LFR qo'llab -quvvatlovchi rulmanli kirish:
LFR tayanch rulmanining tashqi halqasida U truba bor. U ikki qatorli burchakli aloqa bilyali rulmanga tegishli.
Ushbu seriyali rulman uchun,
- Qo'llab-quvvatlovchi rulmanlar yuqori sifatli rulmanli po'latdan yoki zanglamaydigan po'latdan yasalgan bo'lib, issiqlik bilan ishlov berish va nozik silliqlash orqali qayta ishlanadi va uzoq umr, yuqori sifatli, ko'p maqsadli surtma bilan to'ldiriladi.
- LFR seriyali yo'riqnomali rulmanli rulmanlar chiziqli yo'naltiruvchi rollarda eng ko'p ishlatiladigan, iqtisodiy va amaliy mahsulotlardir. Ular barqaror ishlashi, kichik xatosi, juda past ish shovqini va yuqori ish tezligi bilan silindrli hidoyat raylariga moslashtirilishi mumkin.
- Rulman va yo'naltiruvchi panjara o'rtasidagi aloqa-bu nisbatan yuqori xizmat qilish muddatiga erishish uchun yaxshi aloqa va past ishlash qarshiligiga ega bo'lgan 60 darajali ikki nuqta.
- Rolik ikki qatorli burchakli bilyali rulman va qalinlashgan tashqi halqaning ichki tuzilishi dizaynini qabul qiladi, shunda rulon yuqori yuk tashish quvvatiga ega bo'ladi.
Rulman rulmani eksantrik g'ildirak va konsentrik mil bilan jihozlangan va o'rnatish oson. - Chang o'tkazmaydigan rolik metall chang qoplamasini (KDD) yoki kauchuk sızdırmazlık qopqog'ini (NPP) qabul qiladi.
Rulman xususiyatlari:
1. Yuqori tezlik, past qarshilik, uzoq umr
2. Oddiy va qulay o'rnatish
3. Yumshoq ishlash, kichik xato va juda past ishlaydigan shovqin
