Reduktor moyi to'ldirish hajmi kalkulyatori
Sanoat reduktorlari uchun yog' miqdorini baholash. Tishli, qiya tishli, konus, qurt va sayyoraviy reduktor turlarini qo'llab-quvvatlaydi. Haroratga bog'liq yog' sathi, issiqlik kengayishi, almashtirish intervali va yog' og'irligi.
Moy hajmi & texnik shartlar
Empirik moy hajmi formulasi
Where k turga bog'liq koeffitsient, a o'q oralig'i (m), b — yuz kengligi (m). Ko'p bosqichli: har bir qo'shimcha bosqich birinchi bosqich hajmining ~70% ini qo'shadi.
| Gearbox Type | Factor k | Fill Ratio | VG Grade |
|---|---|---|---|
| Spur / Helical | 0.50 | 1/3 housing | VG 220 |
| Bevel | 0.60 | Per marks | VG 220–320 |
| Worm | 0.80 | To worm center | VG 320–460 (PAG) |
| Planetary | 0.35 | 1/3–1/2 korpus | VG 150–220 |
| Hypoid | 0.65 | Per marks | VG 220–320 (EP) |
Moylash moyining issiqlik kengayishi
Mineral oil expansion coefficient β ≈ 0.0007/°C. Synthetic PAO similar. This means ~7% expansion per 100°C rise.
Amaliy Misol
V₁ = 0.50 × 0.200² × 0.060 × 1000 = 1.20 L
V_total = 1.20 + 1.20 × 0.70 = 2.04 L
Oil weight = 2.04 × 0.87 = 1.77 kg
At 70°C (vs 15°C fill): V_hot = 2.04 × (1 + 0.0007 × 55) = 2.12 L (+79 mL)
Moyni almashtirish muddati bo'yicha ko'rsatmalar
| Oil Type | Normal (≤70°C) | Warm (70-90°C) | Hot (>90°C) |
|---|---|---|---|
| Mineral (VG 220) | 8,000–10,000 h | 4,000–6,000 h | 2,000–3,000 h |
| Semi-synthetic | 12 000–15 000 soat | 6,000–10,000 h | 3,000–5,000 h |
| To'liq sintetik (PAO) | 15 000–20 000 soat | 10 000–15 000 soat | 5,000–8,000 h |
| PAG (qurt uzatmalari) | 20 000–30 000 soat | 12 000–18 000 soat | 6,000–10,000 h |
