Sekambani yekugadzira inonyanya kugadziramabheyaringi epapiro, tinogara tichiona kunaka kwechigadzirwa senzira yekubatsira kambani yedu. Munguva pfupi yapfuura, kambani yedu yakazivisa zviri pamutemo kupedzwa kwekuvandudzwa kwakazara kwehurongwa hwekuongorora, ichigadzira nzira yekuongorora "yakazara, ine mativi akawanda, inoteverwa" kubva pakupinda kwezvinhu zvisina kugadzirwa kusvika pakubuda kwechigadzirwa chapera. Chirongwa ichi chine chinangwa chekupa zvigadzirwa zvemhando yepamusoro, zvakavimbika uye zvinogara kwenguva refu kune vatengi vepasi rose nematanho ekuongorora akaomarara uye maitiro ekuongorora akazara.
Mabheya epillow block anoshandiswa zvakanyanya mumichina yekurima, michina yekufambisa, michina yekuchera, michina yekufema, nezvimwewo. Kushanda kwawo kunokanganisa zvakananga kugadzikana uye hupenyu hwemichina. Kuti isangane nezvinodiwa zvakasimba zvemamiriro akasiyana ekushanda, kambani yedu inotevedzera zvakanyanya mitemo yeindasitiri yakaita seGB/T 27555-2011 “Rolling Bearings – Bearing Caps with External Spherical Surfaces” uye JB/T 8875-2001, uye inoshandisa kudzora kwemhando yepamusoro kweseti yega yega yemabheya. Zviri mukati mekuvandudzwa kwesystem iyi yekuongorora ndeizvi:
1. Kuongorora zvinhu zvisina kugadzirwa - Kudzora mhando kubva kwazvinogadzirwa
Zvinhu zvemhando yepamusoro ndizvo hwaro hwemabheringi emhando yepamusoro. Tinoita ongororo dzakasimba dzezvinhu pabhenji rega rega resimbi inouya uye ma castings, tichishandisa Thermo Scientific direct reading spectrometers kuti tiongorore zvakanyatsonaka makemikari ari muma shells e bearing uye zvinhu zvinotenderera (nekunyatsoongorora zvinhu kusvika ku 0.001%). Tinova nechokwadi chekuti zvinhu zvirimo zvinoenderana nezvinodiwa. Panguva imwe chete, kuburikidza nemiedzo yekuoma, tinodzora gradient ye surface Rockwell hardness (HRC 58-62) uye core hardness (HRC 25-35) kuti tive nechokwadi chekuti kupfeka kwakasimba uye kusimba. Ma casting caps anoongororwa chimwe nechimwe kuti aone kana paine zvikanganiso zve surface zvakaita sema cracks, pores, uye shrinkage cavities.
2. Kururama kwezvikamu uye chimiro - Kutsvaga kugona kukuru
Kururama kwemabearing caps ane nzvimbo dzakatenderera dzekunze kunoratidza zvakananga kunaka kwekubatanidzwa kwawo uye mashandiro awo. Munguva yekugadzirisa zvikamu, tinoshandisa Mitutoyo three-coordinate measurements (nekunyatsojeka kwe1.5 μm) kuunganidza nekuyedza data rine mativi akawanda remukati medhayamita, dhayamita rekunze, upamhi, uye kushivirira kwegomba rechigaro remabearing. Panguva imwe chete, tinoshandisa roundness gauges uye profile metres kuti tiongorore zvakanyatsonaka roundness, cylindricality, uye spherical shape ezvikanganiso zvemukati nekunze kwemabearing. Kutsauka kwemiganhu yehukuru hwakakosha senge centre height yespherical surface kunodzorwa zvakasimba mukati me standard range. Kune surface roughness, tinoshandisa Keyence three-dimensional surface profilometers kuti tive nechokwadi chekuti roughness Ra ≤ 0.2 μm.
3. Kuongororwa kweRadial Clearance uye Kutenderera Kwakarurama - Kuve nechokwadi chekuti kushanda zvakanaka
Kubviswa kweRadial uye kurongeka kwekutenderera ndizvo zviratidzo zvikuru zvekuyera mashandiro emabearing. Tinoshandisa nzira yekubata mapoinzi matatu kuyera kurongeka kwemukati kwemabearing kuti tive nechokwadi chekuti inodzorwa zvakanaka mukati mechiyero che 0.05-0.15 mm, zvichienderana nezvinodiwa ne ISO5753:2009. Pakuyedzwa kwekurongeka kwekutenderera, tinoshandisa laser interferometers kuona kumhanya kweaxial (≤ 0.03 mm) uye kumhanya kweradial (≤ 0.05 mm), tichiona kuti mabearing acho ari kutsvedzerera uye akarurama panguva yekushanda nekukurumidza.
