- 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.
How long do belt drive bikes last?
Belt drives can last
10,000-20,000 miles
before they need to be replaced. One way to extend the life of your chain drivetrain is to swap chains every 500 miles or so. Some riders have 4 chains that they rotate between.
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.
Are belt drives more efficient?
Belts are more efficient than chains at higher power outputs
– If you are a particularly powerful rider, you might see an increase in efficiency at power outputs over 212 watts. For more info, check out this excellent article about the efficiency of belt drives from Cycling About.
Are belt drive bikes faster?
According to Jason Smith at Friction Facts, the answer is
no
. By his measurements, a conventional chain drive consumes 2.92 watts on average, while the belt eats up 3.93 watts. Although the difference is just 1 watt – not enough for most people to care – this works out as a substantial 34.6 percent.
Is chain drive better than belt drive?
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.
Are belts better than chains?
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.
Why do V belts have teeth?
Friction drive belts rely on
the friction between the belt
and pulley to transmit power. They require tension to maintain the right amount of friction. … Positive drive or synchronous belts rely on the engagement of teeth on the belt with grooves on the pulley.
Are notched V belts better?
A notched belt has grooves or notches that run perpendicular to the belt’s length, which reduces the bending resistance of the belt. Notched belts can use the same pulleys as cross-section standard V-belts. They run cooler, last longer, and are
about 2% more efficient than standard V-belts.
How can I increase my belt drive efficiency?
Synchronous belts
require less maintenance and re-tensioning, operate in wet and oily environments and run slip-free. While synchronous belts are the most efficient, they can be noisy, transfer vibrations, and are unsuitable for shock loads. In such applications, cogged belts are the better choice.
Do belt drive bikes make noise?
The belt can make noise when forced to run hard against the flanges on the sprockets
. … Spraying water on the belt may quiet the drive for a few minutes, but the permanent solution is to correct the alignment or replace the damaged components. Another possible source of noise is a loose front sprocket.
How long does a carbon belt drive last?
You can expect a regularly cleaned belt drivetrain to last
upwards of 30,000km/19,000mi
. Additionally, belts will not rust if they get wet regularly (or are subject to salt near the beach).
Can I replace a chain drive garage door opener with a belt drive?
If you are looking for less frequent maintenance with your garage door, and less noise overall, you might want to consider converting the chain drive on your garage door to a belt drive. A garage door opener with a belt drive will give your home a quieter alternative for your garage door.
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. So why back to chain on this new “adventure-touring” model?
Are belt drive garage door openers quieter?
Belt Drive: Belt driven garage door openers use a belt instead of a chain to move your door. In terms of noise, belt driven openers
are much quieter compared to
chain driven openers. This makes them ideal for attached garages, however they are a bit more expensive.
What are the advantages of V belts over flat belts?
Advantages -1. The
V-belt drive gives compactness due to the small distance between the centres of pulleys
. 2. The drive is positive, because the slip between the belt and the pulley groove is negligible.
