Radial spherical plain bearings

Radial spherical plain bearings sune mahimman abubuwa a cikin aikace-aikacen masana'antu iri-iri, suna ba da tallafi na pivot don jujjuyawa da sauran sassa masu motsi. An ƙera shi don ɗaukar nauyin radial, axial ko haɗuwa, waɗannan bearings ana amfani dasu sosai a cikin injina, tsarin kera motoci da kayan aikin sararin samaniya. Fahimtar rarrabuwa na radial bearings yana da mahimmanci don zaɓar nau'in daidai don takamaiman aikace-aikacen da tabbatar da ingantaccen aiki da rayuwar sabis.

Rarraba na radial mai siffar zobe bearings

Za'a iya rarraba filaye masu siffar zobe na radial bisa la'akari da mahimman abubuwa da yawa, gami da ƙirarsu, kayan aiki da halayen aikinsu. Ta hanyar fahimtar waɗannan rabe-raben, injiniyoyi da ƙwararrun kulawa za su iya yanke shawara mai fa'ida lokacin zabar bearings don aikace-aikace daban-daban.

1. Tsarin ƙira

Radial fili bearings suna samuwa a cikin nau'i-nau'i iri-iri don saduwa da kaya daban-daban da bukatun motsi. Mafi yawan ƙira sun haɗa da:

- Karfe akan Karfe: Wadannan bearings sun ƙunshi zobe na ciki tare da madaidaicin saman waje da zobe na waje tare da madaidaicin saman ciki, duka biyun an yi su da ƙarfe mai tauri. Sun dace da aikace-aikace masu nauyi kuma suna iya jure nauyin radial mai nauyi da girgiza.

- Karfe Bronze: A cikin wannan zane, zobe na ciki an yi shi da ƙarfe mai tauri, yayin da zoben na waje an yi shi da tagulla. Wannan zane yana ba da juriya mai kyau kuma ya dace da aikace-aikace tare da matsakaicin nauyi da motsi na oscillatory.

- PTFE (polytetrafluoroethylene): Abubuwan da aka haɗa tare da PTFE composite ko PTFE masana'anta rufi suna ba da ƙarancin gogayya, kayan shafa mai kai da juriya ga lalata da lalacewa. Waɗannan bearings sun dace don aikace-aikacen da ke buƙatar aiki mara izini da tsawaita rayuwar sabis.

- Bronze: Tagulla masu layi na tagulla suna da juriya mai kyau kuma suna iya jure matsakaicin nauyi da motsin oscillatory. Sun dace da aikace-aikacen da ke buƙatar daidaitaccen ƙarfin nauyi da juriya.

3. Rarraba ayyuka

Hakanan ana rarraba nau'ikan filaye masu siffar zobe na radial bisa ga halayen aikinsu, gami da ƙarfin ɗaukar kaya, iyawar rashin daidaituwa da kewayon zafin aiki. Waɗannan rabe-raben ayyukan suna taimakawa wajen zaɓar mafi dacewa da tasiri don takamaiman aikace-aikacen:

- Ƙarfin ɗaukar nauyi: Matsakaicin ƙimar radial da nauyin ɗaukar nauyi na ɗaukar nauyi yana ƙayyade dacewarsu don aikace-aikace daban-daban. Ƙaƙƙarfan aiki mai ƙarfi na iya jure nauyi mai nauyi da nauyin girgiza ba tare da gazawar da wuri ba.

- Ƙarfin Kuskure: Wasu bearings an ƙera su don ɗaukar rashin daidaituwa tsakanin shaft da gidaje, ba da damar aiki mai laushi ko da a aikace-aikace tare da karkatar da shaft ko rashin daidaituwa.

- Kewayon Zazzabi Mai Aiki: An ƙididdige masu ɗaukar nauyi don matsakaicin kuma mafi ƙarancin yanayin aiki, yana tabbatar da ingantaccen aiki a ƙarƙashin matsanancin yanayin zafi.

Aikace-aikace na radial bearings
