Val tekislashning asoslari
Val tekislash — ulangan mashinalarning aylanish o'qlari ish sharoitida bir to'g'ri chiziqda joylashishini ta'minlaydi. Noto'g'ri tekislash — aylanuvchi mexanizmlarda podshipnik va muhrlarning muddatidan oldin ishdan chiqishining eng keng tarqalgan sababi.
Noto'g'ri tekislash turlari
- Siljish (parallel) — val o'qlari parallel, lekin bir-biridan siljigan. Muftada mm da o'lchanadi.
- Angular — val o'qlari bir burchak ostida kesishadi. mm/100mm yoki milliradianlarda (mrad) o'lchanadi.
Aylanish tezligiga ko'ra tolerans ko'rsatkichlari
The rpm-stepped values below are widely used industry rules of thumb that originate from laser shaft-alignment practice (tolerance tables published by alignment-system manufacturers such as Prüftechnik and Fixturlaser); they are not defined by an ISO standard. Coupling standards such as ISO 14691 (flexible couplings for general-purpose applications in petroleum, petrochemical and natural gas industries) specify coupling requirements, including misalignment capability — always defer to the coupling manufacturer’s data.
| Speed Range | Offset (mm) | Burchak (mm/100mm) |
|---|---|---|
| ≤ 750 RPM | 0.10 | 0.15 |
| 750 – 1500 RPM | 0.08 | 0.10 |
| 1500 – 3000 RPM | 0.05 | 0.07 |
| 3000 – 6000 RPM | 0.03 | 0.04 |
| > 6000 RPM | 0.02 | 0.03 |
Mufta turiga qarab tuzatishlar
- Umumiy egiluvchan — asosiy tolerans (×1.0)
- Moslashuvchan yuqori samarali — qattiqroq (×0.5)
- Rigid coupling — strictest (÷2, equivalent to ×0.5)
Amaliy Misol
Given: Speed = 1500 RPM, Coupling = Flexible general, Spacer = 100 mm
Speed range: 750–1500 RPM → Offset = 0.08 mm, Angular = 0.10 mm/100mm
Muftani tuzatish: ×1.0 (moslashuvchan umumiy)
Siljish toleransi = 0.08 mm
Burchak toleransi = 0.10 mm/100mm = 1.00 mrad
Gap difference at spacer = 0.10 × 100/100 = 0.10 mm
⚠️ Note: Bular umumiy sanoat ko'rsatmalari. Har doim mufta ishlab chiqaruvchisining texnik shartlarini tekshiring — aniq konstruksiyaga qarab ular qattiqroq yoki bo'shroq bo'lishi mumkin. Issiq rejimda ishlaydigan mashinalarda issiqlik kengayishini inobatga oling.
