bearing phaj

Koj tshawb rau 'cov kabmob phaj' thiab koj tau txais ib txhiab dluab ntawm qhov zoo li qhov yooj yim, tiaj tus, feem ntau cov duab plaub nrog qee qhov hauv nws. Qhov ntawd yog thawj qhov kev xav tsis zoo nyob ntawd. Yog tias koj xav tias tag nrho nws yog, koj tab tom teeb tsa koj tus kheej kom mob taub hau ntawm qhov chaw. Nws tsis yog cov khoom lag luam uas koj tsuas yog xaiv los ntawm cov ntawv teev npe raws li thickness thiab qhov suav. Kev ua haujlwm tiag tiag, tus nqi tiag tiag, thiab qhov kev pheej hmoo tiag tiag tau muab zais rau hauv cov ntsiab lus feem ntau cov ntsiab lus gloss tshaj: kev ua siab ntev, lub qhov sib npaug, qhov xwm txheej ntawm ntug, thiab qhov tseem ceeb, kev cuam tshuam nrog lub fastener. Kuv twb pom tej yaam num ncua vim hais tias daim hlau tuaj txog nrog zeb nplai tuab li bearing phaj yuav tsis zaum yaug ntawm cov pob zeb, lossis vim tias lub qhov ntsia hlau tau raug xuas nrig, tawm hauv qhov me me conical burr uas cuam tshuam qhov nro. Nws yog cov ntsiab lus tsis zoo nkauj no uas cais cov khoom sib txuas uas tsuas yog zaum ntawm ib qho uas ua tau nws txoj haujlwm ntawm kev faib khoom thiab muab qhov ruaj khov, ruaj ntseg interface.

Dab Ntxwg Nyoog hauv Cov Lus Qhia: Khoom thiab Fabrication

Wb tham txog qib steel ua ntej. A36 muaj ntau, tab sis nws puas yog? Rau feem ntau cov ntawv thov zoo li qub, paub meej. Tab sis kuv nco qab txog txoj haujlwm retrofit hauv thaj chaw ntug hiav txwv uas peb tau teev A36 daim phiaj rau lwm qhov sib txuas. Tus neeg cog lus tau muab lawv los ntawm lub khw muag khoom dav dav, thiab hauv ib xyoos, qhov xeb ntawm qhov chaw yog qhov teeb meem tiag tiag. Tsis yog structural, tab sis ib tug tu npau suav phem. Peb yuav tsum tau thawb rau A588 los yog tsawg kawg tau txib lub khw muag khoom zoo. Tus nqi ntxiv ua ntej yuav txuag tau ntau heev. Nws yog ib tug txiav txim hu uas tau overlooked.

Ces muaj txiav. Sheared npoo yog pheej yig thiab ceev. Rau ntau sab hauv, tsis tseem ceeb daim hlau, zoo. Tab sis rau ib bearing phaj uas yog noj ncaj kem load los yog anchoring ib tug tseem ceeb nro cov tswv cuab, koj xav tau cov ntug nplaim-txiav los yog machined. Lub sheared ntug muaj kev ua haujlwm-hardening thiab micro-cracks. Nws tsis yog hais txog qhov zoo; nws yog hais txog kev tsim kom huv si, kwv yees kev thauj khoom los ntawm tus tswv cuab rau hauv lub phaj. Kuv kawm qhov no nyuaj heev thaum ntxov thaum lub phaj sheared nyob rau hauv ib tug hnyav ncej qhia ib tug hairline tawg los ntawm ntug thaum lub sij hawm soj ntsuam. Puas yog qhov ua rau? Tej zaum tsis yog, tab sis nws yog qhov ua rau.

Flatness. Qhov no loj heev. ASTM A6 muaj qhov kam rau ua, tab sis lawv dav. Rau lub phaj uas coj tus kab dav dav, koj xav tau ib yam dab tsi nruj dua. Peb feem ntau qhia tag nrho kev tiv thaiv kabmob uas, hauv kev xyaum, txhais tau tias tus neeg tsim khoom yuav tsum tau kuaj xyuas nws ntawm lub phaj nto thiab tej zaum txawm tias skim-mill nws. Kuv tau siv cov neeg muag khoom uas tau txais qhov no, zoo li Handan Zitai Fastener. Lawv nyob rau hauv qhov loj fastener hub hauv Yongnian, thiab thaum lawv paub txog bolts, lawv cov phaj ua haujlwm tau zoo vim tias lawv nkag siab cov txheej txheem fastener-phaj ua ib chav. Lawv tsis yog txiav hlau xwb; lawv tab tom ua ib qho kev sib txuas. Lawv qhov chaw nyob ze ntawm txoj kev thauj loj txhais tau hais tias lawv tau siv los thauj cov khoom hnyav, hnyav hnyav, uas yog qhov taw qhia kev thauj mus los uas koj txaus siab thaum koj tswj hwm qhov chaw nruj.

