How to check the gear ratio by turning the tire?
Spin the tire one full turn or 360 degrees. Count how many times the drive shaft rotates. If the driveshaft rotates 3 1/2 times and the tire rotates once, you have an approximate rear axle ratio or final drive ratio of 3.5 to 1. If it rotates 4 1/4 times, you have an approximate ratio of 4.25 to one and soon.
Rotate the wheel TWO and count the number of revolutions of the propeller shaft. The number of revolutions of the propeller shaft will help determine the rear axle ratio. For example, if it spun 3 and a half times, that's a ratio of 3.50:1. If it's turned 4 and a quarter times, that's a ratio of 4.25:1.
With the transmission in neutral, turn the rear propeller shaft by hand.Count the number of revolutions of the drive shaft required for one revolution of the tyre. If the propeller shaft rotates about 3-1/2 times, you have a gear ratio of 3.54, etc.
Open Differential Gear Ratio Test:Lift one side and turn the tire 2 full turns, carefully counting the number of full turns of the drive shaft or pinion yoke. The number of revolutions of the drive shaft will indicate the gear ratio of the ring and pinion.
Simply defined, the gear ratio of a spinning reel isthe number of revolutions of the reel rotor and the guide roller during one full 360 degree rotation of the reel handle.
The translation to look for:
For a quality medium sized reel you will want to buy a reel with6:1ratio. This will allow you to retrieve just the right size lures very quickly, but it is not so strong that you will be flitting fish across the surface like small pieces.
The "downshift" or gear ratio is calculated bydividing the number of teeth of the large gear by the number of teeth of the small gear. For example, if an electric motor drives a 13-tooth pinion that meshes with a 65-tooth pinion, a reduction of 5:1 (65/13 = 5) is achieved.
The basic formula saysSpeed = Distance/Time. This formula shows that speed is directly proportional to distance and inversely proportional to time.
The gear ratio is calculated bydividing the output speed by the input speed (i= Ws/We) or dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/Zs).
Here is the formula for calculating the gear ratio:(rpm x tire diameter in inches) / (final drive ratio x gearbox ratio x 336)= Actual numerical gear ratio to the ground from each engine revolution.
How does ratio work on a spinning reel?
The gear ratio tells you how many times the rotor turns around the spool in 1 full turn of the handle. So the rotor of a 5.7:1 reel will make 5.7 revolutions around the spool for 1 complete revolution. The lower the coefficient, the less turns, the higher, the more.
The drive wheel has fewer teeth than the driven wheel. For example,if the motor drives the 12T gear to the 60T driven gear on the arm, the 12T drive gear must turn 5 times to turn the 60T driven gear once. This is called a 5:1 ratio.
If you have smaller tires (e.g. 33 inch), then the gear ratio will be approximately three times the tire diameter.is perfect. If you have larger tires (e.g. 38 inch), a gear ratio of about four times the diameter is ideal.
If the gears are of different sizes, they can be used to increase the power of the turning force.The smaller wheel rotates faster but with less force, while the larger rotates more slowly with more force.
If you're new to a single speed bike or a fixed gear bike, the gear ratio is approx2,7-2,8will be perfect.
In the small/large gear configuration, when the small gear has completed a full rotation, the large gear has not yet completed a full rotation. Sosmaller gearit makes more revolutions in a given time, turning at a faster rate than the larger gear.
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/My) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/Zs).
The gear ratio tells you how many times the rotor turns around the spool in 1 full turn of the handle. So the rotor of a 5.7:1 reel will make 5.7 revolutions around the spool for 1 complete revolution. The lower the coefficient, the less turns, the higher, the more.
- Find the number of teeth or the diameter of the first (drive) gear.
- Find the number of teeth or the diameter of the second (driven) gear.
- To find the gear ratio, divide the number of driving gears by the number of driven gears.
Tire manufacturers calculate the aspect ratio based ondividing the height of the tire from the rim by its width. If the tire has an aspect ratio of 70, it means that the height of the tire is 70% of its width.
What is the gear ratio for dummies?
How to calculate gear ratio? only youcount the number of teeth of both gears and divide. So if one gear has 60 teeth and the other has 20, the ratio when the two gears are connected to each other is 3:1.
Repositioningi=d2/d1. d1 and d2 refer to the reference diameters of the 2 mating gears (gear 1 is the driving gear and gear 2 is the driven gear).
Divide the number of teeth of the ring gear by the number of teeth of the pinion. This will give you the axle ratio.
For many cyclists, it can just mean thattype of gear currently available in the standard range of mid-range road bikes, which is a 1:1 ratio between the smallest front sprocket and the largest rear sprocket on a 700C wheel, which is approximately 27 inches.

Inches Per Revolution (IPT)
The diameter of the spool affects the amount of line it reels per full turn of the handle. This is sometimes referred to as inches per revolution (IPT). The larger the spool diameter, the higher the IPT. The smaller the spool diameter, the lower the IPT.
Here is the formula for calculating the gear ratio:(rpm x tire diameter in inches) / (final drive ratio x gearbox ratio x 336)= Actual numerical gear ratio to the ground from each engine revolution.
There are complicated formulas for determining pulley ratios, but in general, layman's terms, simplydivide the driven component (pump) by the number of revolutions per minute, the driving component (motor or motor) evaluated by the number of revolutions per minuteto get the required coefficient.
The two-digit number after the slash in the tire size is the aspect ratio. For example, in sizeP215/65 R15tire, 65 means that the height is equal to 65% of the tire width. The larger the aspect ratio, the larger the sidewall of the tire will be.
By shifting to taller tires, you're aiming for a numerically higher gear ratio.The higher the gear ratio, the smaller the sprocket. You don't want to go too low to increase the power to the wheels and/or take the load off the rest of the drivetrain.
