Timing Belt Calculator

Kalkulahin ang haba ng timing belt sa mga pitch at bilang ng ngipin. Sinusuportahan ang HTD 3/5/8/14 at GT2/GT3/GT5 na mga profile. Ilagay ang ngipin ng pulley, center distance, at pitch.

Halimbawa — HTD-5M Belt

Given: z₁=20, z₂=60, pitch=5 mm, C=200 mm

d₁ = 20×5/π = 31.83 mm, d₂ = 60×5/π = 95.49 mm

L_mm = 2×200 + π(31.83+95.49)/2 + (95.49-31.83)²/(4×200) = 400 + 200.0 + 5.1 = 605.1 mm

Belt teeth = 605.1/5 = 121.0 → nearest standard (even) catalogue size: 122 ngipin (610 mm belt), then re-check the actual center distance
