A gearbox is a mechanical device utilized to raise the result torque or alter the swiftness (RPM) of a electric motor. The motor’s shaft is usually attached to 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 change from one gearbox type to some other, as well as distinctions between manufacturers. Most gearboxes are made of steel materials such as iron, aluminum and brass. Unlike various other gearbox types, spur gearboxes may also be made with plastics such as for example polycarbonate or nylon. Apart from the raw materials used, the orientation of the apparatus teeth play a significant role in the entire efficiency, torque and rate of the system. Straight gear the teeth gearboxes are typically used in low-velocity applications. These gearboxes could be noisy, and may have lower overall performance. Helical gearboxes are typically used in high-acceleration applications. These gearboxes are quieter in operation than straight gear tooth gearboxes, which may enhance their overall efficiency.
Types of Gearboxes
There are various types of gearboxes manufactured throughout the world. Among the main differences between person gearboxes is their performance characteristics. Choosing from the various gearbox types is software dependent. Gearboxes can be found in many sizes, ratios, efficiencies and backlash characteristics. Most of these design factors will affect the performance and cost of the gearbox. There are many 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 found in applications requiring sluggish speeds. Spiral bevel gears have got curved and oblique the teeth and are found in applications needing high-functionality, high speed applications.
Physical Properties
Bevel gears are usually made of cast iron, light weight aluminum alloy or other steel components but vary between producers.
Note: Gears made from steel materials could be noisy when getting into connection with other gears and also make them susceptible to wear.
Applications of Bevel Gears
Bevel gearboxes use bevel gears and are mainly used in right position 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 should 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 type of innovation provides for a smooth and calm operation. Gearboxes using helical gears can be applied in high horsepower and efficient applications.
Physical Properties
Helical gears are usually made of cast iron, aluminum allow or iron material but can vary greatly depending on the maker.
Note: Gears created from steel materials can be noisy when coming into connection with other gears and also make them prone to wear.
Applications of Helical Gears
Helical gears are trusted in applications which require efficiency and high horsepower.
• Oil Industry
• Blowers
• Food and Labeling
gearbox construction 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 teeth mounted on a parallel shaft. The noise level of spur gears is definitely relatively high because of colliding teeth of the gears which will make spur gear teeth prone to put on. Spur gears come in a range of sizes and equipment ratios to meet up applications requiring a specific speed or torque output.
Physical Properties
Spur gears are typically constructed from metals such as steel or brass, and plastics such as nylon or polycarbonate. The materials used to create spur gears may vary depending on the maker.
Note: Gears made from steel materials could be noisy when coming into contact with other gears and also make them prone to wear.
Applications of Spur Gears
Spurs gears are found in applications requiring a decrease in speed with high result torque.
• Cut-to-Length
• Packaging
• Speed Control
• Construction
• Power Plants
Advantages 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 are able to withstand high shock loads, lower in noise level and maintenance-free but are less efficient than additional equipment types. Worm gears can be used in right angle configuration. The worm gearbox configuration allows the worm to carefully turn the gear with ease; however, the apparatus cannot convert the worm. The prevention of the gear to go the worm can be used as a braking program. When the worm gearbox is not active, it is in a locked position.
