Belt drives are employed to transmit load from the driving shaft of the motor to the driven shaft when they are separately located. There are two types of belting available for industrial use. For transmission of smaller loads, flat belts and for small and medium loads, V-belt drives are normally employed.
What are the uses of belt and chain drives?
Generally, both belt and chain drives are used to transmit mechanical power from one point to another. APPLICATION OF BELT AND CHAIN DRIVES
- Belt is used in the pepper grinding machine, and sewing machines.
- Chain is used in the bicycles.
- Chain is used in motorcycles.
- Chain is used in the pulley system used for elevators.
Why would you use a belt drive over a chain drive?
Unlike chain drive, which requires very frequent cleaning, tightening and maintenance, belt drives are relative maintenance free. Belt drive systems also run much smoother, with much less jerks as compared to chain drives, and produce incomparably less noise too.
What machines use a belt drive?
Belt systems are used in grain belt conveyors, sawmills, printing presses, punch presses, and more. They’re even used in exhaust fan systems and laundry machinery. They’re most commonly used when the two shafts (driving and driven) are very far apart, as in a grain belt conveyor.
How do belt drives work?
In belt drives, power is transmitted between at least two pulleys by a belt. One pulley drives the belt (driving pulley) and the other pulley is driven by the belt (driven pulley). In belt drives, the speed is often reduced, so that in these cases the smaller of the two pulleys is the driving pulley.
Why do we use belts?
Benefits of a Weight Belt It reduces stress on the lower back while the person is lifting in an upright position, and it prevents back hyperextension during overhead lifts. A belt can also help can help beginning lifters learn to squeeze their ab muscles properly.
Is belt or chain drive better?
Belt-drive garage door openers are generally more expensive than chain-drive systems. But with a belt-drive system, you get a smoother, quieter, and more durable operation. Many homeowners find that the extra expense is worth it, provided that the belt-drive system is able to lift the door.
Are belt drives good?
A belt drive has substantially more durability than a chain. As a result it can last up to four times as long as a conventional bicycle chain. It will never need lubrication in the same way that a chain would and as a result is less likely to pick up associated dirt. Cleaning can be as simple as a quick wipe down.
What are the 2 types of drive belts?
- Flat belts have thin cross-sections and wrap around pulleys easily.
- V-belts come in.
- Synchronous belts have several tooth shapes.
- Link-type belts are used to make instant V-belt replacements.
- Improper drive maintenance is the biggest source of belt drive problems.
Where are belt drives used in the real world?
The treadmill is another great example of a belt driven mechanism. The belt in this drive system is not to be confused with the tread on which the runner directly runs; rather the belt drive system is the toothed, synchronous belt that transfers the rotary motion from the central motor to the drive pulley.
What are the advantages of gear drive?
Advantages of Gear drive
- It is positive drive hence velocity remains constant.
- Provisions for changing velocity ratios can be made with the help of gear box.
- Its efficiency is very high.
- It can be used even for low speeds.
- It can transmit high torque values.
- It is compact in construction.
