Chain drives remain the most common, but belt drives
Belt drive
A belt is a loop of flexible material used to link two or more rotating shafts mechanically, most often parallel. Belts may be used as a source of motion, to transmit power efficiently, or to track relative movement. Belts are looped over pulleys and may have a twist between the pulleys, and the shafts …
What is the difference between chain drive and belt drive?
Chain drives have the strength to lift a two car and three car garages without any trouble. On the other hand, a belt drive will have trouble lifting garage doors made from heavy wood, two or three car garage doors and anything that’s heavier for the recommended weight.
How long does a bike belt drive last?
Belt drives last longer than chain drives- A properly maintained belt drive can last 3-5 times as long as a chain drive. Some riders have gotten 20,000 miles (around 30,000 km) out of a single belt.
Why choose a belt driven bike?
Belt driven bicycles are very popular among commuters for their low maintenance requirements and cleanliness. Bicycle tourists and bikepackers are switching to belt drives due to the long maintenance intervals.

What are the benefits of using a chain drive?
Chains are more efficient at low power inputs- For casual cycling, you’ll burn slightly less energy by using a chain drive. Bottom bracket and rear hub bearings last longer- Chains run at a lower tension than belts. This puts less stress on the bearings so they don’t wear as quickly.
Which garage opener is better belt or chain?
Chain Drive Openers The chains used on residential garage door openers typically have higher tensile strength and greater lifting capacity than belts. They also may last longer in certain applications.
Is a belt driven motorcycle better than chain?
Compared with a chain, belts are cleaner, lighter, cheaper, smoother, quieter and require less maintenance or adjustment than chains. Early belts were not very reliable and lasted as little as 20,000km. However, they now last 70,000-120,000km or higher, depending on the use of the motorcycle.
What are the advantages of belt drive over chain drive?
The advantages of a belt drive include:Belt drives are cost-effective. ... They are simple to use.Belt drives do not require parallel shaft.They have a low maintenance cost.They come with overload and jam protection.Different speeds can be obtained by means of step or tapered pulleys.More items...•
Which is stronger belt or chain?
Today's synchronous (toothed) belts are as strong as chains and not much wider, but they can't wrap as tightly so they need a larger countershaft pulley (and correspondingly large rear pulley to attain the proper gear ratio) than a chain setup.
Which drive is best for motorcycle?
Besides giving you the smoothest driving experience, a shaft-driven motorcycle also has a longer lifespan than that of a chain-driven motorcycle. They offer much less noise and go longer periods without maintenance as compared to chains.
How long does a motorcycle belt drive last?
100,000 milesBecause a drive belt can last up to 100,000 miles before needing replacement, riders may lose track of this important part of motorcycle maintenance.
What is the disadvantages of chain drive?
Disadvantages of chain drive The production of chain drive is higher than belt drives. The chain drive needs accurate and careful mounting. The chain drive need careful maintenance, lubrication and slack adjustments. If there is no frequent proper lubrication the chain wear out faster than belts and ropes.
What are the disadvantages of belt drive?
Disadvantage of belt driveLimited 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.
Why do Harleys use belt drives?
There are good reasons to adopt belt drive: It requires no lubrication, lacks the sound of a roller chain, and cannot stretch because it doesn't have a chain's 100 or more joints to wear.
Why are belts better than chains?
Belts offer a few nice advantages over chains: a longer wear life (30,000km!), little to no drivetrain maintenance (no lube or degreaser), silent operation and a lower weight too.
Why are chain drives better?
The chain drive is stronger and more durable because it is made of metal. It is also more dependable to use and easier to repair. Moreover, it is easier to change gears in the instance when the chain is broken.
Can you convert chain drive to belt?
With the help of a skilled professional, you can switch from a chain drive to a belt drive motor if you need to keep the noise down. Alternatively, you can install a chain drive if your garage door is wider and heavier than the standard sizes.
Why do Harleys use belt drives?
There are good reasons to adopt belt drive: It requires no lubrication, lacks the sound of a roller chain, and cannot stretch because it doesn't have a chain's 100 or more joints to wear.
Why do motorcycles still use chains?
Chain drive systems are lightweight and easy to service, though they do require cleaning and re-tensioning regularly. Because of their design, chain systems also smoothly absorb shock loads from sudden acceleration, sudden braking, or road irregularities. They also contribute to greater fuel economy.
Why does a bicycle has a chain drive rather than a belt drive?
Chains are more efficient at low power inputs- For casual cycling, you'll burn slightly less energy by using a chain drive. Bottom bracket and rear hub bearings last longer- Chains run at a lower tension than belts. This puts less stress on the bearings so they don't wear as quickly.
