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.
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.
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.
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.
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.
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.
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.
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
huh?
The HOUSINGS are the same, But the gear ratio is probley different.
They are not usually the same.
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.
No, a ratio is not the same as its value. A ratio compares two quantities, expressing their relative sizes, while its value represents the actual numerical relationship between those quantities. For example, a ratio of 2:1 indicates that for every 2 units of one quantity, there is 1 unit of another, but the value of that ratio is 2. Thus, while related, they convey different concepts.
