Njengebhizinisi lokukhiqiza eligxile ekukhiqizeniamabheringi ebhlogo lomcamelo, sihlala sibheka ikhwalithi yomkhiqizo njengomthombo wempilo wenkampani yethu. Muva nje, inkampani yethu imemezele ngokusemthethweni ukuqedwa kokuthuthukiswa okuphelele kohlelo lokuhlola, isungula indlela yokuhlola "egcwele inqubo, enezinhlangothi eziningi, elandelekayo" kusukela ekungeneni kwezinto zokusetshenziswa kuya ekuphumeni komkhiqizo oqediwe. Lesi sinyathelo sihlose ukuletha imikhiqizo yokuthwala esezingeni eliphezulu, ethembekile futhi eqinile kumakhasimende omhlaba wonke ngezindinganiso zokuhlola eziqinile kanye nezinqubo zokuhlola eziphelele.
Ama-pillow block bearings asetshenziswa kabanzi emishinini yezolimo, imishini yokuthutha, imishini yezimayini, imishini yokungenisa umoya, njll. Ukusebenza kwawo kuthinta ngqo ukuzinza kanye nesikhathi sokuphila kwemishini. Ukuze kuhlangatshezwane nezidingo eziqinile zezimo zokusebenza ezahlukene, inkampani yethu ilandela ngokuqinile amazinga embonini njenge-GB/T 27555-2011 “Rolling Bearings – Bearing Caps with External Spherical Surfaces” kanye ne-JB/T 8875-2001, futhi isebenzisa ukulawulwa kwekhwalithi okugcwele kwesethi ngayinye yama-bearings. Okuqukethwe okuyinhloko kwalokhu kuthuthukiswa kohlelo lokuhlola kungokulandelayo:
1. Ukuhlolwa kwezinto ezingavuthiwe - Ukulawula ikhwalithi evela emthonjeni
Izinto zokusetshenziswa ezisezingeni eliphezulu ziyisisekelo sama-bearings asezingeni eliphezulu. Senza ukuhlolwa okuqinile kwezinto ezibonakalayo kuqoqo ngalinye lensimbi engenayo kanye nama-castings, sisebenzisa ama-spectrometer okufunda ngqo e-Thermo Scientific ukuze sihlaziye ngokunembile ukwakheka kwamakhemikhali kwamagobolondo okuthwala kanye nezinto ezigoqekayo (ngokunemba kokuhlaziywa kwezinto kuze kufike ku-0.001%). Siqinisekisa ukuthi ukwakheka kwezinto kuhlangabezana nezidingo ezijwayelekile. Ngesikhathi esifanayo, ngokuhlolwa kokuqina, silawula i-gradient yokuqina kwe-surface Rockwell (HRC 58-62) kanye nokuqina kwe-core (HRC 25-35) ukuqinisekisa ukumelana nokuguguleka okuhle kakhulu. Ama-casting caps ahlolwa ngamunye ngamunye ukuze kutholakale amaphutha ebusweni njengemifantu, ama-pores, kanye nemigodi yokuncibilika.
2. Ukunemba kobukhulu kanye nesimo sezingxenye - Ukuphishekela ubuhle
Ukunemba kwama-bearing caps anezindawo zangaphandle eziyindilinga kunquma ngqo ikhwalithi yokuhlangana kwawo kanye nokusebenza kwawo. Ngesikhathi sesigaba sokucubungula izingxenye, sisebenzisa izinsimbi zokulinganisa ezintathu zeMitutoyo (ngokunemba okungu-1.5 μm) ukuqoqa nokuhlola idatha enezilinganiso eziningi zobubanzi bangaphakathi, ububanzi bangaphandle, ububanzi, kanye nokubekezelelana kwembobo yesihlalo yama-bearing. Ngesikhathi esifanayo, sisebenzisa ama-gauge obuyindilinga kanye namamitha ephrofayili ukuze sihlaziye ngokunembile amaphutha obuyindilinga, obuyindilinga, kanye nesimo esiyindilinga samasongo angaphakathi nangaphandle ama-bearing. Ukuphambuka komkhawulo wobukhulu obubalulekile njengokuphakama okuphakathi kwendawo eyindilinga kulawulwa ngokuqinile ngaphakathi kobubanzi obujwayelekile. Ukuze kube nobulukhuni bobuso, sisebenzisa ama-profilometer obuphezulu obuyizilinganiso ezintathu zeKeyence ukuqinisekisa ukuthi ubulukhuni beRa ≤ 0.2 μm.
3. Ukuhlolwa kokunemba kokujikeleza kwe-radial kanye nokuhlolwa kokunemba kokujikeleza - Ukuqinisekisa ukusebenza kahle
Ukucaciswa kwemisebe kanye nokunemba kokujikeleza kuyizinkomba eziyinhloko zokulinganisa ukusebenza kwama-bearings. Sisebenzisa indlela yokuxhumana enamaphuzu amathathu ukukala ukucaciswa kwemisebe yangaphakathi yama-bearings ukuqinisekisa ukuthi ilawulwa ngokuzinzile ngaphakathi kobubanzi obujwayelekile bokubekezelela obungu-0.05-0.15 mm, ngokuhambisana nezimfuneko ze-ISO5753:2009. Ekuhlolweni kokunemba kokujikeleza, sisebenzisa ama-interferometer e-laser ukuthola ukucaciswa kwemisebe ye-axial (≤ 0.03 mm) kanye nokucaciswa kwemisebe ye-radial (≤ 0.05 mm), ukuqinisekisa ukushelela nokunemba kwama-bearings ngesikhathi sokusebenza ngesivinini esikhulu.
