Bearings na jirgin ƙasa - halaye da aikace-aikacen bearings na gearbox

Tare da ci gaban al'umma, masana'antar kera injunan layin dogo tana ci gaba da ingantawa, idan aka kwatanta da fasahar kera bearing na layin dogo kuma tana ci gaba da ingantawa, wanda babban aikin bearing na birgima a cikin akwatin gear shine ya sami damar isar da karfin fitarwa cikin kwanciyar hankali lokacin da locomotive ke gudana a babban gudu, wanda ke nufin dole ne su ɗauki nauyin tasirin da za a iya canzawa a cikin yanayin rikitarwa. Manyan nau'ikan bearing sune bearing na birgima mai taurare, bearing na lamba huɗu da bearing na birgima mai silinda. Shirye-shiryen bearing sun bambanta dangane da ƙira da yanayin aiki na akwatin gear.

 

Bearings na gearbox na axle

Babban aikin aikace-aikacen bearings don gearboxes shine:

Babban gudu; Babban ɗaukar nauyi; Juriyar girgiza da girgiza; Juriyar zafin jiki mai yawa.

Zabin bearing ana ƙaddara shi gwargwadon girman yankin da ya dace na akwatin gear, la'akari da abubuwan da ke sama, kuma gabaɗaya yana buƙatar tsawon rai na sama da kilomita miliyan 2.

 

Aikace-aikacen gearbox na axle

1. Bearings masu taurare

Ana iya raba bearings ɗin naɗa mai tauri, kuma ana iya haɗa su daban-daban a cikin keji naɗa mai zobe da zobe na waje. Daidaitawar layi tsakanin abubuwan birgima da hanyar tsere yana hana matsin lamba a gefen. Bearings ɗin naɗa mai tauri na iya jure wa manyan nauyin radial da axial. Domin waɗannan bearings za su iya jure wa ƙarfin axial kawai a gefe ɗaya, suna buƙatar a yi amfani da su wajen haɗa su. Ana amfani da wannan nau'in bearings a cikin akwatunan gearbox da akwatunan axle.

 

2. Huɗu mai lamba mai lamba

Bearings na ƙwallon hulɗa mai maki huɗu sune bearings na ƙwallon hulɗa mai kusurwa. Yana iya jure nauyin axial a duka kwatance kuma yawanci ana haɗa shi da bearings na silinda don jure ƙarfin radial, tare da dacewa da radial clearance. Tsarin raba zoben ciki yana ba shi damar haɗa ƙarin ƙwallan ƙarfe. Ana amfani da waɗannan bearings a cikin akwatunan gearbox.

 

3.Bearings na silinda

Ana amfani da bearings na silinda mai layi ɗaya a cikin bearings na jirgin ƙasa fiye da sauran bearings saboda ana iya raba zoben ciki daga haɗuwar da aka haɗa da zoben waje, birgima da keji, wanda ke da matuƙar amfani ga shigarwa, wargazawa, kulawa da duba bearings. Bearings na silinda suna iya jure wa manyan ƙarfin radial, kuma haɗin layi da aka gyara tsakanin abubuwan birgima da hanyar tsere yana kawar da matsin lamba a gefen, yana ƙara amincin aikace-aikacen bearings. Haɗin bearings na silinda na NJ da NUP na iya jure wa ƙarfin axial akai-akai. Ana amfani da waɗannan bearings a cikin injinan jan hankali, gearboxes, da tuƙin shaft mai rami.

 

4. Bearings masu rufi

A ƙarƙashin wasu yanayi mara kyau ko na musamman, bearing na shaft da bearing na mota na iya lalacewa saboda ƙarin ƙarfin lantarki. Duk da cewa tsarin kera motar ya yi kyau, ba zai yiwu a guji cikakken bambancin da ke tsakanin rotor da stator ba saboda rashin daidaituwar lantarki, don haka wutar lantarki ta ratsa bearing kuma ta samar da da'ira mai rufewa. Domin gujewa yanayin da ke sama, a shafa wani shafi na yumbu mai oxide a saman zoben waje na bearing don toshe ƙarfin lantarki ba ƙasa da 1000V ba, kuma a kare bearing daga gazawar bearing saboda zaizayar lantarki da ƙarin ƙarfin lantarki ya haifar.
