What Is Industrial Gearbox ?
An industrial gearbox is an enclosed system that transmits mechanical energy to a transmission unit. The system slows down the speed and torque of rotation. Industrial gearboxes are different from standard gearboxes, as the former needs a long, stable life and safety factor for most of the drives. To control speed and torque and convert it functionally, an industrial gearbox transmits mechanical power into a driving tool. In contrast to mass gearboxes, industrial gearboxes can handle multiple tasks at extremely high speeds over a long period.
Importance of an Industrial Gearbox
An industrial gearbox helps facilitate mechanical operation in different industries. The main gearboxes used by industries include Helical gearboxes, coaxial helical lines, bevel helical gearboxes, skew bevel, and worm reduction gearboxes. The main industries in which there is a large use of an industrial gearbox are:
- Paper Industry
- Cement industry
- Sugar industry
- Steel industry
Important Tips for Industrial Gearboxe Maintenance
Regular maintenance is necessary for an industrial gearbox to operate at long-term intervals. A few easy-to-do maintenance tips are given below, which help to maintain an industrial gearbox well.
- You need to Store the industrial gearbox in a dry place. It is a very necessary precondition. To minimize the risk of unworked parts, the gearbox should be placed in a safe area. Regularly clean the storage area and machine. You can easily reduce the environmental impact by keeping the equipment and work environment free of dust, dirt, and waste. Before preparing a switch, always clean the inspection ports of the gearbox. Check also the collectors of magnetic debris and filters.
- Test if the industrial gearbox is used as per the thermal and mechanical ratings recommended by the manufacturer. The gearboxes are often worked beyond the prescribed specifications of the manufacturer and work at a higher power than required. This affects equipment efficiency and reduces the shelf life of the equipment.
- To prevent overheating, the temperature of the industrial gearbox must be checked periodically. Search for variations in temperature, too. Like foamed glass, discolored housings burned marks on the housings, and disfigured plastic components can be the symptoms of overheating. To check for overheating, you can perform a faster test: spray the water on the gearbox and see if that it evaporates, boils or cracks. The gearbox becomes overheated if the water disappears.
- Dirt, dust, and moisture are still seen through the breather through the industrial gearbox. Ensure that the right breather is used to avoid this.
- Use Lubricate Regularly. This is one of the preventive maintenance’s key steps in an industrial gearbox. Always use the recommended grade and type of lubricant in a suitable amount suggested by the manufacturer. Measure the lubricant’s strength and check for sight glass or oil leakage in the shaft seals for signs of low lubrication. Oil leaks indicate that the seals may not function well and require substitution.
- For noisy environments, an industrial gearbox mostly works so its noise changes can remain unnoticed. Any irregular noise may indicate components being affected. Regular vibrations examination of the gears and internal bearings can be carried out to test for device misalignment, part cracks, etc.
But wait! What is actually a Gearbox?
Generally, a gearbox is an integral part of so many machinery parts. To ensure maximum efficiency of any gearbox, routine maintenance should be carried out. The best way to manage a gearbox is to periodically test it to assess and fix potential faults before occurring
Physical Properties of a Gearbox
The physical components of a gearbox vary between its types and the variations between manufacturers. Most gearboxes are made of iron, aluminum, or brass materials. spur gearboxes can also be produced using plastics as polycarbonates or nylons, as are other gearbox types. In addition to the raw materials used, gear teeth orientation plays an important role in the overall device performance, torque, and speed. Simple gear teeth gearboxes usually are used for low-speed use. These gearboxes can be noisy and overall, less efficient. Usually, helical gearboxes are used for high-speed applications. These gearboxes are slower in operation and can improve overall efficiency than straightening gearboxes.
Types of Gearboxes (Industrial Gearbox)
Worm Gearbox
An industrial gearbox, especially in the form of Worm Gearboxes, is most commonly used for heavy-duty functions. This type of gear integrates a broad worm (or screw) diameter which meshes the teeth in the periphery of the gear. The device then makes it possible for the consumer to determine the rotation speed and for the transmission of higher torque. Worm gears are used for 90 degrees of transmission plus elevators and conveyor belts.
Helical Gearbox
Helical gearboxes are large and utilize low power. When two teeth start to meet, the teeth of helical gears are shut down to an angle to the face of the machine, by one end of the tooth and remain in touch as the machine rotates completely into contact. The design allows a smoother running of the industrial gearbox and allows for high load angles. The helical gearbox can also express movements between parallel and right shafts.
Bevel Gears
Bevel Gears have curved teeth on cone-shaped surfaces near the unit bottom. They can be used to rotate non-parallel shafts and have a broad range of applications, including rolling stock and mining.
Planetary Gearbox
In advanced technologies, such as robotics and 3D printing, this form of the gearbox (industrial gearbox) is common. Three of four planet gears surround a planetary gearbox with a central Sun Gear. Both these are held together via inner teeth outer ring equipment. This design similarly spreads power through the gears and makes it possible for a Planetary Gear System to achieve a high torque in a limited area. High endurance and precise are the two popular features of Planetary Gearboxes.
Gearbox Types Working: How do they Work?
All gearboxes work in the same way. The rotating directions of the gears depending on the direction of input and the orientation of the gears. For instance, the gear it engages rotates counter-clockwise if the initial gear is turned in a clockwise direction. This goes down for several gears. There is the same planetary gearbox operation. A planetary gearbox is composed of 3 main elements: the sun ‘s central gear, a planet carrier and an annulus (an outer ring). The central sun gears are mounted around the planetary gears (of the same dimensions). The planetary gears are meshed by the sun’s gear and the outer rings mesh with the planet’s gear. A gearbox system consists of many configurations including input, output, and one stationary component
The Use of Gearboxes
The technological advances and the development of gearboxes have resulted in the production of more efficient and powerful gearboxes (especially industrial gearbox) at a lower cost. Gearboxes are commonly used to monitor the direction of rotation and convert torque or power between inputs in applications that need desired output speed. A gearbox or an industrial gearbox is used in many applications, including machine tools, construction machinery, transporters, and any device that needs modifications in the torque and speed of rotating movement power transmission.
Which Bearing is Used in gearboxes?
There must be certain performance characteristics for bearings used in gearboxes including:
- low noise
- low vibration
- low heat generation
- lightweight
- high rigidity
- long operating life
