Podshipnikning statik xavfsizlik koeffitsienti s0 nima?

Statik xavfsizlik koeffitsienti s0 — bu asosiy statik yuklanish reytingi C0 ning haqiqiy statik ekvivalent yuklanish P0 ga nisbati. U podshipnikni statik yoki zarbali yuklanishlar ostida doimiy deformatsiyalanishdan himoya qilishini ta'minlaydi. s0 = C0 / P0.

s0 ning tavsiya etilgan minimal qiymati qancha?

Minimum s0 depends on the application: s0 ≥ 1.0 for normal quiet operation with ball bearings, s0 ≥ 1.5 for roller bearings under normal loads, s0 ≥ 2.0 for shock loads or vibrating equipment, and s0 ≥ 3.0 for high reliability or safety-critical applications.

Agar s0 juda past bo'lsa nima bo'ladi?

Agar s0 tavsiya etilgan minimal qiymatdan past bo'lsa, podshipnikda yumalanish yo'llarida doimiy botiqliklar (brinellash) paydo bo'lishi mumkin. Bu esa shovqin, tebranish va muddatidan oldin charchash natijasida ishdan chiqishning ortishiga olib keladi.

Statik ekvivalent yuklanish P0 ni qanday aniqlash mumkin?

For radial bearings: P0 = X0·Fr + Y0·Fa, or P0 = Fr (whichever is larger). For thrust bearings: P0 = Fa + 2.3·Fr·tan(α). The factors X0 and Y0 depend on the bearing type.

s0 aylanuvchi podshipniklarga tatbiq etiladi?

s0 asosan statik yoki juda sekin aylanish sharoitlari uchun mo'ljallangan (n < 10 RPM), yoki ish vaqtidagi zarb/ta'sir yuklanishlari uchun. Oddiy aylanish sharoitlari uchun esa dinamik yuklanish reytingi C va charchoq resursi L10 qo'llaniladi.

Statik xavfsizlik koeffitsienti

ISO 76 ga muvofiq, statik xavfsizlik koeffitsienti asosiy statik yuk ko'rsatkichining haqiqiy statik ekvivalent yukka nisbatidan iborat:

C₀ — asosiy statik yuk ko'rsatkichi (kN), podshipnik katalogidan
P₀ — statik ekvivalent yuk (kN), haqiqiy radial & aksial kuchlardan hisoblanadi

Minimum s₀ Tavsiyalar

Application	Ball Bearings	Rolikli podshipniklar
Past shovqin / silliq ishlash	≥ 2.0	≥ 3.0
Oddiy jim ishlash	≥ 1.0	≥ 1.5
Tebranishli / zarba yuklari	≥ 1.5	≥ 2.0
Yuqori ishonchlilik / xavfsizlik	≥ 2.0	≥ 3.0
Engil yuk, qo'l bilan aylantirish	≥ 0.5	≥ 1.0

Amaliy Misol

Misol — 6208 chuqur egli sharli podshipnik

Given: C₀ = 31.5 kN, P₀ = 12 kN, normal ishlash rejimi

s₀ = 31.5 / 12 = 2.63

Minimal talab: s₀ ≥ 1.0 → PASS (margin +163%)

ℹ️ Tip: Ishlash davomida zarbli yuklarga duchor bo'luvchi podshipniklar uchun (masalan, jag'li maydalagichlar, vibratsiyali elaklar) dinamik xizmat muddatini hisoblashga qo'shimcha ravishda s₀ ni ham tekshiring.
