Njengeshishini lokuvelisa eligxile ekuveliseniiibheringi zebhloko yomqamelo, sisoloko sijonga umgangatho wemveliso njengomthombo wobomi benkampani yethu. Kutshanje, inkampani yethu ibhengeze ngokusesikweni ukugqitywa kophuculo olupheleleyo lwenkqubo yokuhlola, iseka indlela yokuhlola "epheleleyo, enemilinganiselo emininzi, elandelekayo" ukusuka ekungeneni kwezinto eziluhlaza ukuya ekuphumeni kwemveliso egqityiweyo. Eli phulo lijolise ekunikezeni iimveliso zokuthwala ezikumgangatho ophezulu, ezinokuthenjwa nezihlala ixesha elide kubathengi behlabathi ngemigangatho yokuhlolwa engqongqo kunye neenkqubo zokuhlola ezipheleleyo.
Iibheringi zepillow block zisetyenziswa kakhulu kumatshini wezolimo, izixhobo zokuhambisa, oomatshini bemigodi, izixhobo zokungenisa umoya, njl. Ukusebenza kwazo kuchaphazela ngokuthe ngqo uzinzo kunye nobomi bezixhobo. Ukuze kuhlangatyezwane neemfuno ezingqongqo zeemeko zokusebenza ezahlukeneyo, inkampani yethu ilandela ngokungqongqo imigangatho yoshishino efana ne-GB/T 27555-2011 “Rolling Bearings – Bearing Caps with External Spherical Surfaces” kunye ne-JB/T 8875-2001, kwaye isebenzisa ulawulo lomgangatho olupheleleyo kwiseti nganye yeebheringi. Umxholo ophambili wolu phuculo lwenkqubo yokuhlola ngolu hlobo lulandelayo:
1. Ukuhlolwa kwezinto eziluhlaza – Ukulawula umgangatho ovela kumthombo
Izinto ezisemgangathweni ophezulu zisisiseko seebheringi ezikumgangatho ophezulu. Siqhuba uhlolo olungqongqo lwezinto kwibhetshi nganye yentsimbi engenayo kunye nee-castings, sisebenzisa ii-spectrometers ze-Thermo Scientific direct reading ukuze sihlalutye ngokuchanekileyo ukwakheka kweekhemikhali zee-bearing shells kunye nezinto eziqengqelekayo (ngokuchaneka kohlalutyo lwezinto ukuya kuthi ga kwi-0.001%). Siqinisekisa ukuba ukwakheka kwezinto kuyahlangabezana neemfuno ezisemgangathweni. Kwangaxeshanye, ngovavanyo lobunzima, silawula i-gradient yobunzima bomphezulu we-Rockwell (HRC 58-62) kunye nobunzima be-core (HRC 25-35) ukuqinisekisa ukumelana nokuguguleka okugqwesileyo kunye nokuqina. Ii-casting caps zihlolwa nganye nganye ukuze kubonwe iziphene zomphezulu ezifana nemifantu, ii-pores, kunye ne-shrinkage cavities.
2. Ubungakanani kunye nokuchaneka kwemilo yezixhobo - Ukuphishekela ukugqwesa
Ukuchaneka kwee-bearing caps ezinee-spherical surfaces zangaphandle kumisela ngokuthe ngqo umgangatho wazo wokuhlanganisa kunye nokusebenza. Ngexesha lesigaba sokucubungula iinxalenye, sisebenzisa izixhobo zokulinganisa ezintathu zeMitutoyo (ezichanekileyo ze-1.5 μm) ukuqokelela nokuvavanya idatha enemilinganiselo emininzi yobubanzi bangaphakathi, ububanzi bangaphandle, ububanzi, kunye nokunyamezelana kwemingxunya yesihlalo see-bearings. Kwangaxeshanye, sisebenzisa ii-roundness gauges kunye nee-profile meters ukuhlalutya ngokuchanekileyo i-roundness, cylindricality, kunye neempazamo ze-spherical shape zeeringi zangaphakathi nezangaphandle zee-bearings. Ukuphambuka komda kwemilinganiselo ephambili efana nokuphakama kwembindi yomphezulu we-spherical kulawulwa ngokungqongqo ngaphakathi koluhlu oluqhelekileyo. Kwi-spherical roughness, sisebenzisa ii-Keyence three-dimensional surface profilometers ukuqinisekisa ukuba i-roughness Ra ≤ 0.2 μm.
3. Ukuhlolwa kokuchaneka kwemitha kunye nokuchaneka kokujikeleza - Ukuqinisekisa ukusebenza kakuhle
Ukucaciswa kwemitha kunye nokuchaneka kokujikeleza zezona zibonakaliso ziphambili zokulinganisa ukusebenza kweebheringi. Sisebenzisa indlela yokunxibelelana enamachaphaza amathathu ukulinganisa ukucaciswa kwemitha yangaphakathi yeebheringi ukuqinisekisa ukuba ilawulwa ngokuzinzileyo ngaphakathi koluhlu oluqhelekileyo lokunyamezela oluyi-0.05-0.15 mm, ngokuhambelana neemfuno ze-ISO5753:2009. Ukuvavanya ukuchaneka kokujikeleza, sisebenzisa ii-laser interferometers ukufumanisa ukujikeleziswa kwemitha ye-axial (≤ 0.03 mm) kunye nokujikeleziswa kwemitha ye-radial (≤ 0.05 mm), ukuqinisekisa ukuguda kunye nokuchaneka kweebheringi ngexesha lokusebenza ngesantya esiphezulu.
