Podshipnikning ekvivalent dinamik yuki P nima?

The equivalent dynamic load P is a hypothetical constant radial load that would give the same bearing life as the actual combined radial and axial loads. It is calculated as P = X·Fr + Y·Fa, where X and Y are load factors depending on the bearing type and load ratio.

X va Y omillari nima?

X is the radial load factor and Y is the axial load factor. They depend on the bearing type and the ratio Fa/Fr relative to the e-value. When Fa/Fr ≤ e, the axial load has negligible effect (X=1, Y=0). When Fa/Fr > e, both X and Y apply.

Podshipnik hisob-kitoblarida e-qiymat nima?

e-qiymat — har bir podshipnik turiga xos bo'lgan chegara nisbatidir. U o'qiy yuklanishning podshipnik resursiga sezilarli ta'sir ko'rsatadimi yoki yo'qligini aniqlaydi. Fa/Fr nisbati e-qiymatdan oshib ketsa, o'qiy yuklanish hissasini hisobga olish uchun Y koeffitsienti qo'llanilishi lozim.

Toza radial yuklanish holatida qanday harakat qilish kerak?

For pure radial load (Fa = 0), the equivalent load simplifies to P = Fr. No axial factor applies, and you can use the radial load directly in the L10 life calculation.

Buni statik ekvivalent yuklanish P0 uchun ishlatsa bo'ladimi?

Ushbu kalkulyator resurs hisob-kitoblari uchun dinamik ekvivalent yuklanish P ni hisoblaydi. Statik ekvivalent yuklanish P0 uchun formula o'xshash, ammo boshqa X0 va Y0 koeffitsientlardan foydalaniladi. P0 baholash uchun Podshipnik Statik Xavfsizlik Koeffitsienti kalkulyatoridan foydalaning.

Ekvivalent dinamik yuklanma

Podshipnikning ekvivalent dinamik yuklanmasi radial va aksial kuchlarni bitta qiymatga birlashtiradi:

Shart: agar F_a/F_r ≤ e bo'lsa, u holda P = F_r. If F_a/F_r > e bo'lsa, u holda P = X·F_r + Y·F_a.

Amaliy Misol

Misol — Chuqur novli sharli podshipnik 6208

Given: F_r = 8 kN, F_a = 3 kN

F_a/F_r = 3/8 = 0.375 > e = 0.19 → axial load is significant

P = 0.56 × 8 + 2.30 × 3 = 4.48 + 6.90 = 11.38 kN