Nws yog ib qho System, Tsis yog ib feem cais

Qhov kev xav yuam kev loj tshaj plaws yog kev kho lub phaj thiab lub fastener raws li cov khoom sib txawv uas tau txais los ntawm cov neeg muag khoom sib txawv. Lub qhov nyob hauv bearing phaj tsis yog lub qhov xwb. Nws txoj kab uas hla, kam rau ua, thiab ua tiav dictate lub bolt qhov kev ua tau zoo. Tus qauv punched qhov feem ntau yog 1/16 loj dua lub ntsia liaj qhov rooj. Rau kev sib txuas snug-fit lossis bearing, qhov ntawd tsis zoo txaus. Koj xav tau remed lossis drilled qhov. Kev sib haum xeeb thaum lub sij hawm steel erection yuav ua npau suav phem yog hais tias lub qhov nyob rau hauv lub girder web, lub phaj, thiab cov khoom sib txuas tsis ua raws li vim hais tias lawv tag nrho cov fabricated rau txawv tolerances los ntawm txawv khw.

Peb pib bundling cov khoom thauj tog rau nkoj rods, leveling ceev, thiab lub hauv paus phaj nws tus kheej raws li ib tug khoom siv los ntawm ib tug neeg muag khoom. Nws hloov txhua yam. Cov xov sib txuam, cov qhov sib npaug, thiab cov galvanizing (yog tias xav tau) zoo ib yam. Nws tshem tawm qhov kev ua si liam ntawm tus neeg muag khoom fastener thiab tus neeg tsim khoom steel. Ib lub tuam txhab xws li Handan Zitai Fastener Manufacturing Co., Ltd. ua haujlwm hauv qhov chaw no zoo. Ua nyob rau hauv Tuam Tshoj tus qauv loj tshaj plaws nyob rau hauv lub hauv paus, lawv muaj cov ntsug kev koom ua ke los yog nruj tus neeg muag khoom tes hauj lwm los tswj tag nrho cov subsystem. Koj tsis yog yuav ib lub phaj xwb; koj tab tom yuav qhov tseeb interface.

Kev sib koom ua ke ntawm Washer yog lwm qhov hloov maj mam. Qee lub sij hawm xav tau ib lub tshuab ntxhua khaub ncaws sib cais hauv qab cov txiv ntoo. Lwm lub sij hawm, tshwj xeeb tshaj yog nrog cov phaj loj, cov khoom siv phaj nws tus kheej yog txaus los ua raws li cov kabmob nto. Qhov kev txiav txim siab hinges ntawm qib bolt, lub zog clamping, thiab cov khoom siv phaj lub zog. Kuv tau pom specs hu rau lub tshuab ntxhua khaub ncaws tsis tsim nyog, ntxiv cov nqi thiab ib feem ntxiv kom poob ntawm qhov chaw, thiab kuv tau pom cov specs tshem tawm qhov xav tau, ua rau cov txiv ntoo khawb rau hauv lub phaj thaum tensioning thiab txo cov preload zoo. Nws yog qhov nthuav dav me me nrog qhov tshwm sim tiag tiag.

Site Realities thiab Field Adjustments

Tsis muaj teeb meem zoo li cas lub khw kos duab, daim teb yog qhov sib npaug zoo. Qhob yeej tsis zoo kawg nkaus theem. Peb qhia kom meej grout nyob rau hauv lub hauv paus daim hlau rau ib tug yog vim li cas, tab sis hom grout thiab lub ncuav txoj kev tseem ceeb. Non-shrink, flowable grout yog tus qauv, tab sis kuv tau pom cov neeg ua haujlwm sim siv lub pob qhuav los yog mortar sib tov kom txuag tau sijhawm lossis nyiaj txiag. Qhov tshwm sim? Voids sub bearing phaj, ua rau taw tes loading thiab muaj peev xwm tawg thaum lub load tag nrho yog siv. Kev tshuaj xyuas yog qhov tseem ceeb, tab sis koj tsis tuaj yeem pom hauv qab phaj thaum nws tau teeb tsa.

