*The advantage of a chain drive that uses sprocket gears over using spur gears is the ability to transfer torque and speed over longer distances .
What are the advantages of using chain drives?
- They can be used for both long and short distances.
- A number of shafts and be driven from a single chain.
- They are compact and have small overall dimensions.
- They do not present fire hazard.
- Temperature and environmental conditions do not affect their working.
- They do not require initial tension.
What are the advantages of chain drive over gear drive?
| Chain Drive Gear Drive | Chain drive is not suitable for very high speed reduction. Gear drive can be advantageously used for small to high speed reduction. |

What is the main advantage of a chain and sprocket mechanism over a belt drive?
An advantage of chain drives over most belt drives is that the chain cannot slip on the sprocket , so the chain and sprocket provides a positive, non-slip drive, i.e. the chain cannot slip on the sprocket because the sprocket teeth prevent the chain from slipping. Some belt and pulley drives also have teeth.
What are the advantages and disadvantages of chain drives?
- No slip and creep during the power transmission, it ensure the perfect velocity ratio. ...
- High transmission efficiency than friction drive.
- They can be operated under adverse thermal and atmospheric conditions.
- It can operate under wet conditions.
What are the disadvantages of gear drive?
- They are not suitable when shafts are distant.
- At high speeds noise and vibration happens.
- It requires lubrication.
- It has no flexibility.
What are the disadvantages of belt drive?
- Limited Speed range.
- They are not compact.
- Considerable power loss.
- Short service life compared to other mode power transmission.
- The velocity ratio may vary due to belt slip.
- They inflict a heavy load on shafts and bearings.
What are the application of chain drives?
Chain drives are used in many types of industrial applications, such as: Rigging and moving heavy materials . Hydraulic lift truck fork operation . Increasing or decreasing a driver’s output speed by altering gear ratios between the driver and the sprocket being driven.
Which is more efficient belt or chain?
A worn chain drive is about 4% less efficient than a worn belt drive . Testing shows that Gates Carbon Drive belts are the clear winner when you measure the efficiency of a worn belt to a worn chain. Gates belts keep their efficiency over time, while chains continually lose efficiency. This is because chains stretch.
Is belt drive better than chain?
It is evident that the two drives function the same way, but a chain drive is more durable than a belt drive . Unlike belt drives, chain drives can lift and move more massive doors, which is why many prefer it. Chain drives are best for steel carriages and not suitable for less heavy door models.
What is the advantage of belt drive over chain drive?
They run clean as they don’t have to be lubricated with sticky lubes and don’t require cleaning either. Belt drive systems also run much smoother, with much less jerks as compared to chain drives, and produce incomparably less noise too.
Why is chain drive better than belt drive?
Chain drives are made of metal, which makes them more durable and stronger compared to a belt . The metal chain is designed to have a design that corresponds to the other side. On the other hand, the belt drive is made of synthetic materials, and it is also flatter and smoother.
What are the advantages and disadvantages of gears over belt?
| Gear drive Belt drive | Requires less space compared to belt drive. Requires more space compared to gear drive. | Low friction loss compared to belt drive, therefore higher transmission and more efficiency. High friction loss compared to gear drive, therefore lower transmission and less efficiency. |

What are examples of chain drives?
A chain drive allows no slippage. An example is on a gearbox driving a conveyor . Chain drives are also used when a large amount of power is required through the drive. For example the drive on large rotating kilns.
What are the 4 types of gears?
- Spur Gear. Spur gears transmit power through shafts that are parallel. ...
- Helical Gear. Helical gears have teeth that are oriented at an angle to the shaft, unlike spur gears which are parallel. ...
- Double Helical Gear. ...
- Herringbone Gear. ...
- Bevel Gear. ...
- Worm Gear. ...
- Hypoid Gear.
What is law of gearing?
Law of gearing states that the common normal at the point of contact between a pair of teeth must always pass through the pitch point for all positions of mating gear . ... This is a must condition for the two gears to perform properly.
