Qisqa Tasvir:

● Silindrsimon ichki teshik va konusning ichki teshiklari ikkita tuzilishga ega.

●Yilni tuzilish, katta qat'iylik, katta yuk ko'tarish qobiliyati va yuk yukidan keyin kichik deformatsiyaning afzalliklariga ega.

●Oson o'rnatish va demontaj qilish uchun bo'shliqni biroz sozlashi va joylashishni aniqlash moslamasining tuzilishini soddalashtirishi mumkin.


Mahsulot detali

Mahsulot teglari

Kirish

Ikki qatorli silindrsimon rulmanlar mil va rulman poydevori o'rtasida ma'lum bir eksenel siljish imkonini beradi va joylashtirmaydigan rulmanlar sifatida ishlatilishi mumkin. Bunday rulman ixcham tuzilish, katta qattiqlik, katta yuk ko'tarish qobiliyati, yuklanganidan keyin kichik deformatsiyaning afzalliklariga ega. va boshqalar, ayniqsa, dastgoh milini qo'llab-quvvatlash uchun javob beradi.

Xususiyatlari va afzalliklari

● Yuqori yuk ko'tarish qobiliyati

Ikki qatorli silindrsimon rulmanlar ikkinchi qatorli roliklar tufayli og'ir radiusli yuklarga mos keladi.

● Kam ishqalanish (rolik uchi / gardish aloqa joyi)

Ochiq gardish dizayni, rolikli uchi dizayni va sirt qoplamasi bilan birga, moylash plyonkasi shakllanishiga yordam beradi, bu esa ishqalanishni kamaytiradi va eksenel yukni ko'tarish qobiliyatini oshiradi.

● Uzoq xizmat muddati

Logarifmik rolik profili rolik/poyga yoʻli aloqasidagi chekka kuchlanishlarni va notoʻgʻri hizalanish va milning burilishiga sezuvchanlikni kamaytiradi.

● Kengaytirilgan operatsion ishonchlilik

Roliklar va yo'laklarning aloqa yuzalarida sirt qoplamasi gidrodinamik moylash plyonkasi shakllanishini qo'llab-quvvatlaydi.

● Ajraladigan va almashtiriladigan

Ikki qatorli silindrsimon rulmanlarning ajraladigan qismlari bir-birini almashtiradi.Bu o'rnatish va demontaj qilishni, shuningdek, texnik xizmat ko'rsatishni tekshirishni osonlashtiradi.

● Yuqori tezlik qobiliyati

Qafas dizaynlari yuqori tezliklar, tez tezlashishlar va eng yuqori yuklarga mos keladi.

Ilova

NUU ikki qatorli silindrsimon rulmanlar dastgohlar, avtotransport vositalari, motorlar, reduktor reduktorlari, tebranish ekranlari va boshqalarda qo'llanilishi mumkin.

Foydalanish

Ikki qatorli silindrsimon rulman lamel yo'nalishda katta yukni ko'tarishi mumkin.Bu yuqori tezlikda rulmandagi ikki qatorli DAO roliklarini o'zaro bog'liq holda joylashtirish imkonini beradi.Aylanish paytida tebranish chastotasi bitta qatorli rulmandan ikki baravar yuqori va amplituda 70% ga kamayadi.

Umumiy foydalanishda ikki turdagi rulmanlar mavjud: NN30/W33 va NN30K/W33 seriyali.NNU49/W33 va NNU49K/W33 seriyali rulmanli tashqi halqali chetiga, ichki halqasini ajratish mumkin, NN30K/W33 va NNU49K/W33 seriyali ichki halqa shpindelning konusli jurnaliga mos keladigan konusli teshiklardir (konus 1:12). .Ichki halqaning eksenel harakati rulman bo'shlig'ini kamaytirish va hatto rulmanni oldindan siqish uchun ichki halqani kengaytirishi mumkin.

Silindrsimon rulmanlar odatda issiq yuklanadi va rulman bo'shlig'ini kamaytirish yoki oldindan yuklash maqsadiga erishish uchun shovqin moslamasi ishlatiladi.Echib olinadigan ichki halqali NNU49 seriyali podshipniklar, odatda, milning yuqori aylanish aniqligini olish uchun shpindelni ichki halqaga o'rnatgandan so'ng, poyga yo'lida ishlov beriladi.
