Divide the number of teeth on each “driven” gear by the number of teeth on the “drive” gear for each interlocking set of gears
to calculate the intermediate gear ratios. In our example, the intermediate gear ratios are 20/7 = 2.9 and 30/20 = 1.5.
Do you add or multiply gear ratios?
You can calculate the rpm of the driven gear by dividing the driving gear RPM and the gear ratio. For example, 500 rpm/3 equals 166 rpm. You can also calculate the total gear ratio by
multiplying the gear ratios of all the individual gear stages
.
How do you find the gear ratio of 3 gears?
Divide the number of driven gear teeth by the number of drive gear teeth
. In our example, it’s 28/21 or 4 : 3.
What is a 5 to 1 gear ratio?
For example, if a motor drives a 12T gear to a driven 60T gear on an arm, the
12T driving gear has to rotate 5 times to rotate the 60T driven gear once
. This is known as a 5:1 ratio. The torque output is 5 times as much, however, the speed output is only 1/5. … The driving gear has more teeth than the driven gear.
How do you calculate multiple gear ratios?
The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear
(i= Ze/ Zs)
.
Which gear ratio is faster?
A lower (taller) gear ratio provides a higher top speed, and
a higher (shorter) gear ratio
provides faster acceleration. . Besides the gears in the transmission, there is also a gear in the rear differential.
How do you find the gear ratio?
Divide the number of driven gear teeth by the number of drive gear teeth
. In our example, it’s 28/21 or 4 : 3. This gear ratio shows that the smaller driver gear must turn 1,3 times to get the larger driven gear to make one complete turn.
What is a good gear ratio for highway driving?
For on-highway linehaul, the range tightens to a fuel friendly
2.26 through 3.42
for the most common ratios. “For on-highway, direct drive, it starts all the way down at 2.26 and up to 3.08 or larger,” Garrison says. “Getting into the mid- and upper-threes is starting to get more unusual these days.”
What is a good first gear ratio?
For most street performance applications, a
10:1 final First
gear ratio is usually considered optimal. The disadvantage of operating a 4.10:1 axle ratio on the street with a 1:1 high gear is excessive freeway engine speed.
What is the best gear ratio for 1/4 mile?
A
4.10 gear
would be your best bet to get because it will push the weight out of the hole and it would be easier to adjust your MPH with tire size.
What gear ratio is best for jerkbaits?
Jerkbaits: Jerkbait fishing is optimized by using a reel that has a gear ratio of
approximately 6.3:1 or slightly higher
. This speed reel allows for enough power to straight retrieve deeper diving jerkbaits, but enough speed to take in line slack when going through the jerkbait retrieve cadence.
What gear ratio is best for chatterbait?
A gear ratio of
at least 6.3:1
should be sufficient. Burning a chatterbait over the tops of grass is a very effective strategy. When burning line in quickly it really makes a bladed jig cause a lot of disturbance just below the surface and in the right conditions a big bass will smash the lures as a reaction strike.
How do I maximize my gear ratio?
If you want to create a high gear ratio,
nothing beats the worm gear
. In a worm gear, a threaded shaft engages the teeth on a gear. Each time the shaft spins one revolution, the gear moves one tooth forward. If the gear has 40 teeth, you have a 40:1 gear ratio in a very small package.
Does gear ratio affect horsepower?
Does gear ratio affect horsepower?
It doesn’t affect horsepower or tourqe at all
. Gears make your rear tires turn faster or slower. It also effects your top end speed and milage.
What gear ratio is best for fuel economy?
For instance, a
3:31
gets better fuel economy than a 3:73. On the other hand, a 3:73 or perhaps a 4:10 will tow much more, while fuel economy greatly drops. The most popular rear end ratio in trucks today is the 3:55, which sort of averages towing power and fuel economy.
What is a good gear ratio for hill climbing?
If you don’t want to stray out too far, a
46/17 to 42/17
are good gear ratios for smaller and occasional hills. These gear rates are considered a good middle ground that can be used in flat and hilly areas.
