It is 9.
Yes, it is exactly that.
Number of Driven Gear Teeth (Output)/Number of Driver Gear Teeth (Input)
The gear ratio of a train, also known as its speed ratio, is the ratio of the angular velocity of the input gear to the velocity of the output gear. The gear ratio is very important when it comes to physics.
What is the speed ratio of an input with 36 teeth meshed to a gear with 20 teet?
Input gears are usually small and attached to a rotating shaft. The input gear is connected to an output gears via a belt, band, cable, drive chain, or directly with the output gear. The output gear transmits and magnifies the rotational power received for the input gear.
That is a 4:10 gear ratio. Just divide the number of teeth on ring gear into the number of teeth on the pinion gear and then round it off and that will be the gear ratio.
Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
The input and output shafts need to be marked Then put in a particular gear Rotate the input shaft ten revolutions and count the output shaft revolutions. Or read the specs in the manual OR disassemble the trans and count the gear teeth.
Number of teeth on driven gear divided by teeth on driven gear. Example: 40 teeth on a ring gear and 10 teeth on a pinion will be a 4.00:1 ratio.
Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
3,because the gear ratio in a manual transmission results is a gear ratio of about 3:1 for first gear.
Number of teeth on driven gear divided by teeth on driven gear. Example: 40 teeth on a ring gear and 10 teeth on a pinion will be a 4.00:1 ratio.
