yobala kusankha

zinthu Six zokhudzana kubala moyo:

(1) Katundu P [N / mm2] Katundu

Ikuluikulu katundu, wamfupi moyo utumiki wodziwika ndi; wamkulu katundu fluctuation, zazikulu amadza pa moyo akatundu, wamfupi moyo yobala; Mulimonsemo, katundu pazipita sangathe kupitiliza ongolankhula pazipita kololeka katundu. Katundu kukula ndi wofanana leni ntchito katundu akufufuta m'dera ntchito wodziwika ndi, kachitidwe ndi P = F / (D * B).

(2) Liwiro V [m / s] ndi phindu PV

Kuchitira moyo kumadalira phindu PV ya kukula, ndi, enieni katundu P [N / mm2] ndi kutsetsereka mathamangidwe V [m / s] mankhwala, phindu PV n'chochepa, yaitali moyo mwankhanza.

(3) Kutentha T [OC]

Kuchitira moyo komanso amadalira kutentha wodziwika ndi pamene ntchito, kotero kusankha kapangidwe tiyenera kuganizira zigawo zogwirizana makhalidwe kuzirala.

(4) padziko roughness a mbali avale

Roughness wa kukhudzana pamwamba ndi kutenga mbali pa akupera ayenera kukhala pakati Ra0.2 ~ Ra0.8, wodziwika ndi msonkhano ndi ntchito za ndondomeko simungakhoze kukhala lakuthwa TV kuwononga kuchitira pamwamba.

(5) padziko chuma cha mbali akupera, pamwamba roughness a mbali akupera chinthu moyo wa utumiki wa bushings, pansi bwinobwino zinthu padziko chofunika ≤ 0.4μm akuti ka.

(6) zinthu zina monga kapangidwe zimakhudza mpando zinthu kondomu.
