The gear ratio calculator uses 2 combinations of gears to output an overall drive ratio. The first set is the main gear set which is generally starting at the motor or nitro engine. The next gear ratio is an internal transmission ratio or most commonly a differential gear ratio How to Find the Gear Ratio of Your Vehicle. Learning to calculate the gear ratio is easy. Looking for it in your car can be a challenge, especially if you do not have your owner's manual. Manufacturers always put the gear ratio information in their vehicle owner's manual for reference purposes Any two gears will have a ratio; if your car has a 20-tooth (20T) pinion and a 100-tooth (100T) spur gear, that's a 20:100 ratio. We need to go one step further, however, and divide the number of teeth on the spur gear (100) by the number of teeth on the pinion (20) STREET PERFORMANCE CALCULATOR. Rear End Ratio @ Desired MPH: Tire Diameter (Height) in Inches: Over Drive Ratio (1 for no OD) RPM at Given MPH : Known RPM @ Known MPH: Tire Diameter (Height) in Inches : Estimated Rear End Ratio. The gear ratio is the relationship between the number of teeth on two gears that are meshed or two sprockets connected with a common roller chain, or the circumferences of two pulleys connected with a drive belt. 1 General description 2 Wide-ratio vs. close-ratio transmission 3 Idler gear 4 External links In the picture to the right, the smaller gear (known as the pinion) has 13 teeth, while.

In a 4.10 gear set you will have to rotate the pinion gear 4.1 times to rotate the ring gear once. How to Choose the Best Gear Ratio. Now that we know a little more about gear ratios and how they affect your car, let's look at how to choose a gear ratio tailored to your car EndTuning - A simple calculator to work out what road speed you will achieve at a given RPM, or calculate your RPMs from a given road speed. This will be able to demonstrate increases with In-Gear speeds for increase RPM limiter How do we calculate the gear ratio ? If you need to amplify the motor torque with a factor of 3 then you need a gear reducer with a 3.0 gear ratio. In order to calculate the gear ratio of the two meshed gears we need to know either: the number of teeth of both input and output gears; the base diameter or radius of both input and output gears If the car is running a smaller-displacement engine like a 5.3L that we're spinning it to 7,000 rpm, then likely it will be more drastically affected by a reduction in gear ratio because small.

The gear ratio is the ratio of the number of turns the output shaft makes when the input shaft turns once. In other words, the Gear ratio is the ratio between the number of teeth on two gears that are meshed together, or two sprockets connected with a common roller chain, or the circumferences of two pulleys connected with a drive belt You may also use the RCI gear ratio calculator. Determine Torque Multiplication from a gear Ratio. Torque multiplication always occurs when there are two meshing gears of different number of teeth. The torque multiplication can be calculated directly based off of the gear ratio. As an example, we will use a gear ratio of 10:1

The gear calculator contains two functions. First, the gear calculator will help find the smallest fraction which represents a target ratio, and find the prime factors of the numerator and denominator. For example, suppose we want to create a gear system with a target ratio of 24 to 1, because we're building a 24 hour clock Fill in your values by double clicking on number. Then click on when finished. You can also now calculate when using different transmission gear ratios, like in first gear or in overdrive.If you do not know this ratio, you can simply put in 1.00 as this is the typical 4th gear ratio of most 4 sp and 5 sp manual transmissions 3-speed manual transmission in 3rd gear; 5-speed (or higher) manual transmission in the last gear; The ratios used for the transmissions are 0.70 for the automatic and 0.80 for the manual; You know the ring gear and pinion gear ratio. See the Gear Ratio calculator in the Spicer Tool Kit to determine your ratio. You know the tire height in inches Gear ratio fuel economy calculator. Using a gear ratio calculator helps in finding an effective gear ratio for your vehicle with new tire size. It aids in determining the best ring and pinion gear ratio for your car; thus, optimizing fuel economy, performance, and everyday driving. Auto repair and tire shops provide information charts on gear. In mechanical engineering, a gear ratio is a direct measure of the ratio of the rotational speeds of two or more interlocking gears. As a general rule, when dealing with two gears, if the drive gear (the one directly receiving rotational force from the engine, motor, etc.) is bigger than the driven gear, the latter will turn more quickly, and vice versa

Gear Ratio. Try our simple and easy to use Gear Ratio Calculator to quickly find the correct gear ratio for your differential. Simply enter the number of teeth on your ring gear and pinion gear and click the Solve button Low ratio gears are gears where the pinion gear (attached to the motor) has fewer teeth than the ring gear (the gear it turns). So if the pinion gear has 10 teeth and the ring gear has 30 teeth, the ratio is 1:3. The pinion gear has to spin three times to make the ring gear spin once. This is good for torque but not speed Ford is prominent manufacturer in car industry. Many vehicles have been produced. Besides producing car, Ford also creates its own gear.
