Ganda Baris Cylindrical Roller Bearings
Bubuka
Ganda-baris cylindrical roller arah ngawenangkeun kapindahan axial tangtu antara aci jeung titincakan bearing sarta bisa dipaké salaku non-positioning bearing.This jenis bearing boga kaunggulan struktur kompak, rigidity badag, kapasitas bearing badag, deformasi leutik sanggeus loading. , jsb, utamana cocog pikeun rojongan spindle alat mesin.
Fitur sarta Mangpaat
● kapasitas mawa beban High
Kusabab baris kadua maranéhanana rollers, ganda baris cylindrical roller bearing cocog pikeun beban radial beurat.
● Low gesekan (Roller tungtung / aréa kontak flange)
Desain flange kabuka, babarengan jeung desain tungtung roller jeung finish permukaan, ngamajukeun formasi pilem pelumas hasilna gesekan handap sarta kapasitas mawa beban axial luhur.
● hirup layanan Long
Propil roller logaritmik ngurangan stresses ujung dina roller / kontak raceway jeung sensitipitas kana misalignment sarta deflection aci.
● ditingkatkeun reliabiliti operasional
Permukaan permukaan dina permukaan kontak tina rollers na raceways ngarojong formasi film pelumas hidrodinamik.
● Bisa dipisahkeun jeung ditukeurkeun
Komponén anu tiasa dipisahkeun tina bantalan roller silinder baris ganda tiasa ditukeurkeun.Ieu ngagampangkeun pamasangan sareng dismounting, ogé pamariksaan pangropéa.
● kamampuhan speed High
Desain kandang anu cocog pikeun speeds tinggi, akselerasi gancang sarta beban puncak.
Aplikasi
Bantalan roller silinder baris ganda NUU tiasa dianggo dina alat mesin, kendaraan motor, motor, kotak gear réduksi, layar geter, jsb.
Pamakéan
Baris ganda roller bearing cylindrical bisa nanggung beban du badag dina arah radial.Hal ieu ngamungkinkeun dua jajar rollers DAO dina bearing kalawan speed tinggi bisa disusun dina cara cross.Frékuénsi turun naek salila rotasi dua kali leuwih luhur ti bearing baris tunggal, sarta amplitudo diréduksi ku 70%.
Aya dua jinis bantalan anu biasa dianggo: séri NN30 / W33 sareng NN30K / W33.NNU49 / W33 na NNU49K / W33 runtuyan bearing cingcin luar jeung ujung, cingcin jero bisa dipisahkeun, NN30K / W33 na NNU49K / W33 ring jero runtuyan anu tapered liang (taper 1:12), nu cocog sareng jurnal conical tina spindle nu .Gerakan Axial tina cingcin jero bisa nyieun ring jero dilegakeun pikeun ngurangan bearing clearance komo pretighten bearing nu.
bantalan bore cylindrical biasana panas-sarat, sarta gangguan fit dipaké pikeun ngurangan bearing clearance atawa pikeun ngahontal tujuan preloading.bantalan runtuyan NNU49 kalawan ring jero pisah umumna machined on raceway sanggeus masang spindle on ring jero pikeun ménta akurasi rotasi spindle tinggi.
