Understand that an ideal gear mesh conserves power: a gear ratio that reduces speed multiplies torque by the same factor, and vice versa.
Output Speed
1000 rpmOutput Torque
10.0 N·mGear ratio: GR = N2 / N1Output speed: ω2 = ω1 · (N1 / N2)Output torque: T2 = T1 · (N2 / N1)Make the driven gear (N2) larger than the driver gear (N1) — for example N1 = 20, N2 = 40. Confirm the output spins slower than the input.