4. Ukuguquguquka kokujikeleza kanye nokuhlolwa kokusebenza kokuvala - Ukulingisa izimo zokusebenza zangempela
Ukuguquguquka kokujikeleza kuthinta ngqo ukusebenza kahle kwemishini. Ngemva kokuba isethi ngayinye yama-bearings isihlanganisiwe, ihlolwa ngokujikeleza ngesandla kanye nokutholwa kwenani nge-torque tester ukuhlola ukuthi ukujikeleza kubushelelezi yini, ngaphandle kokunamathela noma imisindo engavamile. Ukuze sisebenze kahle ekuvaleni, sisebenzisa ibhentshi lokuhlola ukuvala ukuqinisekisa izinga lokuvikela le-IP65 lama-bearings, silingisa izindawo zothuli kanye nenkungu yamanzi ukuze kusebenze ngokuqhubekayo imizuzu engama-30, kanye nokuhlola ukumelana kothuli namanzi kwama-sealing rings kanye ne-lubricating grease ukuqinisekisa ukuthembeka kwama-bearings ezimweni zokusebenza ezinzima.
5. Ukuhlaziywa kokudlidliza nomsindo – Ukuhlolwa okuphelele kokusebenza okuguquguqukayo
Amazinga okudlidliza nomsindo ayindlela ebalulekile yokuhlola isimo sempilo yama-bearings. Sihlomise uhlelo lokuhlaziya ukudlidliza lwe-Bruel & Kjaer (olunebanga lokuvama elingu-5Hz – 20kHz) kanye ne-Schaeffler FAG bearing analyzer ukuze siqoqe futhi sihlaziye ama-vibration spectra esethi ngayinye yama-bearings aqediwe. Ngokuqhathanisa imikhawulo yama-spectral yezindinganiso zomhlaba wonke njenge-ISO 15242, singabona ngokunembile amaphutha angaphakathi njengomonakalo we-raceway, ukuguguleka okungalingani kwamabhola, noma amaphutha ekheji. Ama-bearings ajwayelekile asezingeni eliphezulu agcina amazinga aphansi okudlidliza nomsindo ngesikhathi sokusebenza.
Isithupha. Ukuhlolwa Komthwalo Oguquguqukayo Nokuqina - Ukuqinisekiswa Komthamo Wokuthwala
Ukuze siqinisekise amandla okuthwala kanye nokuphila kwenkonzo kwama-bearings ngaphansi kwezimo zokusebenza zangempela, sisebenzise umshini wokuhlola ukukhathala we-servo we-Instron hydraulic (onomthwalo omkhulu ongu-250kN) ukwenza izivivinyo zomthwalo oguquguqukayo. Siqinisekisile ukusebenza kwama-bearings ngaphansi kwemithwalo ye-axial ephindwe izikhathi ezingu-≥ 1.5 kunenani elilinganiselwe futhi saqinisekisa ukuthi ukwenyuka kwezinga lokushisa ngesikhathi sokusebenza okuqhubekayo amahora angu-200 akudluli ku-45℃. Ngesikhathi esifanayo, sibale impilo elinganiselwe ngokuhambisana ne-ISO 281:2007 standard ukuqinisekisa ukuthi impilo ye-L10 ingu-≥ amahora angu-10,000.
VII. Ukuhlolwa Kokubonakala kanye Nokuhlolwa Kokugcina Kwefektri – Indawo Yokuhlola Ikhwalithi Yokugcina
Ngaphambi kokuba kuqedwe ukupakishwa, isethi ngayinye yama-bearings kumele ihlolwe ngokubonakalayo kusetshenziswa kokubili ukubuka okubonakalayo kanye nama-microscope optical ukuhlola noma yiziphi iziphambeko ezifana nokuqhekeka, ukugqwala, imihuzuko, noma ukuklwebheka ebusweni. Ikhwalithi yopende wendlu yama-bearings kanye nokwelashwa kwendawo nakho kuyahlolwa ukuqinisekisa ukuthi izimpawu kanye nolwazi lokupakisha lucacile futhi luphelele. Inani elisele lamagnetic liyahlolwa ukuqinisekisa ukuhambisana nemithethonqubo ye-JB/T 6641. Yonke idatha yokuhlola iqoshwa ngesikhathi sangempela futhi ifakwa ohlelweni ukuze kufezwe "ukulandelela ikhodi eyodwa" - isethi ngayinye yama-bearings akhiqizwayo ingalandelelwa emuva ku-batch yezinto zokusetshenziswa, inqubo yokucubungula, kanye namarekhodi okuhlola.
Ukuzibophezela Kwamakhasimende
Ukuthuthukiswa okuphelele kohlelo lokuhlola ukuzibophezela kwethu okuqinile kwifilosofi ethi “ikhwalithi kuqala”. Kusukela ekungeneni kwezinto zokusetshenziswa kuya ekuqedeni umkhiqizo oqediwe, yonke inqubo, yonke ipharamitha, kanye nokuhlolwa ngakunye kusekelwe ezindinganisweni zomhlaba wonke kanye nezidingo zamakhasimende. Siyaqonda ukuthi lokho esikunikeza amakhasimende akuyona nje isethi yeziqondiso, kodwa ukuzibophezela okuqinile ekusebenzeni okuzinzile kwemishini.
Esikhathini esizayo, sizoqhubeka nokuthuthukisa inqubo yokuhlola futhi sethule imishini yokuhlola ethuthukisiwe ukuze sinikeze amakhasimende omhlaba wonke izinsizakalo zekhwalithi yomkhiqizo ezivelele kakhulu. Siyakwamukela amakhasimende amasha namadala ukuthi avakashele ifektri yethu ukuze athole isiqondiso futhi sibone ukuphishekela kwethu ikhwalithi ndawonye!
