	Gear Ratios,Transmission Gear Ratio,Drive Gear Ratio,Gear Ratio Chart,Gears and Gear Ratios,Transmission Gear Ratio ...
		Gear ratio is a number, usually expressed as a decimal fraction, representing how many turns of the input shaft cause one revolution of the output shaft.
		The special case of gear ratios are the engine speed of the car to the rotation of the drive wheels.
		The overall gear ratio is equal to ratio of ring and pinion gear multiplied by the ratio of speed gear the car is operating in.

		Multiple gears allow the bicyclist to select the appropriate gear ratio to match his or her power output to the slope and wind conditions.
		For each entry in the table calculate the ratio of the number of teeth on the front gear to the number on the rear, this is the gear ratio.
		Notice that the ratio of the force on the pedals to the force on the tire is the inverse of the ratio of the distances moved by the pedals to the distance moved by the tire.

	Gear ratio - Wikipedia, the free encyclopedia
		Diameter measurements are useful for determining approximate gear ratios for non-gear linkages such as pulleys and belts.
		In 4th gear, the gear ratio of 1:1 means that the engine and the transmission’s output are moving at the same speed.
		5th and 6th gears are known as overdrive gears, in which the output of the transmission is revolving faster than the engine.

		The idea behind multiple gears on a bicycle -- whether it's an older "10-speed" bike or a modern mountain bike with 24 gears -- is to let you change the distance that the bike moves forward with each pedal stroke.
		The "lowest" gear ratio on the bike might be a front chain wheel with 22 teeth and a rear gear having 30 teeth.
		The "highest" gear ratio on the bike might be a front chain wheel with 44 teeth and a rear gear having 11 teeth.

		The rearend gear ratio refers to the relationship between the ring gear and the pinion gear.
		Because transmissions are comprised of several gear choices, the transmission allows the vehicle to accelerate quickly with lower gears and to maintain a cruising rpm using higher gears.
		The disadvantage of operating a 4.10:1 axle ratio on the street with a 1:1 high gear is excessive freeway engine speed.

		The difference is the dimension from the ring gear mounting flange to the pinion centerline, due to the larger diameter pinion required for the lower numerical gear ratios.
		A set of 4-series gears can be installed in the 3-series carrier with a spacer and longer bolts (not desireable due to reduced strength), but the reverse is not true.

		"The gears are AGMA 12 and were cut and ground from a single bar of Aermet 100 with the shafts integral to the gears." This allowed them to both increase the strength of the parts and avoid the problems associated with shafts flexing and moving in their bearings.
		Gear manufacturers are encouraged to contact their local secondary and trade schools and provide copies of the video and brochures to the guidance staff.
		Nanogears, molecule-sized gears that are made from pipes of carbon atoms with benzene atoms attached to the outside of the pipe to form the teeth, have been simulated by a NASA supercom-puter at the Ames Research Center in Mountain View, CA, as part of their ongoing research into nanotechnology.

	Tire Size Vs. Gear Ratio - A Formula
		Your truck comes from the factory with the optimum axle gear ratio to work with the truck's engine, transmission, and stock tire combination as well as provide a good balance between acceleration and fuel economy.
		When taller tires are installed on a truck but the axle ratios stay the same; the effective gear ratio is reduced.
		Fortunately, finding the correct gear ratio to run with the tires that you plan to install is simple using a mathematical formula.

		It has a low gear that is over 5:1 as opposed to the stock 5 speed of 3.83:1 and an overdrive in the low.7's:1 as opposed to.79:1 in the stock 5 speed, and it is structurally a much stronger tranny too.
		Where a vehicle was stock with 3.73 gears and 30” tall tires and wanted to go to 35” tires it would need at least a 4.35 gear ratio to keep the same gearing it had stock.
		Since that ratio is probably not available one would need to decide between 4.10 or 4.56 gearing (some applications may have a 4.26:1 available).

	Optimum Rear Gear
		Figure I below is a chart of rear wheel torque increases; to find the torque increase for a proposed gear ratio change, find your present ratio in the left column and move across to the column that is headed by the proposed ratio, the percentage shown is the torque increase (negative percentages are torque decreases).
		The point of these examples is that a gear ratio that is perfect for one car could be a disaster in another car aiming for a similar performance goal, so you must consider the engine combination carefully when choosing the rear gear ratio.
		The two rear wheel horsepower curves show that increasing the gear ratio causes the horsepower peak to occur at a lower road speed but the peak horsepower value is the same.

	Simple theory of worm face gears.
		Gear cutting ratio has to be the same as the gear set ratio so it is impossible to have a hunting ratio for cutting if the gear set does not have it.
		The gear cutter has to have the same geometry that the pinion so it has to have the same number of the threads.
		Using oversized gear and pinion as electrodes does not solve the problem because it is impossible to cut the gear that is oversized in the same directions that plastic shrinks.

	GEAR FUNCTIONS
		The (right) driving gear with 20 teeth, 1 inch radius and 2 ounce-inches torque rotates CCW at 200 RPM and and exerts a 2 ounce force on the driven gear with forty teeth for a ratio of 2:1.
