A gearbox is a mechanical device utilized to boost the output torque or change the speed (RPM) of a engine. The motor’s shaft is usually mounted on one end of the gearbox and through the inner configuration of gears of a gearbox, offers a given result torque and speed dependant on the gear ratio.
Physical Properties
The physical elements of gearbox construction gearboxes vary from one gearbox type to another, as well as distinctions between manufacturers. Many gearboxes are made of steel materials such as iron, aluminum and brass. Unlike additional gearbox types, spur gearboxes may also be produced with plastics such as for example polycarbonate or nylon. Other than the raw materials used, the orientation of the apparatus teeth play a significant role in the entire efficiency, torque and acceleration of the system. Straight gear tooth gearboxes are typically used in low-speed applications. These gearboxes can be noisy, and could have lower overall effectiveness. Helical gearboxes are typically used in high-rate applications. These gearboxes are quieter in operation than straight gear tooth gearboxes, which may improve their overall efficiency.
Types of Gearboxes
There are plenty of types of gearboxes manufactured throughout the world. One of the main distinctions between person gearboxes is their overall performance features. Choosing from the many gearbox types is software dependent. Gearboxes can be found in many sizes, ratios, efficiencies and backlash characteristics. Most of these design elements will affect the efficiency and cost of the gearbox. There are several types of gearboxes which are the following:
Bevel Gearbox
Bevel Gears
There are two types of bevel gearboxes which include either straight or spiral teeth gears. Directly bevel gears have straight and tapered tooth and are used in applications requiring sluggish speeds. Spiral 
bevel gears have got curved and oblique tooth and are found in applications requiring high-functionality, high speed applications.
Physical Properties
Bevel gears are usually constructed from cast iron, aluminium alloy or other steel materials but vary between manufacturers.
Note: Gears made from steel materials can be noisy when getting into contact with other gears and also make them prone to wear.
Applications of Bevel Gears
Bevel gearboxes use bevel gears and are mainly utilized in right angle applications with the shafts in a perpendicular set up.
• Print Press
• Power Plants
• Automobiles
• Steel Plants
• Hand Drills
• Differential Drives
Benefits of Bevel Gears
• Right angle configuration
• Durable
Disadvantages of Bevel Gears
• Axes must be able to support forces
• Poorly cut teeth may lead to excessive vibration and sound during operation
Helical Gearbox
Helical Gears
Helical gears are cut at angles which enable gradual contact between each one of the helical gear teeth. This kind of innovation offers a smooth and peaceful procedure. Gearboxes using helical gears are applicable in high horsepower and efficient applications.
Physical Properties
Helical gears are typically made of cast iron, aluminum allow or iron materials but can vary greatly depending on the maker.
Note: Gears made from steel materials can be noisy when coming into contact with other gears and in addition make them susceptible to wear.
Applications of Helical Gears
Helical gears are widely used in applications which require efficiency and high horsepower.
• Oil Industry
• Blowers
• Food and Labeling
• Cutters
• Elevators
Benefits of Helical Gears
• Could be meshed in parallel or cross orientation
• Smooth and quiet operation
• Efficient
• High horsepower
Disadvantages of Helical Gears
• Resultant thrust along axis of gear
• Additives to lubrication
Spur Gearbox
Spur Gears
Spur gears are made with straight teeth mounted on a parallel shaft. The noise degree of spur gears is certainly relatively high because of colliding tooth of the gears which will make spur gear teeth prone to wear. Spur gears can be found in a range of sizes and equipment ratios to meet up applications requiring a particular speed or torque output.
Physical Properties
Spur gears are usually constructed from metals such as for example metal or brass, and plastics such as nylon or polycarbonate. The material used to construct spur gears can vary greatly depending on the manufacturer.
Note: Gears made from steel materials can be noisy when coming into connection with other gears and in addition make them prone to wear.
Applications of Spur Gears
Spurs gears are used in applications requiring a decrease in speed with high result torque.
• Cut-to-Length
• Packaging
• Speed Control
• Construction
• Power Plants
Benefits of Spur Gears
• Cost-effective
• High gear ratios
• Compact
• High torque output
Disadvantages of Spur Gears
• Noisy
• Prone to wear
Worm Gearbox
Worm Gears
Worm gears can withstand high shock loads, lower in noise level and maintenance-free but are less efficient than additional gear types. Worm gears can be utilized in right angle configuration. The worm gearbox configuration allows the worm to turn the gear with ease; however, the apparatus cannot convert the worm. Preventing the gear to go the worm can be utilized as a braking program. When the worm gearbox is not active, it is held in a locked position.
