Gear ratios are fundamental in understanding how gears work, with the ratio indicating how many times a gear has to turn for another gear to turn once; for instance, in a worm gear, a threaded shaft engaging the teeth on a gear can create a high gear ratio in a compact space. Planetary...
How gear ratios work Neutral All the gears except those needed for reverse are constantly in mesh. The gears on the output shaft revolve freely around it, while those on the layshaft are fixed. No drive is being transmitted. First gear ...
Planetary Gearsets & Gear Ratios Details on Involute Gear Profiles Gear Basics You've probably heard of gear ratios, especially when it comes to cars. The gear ratio is the number of turns the output shaft makes while the input shaft turns one time. If the gear ratio is 2:1, then...

Gear Basics You've probably heard of gear ratios, especially when it comes to cars. The gear ratio is the number of turns the output shaft makes while the input shaft turns one time. If the gear ratio is 2:1, then the smaller gear is turning two times while the larger gear turns ...
In terms of efficiency, diesel engines are more powerful and energy-efficient than gasoline engines. This is because diesel engines work on higher compression ratios. This gives about 20 percent more efficiency than gasoline engines at the same compression ratio. Why do trains have steel wheel? Tr...
A continuously variable transmission (CVT) has a nearly infinite range of gear ratios. In the past, CVTs could not compete with four-speed and five-speed transmissions in terms of cost, size and reliability, so you didn't see them in production automobiles. These days, improvements in design...

Following is a chart of gear ratio found in a MUV’s gearbox. However, the gear ratios vary from vehicle to vehicle. For example, the gear ratios are typically higher than cars in trucks as they carry a heavy load. How does a Gearbox work?
Controls the power contained in the crankshaft before it goes to the wheels and allows a driver to control the speed/power of a car by providing different speed/power ratios known as gears. So first gear gives plenty of power but little speed whereas fifth gear provides little power but ...
