A gearbox is a mechanical gadget utilized to increase the result torque or change the velocity (RPM) of a motor. The motor’s shaft is usually mounted on one end of the gearbox and through the inner configuration of gears of a gearbox, provides a given output torque and speed determined by the gear ratio.
Physical Properties
The physical elements of gearboxes vary from one gearbox type to some other, as well as differences between manufacturers. Many gearboxes are constructed from steel materials such as iron, gearbox construction aluminium and brass. Unlike additional gearbox types, spur gearboxes may also be produced with plastics such as for example polycarbonate or nylon. Apart from the raw materials utilized, the orientation of the apparatus teeth play a significant role in the entire efficiency, torque and velocity of the machine. Straight gear tooth gearboxes are typically found in low-quickness applications. These gearboxes could be noisy, and could have lower overall efficiency. Helical gearboxes are usually used in high-rate applications. These gearboxes are quieter in operation than straight gear the teeth gearboxes, which may enhance their overall efficiency.
Types of Gearboxes
There are many types of gearboxes produced throughout the world. Among the main differences between individual gearboxes is their functionality features. Choosing from the many gearbox types is software dependent. Gearboxes can be found in many sizes, ratios, efficiencies and backlash characteristics. All of these design elements will affect the functionality and price of the gearbox. There are many types of gearboxes which are the following:
Bevel Gearbox
Bevel Gears
There are two types of bevel gearboxes such as either straight or spiral teeth gears. Directly bevel gears have directly and tapered the teeth and are used in applications requiring slow speeds. Spiral bevel gears possess curved and oblique the teeth and are used in applications needing high-overall performance, high speed applications.
Physical Properties
Bevel gears are usually made of cast iron, aluminum alloy or other steel materials but vary between producers.
Note: Gears created from steel materials could be noisy when coming into connection with other gears and in addition make them prone to wear.
Applications of Bevel Gears
Bevel gearboxes make use of bevel gears and so are mainly used in right angle applications with the shafts in a perpendicular arrangement.
• Print Press
• Power Plants
• Automobiles
• Steel Plants
• Hand Drills
• Differential Drives
Advantages of Bevel Gears
• Right angle configuration
• Durable
Disadvantages of Bevel Gears
• Axes must be able to support forces
• Poorly cut the 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 provides for a smooth and silent operation. Gearboxes using helical gears are applicable in high horsepower and effective applications.
Physical Properties
Helical gears are usually made of cast iron, aluminum allow or iron material but may vary depending on the manufacturer.
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
Advantages 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 the teeth mounted on a parallel shaft. The noise degree of spur gears is usually relatively high because of colliding teeth of the gears which will make spur gear teeth susceptible to put on. Spur gears come in a range of sizes and gear ratios to meet applications requiring a particular speed or torque result.
Physical Properties
Spur gears are typically constructed from metals such as for example metal or brass, and plastics such as nylon or polycarbonate. The materials used to construct spur gears may vary depending on the maker.
Note: Gears created from steel materials could be noisy when coming into contact with other gears and in addition make them susceptible to wear.
Applications of Spur Gears
Spurs gears are used in applications requiring a reduction 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
• Susceptible to wear
Worm Gearbox
Worm Gears
Worm gears can withstand high shock loads, lower in sound level and maintenance-free but are less efficient than additional gear types. Worm gears can be used in right angle configuration. The worm gearbox configuration enables the worm to turn the gear with ease; however, the gear cannot change the worm. Preventing the gear to move the worm can be utilized as a braking system. When the worm gearbox is not active, it is in a locked position.
