Mabheyaringi ekupisa kwakanyanya

Chii chinonzi High Temperature Bearing?

Zvinonzi fani yekupisa kwepamusoro zvinoreva kuti tembiricha yekushanda yakakwira kupfuura tembiricha yefani yemazuva ese, uye fanicha inoshandiswa patembiricha yekushanda yakajairika inopfuura 150 degrees.° inonzi bearing inodziya zvakanyanya.

 

Hunhu hwemabheyaringi ekupisa kwakanyanya:

 

1. Kuzora mafuta kwehupenyu hwese, hapana mafuta anowedzerwa panguva yekushandisa.

 

2. Inodhura zvishoma, mhando yacho yakakwira kakawanda kupfuura yemabheyaringi akajairwa.

 

3. Yaita kuti vatengi vedu vavimbe nayo nekushanda kwenguva refu.

 

4. Mabheringi anodziya zvakanyanya anoshandiswa zvakanyanya mukugadzira simbi, maovheni, magirazi, maovheni ekuputika, midziyo yekupenda nemimwe michina iri kushandiswa pakupisa kwakanyanya.

 

Mabheringi anodziya zvakanyanya anonyanya kushandiswa muinjini dzendege, maturbine egasi, masisitimu eatoriki enyukireya, madhisiki eX-ray tube tungsten, mota dzinomhanya zvakanyanya, maroketi, uye zvitundumuseremusere.

 

Kuiswa kwemabheringi anodziya zvakanyanya

Pamusoro pezvo, kana kumanikidzwa kukaiswa kune rimwe divi rerin'i (senge rin'i rekunze), uye rimwe divi rerin'i (senge rin'i remukati) rikamanikidzwa mukati maro kuburikidza nechinhu chinotenderedza, izvi zvinowanzo kukonzera kuvharika kana kukwenya pamusoro perin'i, uye hazvifanirwe kushandiswa, kunyanya kana bearing isingaparadzaniswe yakaiswa pashaft nebearing housing panguva imwe chete.

 

Mukati mekupisa nekuisa bearing, zvakakosha kunzwisisa huwandu hwekupisa hwebearing yepamusoro pasi pemabearing akasiyana-siyana ekupisa kwepamusoro.

 

Kukwana kwemabheyaringi anodziya zvakanyanya

1. Kupindira

 

Mhete yemukati nemhete yekunze yechinhu chinotenderera zvakasungirirwa pabhokisi remubato kana remabheyaringi, uye kana zvaiswa, mhete nebhokisi remubato kana remabheyaringi hazvina mafambiro e radial, axial uye rotational relative movements, uye kufamba uku kunokonzera kukweshana, friction corrosion kana friction cracks pamusoro pemating, zvekuti zvinokanganisa bearing, shaft nebhokisi remabheyaringi, uye ipapo abrasion powder inosanganiswa mubearing, izvo zvinova chikonzero chekushanda zvisina kunaka, kupisa kusina kujairika kana kudedera.

 

Kana iri nzira yekubata zvinhu zvakagadzika, zvakanaka kusiya huwandu hwekupindira pamusoro peringi neshaft kana bearing housing, uye static fit ndiyo yakakodzera, kuitira kuti mutoro weringi ine madziro matete ugovaniswe zvakaenzana padenderedzwa pasina kukanganisa mutoro webearing.

 

Zvisinei, pamusoro pekusagadzikana kwekubatanidza nekuburitsa bearing, haigone kushandiswa mune zvese zviitiko kana bearing yakaparadzaniswa uye haigone kufambiswa neaxial kana bearing yakaparadzaniswa kana bearing ichishandiswa.

 

2. Sarudzo yezvakakodzera

 

Kusarudzwa kwemuchina wekunamira kunowanzoitwa zvichienderana nepfungwa dzinotevera:

 

(1) Zvichienderana negwara uye hunhu hwemutoro unoshanda pabearing uye kuti ndeipi divi remhete dzemukati nedzekunze dzinotenderera, mutoro unotakurwa nering yega yega unogona kukamurwa kuita mutoro unotenderera, mutoro usingachinji, kana mutoro usingachinji, mhete inotakura mutoro unotenderera uye mutoro usingachinji inofanira kutora static fit (kupindirana), mhete inotakura mutoro usingachinji inogona kutora transition fit kana dynamic fit (clearance fit), kana mutoro webearing uri mukuru kana uine vibration uye shock load, kupindira kunofanirwa kuwedzerwa, kana hollow shaft, thin-walled bearing box kana light alloy neplastic bearing box zvichishandiswa, Zvakakoshawo kuwedzera huwandu hwekupindira.

 

(2) Kana zvichidikanwa kuchengetedza kutenderera kwakanyatsojeka, mabheringi akanyatsojeka anofanira kushandiswa, uye kurongeka kwezvikamu zvemashaft nemabhokisi ekutakura kunofanirwa kuvandudzwa, kuitira kudzivirira kupindira kwakanyanya, kana kupindira kwacho kwakanyanya, kurongeka kwejometri yebhokisi rekutakura kana re axle kunogona kukanganisa kuenzana kweringi yekutakura, nokudaro zvichikanganisa kuenzana kwekutenderera kweringi, kana mhete dzemukati nedzekunze dzemabheringi asingaparadzanise (senge mabheringi ebhora akadzika) dzakanyatsokwana, saka kuiswa kwebheringi nekubviswa kwayo hazvina kunaka zvakanyanya, uye zvakanakisa kushandisa kupindirana kwakasimba kune rumwe rutivi rweringi rekunze.

 

3. Kushandira pamwe kunokurudzirwa

 

Nezve dhayamita yeshaft nehukuru hwebore hweshaft nebearing housing uko mabearing akaiswa, ISO283 (dimensional tolerances and fits) yakagamuchirwa mu metric series, saka fit tolerances dzakasarudzwa zvichienderana nedhayamita yeshaft nehukuru hwebore.
