C, B, and ΔC from m, N, and pressure angle.
Theoretical center distance C = m(N₁ + N₂) / 2. Empirical linear backlash B = 0.04 / DP (DP from metric module: DP = 25.4 / m in teeth per inch). Change in center distance for backlash ΔC = B / (2 tan α); shown converted to mm.
- Center distance C60 mm
- DP (from m)12.7 /in
- Linear backlash B0.08 mm (0.00315 in)
- ΔC for backlash0.1099 mm
Center Distance & Backlash Calculator helps you c, b, and δc from m, n, and pressure angle. It is commonly used by domain specialists, operations teams, learners for gear backlash, center distance, diametral pitch.