4. Ukuguquguquka kokujikeleza kunye nokuhlolwa kokusebenza kokutywina - Ukulinganisa iimeko zokusebenza zokwenyani
Ukuguquguquka kokujikeleza kuchaphazela ngokuthe ngqo ukusebenza kakuhle kwezixhobo. Emva kokuba iseti nganye yeebheringi idityanisiwe, ivavanywa ngesandla kwaye ifunyanwe ngobuninzi nge-torque tester ukujonga ukuba ukujikeleza kuhamba kakuhle na, akukho kunamathela okanye izandi ezingaqhelekanga. Ukuze sisebenze ngokutywina, sisebenzisa ibhentshi yovavanyo lokutywina ukuqinisekisa inqanaba lokukhusela le-IP65 yeebheringi, ukulinganisa uthuli kunye neendawo zokufuma kwamanzi ukuze kuqhubeke ukusebenza imizuzu engama-30, kunye nokuvavanya ukumelana kothuli kunye namanzi kweeringi zokutywina kunye negrisi yokuthambisa ukuqinisekisa ukuthembeka kweebheringi kwiimeko zokusebenza ezinzima.
5. Uhlalutyo lokungcangcazela nengxolo – Uvavanyo olupheleleyo lokusebenza okuguquguqukayo
Amanqanaba okungcangcazela kunye nengxolo zizinto ezibalulekileyo zokuvavanya imeko yempilo yeebheringi. Sixhobise inkqubo yohlalutyo lokungcangcazela yeBruel & Kjaer (enoluhlu lwe-frequency lwe-5Hz - 20kHz) kunye ne-Schaeffler FAG bearing analyzer ukuqokelela kunye nokuhlalutya ii-vibration spectra zeseti nganye yeebheringi ezigqityiweyo. Ngokuthelekisa imida ye-spectral yemigangatho yamazwe ngamazwe efana ne-ISO 15242, sinokuchonga ngokuchanekileyo iziphene zangaphakathi ezifana nomonakalo wendlela yokukhwela ihashe, ukuguguleka okungalinganiyo kweebhola, okanye iimpazamo zekheyiji. Iibheringi ezisemgangathweni ophezulu eziqhelekileyo zigcina amanqanaba aphantsi okungcangcazela kunye nengxolo ngexesha lokusebenza.
Isithandathu. Uvavanyo loMthwalo oDynamic kunye nokuQiniseka koKuhlala ixesha elide – Ukuqinisekiswa koMthamo woKuthwala
Ukuqinisekisa amandla okuthwala kunye nobomi benkonzo yeebheringi phantsi kweemeko zokusebenza zangempela, sisebenzise umatshini wokuvavanya ukudinwa kwe-Instron hydraulic servo (onomthwalo ophezulu we-250kN) ukwenza uvavanyo lomthwalo oguqukayo. Siqinisekisile ukusebenza kweebheringi phantsi kwemithwalo ye-axial ye-≥ 1.5 ngokuphindwe ixabiso elilinganisiweyo kwaye saqinisekisa ukuba ukunyuka kobushushu ngexesha lokusebenza okuqhubekayo iiyure ezingama-200 akudluli kwi-45℃. Kwangaxeshanye, sibale ubomi obulinganisiweyo ngokuhambelana nomgangatho we-ISO 281:2007 ukuqinisekisa ukuba ubomi be-L10 buyi-≥ iiyure ezili-10,000.
VII. Ukuhlolwa kweNkangeleko kunye nokuhlolwa kokugqibela kweFektri - Indawo yokugqibela yokujonga umgangatho
Ngaphambi kokuba kugqitywe ukupakisha, iseti nganye yeebheringi kufuneka ihlolwe ngokubonakalayo kusetyenziswa zombini ukujonga okubonakalayo kunye neemakroskopu ezibonakalayo ukujonga naziphi na iziphene ezifana nokuqhekeka, umhlwa, imikrwelo, okanye ukurhawuzelelwa kumphezulu. Umgangatho wepeyinti yendlu yeebheringi kunye nonyango lomphezulu kuyahlolwa ukuqinisekisa ukuba iimpawu kunye nolwazi lokupakisha lucacile kwaye luphelele. Ixabiso eliseleyo lemagnethi liyavavanywa ukuqinisekisa ukuthotyelwa kwemigaqo ye-JB/T 6641. Yonke idatha yovavanyo irekhodwa ngexesha langempela kwaye ingeniswa kwinkqubo ukuze kufezekiswe "ukulandelelana kwekhowudi enye" ​​- iseti nganye yeebheringi eziveliswayo inokulandelwa emva kwibhetshi yezinto eziluhlaza, inkqubo yokucubungula, kunye neerekhodi zovavanyo.
Ukuzibophelela kwabathengi
Ukuphuculwa okubanzi kwenkqubo yovavanyo kukuzibophelela kwethu ngokuqinileyo kwifilosofi "yomgangatho kuqala". Ukususela ekungeneni kwezinto eziluhlaza ukuya ekugqityweni kwemveliso egqityiweyo, yonke inkqubo, yonke iparameter, kunye novavanyo ngalunye zisekelwe kwimigangatho yamazwe ngamazwe kunye neemfuno zabathengi. Siyaqonda ukuba oko sikuzisa kubathengi akusiyo nje iseti yeebheringi, kodwa kukuzibophelela okunzulu ekusebenzeni okuzinzileyo kwezixhobo.
Kwixesha elizayo, siza kuqhubeka nokuphucula inkqubo yovavanyo size sazise izixhobo zovavanyo eziphambili ukubonelela abathengi behlabathi ngeenkonzo ezibalaseleyo zomgangatho wemveliso. Wamkelekile abathengi abatsha nabadala ukuba batyelele umzi-mveliso wethu ukuze bafumane ulwalathiso kwaye babone ukufuna kwethu umgangatho kunye!
