Koyi game da ƙa'idodin radial clearance don birgima bearings

Bearingsharewa yana nufin adadin motsi lokacin da ba a sanya bearing a cikin shaft ko akwatin bearing ba, an gyara gefe ɗaya na zoben ciki ko zoben waje, sannan gefen da ba a gyara ba yana motsawa ta radial ko axial. Dangane da alkiblar motsi, ana iya raba shi zuwa radial clearance da axial clearance. Sharewa kuma yana da matukar muhimmanci ga amfani da bearings.

Radial clearance na birgima bearing shine ma'aunin lissafi na nisan radial na zoben waje dangane da zoben ciki daga matsayin iyaka mai daidaituwa na radial zuwa matsayin iyaka akasin haka a cikin yanayin da ba a riga an ɗora ba. Dangane da ma'aunin ƙasa na GB/T307.1-2018, an raba radial clearance zuwa maki biyar: babba, matsakaici, ƙanana, ƙanana sosai da ƙarami. Ƙimar sharewa na kowane kewayon maki sune kamar haka: C2, CN, C3, C4, C5; C0, C1, C2, CN; Ƙarami ga C0, C1, C2, CN; Mafi ƙarancin shine C0 da C1; Ƙarin ƙanana sune C0 da C1, inda C0 ke wakiltar ƙaramin sharewa kuma C5 yana wakiltar babban sharewa.
