To'rt nuqtali kontaktli rulmanlar
Kirish
To'rt nuqtali kontaktli rulmanlar har ikki yo'nalishda ham eksenel yuklarni qo'llab-quvvatlash uchun mo'ljallangan, radiusli bir qatorli burchakli kontaktli rulmanlardir.Berilgan eksenel yuk uchun cheklangan radial yuk ham qo'llab-quvvatlanishi mumkin.Rulmanlar ajratilishi mumkin, ya'ni sharli va qafasli yig'ma tashqi halqa ikkita ichki halqa yarmidan alohida o'rnatilishi mumkin.
Explorer to'rt nuqtali kontaktli sharli podshipniklarining ikkala ichki halqa yarmida yelkalari chuqurlashtirilgan.Bu rulman silindrsimon rulman bilan birgalikda ishlatilganda yog 'oqimini yaxshilaydi.Bundan tashqari, bu chuqurchalar demontajni osonlashtirish uchun ishlatilishi mumkin.
Xususiyatlari va afzalliklari
- ●Ikkala yo‘nalishda ham eksenel yuklarni qabul qiladi
- ●Kamroq eksenel bo'shliq
Ushbu podshipniklar ikki qatorli podshipniklarga qaraganda ancha kam eksenel joy egallaydi. - ●Yuqori yuk ko'tarish qobiliyati
Ko'p sonli to'plar o'rnatilgan bo'lib, bu rulmanga yuqori yuk ko'tarish qobiliyatini beradi. - ●Ajraladigan dizayn
Ajratilgan ichki halqa rulmanni o'rnatish va tushirishni osonlashtiradi. - ●Yaxshilangan yog 'fl
- Yuqori siqish kuchlari ta'sirida cheklangan ichki halqa deformatsiyasi.
Funktsiya
Faqat sof eksenel yuklar qo'llanilganda, to'p va halqa ikki tomonlama eksenel yuklarni ko'tarishga qodir bo'lgan ikki nuqtali kontaktni hosil qiladi.To'rt nuqta kontaktli rulmanlar yaxshi.
Rulman momentli yukni ko'tarib, u bir qatorli burchakli aloqa bilyali rulman va ikki qatorli burchakli aloqa bilyali rulman funktsiyalariga ega.To'rt nuqtali kontaktli rulman faqat ikkita nuqta aloqasi hosil bo'lganda normal ishlashi mumkin.Shuning uchun, u odatda ikki nuqtali kontaktli kompozit yuk ostida sof eksenel yuk yoki katta eksenel yuk uchun javob beradi, to'rt nuqtali kontaktli rulman chegara tezligi yuqori, lekin ayni paytda yuqori tezlikda ishlaydigan holatlar uchun ham javob beradi.
Xususiyatlari
To'rt nuqtali kontaktli rulman ajraladigan tuzilma bo'lib, bitta rulman burchakli aloqa bilyali rulmanni oldingi birikma yoki orqa kombinatsiya bilan almashtirishi mumkin.
U radial yukni va ikki tomonlama eksenel yukni ko'tarishi mumkin va eksenel joy almashishni ikki yo'nalishda cheklashi mumkin, ammo u joriy spetsifikatsiyaga qaraganda ikki qatorli burchakli kontaktli rulmanga qaraganda kamroq eksenel joyni egallaydi.
Boshqa rulmanli rulmanlar bilan solishtirganda, to'rt nuqtali kontaktli rulmanlar kichikroq eksenel bo'shliqqa va radial bo'shliq bir xil bo'lganda yuqori chegara tezligiga ega.
To'rt nuqtali kontaktli rulmanlar sof eksenel yuklarni yoki eksenel yuklarga asoslangan birlashtirilgan eksenel va radial yuklarni ko'tarish uchun javob beradi.Ikkita yarim ichki halqa (yoki tashqi halqa) tufayli to'plar soni ortadi va yuk ko'tarish qobiliyati kattaroqdir.
Oddiy ish sharoitida, bu turdagi rulman har qanday yo'nalishda eksenel yukni ko'tarishda aloqa burchagini hosil qilishi mumkin va po'lat to'p aloqa sohasida katta surma ishqalanishiga yo'l qo'ymaslik uchun bir nuqtada ichki va tashqi poyga yo'llari bilan aloqa qiladi.Shuning uchun rulman radial kuchlar va yuklarga ta'sir qilmasligi kerak.
