How do you calculate rear end gear ratio?
Count the number of teeth on the pinion gear and count the number of teeth on the ring gear. Divide the ring gear teeth number by the number of teeth on the pinion. The result is your gear ratio.
How do you calculate transmission ratio?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs).
How do you calculate motor RPM with gear ratio?
Write down the ratio of the speed reducer; for example, 12:5. Calculate the reduction by dividing 12 by 5, which equals 2.4. The RPM of the assembly is the RPM motor divided by the reduction. In our example, it would be 5000 RPM/2.4 = 2083 RPM.
How do you calculate final drive ratio?
By simply dividing the ring gear tooth count by the pinion gear tooth count, the ratio is determined. For example, if we divide a ring gear with 41 teeth by a pinion gear with 10 teeth we find that the gear ratio is 4.10:1 (41/10 = 4.10). Tire diameter will also have an effect on a vehicle’s final drive ratio.
What is velocity ratio formula?
The velocity ratio (V.R.) of a machine is the ratio of distance moved by the effort to distance moved by the load. Formula – Velocity Ratio = Distance moved by the effort / Distance moved by the load = y/x. The velocity of given machine can also be determined by assuming the machine to be ideal.
How to calculate the rear end gear ratio?
FIGURING REAREND GEAR RATIO (Ring & Pinion) FORMULA: Engine RPM @ Cruise / Tire Revolutions Per Mile = Rear-end Gear Ratio. EXAMPLE Without Overdrive: 1800 RPM / 656.93811 = 2.73:1. EXAMPLE Without Overdrive: 2000 RPM / 656.93811 = 3.04:1.
Is there a calculator that calculates the transmission ratio?
This calculator will provide the speed of the vehicle based on transmission gear ratio, engine RPM, tire height, and the ring gear and pinion gear ratio in the rear end axle differential housing. This calculator assumes you know the vehicle’s transmission ratio.
How to calculate rpm and rear axle ratio?
rpm = (mph x Rear End Ratio x 336) / Tire Diameter I knew my rear axle ratio was 4.10:1 and measured my tire height (on blacktop) and came up with an average of about 31 inches. I headed out to the highway and got my truck up to 65 mph in overdrive and set the cruise.
How is the RPM of a car determined?
Determine your engine’s RPM based on the transmission gear ratio, tire height, MPH and the ratio of your ring gear and pinion gear. This calculator will provide the speed of the vehicle based on the transmission gear ratio, the engine RPM, the tire height, and the ring gear and pinion gear ratio in the rear end axle differential housing.
