Kailan gagamitin ang splines kumpara sa keys?

Ang splines ay para sa mas mataas na torque, self-centering, at sliding connections. Ang keys ay para sa mas simpleng aplikasyon na mas mababang gastos.

Ano ang epekto ng pressure angle?

30 degrees standard. Mas mataas na mga anggulo ay nagbibigay ng mas malakas na mga ngipin ngunit mas malaking radial force.

Anong load distribution factor?

K=0.75 para sa fixed splines, K=0.5 para sa sliding under load.

Gaano katagal dapat ang engagement?

0.75D hanggang 1.25D pitch diameters.

Anong mga materyales ang pinakamaganda?

Case-hardened alloy steel na 58-62 HRC para sa mabibigat na karga.

Spline Connection Calculator — ISO 4156

Involute spline geometry per ISO 4156 (metric module, side fit). Enter module, number of teeth, pressure angle, engagement length, and torque for a simplified bearing-stress and torque-capacity estimate — a common design practice, not part of ISO 4156.

Simplified Spline Bearing-Stress Estimate

where h = effective tooth height (approx 0.9m), z = teeth, L = engagement length, K = load distribution factor, Dp = pitch diameter.

Pamamahagi ng karga: K=0.75 fixed, K=0.5 sliding under load. Ginagamit ng calculator na ito ang K=0.75.

Note: ISO 4156 defines involute spline geometry, tolerances, fits and inspection — it does not specify a load-capacity method. The bearing-stress, torque-capacity and safety-factor results above are a simplified engineering estimate (uniform load sharing, effective tooth height h ≈ 0.9m, empirical factor K) commonly used in design practice; they do not constitute ISO 4156 compliance. Verify critical designs with detailed analysis.
