Paano Kalkulahin si Gear Ratio
Ano ang Gear Ratio?
Gear ratio is the speed reduction/increase between input and output shafts. It determines torque multiplication and shaft speeds.
Pormula
Ratio = N_input / N_output = N_driven / N_driver = T_output / T_input
Step-by-Step na Gabay
- 1Ratio = N_input / N_output = N_driven / N_driver = T_output / T_input
- 2Spur gears: ratio = number of teeth on driven / number on driver
- 3Power is conserved: P = T × ω
Mga Nalutas na Halimbawa
Input
Input 1800 rpm, output 600 rpm
Resulta
Gear ratio = 3:1 (3× speed reduction, 3× torque increase)
Power unchanged
Mga Karaniwang Mali na Dapat Iwasan
- ✕Confusing speed ratio with force multiplication
- ✕Neglecting friction losses in extended calculations
Mga madalas itanong
Can any two gears mesh together?
No, they must have same pressure angle and pitch. Teeth must fit smoothly without interference.
How is efficiency handled?
Mechanical power loss (5-10%) converts to heat; P_out = P_in × η.
