- Kev suav cov qauv ntawm cov yeeb nkab steel siab bearing muaj peev xwm thiab phab ntsa thickness:
Siab=(phab ntsa thickness × 2 × steel yeeb nkab khoom tensile lub zog) / (sab nraud txoj kab uas hla * coefficient)
Cov yeeb nkab steel siab coefficient tau hais los saum toj no tsis yog tus nqi ruaj khov, nws hloov pauv raws li qhov tseeb siab-kev muaj peev xwm ntawm cov yeeb nkab tooj liab. Cov hauv qab no yog lub ntsiab txhais ntau yam ntawm steel yeeb nkab siab coefficient:
Thaum lub siab P<7Mpa, the coefficient is S=8;
Thaum 7
When the pressure P>17.5, tus coefficient yog S =4.
