Ntsiab -Xov Xauv Rau Aerospace Cav Casings: Installation, Specs & QC - Xov Xwm

Ntsiab -Xov Xwm Ntxig rau Aerospace Cav Casings

Peb muaj machined threaded inserts rau cav thiab gearbox vaj tse rau ntau tshaj nees nkaum xyoo, thiab casings yog qhov twg threaded fastening tau nyuaj: nyias phab ntsa, cyclic loads, thiab siab kub. Ib tug stripped xov ntawm ib tug tiav txhuas los yog titanium rooj plaub yog kim kho.Ntsiab -locking insertsdaws qhov no los ntawm decoupling lub load- bearing xov los ntawm niam txiv cov ntaub ntawv thiab ntxiv ib tug zoo mechanical xauv.

Dab tsi yog qhov yuam sij -Locking (Pin-Locked) Ntxig?

Tus yuam sij -locking insert - kuj hu ua apin-locked insertlos yog los ntawm lub npe nrov Keensert - yog ib qho khoom siv nrog cov xov sab hauv rau lub ntsia liaj qhov rooj thiab cov xov sab nraud uas ntsia hlau rau hauv lub qhov tapping. Nws lub ntsiab lus txhais yog ib txheej ntawm cov yuam sij kaw nyob rau hauv cov qhov nyob rau sab nraud txoj kab uas hla.

Tom qab qhov ntxig ntxig zaum hauv qab ntawm qhov chaw, cov yuam sij raug thawb los ntawm kev sib tsoo ntawm cov niam txiv - cov ntaub ntawv xov, mechanically locking lub insert tiv thaiv kev sib hloov. Qhov no yog dab tsi muab cov ntxig rau nws lub siab torque - tawm thiab rub - tawm tsis kam, thiab yog vim li cas nws thiaj li muaj sia nyob kev co zoo dua li lub bushing. Cov me me, sib zog dua- qhov ntau thiab tsawg ua haujlwm nqa ob lub yuam sij tawm tsam; loj dua, siab dua - load loj nqa plaub.

Rau cov ntsiab lus, ob npaug -kawg stud yog qhov sib koom ua ke ntawm cov pob qij txha no - ib tug txiv neej txoj xov mus tas li rau nutting Cheebtsam ntawm thiab tawm - tab sis qhov ntxig yog qhov teeb meem nyuaj thiab ua kom pom tseeb ntawm no.

Installation, ib kauj ruam ntawm kauj ruam

The first step in installing a key-locking insert is drilling the hole The second step in installing a keensert is tapping the hole The third step in installing a key-locking insert is running the insert The fourth step in installing a key-locking insert is driving the key of the insert The fifth step in installing a key-locking insert is inspecting the insert

Laum.Xaiv lub laum rau qhov loj me me; qhov tob sib npaug sib npaug ntev ntxiv txog 1-2 mm. Chamfer lub qhov ncauj (feem ntau 1 × 45 degree), deburr thiab huv si.
Coj mus rhaub.Txiav cov xov sab nraud nrog rau qhov tshwj xeeb ntxig kais uas phim cov ntxig OD xov - tsis yog tus qauv tshuab kais. Tshawb xyuas nrog go/no-go gauges; lub qhov yuav tsum tsis muaj chips.
Khiav qhov ntxig rau hauv.Siv tus tsav tsheb kom raug, khiav qhov ntxig rau hauv squarely kom txog thaum nws lub ntsej muag sab saum toj zaumhauv qab ntawm qhov chaw, feem ntau 0.1-0.3 mm down los yog ib spec. Ib qho kev nkag siab zoo siab yog qhov tsis lees paub.
Tsav cov yuam sij.Nrog rau qhov sib txuam tseem ceeb punch, tsav lub xauv cov yuam sij ncaj nraim mus txog thaum lawv zaum tag nrho thiab yaug, tsis muaj qaij. Qhov no yog cov kauj ruam uas kaw qhov chaw, thiab qhov twg feem ntau qhov chaw tsis ua haujlwm pib.
Tshawb xyuas.Paub meej tias tsis muaj qhov txav txav, yaug cov yuam sij, lub ntsej muag hauv qab, thiab cov xov sab hauv dhau mus / tsis yog - mus ntsuas.

Drilling, tapping, khiav-hauv thiab nias qhov tseem ceeb tuaj yeem muab tso rau hauv CNC / servo chaw nres tsheb nrog quab yuam- tswj qhov tseem ceeb. Qhov txiaj ntsig tiag tiag yog rov ua dua ntawm tus yuam sij - nias cov kauj ruam ntxiv rau cov ntaub ntawv traceable thiab qhov tob - tsis yog ceev xwb.

Cov ntaub ntawv, Xov & Standards

Display of key locking threaded inserts in various specifications

Inserts feem ntau muab rau hauv cov pa roj carbon steel (feem ntau plated), 303/304 CRES rau kev siv dav hlau dav hlau, thiab A286 lossis npib tsib xee-puag alloys rau kub- ntu pob qij txha. Internal threads ua raws li daim ntawv thov: Unified inch (UNC/UNF) rau ASME B1.1, metric rau ISO 261/965, los yog tswj - vojvoog- hauv paus profile ntawm NASM8879 rau kev thov cov pob qij txha.

Txoj cai spec yogMIL-I-45914A(Ntxig, Ntsia Hlau Xov - Xauv Hauv, Ntsiab Xauv), nrog rau cov qauv xws liTIAB SA 51830thiabNAS 1394hais tawm tsam nws. Tawm tawm tsam cov spec thiab cov khoom siv niam txiv, tsis yog lub npe nrov.

Tej yam uas peb tiv thaiv

Tsis muaj chamfer ntawm lub qhov→ qhov ntxig hla - pib thiab muab cov xov tshiab. Txhua zaus chamfer thiab deburr.
Ntxig sawv kev txaus siab→ cuam tshuam nrog lub ntsej muag mating. Lub rooj zaum hauv qab no, txheeb xyuas txhua lub sijhawm.
Crooked los yog ib nrab tsav yuam sij→ tuaj yeem tawg tus thawj coj lossis tsis kaw, tom qab ntawd loosen hauv vibration. Siv lub punch square thiab xyuas cov yuam sij yog flush.

Feem ntau ntawm cov no yog cov txheej txheem -kev qhuab qhia tsis ua haujlwm, uas yog vim li cas semi-automation them tawm.

Cov Ntawv Sau

Ntsiab -locking insertsraug nqi ntau dua thiab ntxiv ib kauj ruam dhau hlau (helicoil) cov ntxig, thiab lawv tau dhau mus rau qhov qis-load, qis- kev vibration kho. Rau cov qauv, siab - kev vibration thiab siab - kub casing pob qij txha, tus nqi yuav kev ntseeg tau koj yuav tsis khuv xim. Thaum muab khoom, hais cov spec, cov xov sab hauv (xauv vs. tsis yog -locking), thiab niam txiv cov khoom, thiab nug seb cov kais dej thiab cov cuab yeej siv puas suav nrog. Rau cov khoom siv dav hlau, yuav cov ntawv pov thawj, tsis yog cov khoom siv xwb.

FAQ

Ntsiab -locking insert vs. helicoil?

Lub helicoil yog ib co coiled xaim - pheej yig dua thiab sib dua, tab sis tsis muaj qhov zoo xauv tshwj tsis yog siv lub kauj vab xauv. Ib tug yuam sij-locking insert yog ib tug khoom bushing nrog tsav cov yuam sij rau ntau dua torque- tawm thiab rub- tawm tsis kam.
