Tavsiya etilgan o'tirish turlari
Umumiy tamoyil
Aylanuvchi yuklamaga duchor bo'lgan halqa siljishning oldini olish uchun qattiq o'tirishga ega bo'lishi kerak. Statsionar yuklamali halqa montaj qulayligi va o'qiy siljish uchun bo'shroq o'tirishga ega bo'lishi mumkin.
Val uchun o'tirish tavsiyalari (aylanuvchi ichki halqa)
| Load | Ball Bearings | Rolikli podshipniklar | Fit Type |
|---|---|---|---|
| Yengil / o'zgaruvchan yo'nalish | j5, j6 | j5, j6 | Transition |
| Normal | k5, k6 | m5, m6 | O'tish / Yengil siqish |
| Heavy / shock | m5, m6 | n6, p6 | Interference |
Korpus uchun o'tirish tavsiyalari (statsionar tashqi halqa)
| Condition | Locating | Non-locating | Fit Type |
|---|---|---|---|
| Normal loads | J7, H7 | H7, G7 | Siljuvchi / o'tish |
| Heavy loads | K7, M7 | H7, J7 | Transition |
| Yengil, oson demontaj | H7 | G7, F7 | Clearance |
| Aylanuvchi tashqi halqa | M7, N7 | K7, M7 | Interference |
ℹ️ Tip: Teshik diametri d > 100 mm bo'lgan podshipniklar uchun nisbiy siqishning pastligi sababli ko'pincha keyingi qattiqroq tolerans sinfi tavsiya etiladi. Kovak vallarda ham qattiqroq o'tirish talab etiladi.
⚠️ Note: Bular umumiy tavsiyalardir. O'z ilovangiz uchun har doim tegishli podshipnik ishlab chiqaruvchisining (SKF, FAG/Schaeffler, NSK, Timken) ko'rsatmalarini tekshiring.
