The gear ratio is the ratio of the number of teeth in the cogs, so 10 and 20 teeth produces the same effect as 20 and 40.
As for why you'd use different sizes, it can depend on the size of the case or housing of whatever transmission, differential, drivetrain, etc. that is involved. Obviously, you'd use larger gears so they can withstand heavier use.
What else can I help you with?
Are gear ratio s the exact same in rear and front?
If it is going to be driven on roads / black top then they both MUST be the same gear ratio. If you are building a MUD TRUCK and it will NEVER be on a hard surface then they can be different.
Is the front end gear ratio the same as the rear end 4x4 tracker?
Yes it has to be the same, Unless it's a MUD DRAG RACING truck. If they are not the same ratio. Then when the truck was on payment and the tires could not SLIP It would BREAK something in the drive-train because they would be pulling against each other at different speeds. BANG SOMETHING BREAKS. Two different Gear Ratio= Two different speeds.
Why do gears have a gear ratio?
When one gear is used to drive another, the number of teeth on each gear will factor into the ratio. Even if the number is the same it will have a 1 to 1 ratio. In a rear axle, for example, a common ratio is 41 teeth on the ring gear (driven gear) and 11 teeth on the pinion gear (drive gear). 41/11 is 3.727272 or commonly called a 3.73 to 1 ratio. It take 3.73 turns of the drive gear to get one turn of the driven gear. If you are interested, the different ratios provide different combinations of speed and power. Thus a large gear pulling a smaller one gives speed while a smaller gear pulling a larger one gives power.
Why are squares similar but not congruent?
They may be of different sizes. Congruent figures have the same size.They may be of different sizes. Congruent figures have the same size.They may be of different sizes. Congruent figures have the same size.They may be of different sizes. Congruent figures have the same size.
What determines rear axle ratio?
The # of teeth on the ring gear and the pinion gear. There is always more teeth on the ring gear then the pinion gear. And the way you determine the gear ratio is devide the # of teeth that's on the pinion gear into the # of teeth that's on the ring gear and that will be the gear ratio. The 4 gears that are the same size and run together is called the spider gears. Do not count those gears they have nothing to do with the gear RATIO.
Is the diff ratio the same on a standard and auto Chevy silvarado?
Probley not a stright stick trans. is geared different then a automatic. But the rear end gear ratio. could very well be the same. Not sure I understand your question.
What is a non-hunting gear ratio?
a ratio where each tooth to tooth contact is different each time. one tooth does not contact the same tooth more than once per revolution
Why would you ride a bike with some gears that have almost the same gear ratio?
huh?
Why are pond population the same at different sizes?
They are not usually the same.
Is a 1982 GMC half ton 2wd rear diff housing the same as a 1982 Chevy half ton 4wd rear diff housing?
The HOUSINGS are the same, But the gear ratio is probley different.
Why does your car skip gears?
To get higher speeds, thesecond gear has a lower gear ratio as the first one, so youre speed raises with the same rpm. The same for the 3rd/4th/5th/6th gear.
Can a square with different sizes have the same perimiter?
There's no such thing as "a square with different sizes". I'm thinking that youmust have meant "two squares with different sizes". The answer is still "no".
