Ayyukansu kai tsaye yana shafar kwanciyar hankali da tsawon rayuwar kayan aikin. Don biyan buƙatun yanayi daban-daban na aiki, kamfaninmu yana bin ƙa'idodin masana'antu kamar GB/T 27555-2011 "Bearings na Rolling - Belaging Caps with Outfold Spherical Surfaces" da JB/T 8875-2001, kuma yana aiwatar da cikakken tsarin kula da inganci ga kowane saitin bearings. Babban abin da ke cikin wannan haɓaka tsarin dubawa shine kamar haka:
1. Duba kayan ƙasa - Sarrafa inganci daga tushen
Kayan aiki masu inganci su ne ginshiƙin bearings masu inganci. Muna gudanar da bincike mai tsauri kan kowane rukuni na ƙarfe da simintin da ke shigowa, ta amfani da na'urorin auna karatu na Thermo Scientific direct reading spectrometers don yin nazarin sinadaran da ke cikin harsashin bearing da abubuwan birgima daidai (tare da daidaiton nazarin abubuwa har zuwa 0.001%). Muna tabbatar da cewa kayan sun cika buƙatun da aka saba. A lokaci guda, ta hanyar gwaje-gwajen tauri, muna sarrafa yanayin tauri na saman Rockwell (HRC 58-62) da kuma tauri na tsakiya (HRC 25-35) don tabbatar da kyakkyawan juriya da juriya. Ana duba murfin simintin ɗaya bayan ɗaya don gano lahani na saman kamar fashe-fashe, ramuka, da ramukan raguwa.
2. Girma da daidaiton siffar sassan - Neman ƙwarewa
Daidaiton murfin bearings tare da saman sphere na waje yana ƙayyade ingancin haɗuwarsu da aikin aiki kai tsaye. A lokacin aikin sarrafa kayan, muna amfani da kayan aikin aunawa masu daidaitawa uku na Mitutoyo (tare da daidaito na 1.5 μm) don tattarawa da gwada bayanai masu girma dabam-dabam don juriyar diamita na ciki, diamita na waje, faɗi, da ramin zama na bearings. A lokaci guda, muna amfani da ma'aunin zagaye da mitar bayanin martaba don yin nazarin daidai kurakuran zagaye, silinda, da siffar sphere na zoben ciki da na waje na bearings. Ana sarrafa bambance-bambancen iyaka na maɓallan girma kamar tsayin tsakiya na saman sphere a cikin kewayon da aka saba. Don tsananin saman, muna amfani da ma'aunin saman Keyence mai girma uku don tabbatar da cewa tsananin Ra ≤ 0.2 μm.
3. Duba daidaiton juyawa da kuma tabbatar da aiki mai kyau - Tabbatar da aiki mai kyau
Daidaiton juyawa da kuma daidaiton juyawa sune manyan alamu don auna aikin bearings. Muna amfani da hanyar hulɗa mai maki uku don auna daidaiton radial na ciki na bearings don tabbatar da cewa an sarrafa shi daidai a cikin kewayon haƙuri na yau da kullun na 0.05-0.15 mm, daidai da buƙatun ISO5753: 2009. Don gwajin daidaiton juyawa, muna amfani da na'urorin laser don gano saurin gudu na axial (≤ 0.03 mm) da saurin gudu na radial (≤ 0.05 mm), tare da tabbatar da santsi da daidaiton bearings yayin aiki mai sauri.
4. Sassauƙan juyawa da duba aikin rufewa - Kwaikwayon yanayin aiki na gaske
Sassaucin juyawa yana shafar ingancin aiki na kayan aiki kai tsaye. Bayan an haɗa kowace saitin bearings, ana gwada juyawa da hannu da kuma gano adadi tare da na'urar gwada karfin juyi don duba ko juyawar tana da santsi, ba tare da sauti mai mannewa ko rashin daidaituwa ba. Don aikin rufewa, muna amfani da bencin gwajin rufewa don tabbatar da matakin kariya na IP65 na bearings, muna kwaikwayon yanayin ƙura da hazo na ruwa don ci gaba da aiki na tsawon mintuna 30, da kuma kimanta juriyar ƙura da ruwa na zoben rufewa da mai mai shafawa don tabbatar da amincin bearings a cikin mawuyacin yanayi na aiki.
5. Binciken girgiza da hayaniya - Cikakken kimantawa na aikin aiki mai ƙarfi
Matakan girgiza da hayaniya suna da mahimmanci wajen tantance yanayin lafiyar bearings. Mun samar da tsarin nazarin girgizar Bruel & Kjaer (tare da kewayon mita na 5Hz - 20kHz) da kuma na'urar nazarin bearings ta Schaeffler FAG don tattarawa da kuma nazarin spectra na girgizar kowace saitin bearings da aka gama. Ta hanyar kwatanta iyakokin spectra na ƙa'idodin ƙasa da ƙasa kamar ISO 15242, za mu iya gano lahani na ciki daidai kamar lalacewar hanyar tsere, lalacewar ƙwallo mara daidaituwa, ko lahani na keji. Bearings masu inganci na yau da kullun suna kiyaye ƙarancin matakan girgiza da hayaniya yayin aiki.
Shida. Gwajin Nauyi Mai Sauƙi da Dorewa - Tabbatar da Ƙarfin Ɗaukan Nauyi
Domin tabbatar da ƙarfin ɗaukar bearings da tsawon lokacin sabis na bearings a ƙarƙashin yanayin aiki na ainihi, mun yi amfani da injin gwajin gajiya na Instron hydraulic servo (tare da matsakaicin nauyin 250kN) don gudanar da gwaje-gwajen nauyi masu ƙarfi. Mun tabbatar da aikin bearings a ƙarƙashin nauyin axial na ≥ sau 1.5 ƙimar da aka kimanta kuma mun tabbatar da cewa hauhawar zafin jiki yayin aiki na tsawon awanni 200 bai wuce 45℃ ba. A lokaci guda, mun ƙididdige tsawon lokacin da aka kimanta bisa ga ma'aunin ISO 281:2007 don tabbatar da cewa tsawon lokacin L10 shine ≥ awanni 10,000.
VII. Dubawar Kamanni da Dubawar Masana'antu ta Ƙarshe - Wurin Duba Ingancin Ƙarshe
Kafin a kammala marufin, dole ne a yi wa kowace saitin bearings cikakken bincike ta amfani da na'urar hangen nesa da kuma na'urar hangen nesa ta gani don duba duk wani lahani kamar tsatsa, tsatsa, ƙaiƙayi, ko gogewa a saman. Haka kuma ana duba ingancin fenti na gidan bearings da kuma maganin saman don tabbatar da cewa alamun da bayanan marufi sun bayyana kuma cikakke. Ana gwada ƙimar maganadisu da ta rage don tabbatar da bin ƙa'idodin JB/T 6641. Ana yin rikodin duk bayanan gwaji a ainihin lokaci kuma ana shigar da su cikin tsarin don cimma "bin diddigin lamba ɗaya" - kowane saitin bearings da aka samar za a iya bin diddigin su zuwa ga tarin kayan aiki, tsarin sarrafawa, da bayanan gwaji.
