torque.
How Do You Calculate Gearbox Kw？
Motor power = torque ÷ 9550 × Rated power’s motor input speed /Ratio /service factor.

What is Gearbox？
The gearbox is a mechanical device used to increase the output torque or to change the speed (RPM) of a motor. The shaft of the motor is connected to one end of the gearbox and through the internal configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio.
The most basic definition of a gearbox is that it is a contained gear train, or a mechanical unit or component consisting of a series of integrated gears within a housing. In fact, the name itself defines what it is a box containing gears. In the most basic sense, a gearbox functions like any system of gears; it alters torque and speed between a driving device like a motor and a load.
The gears within a transmission can be one of several types, from bevel gears and spiral bevel gears to worm gears and others such as planetary gears. The gears are mounted on shafts that are carried by roller bearings and rotate about them. The gearbox is a mechanical method of transferring energy from one device to another and is used to increase the torque while reducing the speed at the same time.
Gearboxes are used in many applications including machine tools, industrial equipment, conveyor belts, and virtually any rotary motion power transmission application that requires changes in torque and speed requirements.

How it works?
An electric or hydraulic motor is applied to one end of the gearbox, while the energy is converted into low-speed drive torque at the other end. Inside the box, the materials used have a long service life, which supports enormous strength.

Types of Gearboxes？
Gears generally rely on rotation to achieve mechanism motion, so each gear will have a gear axis. According to the motion of the gear axis, the gears can be divided into two categories: fixed shaft gear (representing the design of duplex gear gearbox) and turnover gear (representing the design of planetary gear gearbox)
Duplex gear are mainly utilized where any backlash is unwanted or can be harmful, to maintain repeated high precision positioning in both directions, to prevent impulse loaded damage, and when the contact flanks are alternating. Common applications of duplex gear gearboxes include: rotary and tilting tables, milling machines, and presses.
