A set of gears provides a method to change the torque from a rotating object, such as the output shaft of a motor or engine, and either reduce the rate of rotation in exchange for an increase in torque (geared down), or increase the rate of rotation in exchange for a decrease in torque (geared up).
This is useful for a number of reasons. First of all many motors when hooked up to an electrical power source rotate at a very high speed and the desired rate of rotation is usually lower so the output from the motor is geared down. Secondly, motors are most efficient usually at a certain rate of rotation around 20% or so of the free speed (motor's output shaft rate of rotation with no load), and motors provide the most power at 50% of free speed. Using gears can help to achieve max power or max efficiency.

What is the purpose of a thrust washers in da back of the planetary and sun gears in the differential?
Thrust washers in the back of the planetary and sun gears in a differential help to maintain proper alignment and spacing of the gears. They also reduce friction and wear between the gears during operation, ensuring smooth rotation and efficient power transfer.
Does the planet venus have a purpose?
The planet Venus serves a scientific purpose of helping us understand planetary dynamics and solar system evolution. From a cosmic perspective, each planet plays a role in the balance and interactions within the solar system. Although Venus may not have a purpose in the human sense, studying it contributes to our broader understanding of planetary systems.

What type of gear is a bike?
Pretty much all bikes qualify as chain and sprocket gear systems, and the ones with internal gears also have planetary gears inside their hubs. There are also two systems available that puts planetary gears in the crank assembly. Well, if it has an internally geared hub it has a more or less complicated set of planetary gears(depending on the no of gears). If it has experna gears then it has front set of sprockets and a rear set of sprockets. By running the chain over these sprockets in different combinations you get different ratios that can be used depending on how hard the rider wants to pedal.
Brief explanation of epicyclic gear train?
Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer gears, or planetgears, revolving about a central, or sun gear. Typically, the planet gears are mounted on a movable arm or carrierwhich itself may rotate relative to the sun gear. Epicyclic gearing systems also incorporate the use of an outer ring gear or annulus, which meshes with the planet gears. Planetary gears (or epicyclic gears) are typically classified as simple and compound planetary gears. Simple planetary gears have one sun, one ring, one carrier, and one planet set. Compound planetary gears involve one or more of the following three types of structures: meshed-planet (there are at least two more planets in mesh with each other in each planet train), stepped-planet (there exists a shaft connection between two planets in each planet train), and multi-stage structures (the system contains two or more planet sets). Compared to simple planetary gears, compound planetary gears have the advantages of larger reduction ratio, higher torque-to-weight ratio, and more flexible configurations.
Where is the planetary gears in a Chrysler Town and Country van?

What is crown gear?

How does oversize tires affect your vehicle transmission?
Increasing tire size from the OEM tires will increase the stress load induced on the driveline. The planetary gears and carriers have to work harder than they were designed for and that creates a problem that leads to premature wear on planetary gears and on many other Automatic transmission components alike.
How do you release the drive system of a non working 853 Bobcat so it can be moved?
pull the final drives but mark the planetary gears because they are timed
Do bicycles have worm gears?
No. Bicycles with external gears have chain-and-sprocket gears. Bicycles with internally geared hubs have both a chain-and-sprocket gear and spur gears (usually in a planetary configuration) inside the rear hub. Then there are the rather rare shaft-drive bicycles, which use bevel gears. And maybe an internally geared hub as well. Then there's the occasional belt drive bike of course. And one or two CVT designs.
