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
They weren't 'invented' - a gear ratio is simply the difference in the number of teeth on two connected gear wheels.
The gear ratio for top gear is chosen to produce maximum speed, which occurs at a speed where the engine's maximum power is take up with maintaining a constant speed (on the level). For cars the overall ratio for top gear is 3.5 to 4.5 : 1. For example, if the engine's maximum power is 100 bhp at 6300 rpm, and that power can drive the car at the maximum speed of 110 mph, the overall ratio is chosen to give 6300 rpm at 110 mph.
When you are driving there are gears that you can switch to.Hope this helps. :)Prior to replacement I consider the possibility of changing the gear ratios: could you use a higher gear?If the 4th gear ratio is too low ( high number ) then it will limit the speed the scooter can achieve.If you need a lower gear ratio the hub allows you to fit a larger rear sprocket, and vise versa.These also work. :)
according to velocity ratio i.e N1/N2 = D2/D1 which implies that diameter of gear is inversly proportaional to speed . hence, DRIVEN GEAR will move faster as it is smaller in size than the DRIVING GEAR
"Module" is the unit of size that indicates how big or small a gear is. It is the ratio of the reference diameter of the gear divided by the number of teeth. Thus:    (Module = Reference diameter ───────── Number of teeth )
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.
Incorrect gear ratio in first gear.Incorrect gear ratio in first gear.
The ratio is the driven gear divided by the driver gear. This determines the gear ratio.
Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
Probably a 3.08 gear ratio.
no, the carburetor has nothing to do with your gear ratio.
2.833 is the rear-end gear ratio
what is variable gear ratio steering steering system?
most Z's had the 3.42 gear ratio.
Gear ratio of bevel gears isnumber of ring gear teeth divided by number of pinion gear teeth.
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.
The gear ratio was whatever the customer ordered back then, you could get anything from a 2.76 ratio to a 4.10 rear gear.
