The drive sprocket to driven sprocket ratio is a measure of the relationship between the number of teeth on the drive sprocket and the number of teeth on the driven sprocket in a chain or gear system. This ratio determines how speed and torque are transferred in the system; a higher ratio means the drive sprocket will rotate more times than the driven sprocket, increasing speed but reducing torque. Conversely, a lower ratio increases torque while reducing speed. This ratio is crucial for optimizing performance in applications like bicycles, motorcycles, and machinery.

How do you calculate sprocket rpm?

calculating sprocket RPM is very easy if you know what the RPM of the drive sprocket is. If you know that then it is a simple fraction problem. If you make the drive gear the numerator or the top part of the fraction and the driven gear the denominator or the bottom part of the fraction (DRIVE/DRIVEN) I.E. if the drive sprocket has 25 teeth and your driven sprocket has 100 teeth (25/100) that will reduce to (1/4) or a 4:1 ratio. So if your drive sprocket is spinning at 1000 RPM then your driven sprocket will be spinning at 250 RPM. You can plug your specific sprocket tooth count into that equation and come up with the right answer.


What is the relationship between driven gear and drive gear?

The ratio is the driven gear divided by the driver gear. This determines the gear ratio.


How do you calculate a gear ratio of a 5 tooth drive gear and a 15 tooth driven gear?

You take driven divided by drive. 15 divided by 5 is 3. So the ratio would be 3:1


What are teeth on bmx?

In the drive train you have the front chainwheel/ring and the rear sprocket that both engage the chain. The pointy bits on sprocket and chainwheel which allows the chain to grip are called teeth. The ratio between the tooth counts is what determines which gear ratio the bike has.


What is a good sprocket gearing for cfr 230f?

For the CFR 230F, a good sprocket gearing typically ranges between 12 to 16 teeth on the drive sprocket, paired with a larger driven sprocket of around 40 to 50 teeth. This gearing provides a balanced ratio for optimal torque and speed, enhancing performance for various applications. However, the ideal gearing can vary based on specific use cases, terrain, and load conditions, so adjustments may be necessary for optimal performance.


How do you calculate a gear ratio of a 9 tooth Drive gear?

Number of teeth on driven gear divided by teeth on driven gear.


How do you work out sprocket sizes for bmx?

Divide your rear sprocket into your front sprocket. Like 25x9. 25 divided by 9 = 2.77. so 2.77 to 1 is the drive ratio. If you go with a smaller sprocket like a 24 in the front but still a 9 in the back, you are lowering the gear ratio to 2.66 to 1. So your bike will be slower but easier to pedal. If you go with a 25 in the front and a 10 in the back, you end up with a 2.5 to 1 ratio. Don't confuse gear ratio with gear inches, that's a calculation including the wheel and sometimes the circumference of the tire.


What is the size of the stock sprokets on a 1991 Honda nighthawk?

I have a "Clymer Honda CB 750 Nighthawk 1991-1993 & 1995-1999" book. It says for sprocket sizes, "Drive Sprocket 15 teeth, Driven Sprocket 38 teeth". Nothing else listed in there or in the Owner's Manual as to size.


How fast will a 2003 Kawasaki KX 60 go?

About 40 miles per hour depending on the final drive (sprocket) ratio.


What is the Velocity Ratio In Belt Drive?

The Velocity Ratio (VR) in a belt drive system is the ratio of the speeds of the driving pulley to the driven pulley. It is calculated by dividing the diameter of the driving pulley by the diameter of the driven pulley. A higher velocity ratio indicates that the driven pulley will rotate more slowly than the driving pulley, which is important for applications requiring torque multiplication. This ratio is crucial in determining the efficiency and effectiveness of power transmission in mechanical systems.


What is the ratio between an 11 tooth sprocket and a 53 tooth sprocket?

Just a little short of 1:5


What size sprocket needed to get 46 rpm down to 2 rpm using a 10 tooth for the drive?

you need a ratio of 23 to one hence 230 teeth
