Ganda Baris Tapered Roller Bearings
Bubuka
Baris ganda bantalan roller tapered nyaéta dua jajar bantalan roller tapered, bantalan roller tapered dirancang pikeun tahan duanana gaya radial jeung axial tina beban komposit, utamana dipaké dina stiffness tinggi, operasi kontinyu tina kasempetan, dina spasi kawates sarta perenah kompak bisa nyadiakeun. kinerja stabil.
Fitur sarta Mangpaat
● kapasitas mawa beban High
Bantalan roller tapered baris ganda cocog pikeun beban radial sareng axial beurat.
●beban Axial dina duanana arah
Bantalan roller tapered baris ganda mendakan aci dina dua arah kalayan jarak axial atanapi preload khusus.
● stiffness High
Ganda baris tapered roller arah nyadiakeun susunan bearing kaku.
● Gesekan low
Desain tungtung roller anu dioptimalkeun sareng permukaan permukaan dina flange ngamajukeun formasi pilem pelumas, nyababkeun gesekan anu langkung handap.
● hirup layanan Long
Propil raceway anu dinobatkeun tina bantalan desain dasar sareng profil raceway logaritmik tina bantalan XRL Explorer ngaoptimalkeun distribusi beban sapanjang permukaan kontak, ngirangan puncak setrés dina tungtung roller, sareng ngirangan sensitipitas kana misalignment sareng defleksi aci dibandingkeun sareng profil raceway lempeng konvensional.
●Enhanced reliabiliti operasional
Dioptimalkeun permukaan finish dina surfaces kontak tina rollers na raceways ngarojong formasi film pelumas hydrodynamic.
● Konsistensi tina profil gilinding jeung ukuran
Ieu nyayogikeun distribusi beban anu optimal, ngirangan bising sareng geter, sareng ngamungkinkeun preload diatur langkung akurat.
Struktur jeung Fitur
Bantalan roller tapered ganda-baris gaduh rupa-rupa struktur, anu panggedéna nyaéta jinis 35,000, kalayan cingcin luar raceway ganda sareng dua cingcin jero, sareng spacer antara dua cingcin jero.Clearance tiasa disaluyukeun ku cara ngarobah ketebalan spacer.Jenis bantalan ieu tiasa nanggung beban radial sareng beban axial bidirectional, sareng tiasa ngabatesan kapindahan axial aci sareng perumahan dina kisaran clearance axial bantalan.
Aplikasi
Bantalan roller tapered baris ganda biasana dianggo dina kotak gear, alat angkat, pabrik rolling sareng mesin dina industri pertambangan, sapertos mesin tunneling.
