What are the benefits of a gear drive?

Gears and Gear Drives They are used to transmit power to a driven piece of machinery and to change or modify the power that is transmitted. Modifications include reducing speed and increasing output torque, increasing speed, changing the direction of shaft rotation, or changing the angle of shaft operation.

What is best timing belt or chain?

If you don’t choose a car engine model with many failed timing chain reports, a timing chain is much better than a timing belt. While a timing chain might be far more expensive to replace, the odds are that you’ll never have to replace it.

What is the greatest advantage of using a timing belt instead of any other timing drive?

High mechanical efficiency, as much as 98\% when properly maintained. By contrast, chain drives are in the 91-98\% efficiency range, while V-Belts average in the 93-98\% range.

Is timing gear the same as a timing belt?

Despite having the same functionality, Timing Belts-Chains Or Gears are unique in their design. At first, engines used timing gears but, slowly evolved to timing chains. Later, timing belts came around and were quieter, but, problematic.

What are disadvantages of gear drive?

It requires proper lubricant and reliable process of applying it, for the proper operation of gear drives. As the manufacture of gears requires special tools and equipment, thus it is costlier than other drives. The inaccuracy in cutting teeth can cause vibrations and noise through operation.

Why are gears better than belts?

Instead, gears are machine elements used to transmit rotary motion between two shafts, normally with a constant ratio….Gear drive or belt drive?

Gear drive	Belt drive
Requires regular lubrication.	Requires relatively less or no lubrication.
Noisy in operation.	Very quiet in operation.

How long should timing chains last?

between 80,000 and 120,000 miles
When does a timing chain need to be replaced? The timing chain normally needs to be replaced between 80,000 and 120,000 miles unless there is a specific problem. Issues with the chain are common in higher mileage vehicles.

What is the disadvantage of using a timing belt?

Disadvantages of timing belt drive They are not economical. Need a sophisticated design of the belt as well as the pulley. Clutch action not possible. No protection against overloading.

Which is better timing chain or gear?

A gear driven system will always be much more stable, accurate, and last longer than any belt or timing chain, even a double-timing chain setup. The disadvantage to it is that they are typically noisy, require more lubrication than other methods and adds more overall costs to other motors designed without it.
