30 mar 2021 · RPM to transmission value: The amount of revolutions that the motor and pinion and spur gear combination will cause the transmission to turn in one minute. This is the RPM value entering the transmission through spur gear, not taking transmission ratio into account.
Try our gear ratio and rollout calculator to find the right pinion and spur for your car, whether it's Team Associated, Tamiya, Traxxas, or any other make. Enter your car's internal drive ratio to see the final drive ratio (FDR), and see the percentage change in gearing you'll get from a new pinion and spur.
Use the following calculator to determine the gear ratio of your radio control vehicle. 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 pinion and spur gears are the gear combination that transfers the power from the motor to the wheels of your RC car. Correctly setting up these gears will take your RC car’s performance to another level.
Use our RC gear ratio and rollout calculator to find the right pinion and spur for your car. Enter your car's internal drive ratio to see the final drive ratio (FDR), and see the percentage change in gearing you'll get from a new pinion and spur.
Spur Gear design formula for geometry, pitch, tooth clearance and critical functional data. (Inch Units Applicable for Constants) Spur Gear Design Calculator. Where: φ = Pressure Angle. a = Addendum. a G = Addendum of Gear. a P = Addendum of Pinion. b = Dedendum.
You can alter your car’s gear ratio by using a different pinion or spur gear. The pinion gear is the very small gear that fits onto the motor, and is usually made from some kind of metal. Common metals include Aluminium, Steel and Titanium.
