Iwo anonzi precision bearing anoreva kurongeka zvinoenderana neISO kupatsanura: P0, P6, P5, P4, P2.Iwo mamakisi anowedzerwa zvakatevedzana, ayo P0 iri yakajairika chaiyo, uye mamwe mamakisi ari chaiwo mamakisi.Mabearings akajairika ndiwo mabhengi edu anowanzo shandiswa.Ndeupi mutsauko uripo pakati pemabhengi chaiwo nemabhengi akajairwa?Zvinoenderana nekunzwisisa kwakadzama, isu tichasuma mutsauko pakati pemabhengi chaiwo nemabhengi akajairwa.

Ndeupi mutsauko uripo pakati pemabhengi chaiwo nemabhengi akajairwa?

Kurongeka kwacho kwakasiyana nebererowo zvayo.1. The dimensional zvinodiwa zvakasiyana.The dimensional deviation (yemukati dhayamita, kunze dhayamita, ellipse, etc.) yechigadzirwa nehupamhi hwepamusoro giredhi idiki pane kukosha kunodiwa nechigadzirwa chine yakaderera giredhi;

Kurongeka kwacho kwakasiyana nebererowo zvayo.2. Kukosha kunodiwa kwekutenderera kutenderera kwakasiyana.Chigadzirwa chine hunyanzvi hwepamusoro chine kutenderera kwepamusoro (yemukati radial runout, kunze radial runout, kuguma kutarisana nemujaho wekumhanya, nezvimwewo) pane zvigadzirwa zvine yakaderera giredhi.Iko kukosha kunodiwa kwakasimba;

Kurongeka kwacho kwakasiyana nebererowo zvayo.3. Chimiro chepamusoro uye chimiro chepamusoro zvakasiyana.Chimiro chepamusoro uye pamusoro pemhando yezvigadzirwa zvine giredhi yakanyatsojeka (kushata kwepamusoro, kutsauka kwedenderedzwa, kutsauswa kwegorofu, nezvimwewo zvemujaho kana chiteshi) Zvigadzirwa zvakaderera pane nhanho yechokwadi zvinoda hunhu hwakaomarara;

Precision mabearings akasiyana nemabhengi akajairwa.4. Zvigadzirwa zvine magiredhi emhando yepamusoro zvakanyanya kunaka pane zviya zvemagiredhi chaiwo.

Mukuita kwekushandisa faniro, iyo chaiyo inotakura kana yakajairwa kutakura inosarudzwa zvinoenderana nechaicho chinodiwa, kuitira kuti mechanical mudziyo kana chikamu chinogona kushandiswa zviri nani.
