What formula is used?

T=4×10^-6 k L^2 f^2 for T in newtons, metre weight k in kg/m, free span L in mm and fundamental frequency f in hertz, as published in the Optibelt V-belt technical manual.

Does the result define the correct installation tension?

No. It estimates the tension corresponding to the measured span frequency. The required target must come from the exact belt product and drive design.

Why was the deflection-force method removed?

A manufacturer force-deflection procedure compares force at a specified deflection with product-specific data. The former ideal-string equation did not account for belt axial and bending stiffness and could not generally infer installed static tension.

Which frequency should be entered?

Use the measured fundamental transverse frequency of the specified free unloaded span under the instrument and product procedure, not an arbitrary spectral peak.

Can the same generic limits be used for every belt?

No. Target frequency or tension depends on belt product, width or belt count, span, drive geometry, power and installation state.

Hubungan frekuensi

T = 4 × 10⁻⁶ × k × L² × f²

T — tegangan statik rentang tali sawat (N)
k — berat per meter tali sawat yang tepat (kg/m)
L — panjang rentang berayun bebas (mm)
f — frekuensi asas yang diukur (Hz)

Hubungan ini bersamaan dengan frekuensi asas tali tegang ideal f=(1/(2L))√(T/k), dengan faktor unit bagi L dalam milimeter. Kekakuan tali sawat sebenar dan keadaan pengukuran boleh menyebabkan sisihan kecil; gunakan prosedur pengeluar dan berat per meter sebenar.

Contoh pengesahan yang diterbitkan

Optibelt memberikan k=0.377 kg/m, L=2189.3 mm dan f=14.33 Hz, menghasilkan T=1484.24 N (kira-kira 1484 N).
