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.
30 mar 2021 · You can set the transmission ratio to 1:1 value, calculate the ratio based on transmission gear sizes or manually enter the ratio if it is already known. It is presumed that the transmission consists of 3 gears.
Calculate your ratio, your final drive ratio (FDR), and rollout, and see exactly how much of a difference a gear change will make.
The gear ratio is 5:1 (five to one), and that means that the pinion must make five revolutions to turn the spur gear one revolution. It’s that simple. You don’t need to spend a lot of money to add gearing options to your pit box. Robinson Racing offers convenient pinion “6 packs” for about $15.
Changing the gear ratio is an easy way to alter the performance of your RC car. You can gear for a higher top speed at the expense of slower acceleration, or vice versa. You can alter your car’s gear ratio by using a different pinion or spur gear.
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.
8 lut 2024 · The overall gear ratio of the gearbox is: GR2=T2/T1xT3/T2=T3/T1. Note that gear 2 does not affect the gear ratio. Its only function is to make the direction of rotation of gear 1 the same way of gear 3. The drive shaft transfers motion from the gearbox to the axle.
