How to calculate the gear ratio of Speed Reducer (gearbox)?

Formula: i = n1 ÷ n2

Note: i – Ratio, n1 – Input Speed(r/min), n2 – Output Speed(r/min)

How to calculate the output torque of speed reducer (gearbox)?

Formula: T = 9550 × P ÷ ( n1 ÷ i ) × η

Note: T – Torque, P – Motor Power, η – Mechanical Efficiency, η < 1
