What is a Gearbox? A gearbox is a mechanical device utilized to increase the output torque or change the speed RPM of a motor. The motor's shaft is attached 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 physical components of gearboxes vary from one gearbox type to another, as well as differences between manufacturers. Most gearboxes are constructed from steel materials such as iron, aluminum and brass. Unlike other gearbox types, spur gearboxes can also be made with plastics such as polycarbonate or nylon.

Other than the raw materials used, the orientation of the gear teeth play a major role in the overall efficiency, torque and speed of the system. Straight gear teeth gearboxes are typically used in low-speed applications. These gearboxes can be noisy, and may have lower overall efficiency. Helical gearboxes are typically used in high-speed applications.
These gearboxes are quieter in operation than straight gear teeth gearboxes, which may improve their overall efficiency. There are many types of gearboxes manufactured throughout the world.
One of the main differences between individual gearboxes is their performance characteristics. Choosing from the various gearbox types is application dependent.
Gearboxes are available in many sizes, ratios, efficiencies and backlash characteristics. All of these design factors will affect the performance and cost of the gearbox. There are several types of gearboxes which are listed below:. Bevel Gears There are two types of bevel gearboxes which include either straight or spiral teeth gears.
Straight bevel gears have straight and tapered teeth and are used in applications requiring slow speeds. Spiral bevel gears have curved and oblique teeth and are used in applications requiring high-performance, high speed applications. Physical Properties Bevel gears are typically constructed from cast iron, aluminum alloy or other steel materials but vary between manufacturers.
Note: Gears made from steel materials can be noisy when coming into contact with other gears and also make them prone to wear. Applications of Bevel Gears Bevel gearboxes use bevel gears and are mainly used in right angle applications with the shafts in a perpendicular arrangement.
Helical Gears Helical gears are cut at angles which allow for gradual contact between each of the helical gear teeth. This type of innovation provides for a smooth and quiet operation. Gearboxes using helical gears are applicable in high horsepower and efficient applications. Physical Properties Helical gears are typically constructed from cast iron, aluminum allow or iron material but may vary depending on the manufacturer.
Applications of Helical Gears Helical gears are widely used in applications which require efficiency and high horsepower.A Gear Box is an assembly consisting of various gears, synchronizing sleeves and gear-shifting mechanism fitted inside a metal housing. Of which, the gearbox is an integral part. These components include the clutch, gearbox, couplings, propeller shaft, axle shafts, and differential. The gear ratio is the ratio between the input and output gears. The driving gear and driven gears in a gear box define the gear ratios.
The input gears get the drive from the engine and they rotate the output gears which, in turn, drive the wheels. The ratio of the number of rotations of output gear to the number of rotations of input gear is called Gear Ratio. For e. Following is a chart of gear ratio found in an MUV 's gear box. The gear ratios vary from vehicle to vehicle.

In trucks, the gear ratios are typically higher than cars as they have to carry the heavy load. A gear box contains gears of different sizes. In a gear box, the first gear is biggest in size and provides maximum torque output while producing minimum speed. Hence, it is used when climbing slopes.
All the gears between 1 st and last gear vary in size; in a decreasing ratio. Thus, it provides a varying combination in terms of pulling ability and speed. So, the vehicle could be driven smoothly without any drop in its acceleration.
The gear box basically improves the vehicle's driveability in all conditions. In contrast, the last gear or the top gear, at times an Overdrive, is smallest in size. However, it provides minimum traction but maximum speed. A gearbox with an Overdrive means its output is higher than its input that connects to the engine. In other words, the overdrive gear rotates faster than the engine speed. Thus, it provides higher speed and better efficiency as the engine runs at a lower rpm in relation to vehicle speed.
In some advanced designs, there are more than one 'Overdrive' gears; usually two. Thus, Dual Overdrive aka 'Double Top' provides even higher speed and better efficiency in a vehicle.
The input gears are fixed on the countershaft making it a single unit. 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.
You need both the speed as well as the traction while driving an automobile. The gears in the gearbox help you choose either of them depending on the driving conditions. The lower gear i. The number of gears in the gearbox provides the perfect combination of traction and speed.The 2nd Generation CH Series Planetary Winch family is designed to provide excellent performance along with long service life.
