Gear Ratio Motor

Gear Ratio Motor. In our example we would find the gear ratio by dividing the thirty teeth of the driven gear by the seven teeth of our new driver 30/7 = about 43 (or 43 1 etc) This means that the driver gear has to turn about 43 times to get the much larger driven gear to turn once 3 If desired find the gear ratios for the intermediate gears.

gear ratio = (input gear teeth number * (gear thickness + teeth spacing)) / (output gear teeth number * (gear thickness + teeth spacing)) But since the thickness and spacing of the gear train&#39s teeth must be the same for the gears to engage smoothly we can cancel out the gear thickness and teeth spacing multiplier in the above equation leaving us with the equation below.

How To Calculate Gear Ratio HBReducer

Now by using the gear ratio formula we looked at earlier we can determine the ratio across the gears The first gear set is 30 over 10 or 3 to 1 And that the ratio across the second gear set is 40 over 10 or 4 to 1 This information can be used to determine the ratio across the entire series of gears That’s done by multiplying the ratio of the first gear set by the ratio of the second gear set.

Motor and Gear Ratio Guide and Calculator

Gear Ratio Calculator for Vehicle with Jackshaft This calculator determines the top speed of the vehicle with no margin for mechanical rolling or wind resistance These resistance factors could make the top speed slower than the calculation The amount that the top speed will be reduced by resistance depends on many factors such as the power of the motor weight of the vehicle and rider size and air pressure of the tires incline degree that the vehicle is going up and headwind.
