Monga kampani yopanga zinthu yodziwika bwino popanga zinthumabearing a pilo block, nthawi zonse timaona ubwino wa malonda ngati njira yothandiza kwambiri pakampani yathu. Posachedwapa, kampani yathu yalengeza mwalamulo kuti yamaliza kukonza makina owunikira, ndikukhazikitsa njira yowunikira "yonse, yosiyana siyana, komanso yolondola" kuyambira polowera zinthu zopangira mpaka potuluka. Cholinga cha polojekitiyi ndikupereka zinthu zabwino kwambiri, zodalirika komanso zolimba kwa makasitomala apadziko lonse lapansi ndi miyezo yowunikira yokhwima komanso njira zowunikira zonse.
Ma bearing a pillow block amagwiritsidwa ntchito kwambiri mu makina a zaulimi, zida zonyamulira, makina opangira migodi, zida zopumira mpweya, ndi zina zotero. Kugwira ntchito kwawo kumakhudza mwachindunji kukhazikika ndi moyo wa zida. Kuti tikwaniritse zofunikira za mikhalidwe yosiyanasiyana yogwirira ntchito, kampani yathu imatsatira mosamalitsa miyezo yamakampani monga GB/T 27555-2011 “Rolling Bearings – Bearing Caps with External Spherical Surfaces” ndi JB/T 8875-2001, ndipo imagwiritsa ntchito njira zonse zowongolera khalidwe pa seti iliyonse ya ma bearing. Zomwe zili mkati mwa kukweza kwa dongosolo lowunikirali ndi izi:
1. Kuyang'anira zinthu zopangira - Kuyang'anira ubwino kuchokera ku gwero
Zipangizo zopangira zapamwamba kwambiri ndiye maziko a ma bearing apamwamba. Timayang'anira zinthu mosamala pa gulu lililonse la zitsulo ndi ma castings omwe akubwera, pogwiritsa ntchito ma Thermo Scientific direct reading spectrometers kuti tiwunikire bwino kapangidwe ka mankhwala a zipolopolo za bearing ndi zinthu zozungulira (ndi kulondola kwa kusanthula kwa zinthu mpaka 0.001%). Timaonetsetsa kuti kapangidwe ka zinthuzo kakukwaniritsa zofunikira zonse. Nthawi yomweyo, kudzera mu mayeso olimba, timawongolera kukula kwa kuuma kwa pamwamba pa Rockwell (HRC 58-62) ndi kuuma kwapakati (HRC 25-35) kuti tiwonetsetse kuti kukana kuwonongeka ndi kulimba bwino. Zipewa zoponyera zimawunikidwa chimodzi ndi chimodzi kuti ziwone ngati pali zolakwika pamwamba monga ming'alu, ma pores, ndi ma canage.
2. Kulondola kwa kukula ndi mawonekedwe a zigawo - Kutsata luso lapamwamba
Kulondola kwa ma bearing caps okhala ndi malo ozungulira akunja kumatsimikizira mwachindunji ubwino wawo wosonkhanitsira ndi magwiridwe antchito. Pa gawo lokonza zigawo, timagwiritsa ntchito zida zoyezera za Mitutoyo zolumikizana zitatu (zolondola za 1.5 μm) kuti tisonkhanitse ndikuyesa deta yamitundu yambiri ya m'mimba mwake wamkati, m'mimba mwake wakunja, m'lifupi, ndi kulolerana kwa mabowo a mipando. Nthawi yomweyo, timagwiritsa ntchito ma gauge ozungulira ndi ma profile mita kuti tiwunike bwino zolakwika za kuzungulira, cylindricality, ndi mawonekedwe ozungulira a mphete zamkati ndi zakunja za ma bearing. Kupatuka kwa malire a miyeso yofunika monga kutalika kwapakati kwa pamwamba pa bolodi kumayendetsedwa mosamala mkati mwa mulingo wokhazikika. Pakukhwima kwa pamwamba, timagwiritsa ntchito ma profilometer a Keyence atatu-dimensional surface kuti tiwonetsetse kuti kukhwima kwa Ra ≤ 0.2 μm.
3. Kuunikira kolondola kwa ma radial ndi kuwunika kozungulira - Kuonetsetsa kuti ntchito ikuyenda bwino
Kutuluka kwa ma radial ndi kulondola kozungulira ndiye zizindikiro zazikulu zoyezera magwiridwe antchito a ma bearing. Timagwiritsa ntchito njira yolumikizirana ya mfundo zitatu kuti tiyese kutuluka kwa ma radial mkati mwa ma bearing kuti tiwonetsetse kuti akuyendetsedwa bwino mkati mwa mulingo woyenera wa 0.05-0.15 mm, mogwirizana ndi zofunikira za ISO5753:2009. Pakuyesa kulondola kozungulira, timagwiritsa ntchito ma laser interferometers kuti tizindikire kuthamanga kwa axial (≤ 0.03 mm) ndi kuthamanga kwa radial (≤ 0.05 mm), kuonetsetsa kuti ma bearing ndi olondola panthawi yogwira ntchito mwachangu.
