Juftlikdagi burchakli aloqa rulmanlarini yig'ish

Angular Contact Ball Bearing in pair

Burchakli aloqa rulmanlari ham radial, ham eksenel yuklarga bardosh bera oladi. Ular yuqori tezlikda ishlashlari mumkin. Aloqa burchagi qanchalik katta bo'lsa, eksenel yukni ko'tarish qobiliyati shuncha yuqori bo'ladi. Yuqori aniqlik va yuqori tezlikli rulmanlar odatda 15 daraja aloqa burchagini oladi. Eksenel kuch ostida aloqa burchagi ortadi. Bir qatorli burchakli aloqa rulmanlari faqat bitta yo'nalishda eksenel yuklarga bardosh bera oladi va radiusli yuklarga tushganda qo'shimcha eksenel kuchlarni keltirib chiqaradi.

Va ular faqat mil yoki korpusning eksenel siljishini bir yo'nalishda cheklashlari mumkin. Agar burchakli aloqa podshipniklari juft-juft qilib o'rnatilsa, juft rulmanning tashqi halqalari qarama-qarshi, ya'ni keng uchi keng uchiga, tor uchi esa tor uchiga qaragan. Bu qo'shimcha eksenel kuchlarni keltirib chiqarmaydi va milni yoki korpusni har ikki yo'nalishda ham eksenel o'ynashni cheklaydi.

Chuqur trubkali rulman milga o'rnatilgandan so'ng, milning yoki korpusning eksenel siljishini rulmanning eksenel oralig'ida cheklash mumkin, shunda eksenel joylashishni har ikki yo'nalishda ham bajarish mumkin. Chuqur yivli rulman katta radiusli bo'shliqqa ega bo'lganda, u burchakli aloqa rulmanining ishlashiga ega va katta eksenel yukga bardosh bera oladi.

Chuqur trubkali rulmanlar katta eksenel yuklarga ega bo'lgan yuqori tezlikda ishlaydigan sharoitlarda rulmanlardan ustundir. Bunga qo'shimcha ravishda, ushbu turdagi rulmanlar ham o'zlarini moslashtirish qobiliyatiga ega. Nishab bo'lganda 2' ~ 10' korpusning teshigiga kelsak, u hali ham normal ishlashi mumkin, ammo rulmaning ishlash muddatiga ma'lum darajada ta'sir qiladi.

Nega burchakli aloqa rulmanlari ko'pincha juftlikda ishlatiladi?

Burchakli aloqa podshipniklari yon tomonga yo'naltirilishi mumkin, lekin faqat bitta yo'nalishda. Agar tortish yo'nalishi ma'lum bo'lsa va agar muhim bo'lsa, tortish podshipnikini tanlash kerak bo'ladi. Ammo yon bosish katta bo'lmasa (GG lt; 30%), lekin ikki tomonlama (masalan, qatlam yoki yukni teskari aylantirish) juft burchakli podshipniklar ikkala tomonga burilishlarni boshqarish uchun tanlovdir.

Burchakli aloqa yotqizgichi, radiusli yotoq va to'rtta kontaktli yotoq o'rtasidagi farq nimada?

Farqi - oluklarning turli shakllari. Yupqa qismli burchakli aloqa rulmanlari (A turi) uchun yugurish yo'li va po'lat sharlar burchak bilan aloqa qiladi. Yugurish radiusi markazi po'lat sharlarning markaz chizig'idan chetga chiqib, nosimmetrik tarzda markaz chizig'i atrofida taqsimlanadi, yupqa uchastkali radiusli aloqa rulmanlari (C turi) uchun markaziy chiziq radiusining markazi po'latdan yasalgan to'plardan. Yupqa uchli to'rtburchak kontaktli rulmanlar uchun (X turi), yo'lning har ikki tomonida yugurish yo'lining radiusining ikkita markazi mavjud va ikkalasi ham po'latdan yasalgan sharlarning markaziy chizig'idan chetga chiqadi, bu esa to'rtburchakning to'rtburchak kontaktli to'pi Rulmanlar (X turi) tezyurar va temir sharlar o'rtasida to'rtta nuqtali aloqa hosil qilish uchun.
