Gear Train

This interactive simulator explores Gear Train in Engineering. Connect gears, adjust teeth count, see speed and torque ratios. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Engineering.

How it works

A **serial** gear train: neighboring gears mesh, so line speed at the pitch circle matches. Angular speeds satisfy **ωᵢ₊₁ = −ωᵢ (Tᵢ/Tᵢ₊₁)**. Intermediate tooth counts cancel in the overall **speed ratio**: **|ω_out/ω_in| = T_first/T_last**. For ideal power (no slip, no losses), **τ_out/τ_in ≈ T_last/T_first** — trade speed for torque.

Key equations

ωᵢ₊₁ = −ωᵢ · (Tᵢ / Tᵢ₊₁),   P = τω ≈ const
