Xa iinjineli zichaza a umzi-mveliso we-level shaft roller, abagcini nje ngokuyalela icandelo elijikelezayo-bakhetha ujongano olubalulekileyo phakathi kokulawula ukunyakaza kunye nokunyaniseka kwesakhiwo. Kwiinkqubo ze-winch eziphezulu, iimpompo ze-hydraulic, okanye iindibano zokulinganisa ngokuchanekileyo, i-shaft roller ithwala imithwalo ye-cyclic torsional, i-radial misalignment, kunye noqhagamshelwano lwe-abrasive. Ukuphambuka kwe-0.02 mm ekujikelezeni kunokukhawulezisa ukuthwala ukunxiba nge-40%. Ukwahluka kwe-5% kubulukhuni bomhlaba kumema i-micro-pitting ngaphakathi kweeyure zokusebenza ezingama-200. Kungenxa yoko le nto ukukhangela ingekho malunga nexabiso ngekhilogram. Imalunga nokuhambelana kwe-metallurgical, ukuthotyelwa kwe-GD&T kwinqanaba ngalinye, kunye nokunyamezela i-batch-to-batch kulwakhiwo lweenkozo.
Isizathu Sokuba Ukukhetha Izinto Zezinto Eziphathekayo Kumisele Intsebenzo—Kungekhona Nje Ngoomatshini
Uninzi lweentsilelo lubuyela emva kunobangela omnye: ukuziphatha ngendlela engafanelekanga phantsi koxinzelelo lwehlabathi lokwenyani. Iirola ezisemgangathweni ze-42CrMo4 ziyaqhekeka xa zibekwe kwindawo yeoli ene-sulfide etyebileyo. Ukwahluka kwe-AISI 4140 delaminate phantsi kokulayisha okuphindaphindiweyo kwempembelelo kwiifestile zeemoto zobunjineli. Siye sabona abathengi abathathu abahlukeneyo betshintsha iirola rhoqo emva kweenyanga ezi-3-de batshintshela kwi-AMS 5387 cobalt alloy. I-matrix yayo yechromium-tungsten iyaxhathisa kwi-650°C. Ubume bayo obuhle be-dendritic bubambe i-Ra ≤ 0.4 µm emva kokusila kokugqibela-okubalulekileyo ekulandeleni i-lip ye-seal. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Asazi "umatshini kuqala, sivavanye kamva." Siqinisekisa i-billet chemistry ekrwada ngaphambi kokuphosa, siqinisekise ukwahlulwa kwe-interdendritic nge-SEM-EDS, emva koko siqinisekise ukuhanjiswa kobulukhuni kuwo wonke amacandelo anqamlezayo sisebenzisa imephu yeVickers encinci. Yonke i-T800-based leveler shaft roller ithwala ukulandeleka okugcweleyo kobushushu-hayi nje inombolo yesatifikethi, kodwa iilogi zomjikelo we-thermal wokwenyani kunye ne-tensile curves evela kwiziko elifanayo.
Udibaniso oluthe nkqo luSombulula into efihlwa yi Outsourcing
Abanye ababoneleli bangaphandle bakhupha, besebenza, kunye nokugqiba ukwahlula abathengisi. Oko kudala iindawo ezingaboniyo: indlu yesanti-cast inokuba ne-subsurface porosity engabonakaliyo kwi-NDT-kodwa ibonakaliswe kuphela emva kokuba i-CNC yokugaya isusa isandi sangaphandle. Abanye batsiba unyango lobushushu de kube yindibano yokugqibela, bebeka umngcipheko wokugqwetheka ngexesha lokucinywa kwejiyometri egqityiweyo. I-QINGDAO QIANGSENYUAN iqhuba i-investment casting, i-multi-axis CNC yokujika (ukuya kwi-B-axis swiveling), unyango lobushushu be-vacuum, kunye nokupholisa i-electro-indawo enye eqinisekisiweyo ye-ISO 9001. Kwindlu yesilinda yempompo yepiston enejenali ezidityanisiweyo zerola, sisebenza ngomatshini ibhore *phambi* kokuqina-emva koko sigaya i-post-temper ukuze sibambe ±0.005 mm cylindricity ngaphezu kwe-300 mm ubude. Akukho handoffs. Akukho kukhukuliseka kwe-dimensional. Akukho kutshintshwa-tyala xa i-Cpk yehla ngaphantsi kwe-1.33.
