Halaye na, menene siraran sashe?

Siraran sashe bearingssuna da sashin ɗaukar kaya mai siriri sosai, wanda ke ba da damar rage yawan samfura da sauƙin amfani, kuma yana faɗaɗa kewayon aikace-aikacen. Dangane da hanyoyin rufewa daban-daban, galibi ana raba bearings masu sassauƙa zuwa: hatimin roba-RS, hatimin ƙarfe-ZZ, saman lebur, ƙarfe katin-K, jan ƙarfe katin-M, da sauransu.

Bearings na ƙwallon sirarasuna da tsari mai sauƙi kuma suna da sauƙin amfani. Ana amfani da shi galibi don ɗaukar nauyin radial, amma lokacin da aka ƙara yawan radial clearance na bearing, yana da takamaiman aikin bearings na lamba mai kusurwa, kuma yana iya jure wa haɗin nauyin radial da axial. Lokacin da saurin juyawa ya yi yawa kuma bai dace da amfani da bearings na put ball ba, ana iya amfani da shi don ɗaukar nauyin axial tsarkakakku. Idan aka kwatanta da sauran nau'ikan bearings masu girma ɗaya, wannan nau'in bearing yana da ƙaramin ma'aunin gogayya da iyaka mai girma. Duk da haka, ba ya jure wa tasiri kuma bai dace da ɗaukar nauyi mai nauyi ba. Bearings na sashi mai sirara daidai wani nau'in bearing ne mai faɗi da kauri na musamman na giciye; Girman giciye iri ɗaya na iya daidaita diamita daban-daban na ciki na bearings; Idan aka kwatanta da bearings na yau da kullun, faɗi da kauri suna ƙaruwa daidai gwargwado tare da ƙaruwar diamita na ciki na bearing, yayin da bearings na sashi mai sirara daidai suke ƙara diamita na ciki kuma suna kiyaye girman giciye ba tare da canzawa ba.

 

Haɗakar girman sassa tara (daga 3/16" zuwa 1") da girman rami (daga 1" zuwa 40") na siraran sassan ɗaukar kaya zai haifar da bearings masu "sirara" da yawa tare da ƙananan sassa da manyan ramuka. Kayan ɗaukar kaya masu siraran sassan ƙarfe 52100 chrome da bakin ƙarfe 440C suma za a iya shafa su da siraran chrome. Ana iya sanya samfura da yawa tare da hatimi ko murfin ƙura. Akwai nau'ikan bearings masu siraran sassan guda uku daban-daban: bearings masu zurfin rami, bearings masu kusurwa, da bearings masu kusurwa huɗu. Idan aka kwatanta da bearings na yau da kullun, bearings masu sassa na iya inganta tsarin yadda ya kamata kuma rage jimillar farashi.
