Vim li cas Fasteners Loosen?

Loosening Mechanisms - Vibration, Impact, Thermal Cycling, So kom txaus

Fastener loosening tshwm sim los ntawm ntau yam mechanisms. Kev vibration-induced loosening yog feem ntau - cyclic transverse motion ntawm cov xov flanks ua rau cov txiv ntseej tig mus rau tus ntsia liaj qhov rooj, nce zuj zus txo preload. Kev cuam tshuam kev thauj khoom tuaj yeem ua rau kev sib cais ib ntus ntawm qhov sib koom ua ke, tso cai rau cov txiv ntoo rov qab. Thermal cycling los ntawm cov txheej txheem los yog ib puag ncig qhov kub hloov pauv tsim qhov sib txawv ntawm cov khoom sib koom ua ke, ua rau muaj kev hloov pauv ua ntej thiab muaj peev xwm loosening. Kev so (embedment) tshwm sim thaum qhov chaw sib cuag ntawm cov xov, txiv ntseej lub ntsej muag, thiab cov tswv cuab sib koom ua ke nyob rau hauv kev txhawb nqa, txo cov khoom ua ntej dhau sijhawm.

Rotational vs Non-Rotational Loosening

Rotational loosening muaj qhov sib txawv ntawm cov txiv ntoo thiab cov ntsia liaj qhov rooj, feem ntau tshwm sim los ntawm kev vibration transverse uas kov yeej xov kev sib txhuam. Qhov no yog hom kev phom sij ntau dua vim tias nws tuaj yeem ua rau ua tiav qhov poob ntawm preload thiab sib cais sib cais. Tsis yog -kev hloov pauv tau tshwm sim los ntawm embedment, creep, los yog thermal cuam tshuam uas txo preload yam tsis muaj xov rotation. Txawm tias tsis tshua muaj kev ua yeeb yam, tsis yog - kev hloov pauv tuaj yeem ua rau muaj kev sib koom ua ke, ua rau muaj kev ntxhov siab ntxiv, thiab thaum kawg loosening yog tias preload poob qis dua qhov tseem ceeb rau kev sib koom ua haujlwm.

Peb Pawg ntawm Kev Xauv Cov Cai

Kev sib txhuam locking tsub kom qhov kev tiv thaiv rau xov rotation los ntawm kev tsim kom muaj kev sib txhuam ntau dua ntawm cov xov los yog ntawm lub ntsej muag txiv ntseej thiab cov kabmob nto. Piv txwv muaj xws li nylon insert xauv ceev, deformed xov xauv ceev, thiab caij nplooj ntoos hlav ntxhua khaub ncaws. Kev ntsuas qhov zoo siv lub cev tsis muaj zog los tiv thaiv kev sib hloov, xws li cotter pins los ntawm lub tsev fuabtais txiv ntseej, xaim kev nyab xeeb, lossis tab ntxhua khaub ncaws khoov rau ntawm qhov chaw tiaj tus. Cov tshuaj locking siv anaerobic adhesives kho nyob rau hauv cov xov sib txawv, sib txuas cov xov ua ke nrog tswj kev tawg - xoob torque.

Nylon Insert Lock Ceev (Nylock)

Lub hauv paus ntsiab lus - Nylon Nplhaib Embeds rau hauv xov, Kev sib txhuam tiv thaiv kom xoob

Nylon ntxig cov txiv ntseej suav nrog cov khoom siv polymer (feem ntau nylon 6/6) lub nplhaib nyob ruaj khov nyob rau sab saum toj ntawm cov txiv ntoo. Thaum cov txiv ntseej yog threaded rau lub ntsia liaj qhov rooj, lub nylon nplhaib yog elastically deformed los ntawm cov ntsia liaj qhov rooj xov, tsim ib tug compressive tuav uas resists kev sib hloov. Cov ntaub ntawv nylon lub cim xeeb kom ntseeg tau tias qhov kev kaw haujlwm kaw tau tswj xyuas ntau lub voj voog sib dhos. Standard nylon insert lock txiv ntseej yog ntsuas kub rau kwv yees li 120 degree, thaum siab -kub nylon variants txuas qhov no mus rau 250℃.

Reusability thiab Standards

Nylon ntxig cov txiv ntseej tuaj yeem siv tau 5-15 zaug ua ntej lub nplhaib nylon plam nws cov khoom siv rov qab thiab lub xauv lub zog poob qis dua qhov tshwj xeeb. Lub reusability nyob ntawm thread loj, bolt khoom hardness, nto tiav, thiab sib dhos torque. Lub nplhaib nylon yuav tsum raug tshuaj xyuas rau kev hnav lossis kev puas tsuaj ua ntej txhua qhov rov siv dua. Cov qauv muaj xws li DIN 982 (thin), DIN 985 (tus qauv), thiab ASTM A194 qib nrog rau -NL cov lus qhia txog kev ntsuas lub ntsuas phoo (piv txwv li, 2H-NL).

