hali selection

Shida dalilai alaka qazanta rayuwa:

(1) Load P [N / mm2] Load

The fi girma da kaya, da gajeriyar da sabis rai na hali. da girma kaya shakka, mafi girma da tasiri a kan hali rayuwa, gajeriyar hali rayuwa; a wani hali, matsakaicin kaya ba zai iya wuce da msar tambayar iyakar canja kaya. Load size ne daidai da ainihin aikin kaya raba da kimanta yankin na hali, da dabara ne P = F / (D * B).

(2) Gudu V [m / s] da kuma PV darajar

Qazanta rayuwa dogara a kan PV darajar da size, wato, da ainihin kaya P [N / mm2] da zamiya gudu V [m / s] samfurin, PV darajar ne karami, da ya fi tsayi cikin hali rayuwa.

(3) Temperatuur T [OC]

Qazanta rayuwa shi ne dogara da yawan zafin jiki na hali a lokacin da amfani da, don haka a cikin zane selection kamata la'akari da dacewa aka gyara na da sanyaya halaye.

(4) surface roughness na lalacewa sassa

Roughness na lamba surface tare da hali a kan nika sassa kamata a tsakanin Ra0.2 ~ Ra0.8, qazanta da taro da kuma yin amfani da tsari ba zai iya yi kaifi kafofin watsa labarai lalacewar da hali surface.

(5) da surface abu na nika sassa, da farfajiya roughness na nika sassa ne mai factor shafi sabis rai na bushings, a karkashin al'ada hali a surface bukata ≤ 0.4μm ka.

(6) wasu dalilai kamar hali wurin zama zane, lubrication yanayi.
