- girman girma (kamar 30310):
Injinan gini (ƙafafun hanya na haƙa rami), babban shaft na na'urar niƙa ma'adinai, bambancin manyan motoci .
3. Bearings masu siffar silinda (jerin NN/NU)
- NN3020K (ginshi biyu):
Injin juyawa, injin juyawa mai sauri, injin juyawa mai daidaici, da kuma wuyan injin juyawa mai daidaici .
- Jerin YANZU:
Babban tallafin stator na mota, akwatin axle na jigilar jirgin ƙasa .
Manyan ƙa'idojin rarraba masana'antu:
1. Masana'antar kera motoci (kashi 43%)
Bearings na cibiyar (bearings masu tauri), bearings na janareta (bearings na ƙwallon zurfi), bearings na gearbox (bearings na ƙwallon hulɗa na kusurwa)
2. Makamashi da masana'antu masu nauyi
Babban shaft na injin turbin iska (bearings na nadi masu daidaita kansu), na'urar wutar lantarki ta zafi (bearings nadi mai silinda)
3. Kayan aiki masu inganci
Babban shaft na injin jirgin sama (bearings na ƙwallon yumbu), akwatin gear na jirgin ƙasa mai sauri (bearings masu daidaiton gudu).
Shawarar zaɓi: Ana iya amfani da bearings na irin wannan samfurin a yanayi daban-daban saboda daidaiton ma'aunin su (P5/P4). Misali, sandunan kayan aikin injin suna buƙatar daidaiton bearings na matakin P4 ko sama da haka . Bearings na wutar iska suna buƙatar ƙira ta musamman ta hana lalata da tsawon lokacin sabis . Don takamaiman sigogin samfuri, da fatan za a duba littafin fasaha na masana'anta.
Babban buƙatun aikin ɗaukar kaya sun bambanta sosai a cikin masana'antu daban-daban, galibi suna mai da hankali kan girma kamar daidaito, saurin juyawa, ƙarfin kaya, da daidaitawar muhalli.
Masana'antar kera motoci
1. Sabbin bearings na injin sarrafa makamashi: Ana buƙatar su sami matsakaicin gudu (ƙimar dm•n ≥ 70,000 mm·r/min), juriya mai zafi (> 150℃), da juriya mai ƙarfi na girgiza mai yawa. Kayan suna buƙatar samun kwanciyar hankali mai yawa, kuma tsarin shafawa yana buƙatar daidaitawa da yanayin aiki mai rikitarwa na injin .
1. Bearings na gargajiya na injin: Bearings na tensioner da idler pulley suna buƙatar samun ƙarfi mai yawa da ƙarancin hayaniya don biyan buƙatun watsawa masu inganci a ƙarƙashin yanayin kiyaye makamashin injin .
- Bearing na Hub: Bearing masu taurare suna buƙatar jure wa nauyin tasirin hanya biyu yayin da suke biyan buƙatun ƙira mai sauƙi da tsawon rai (kamar sama da kilomita miliyan 1).
Jirgin Sama
1. Iyakar daidaito: Juriyar bearings na injin aero yana buƙatar zama ≤0.005 millimeters (microns 5), kuma samfuran soja ma suna buƙatar daidaiton microns 0.1 .
- Juriyar muhalli mai tsanani:
- Bearings na sarari suna buƙatar su kasance masu juriya ga yanayin zafi mai yawa da ƙasa (-180℃ zuwa 300℃), radiation kuma suna da ƙarancin canjin iskar gas.
- Magance matsalar man shafawa ta injin ta hanyar amfani da kayan yumbu ko man shafawa na perfluoropolyether (PFPE).
- Aminci: Yiwuwar gazawa 20,000 juyin juya hali a minti daya).
Makamashi da Masana'antu Masu Girma
1. Babban shaft na injin turbin iska:
Bearings masu daidaita kansu suna buƙatar jure wa canjin iska mai ƙarfi da lokutan juyawa, kuma ya kamata a tsara murfin hana lalata don yanayin fesa gishiri.
Tsawon lokacin ƙira > shekaru 20, zagayowar kulawa ≥ shekaru 5 .
2. Kayan aikin wutar lantarki/magudanar ruwa:
Bearings na silinda suna ɗauke da nauyin radial na ɗaruruwan tan kuma ana amfani da su tare da tsarin sanyaya waje don sarrafa hauhawar zafin jiki.
Ana zaɓar nau'ikan ƙarfe na musamman (kamar ƙarfe M50) don yankunan da ke da yanayin zafi mai yawa .