4. Kuchinjika kwekuchinja-chinja uye kuongorora mashandiro ekuvhara - Kutevedzera mamiriro chaiwo ekushanda
Kuchinjika kwekutenderera kunokanganisa zvakananga mashandiro emidziyo. Mushure mekunge seti yega yega yemabheringi yaunganidzwa, inoongororwa nekutenderera nemaoko uye kuongororwa kwehuwandu ne torque tester kuti ione kana kutenderera kwacho kwakatsetseka, pasina kunamira kana ruzha rusina kujairika. Pakushanda kweseal, tinoshandisa sealing test bench kuti tione kana IP65 protection level yemabheringi, tichitevedzera guruva nemvura mhute kuti ishande kwenguva refu kwemaminitsi makumi matatu, uye tichiongorora guruva nemvura re sealing rings uye mafuta ekuzora kuti tive nechokwadi chekuti mabheringi acho akavimbika mumamiriro ekushanda akaoma.
5. Kuongororwa kwekudengenyeka uye ruzha - Kuongorora kwakazara kwekushanda kwesimba
Kudedera uye mwero weruzha inzira dzakakosha dzekuongorora hutano hwemabearings. Takaisa sisitimu yekuongorora vibration yeBruel & Kjaer (ine frequency range ye5Hz - 20kHz) uye Schaeffler FAG bearing analyzer kuti tiunganidze uye tiongorore vibration spectra yeese seti yemabearings akapedzwa. Nekuenzanisa miganhu yespectral yemitemo yepasi rose yakaita seISO 15242, tinogona kuona nemazvo zvikanganiso zvemukati zvakaita sekukuvadzwa kwemujaho, kusakara kwemabhora zvisina kuenzana, kana zvikanganiso zvekeji. Mabearings emhando yepamusoro akajairika anochengetedza mwero wakaderera wevibration uye ruzha panguva yekushanda.
Nhanhatu. Kuedza Kunorema uye Kugara Kwenguva Yakareba - Kusimbiswa Kwekugona Kutakura
Kuti tione kuti mabearing capacity uye hupenyu hwebasa remabearing pasi pemamiriro chaiwo ekushanda, takashandisa muchina weInstron hydraulic servo fatigue testing (une mutoro wepamusoro we250kN) kuti tiite dynamic load tests. Takaongorora mashandiro emabearing pasi peaxial loads ye ≥ 1.5 times rated value uye takaona kuti kukwira kwetembiricha panguva yekushanda kwenguva refu kwemaawa mazana maviri hakupfuure 45℃. Panguva imwe chete, takaverenga rated life zvichienderana neISO 281:2007 standard kuti tive nechokwadi chekuti L10 life iri ≥ 10,000 hours.
VII. Kuongorora Chitarisiko uye Kuongorora Kwekupedzisira Kwefekitori - Nzvimbo Yekupedzisira Yekutarisa Hunhu
Pamberi pekurongedza, seti yega yega yemabheringi inofanira kuongororwa zvakanyanya nemaziso uchishandisa kuona uye maikorosikopu emaziso kuti ione kana paine zvikanganiso zvakaita sekutsemuka, ngura, kukwenya, kana kukwenya pamusoro. Hunhu hwependi yeimba yemabheringi uye kugadziriswa kwepamusoro kunoongororwawo kuti kuve nechokwadi chekuti mamaki neruzivo rwekurongedza zvakajeka uye zvakakwana. Kukosha kwemagineti kunoongororwa kuti kuve nechokwadi chekutevedzera mitemo yeJB/T 6641. Ruzivo rwese rwekuyedza runonyorwa munguva chaiyo uye rwunopinzwa musystem kuti uwane "kutevedza kodhi imwe chete" - seti yega yega yemabheringi anogadzirwa inogona kuteverwa kumashure kune raw material batch, maitiro ekugadzirisa, uye zvinyorwa zvekuyedza.
Kuzvipira kweVatengi
Kuvandudzwa kwakazara kwehurongwa hwekuyedza ndiko kuzvipira kwedu kwakasimba kupfungwa yekuti "mhando yekutanga". Kubva pakupinda kwezvinhu zvakagadzirwa kusvika pakupera kwechigadzirwa chapera, maitiro ese, parameter yega yega, uye bvunzo yega yega zvinoenderana nezvinodiwa nevatengi. Tinonzwisisa kuti zvatinopa vatengi hazvisi kungoenderana nezvinodiwa chete, asi kuzvipira kwakasimba kukushanda kwakasimba kwemidziyo.
Mune ramangwana, ticharamba tichivandudza maitiro ekuyedza uye tichaunza michina yekuyedza yepamusoro kuti tipe vatengi vepasi rose masevhisi emhando yepamusoro ezvigadzirwa. Tinokugamuchirai vatengi vatsva nevakare kuti vashanyire fekitori yedu kuti vawane gwara uye tigoona kushanda kwedu pamwe chete mukutsvaga mhando!