Ukuqinisekiswa Kwehlabathi Lokwenyani Kubetha IiNgcaciso zePhepha
Abathengi bayabuza: "Ngaba i-level shaft roller yakho ingaphatha i-12,000 psi pulsation + 1,800 rpm?" Siphendula ngedatha-hayi izithembiso. Kulo nyaka uphelileyo, siye savavanya izinto ezihlukeneyo ezintandathu phantsi komsebenzi ofanisiweyo wewintshi engaselunxwemeni: ukutyhileka kwesitshizi setyuwa iiyure ezingama-250, ukuguqulwa kwetorque eyi-10⁶, kunye nokukhwela ibhayisekile komthwalo oqhubekayo ukusuka ku-0 ukuya kwi-220 kN. Kuphela i-AMS 5387 kunye nokuguga kwezigaba ezimbini (isisombululo se-1,100 ° C + 850 ° C / 4h + 650 ° C / 16h) idlulile ngaphandle kokuqhekeka komphezulu okanye ukuqina kwehla> 3 HRC. Insimbi engenasici i-17-4PH ayiphumelelanga kumjikelo we-780,000. Yiyo loo nto iprotocol yethu yokuhlola ibandakanya i-100% ye-ultrasonic scanning ye-discontinuities yangaphakathi-kwaye kutheni yonke imithwalo ibandakanya ingxelo yedijithali kunye ne-CMM scan overlays ngokuchasene ne-CAD yegama, kungekhona nje ukudlula / ukungaphumeleli kwezitampu.
Indlela Yokuchaza Okulungileyo—Ukususela Kumzobo Ukuya Ekuhanjisweni
Qala ngenjongo yokusebenza-kungekhona ijometri. Endaweni ye-"Ø120 mm × 450 mm," chaza: "Kufuneka idlulise i-85 kN-m torque ngelixa igcina i-≤ 0.015 mm yokuphuma emva kwenkonzo ye-5,000 yeyure kwi-ISO VG 68 ye-oyile yezimbiwa kwi-80 ° C kwindawo." Emva koko vumela i umzi-mveliso we-level shaft roller Isikhokelo sokukhethwa kwezinto, ukulandelelana kokuphatha ukushisa, kunye nokugqiba. Senza iflegi yongquzulwano lwe-GD&T-njengokuchaza unyamezelo lwendawo kwindawo eyenziwe ngoomatshini emva konyango lobushushu, apho intsalela yoxinzelelo izakutshintsha indawo ngokungalindelekanga. Iinjineli zethu zibuyisela imizobo echazwe kwiiyure ze-48, zigxininisa imingcipheko yokwenziwa kwezinto, ziphakamisa ezinye ii-alloys, kunye nokucaphula ixesha elikhokelayo kuzo zombini ii-prototype (iiveki ezi-4) kunye ne-medium-volume (iiveki ze-12-15) imiyalelo. Akukho nto imangalisayo. Akukho kuphinda kusebenze. Akukho kuhanjiswa kade.
Kwizicelo ezibalulekileyo zemishini apho ukungaphumeleli kuthetha ixesha lokuphumla, umngcipheko wokhuseleko, okanye ukungathotyelwa kwemithetho—ukuchaneka akukhethi. Yenziwe ngobunjineli, iqinisekisiwe, kwaye ihanjiswa. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. yakha i-level shaft rollers ezisindayo-hayi nje ukujikeleza. Umsebenzi wabo uqala kwakudala ngaphambi kokuba i-chip yokuqala ibhabha: kwiilebhu zesayensi yezinto, isoftware yemodeli ye-thermal, kunye namashumi eminyaka yempendulo yenkqubo yempompo. Yileyo ndlela i-roller iba yi-anchor ethembekileyo.
