Motor gearbox ratio calculator
P is the rated output power of the motor in kilowatts KW The denominator is the rated speed. Note that neither of these are equal to the gear ratio for the entire train 43.
Gearbox Output Torque Calculation Formula Sdt Transmission
We can calculate the torque power and RPM relation with this equation.
. Commonly used formulas for mechanical power transmission drives. The unit is revolutions per minute rmin. Our Gear Ratio Calculator allows you to determine what your Top Speed will be given the maximum safe RPM of your motor the number of teeth on the front and rear sprockets aka the sprocket and chainring and the diameter of your rear wheel enter in Inches.
Enter Shift at RPM select gear to shift to and hit Shift and Trace to run up through the gears recording shift point RPM and kmh - mph. Scroll through the list of popular transmissions to find yours. The calculation formula is T9549 P Iη n.
The reduction or gear ratio is calculated by dividing the number of teeth on the large gear by the number of teeth on the small gear. Thats the minimum of information that youll need to use this calculator. Calculate how much energy you are saving by switching to an efficient Sumitomo gear drive.
Enter gear ratios primary ratio sprocket sizes and tire diameter then drag RPM slider to calculate speed from RPM. Divide the number of teeth on each driven gear by the number of teeth on the drive gear for each interlocking set of gears to calculate the intermediate gear ratios. Calculator Gear Ratio Guide Speed and Gear Ratio Calculation Results Gear Ratio Calculator for Vehicle without Jackshaft This calculator determines the top speed of the vehicle with no margin for mechanical rolling or wind resistance.
Or change input variables engine RPM axle gear ratio and tire height to determine vehicle speed in each forward gear. The nearest ratio to this in Figure 2 is 7511 which is within 95 of the desired value and should work for an initial attempt. Ad Weve Been Putting Racers In The Winners Circle Since 1964.
The JVN Design calculator for FTC allows teams to calculate the gear ratio that is necessary for a mechanism like a drivetrain or arm. Not Finding What You Need. Come Join Us Today.
Torque Speed 955 Power In this equation the unit of the torque is Nm. In our example the intermediate gear ratios are 207 29 and 3020 15. We have a motor and gear ratio guide and online gear ratio calculator available at this link.
Solve For Gear Ratio ex. Give Us A Call To Place A Customer Oder. These resistance factors could make the top speed slower than the calculation.
If you know any 3 values Pulley sizes or RPM and need to calculate the 4th enter the 3 known values and hit Calculate to find the missing value. Weve Got Your Back. For example if Pulley 1 is 6 diameter and spins at 1000 RPM and you need to find Pulley 2 size to spin it at 500 RPM enter Pulley 1 6 Pulley 1 RPM 1000 Pulley 2 RPM.
Get the power transmission solutions you need with our full selection of technical calculators. Gear Ratio Calculator Ring-and-pinion selection made easy. Gear ratio is determined solely by the number of teeth on each gear.
Gear Ratio Calculator A simple gear ratio calculator to find the speed and mechanical advantage of a gear system of spur gears. With this example you will understand the gear ratio. Use this calculator to determine your gear ratio and vehicles speed in any gear and any engine RPM for best performance.
The unit of power in kW. If the electric motor speed is 1500 rpm the gearbox reduces. It was developed by John V-Neun coach of FRC 148 and was initially designed for.
To calculate the torque this motor-gearbox combination will produce multiply the motor continuous torque see Figure 1 by the gear ratio and gearbox efficiency see Figure 2 as follows. Drag Max RPM slider to adjust the range of the RPM and Speedometer Gauges. Just type in your info example.
Save yourself the headache and let us figure out your ring-and-pinion gear ratio. Reducer torque 9550motor powerspeed ratiouse efficiencymotor input revolutions. This is a very valuable resource for picking appropriate gear ratios for almost every application you need.
And the unit of speed is RPM. Check the box if the gear is on the same shaft as the gear above it leave it unchecked if the gear meshes with the gear above it. Recommended lubrication intervals for Cyclo reducers and gearmotors.
5000 RPM press calculate and youll get the right ratio without the guesswork. 5000 Tire Diameter in ex. For example if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear a reduction of 51 is achieved 65 13 5.