4. Kusinthasintha kozungulira ndi kuwunika magwiridwe antchito otseka - Kuyerekeza momwe zinthu zilili pantchito yeniyeni
Kusinthasintha kozungulira kumakhudza mwachindunji magwiridwe antchito a zida. Pambuyo poti gulu lililonse la ma bearing lasonkhanitsidwa, limayesedwa kuzungulira ndi manja ndi kuzindikira kuchuluka kwa zinthu pogwiritsa ntchito choyezera mphamvu kuti liwone ngati kuzungulira kuli kosalala, popanda kumamatira kapena phokoso losazolowereka. Kuti titseke bwino, timagwiritsa ntchito benchi yoyesera kutsekereza kuti titsimikizire mulingo woteteza wa IP65 wa ma bearing, kutsanzira fumbi ndi malo osungira madzi kuti agwire ntchito mosalekeza kwa mphindi 30, ndikuwunika kukana kwa fumbi ndi madzi kwa mphete zotsekereza ndi mafuta odzola kuti zitsimikizire kudalirika kwa ma bearing m'mikhalidwe yovuta yogwirira ntchito.
5. Kusanthula kugwedezeka ndi phokoso - Kuwunika kwathunthu kwa magwiridwe antchito
Kugwedezeka ndi kuchuluka kwa phokoso ndi njira zofunika kwambiri poyesa thanzi la ma bearing. Tinakonza makina owunikira kugwedezeka kwa Bruel & Kjaer (okhala ndi ma frequency range a 5Hz - 20kHz) ndi Schaeffler FAG bearing analyzer kuti asonkhanitse ndikusanthula ma vibration spectra a seti iliyonse ya ma bearing omalizidwa. Poyerekeza malire a ma spectral a miyezo yapadziko lonse lapansi monga ISO 15242, titha kuzindikira molondola zolakwika zamkati monga kuwonongeka kwa raceway, kusagwira bwino kwa mipira, kapena zolakwika za khola. Ma bearing abwinobwino amakhala ndi kugwedezeka kochepa komanso phokoso panthawi yogwira ntchito.
Chisanu ndi chimodzi. Kuyesa kwa Mphamvu ndi Kulimba - Kutsimikizira kwa Kunyamula Mphamvu
Kuti titsimikizire mphamvu ya bearing ndi moyo wautumiki wa ma bearing pansi pa mikhalidwe yeniyeni yogwirira ntchito, tinagwiritsa ntchito makina oyesera kutopa a Instron hydraulic servo (omwe ali ndi katundu wolemera wa 250kN) kuti tichite mayeso othamanga. Tinatsimikizira momwe ma bearing amagwirira ntchito pansi pa axial loads a ≥ 1.5 nthawi ya mtengo wovotera ndipo tinatsimikiza kuti kutentha kumakwera panthawi yogwira ntchito mosalekeza kwa maola 200 sikudutsa 45℃. Nthawi yomweyo, tinawerengera moyo wovotera motsatira muyezo wa ISO 281:2007 kuti titsimikizire kuti moyo wa L10 ndi ≥ maola 10,000.
VII. Kuyang'ana Maonekedwe ndi Kuyang'ana Komaliza kwa Fakitale - Malo Omaliza Oyang'anira Ubwino
Asanamalize kulongedza, gulu lililonse la ma bearing liyenera kuyesedwa mosamala pogwiritsa ntchito ma microscope owonera komanso ma microscope owonera kuti aone ngati pali zolakwika monga ming'alu, dzimbiri, mikwingwirima, kapena mikwingwirima pamwamba. Ubwino wa utoto wa nyumba ya bearing ndi kukonza pamwamba kumawunikidwanso kuti zitsimikizire kuti zolemba ndi zambiri zolongedza zili zomveka bwino komanso zathunthu. Mtengo wotsalira wa maginito umayesedwa kuti zitsimikizire kuti zikutsatira malamulo a JB/T 6641. Deta yonse yoyesera imalembedwa nthawi yeniyeni ndikulowetsedwa mu dongosolo kuti ikwaniritse "kutsata code imodzi" - gulu lililonse la ma bearing omwe amapangidwa limatha kutsatiridwa mpaka ku gulu la zinthu zopangira, njira yogwiritsira ntchito, ndi zolemba zoyesera.
Kudzipereka kwa Makasitomala
Kukonzanso kwathunthu kwa makina oyesera ndi kudzipereka kwathu kolimba ku filosofi ya "ubwino woyamba". Kuyambira kufika pa zinthu zopangira mpaka kumaliza ntchito yomalizidwa, njira iliyonse, gawo lililonse, ndi mayeso aliwonse zimadalira miyezo yapadziko lonse lapansi komanso zosowa za makasitomala. Timamvetsetsa kuti zomwe timapereka kwa makasitomala sizinthu zongoyerekeza chabe, koma ndi kudzipereka kwakukulu ku magwiridwe antchito okhazikika a zidazo.
Mtsogolomu, tidzapitiliza kukonza njira zoyesera ndikuyambitsa zida zapamwamba zoyesera kuti tipatse makasitomala apadziko lonse lapansi ntchito zabwino kwambiri zamtundu wazinthu. Takulandirani makasitomala atsopano ndi akale kuti adzacheze fakitale yathu kuti akalandire malangizo ndikuwona kufunafuna kwathu kosasunthika kwamtundu wabwino pamodzi!
