Opat-titik Kontak Ball Bearings
Bubuka
Opat-titik bantalan bola kontak nyaéta radial baris tunggal bantalan bola kontak sudut kalawan raceways nu dirancang pikeun ngarojong beban axial dina duanana arah.Pikeun beban axial tinangtu, beban radial kawates ogé bisa dirojong.Bantalan tiasa dipisahkeun, nyaéta cingcin luar kalayan bal sareng rakitan kandang tiasa dipasang sacara misah ti dua halves ring jero.
Duanana halves ring jero Explorer opat-titik bantalan bola kontak boga taktak recessed.Ieu ngaronjatkeun aliran minyak nalika bearing dipaké dina kombinasi kalayan roller bearing cylindrical.Sajaba ti éta, recesses ieu bisa dipaké pikeun mempermudah dismounting.
Fitur sarta Mangpaat
- ●Accommodates beban axial dina duanana arah
- ●Kurang spasi axial
bantalan ieu nyandak up considerably kirang spasi axial ti bantalan baris ganda. - ● kapasitas mawa beban High
Sajumlah badag bal anu diasupkeun, mere bearing kapasitas mawa beban tinggi na. - ●Desain bisa dipisahkeun
Cingcin jero pamisah ngabalukarkeun gampang ningkatna sarta dismounting of bearing nu. - ● Ningkatkeun flo minyak
- deformasi ring jero kawates lamun subjected kana gaya clamping tinggi.
Fungsi
Nalika ngan ukur beban axial murni anu diterapkeun, bal sareng cincin ngabentuk kontak dua titik anu sanggup nanggung beban axial dua arah.Opat titik kontak bantalan bola téh ok.
Beban torsi bantalan, éta ngagaduhan fungsi bantalan bola kontak sudut sakaligus sareng bantalan bola kontak sudut ganda.Bantalan bola kontak opat-titik tiasa dianggo sacara normal ngan nalika kontak dua titik kabentuk.Ku alatan éta, éta umumna cocog pikeun maranéhanana beban axial murni atawa beban axial badag dina beban komposit dua-titik kontak, opat-titik kontak ball bearing speed wates tinggi, tapi ogé cocog pikeun maranéhanana kali-speed tinggi operasi.
Ciri
Bantalan bola kontak opat titik mangrupikeun struktur anu tiasa dipisahkeun, sareng bantalan tunggal tiasa ngagentos bantalan bola kontak sudut sareng kombinasi payun atanapi kombinasi tukang.
Bisa nanggung beban radial jeung beban axial bidirectional, sarta bisa ngawatesan kapindahan axial dina dua arah, tapi ngawengku spasi axial kirang ti spésifikasi ayeuna ganda baris bearing bola kontak sudut.
Dibandingkeun sareng bantalan bola anu sanés, bantalan bola kontak opat titik gaduh jarak axial anu langkung alit sareng laju wates anu langkung luhur nalika jarak radial sami.
Opat-titik bantalan bola kontak anu cocog pikeun bearing beban axial murni atawa gabungan axial na radial beban dumasar kana beban axial.Alatan cingcin jero ganda-satengah (atawa cingcin luar), jumlah bal ngaronjat sarta kapasitas bearing leuwih badag.
Dina kaayaan kerja normal, jenis ieu bearing bisa ngabentuk sudut kontak nalika bearing beban axial sagala arah, sarta bal baja aya dina kontak jeung raceways jero sarta luar dina hiji titik pikeun nyegah gesekan ngageser badag di wewengkon kontak.Ku alatan éta, bearing teu kudu subjected kana gaya radial jeung beban.