Tag nrho -Metal Locknuts

Sab saum toj Xauv / Deformed Xov - Sab saum toj xov Deformation tsim kev sib txhuam

Tag nrho -cov txiv ntseej xauv hlau ua tiav los ntawm kev siv tshuab deformation ntawm cov xov saum toj kawg nkaus. Sab saum toj ntawm cov txiv ntoo yog deformed tawm ntawm puag ncig los yog compressed, tsim kom muaj kev cuam tshuam nrog cov bolt threads thaum cov txiv ntseej sib sau ua ke. Tsis zoo li nylon ntxig rau txiv ntseej, tag nrho - hlau xauv ceev tsis muaj qhov kub thiab txias los ntawm polymer degradation, ua rau lawv haum rau siab - qhov kub thiab txias txog 650℃thiab tshaj rau cov khoom tsim nyog. Lawv muab kev rov siv tau zoo dua li cov nylon ntxig hom, feem ntau 10-20 cycles.

Slotted txiv ntoo / Tsev fuabtais txiv ntoo - Siv nrog Cotter Pin

Tsev fuabtais txiv ntoo muaj qhov txiav los ntawm sab saum toj uas sib haum nrog lub qhov drilled los ntawm lub bolt, tso cai rau tus pin cotter muab tso rau qhov zoo xauv. Qhov no yog txoj kev txhim khu kev ruaj ntseg zoo tshaj plaws, siv rau hauv cov ntawv thov tseem ceeb xws li kev hloov kho lub log, kev sib txuas ntawm lub kauj, thiab cov khoom raug tshem tawm qhov kev puas tsuaj tsis tuaj yeem zam tau. Lub cotter tus pin muab ib qho kev tiv thaiv txhua yam uas zoo tiv thaiv kev sib hloov ntawm cov txiv ntoo hauv txhua qhov xwm txheej.

Xov Xauv Adhesives

Txoj Cai - Anaerobic Adhesive Cures hauv Oxygen- Ib puag ncig dawb

Anaerobic xov locking adhesives tseem ua kua nyob rau hauv lub xub ntiag ntawm oxygen tab sis kho sai heev thaum nyob hauv cov pa oxygen - ib puag ncig dawb ntawm cov xov. Cov nplaum kho tau sau cov xov tshem tawm, tsim kom muaj ib daim ntawv cog lus uas tiv thaiv loosening los ntawm kev co. Cov khoom lag luam Loctite (tam sim no Henkel) yog lub npe nrov tshaj plaws, nrog cov xim -coded zog: 222 (liab, tsis muaj zog, tshem tau), 243 (xiav, nruab nrab lub zog, lub hom phiaj dav dav), 262 (liab, siab zog, ruaj khov), thiab 272 (liab, kub kub). Daim ntawv thov yuav tsum tau huv, qhuav threads - roj, roj, los yog lwm yam kab mob yuav txo tau lub zog ntawm daim ntawv cog lus.

Kev tshem tawm thiab kev ntseeg tau

Tsawg- lub zog xov lockers (Loctite 222) tuaj yeem disassembled nrog cov cuab yeej txheem tes. Nruab nrab -lub zog (243) yuav tsum muaj kev siv zog ib txwm siv tab sis tuaj yeem raug tshem tawm. Siab -lub zog (262) yuav tsum tau cua sov rau 250℃kom soften cov nplaum ua ntej tshem tawm. Xov lockers muab kev ruaj ntseg xauv thoob plaws ntau yam kev khiav hauj lwm xws li kub caij tsheb kauj vab, tshuaj lom neeg raug, thiab kev co, tab sis yog ib leeg - siv - cov txiv ntseej thiab ntsia liaj qhov rooj yuav tsum tau ntxuav thiab cov nplaum tshiab siv rau kev sib dhos.

Xauv Kev Xaiv Cov Lus Qhia

For high vibration conditions such as rotating equipment, reciprocating machinery, and vehicle suspensions, the recommended solution is Nord-Lock wedge lock washers combined with medium-strength thread locker for maximum reliability. High temperature applications (>150℃) yuav tsum tau tag nrho - hlau xauv ceev vim nylon inserts yuav degrade. Qhov kub thiab txias ib puag ncig nrog kev vibration nruab nrab tau txais txiaj ntsig zoo los ntawm cov nylon ntxig cov txiv ntoo lossis lub caij nplooj ntoos hlav ntxhua khaub ncaws rau kev daws teeb meem. Daim ntawv thov uas yuav tsum tau nquag disassembly yuav tsum siv lub caij nplooj ntoos hlav ntxhua khaub ncaws los yog deformed xov xauv ceev. Ib qho - lub sij hawm mus tas li tuaj yeem siv tau siab - lub zog xov xauv rau tus nqi tshaj plaws - kev kaw haujlwm zoo.

Locking Effectiveness Sib piv (Junker Test)

Junker transverse vibration test yog tus qauv kev lag luam rau kev ntsuas qhov ntsuas qhov ntsuas qhov ua tau zoo. Qhov kev sim no siv cyclic transverse txav mus rau qhov sib koom ua ke thaum ntsuas qhov seem seem preload. Cov txiaj ntsig kev ntsuas tsis tu ncua qhia tau tias Nord-Lock wedge lock washers tuav qhov siab tshaj qhov seem preload (feem ntau 80-90% tuav) nyob rau hauv kev co hnyav. Nylon insert xauv ceev khaws cia kwv yees li 60-70% preload. Lub caij nplooj ntoos hlav ntxhua khaub ncaws feem ntau khaws 30-50% preload thiab paub tias muaj kev ua haujlwm tsawg nyob rau hauv kev vibration siab. Xov locking adhesives khaws 70-85% nyob ntawm seb cov qauv tsim thiab daim ntawv thov zoo.
