Paano kinakalkula ang torque ng ball screw?

T = F*lead/(2*pi*eta), eta tungkol sa 0.90 para sa ball screws.

Anong kahusayan ang para sa mga ball screw?

0.85-0.95, karaniwang 0.90. ACME lead screws: 0.25-0.50.

Paano maiiwasan ang kritikal na bilis?

Mag-operate sa ibaba ng 80% ng Ncrit. Gumamit ng mas malaking diameter, mas maikling haba, at mas mahusay na end fixity.

Ano ang nakakaapekto sa buhay?

L10 = (Ca/F)^3 x 10^6 rev. Load cubed inverse relationship.

Fixed-fixed: 4.73. Fixed-supported: 3.93. Supported-supported: 3.14.

Ball Screw Calculator — Torque, Critical Speed & Life

Enter lead, nominal diameter, axial load, and speed to calculate drive torque, efficiency, critical speed, and rated life. Calculations are based on general ball-screw engineering practice and manufacturer-catalogue methods; ball screw terminology and acceptance tolerances are defined in the ISO 3408 standard series.