Tom qab ntawd muaj cov classic lub qhov tsis kab. Lub instinct yog mus txog rau lub reamer los yog, phem, lub teeb. Peb muaj ib rooj plaub ntawm ib qhov project choj uas lub thauj tog rau nkoj ntsia liaj qhov rooj hloov thaum lub pob zeb nchuav. Cov phaj yuav tsis haum. Kev daws tsis yog kom elongate lub qhov nyob rau hauv tuab, qib 50 phaj ntawm qhov chaw - uas yuav muaj kev puas tsuaj. Peb yuav tsum tau soj ntsuam qhov ua haujlwm ntsia hlau ua haujlwm, xa cov ntaub ntawv rov qab mus rau tus neeg tsim khoom (uas, ua tsaug, tau teb thiab muaj peev xwm kho CNC), thiab tau txais daim hlau tshiab txiav. Nws raug nqi sij hawm, tab sis nws khaws cia qhov tsim kev ncaj ncees. Qhov yooj yim ntawm tus neeg muag khoom nrog kev hloov pauv sai thiab cov ntaub ntawv digital fabrication, feem ntau pom nyob rau hauv lub hauv paus kev lag luam zoo li Yongnian, dhau los ua ib txoj haujlwm txuag hauv lub sijhawm no.

Corrosion ntawm lub interface yog ib tug ntsiag to killer. Ib lub phaj hlau ntawm cov pob zeb tsim muaj peev xwm rau kev xeb corrosion, tshwj xeeb tshaj yog tias muaj noo noo. Peb qhia primer rau hauv qab, tab sis cov primer tau khawb tawm thaum lub installation. Nws yog ib tug yuav luag unsolvable teeb meem. Qee lub sij hawm ib daim ntawv nyias polyethylene yog siv, uas kuj pab nrog kev hloov kho, tab sis tom qab ntawd koj tau qhia txog txheej txheej compressible. Engineering yog tag nrho ntawm cov kev cuam tshuam no qhov twg cov phau ntawv kev daws teeb meem ntsib cov av nkos, tsis zoo tag nrho ntawm kev tsim kho.

Cov lus qhia los ntawm Kev Zoo Txaus Nraus

Thaum ntxov ntawm kuv txoj hauj lwm, kuv tau saib xyuas ib txoj hauj lwm hauv tsev rau khoom me me. Tus tsim hu ua yooj yim bearing daim hlau nyob rau hauv steel joists ntawm ib tug masonry phab ntsa. Tus neeg cog lus nug seb lawv puas tuaj yeem siv qee cov khoom seem seem ntawm lwm txoj haujlwm. Kuv txheeb xyuas qhov tuab-nws sib phim. kuv hais ok. Qhov kuv tsis tau kuaj yog lub zog tawm los. Nws yog qib qis dua. Cov phaj deformed me ntsis nyob rau hauv load, tsis txaus ua rau tsis ua hauj lwm, tab sis txaus los tsim ib tug pom deflection nyob rau hauv lub joists. Nws yog ib zaj lus qhia ntawm kev xav tias tsis muaj dab tsi. A bearing phaj yog ib qho kev tivthaiv. Txhua qhov teeb meem tseem ceeb: qib, thickness, qhov ntev, flatness, qhov. Koj tsis tuaj yeem pauv ib qho hloov pauv yam tsis tau kuaj xyuas lwm tus.

Lwm qhov ntxiab yog over-specifying. Tsis yog txhua lub phaj yuav tsum yog tus tswv. Rau lub teeb-gauge steel stud sill phaj, kub dov, sheared, thiab punched phaj yog zoo kawg nkaus txaus. Cov kos duab yog nyob rau hauv kev sib txawv ntawm ib tug tseem ceeb load txoj kev tivthaiv thiab ib tug nominal nthuav dav. Qhov kev txiav txim siab no yog los ntawm kev nkag siab txog qhov hnyav, qhov tshwm sim ntawm qhov tsis ua haujlwm, thiab kev tsim kho. Nws tsis yog ib qho loj-haum-tag nrho.

Thaum kawg, cov kabmob phaj embodies lub hauv paus ntsiab lus ntawm cov txheej txheem engineering: load hloov. Nws yog ib qho kev txo hwj chim, feem ntau overlooked tivthaiv uas ua rau kev sib txuas ntawm cov khoom sib txawv thiab cov tshuab ua tau. Kev muab nws los ntawm cov chaw tsim khoom paub uas kho nws ua ib feem ntawm lub kaw lus, tsis yog ib qho widget cais, yog ib nrab ntawm kev sib ntaus sib tua. Lwm ib nrab yog qhov tseeb, kev xav paub meej thiab cov lus qhia tshwj xeeb uas cia siab tias yuav muaj kev sib tw hauv ntiaj teb tiag tiag, tsis yog lub khw muag khoom zoo tagnrho. Nws yog txoj haujlwm tsis zoo uas ua kom cov qauv sawv.
