Dab tsi yog Lock Washers thiab Lawv Ua Haujlwm Li Cas?
Lock washers yog hom caij nplooj ntoos hlav ntxhua khaub ncaws tsim lostiv thaiv cov txiv ntseej thiab bolts los ntawm loosening vim kev co, torque, lossis dynamic loads. Tsis zoo li cov tshuab ntxhua khaub ncaws, uas faib cov khoom sib npaug, cov tshuab ntxhua khaub ncaws ua kom nrujntxiv kujmus zog. Lawv tuaj nyob rau hauv ntau yam designs-split, hniav, conical, thiab wedge-tag nrho optimized rau sib txawv siv.
Piv txwv li:
-
Split lock washers(helical) ua hauj lwm los ntawm kev tom rau hauv ob lub txiv ntoo thiab cov khoom siv hauv paus.
-
Cov hniav ntxuav hniav sab nraudmuab kev sib txhuam ntawm qhov chaw mos.
-
Wedge lock washersmuab kev ua haujlwm zoo heev hauv qhov chaw muaj kev vibration siab.
Txhua qhov sib txawv yog tsim los ntxiv cov txheej txheem tseem ceeb ntawm kev tiv thaiv xoob.
Vim li cas Lock Washers tseem ceeb tshaj qhov koj xav
Hauv ntau qhov kev lag luam -aerospace, kev tsim kho, automotive, thiab machinery- kev ntseeg siab ntawm kev sib koom ua ke yog tsis sib tham. Kev vibration lossis kev txav mus tas li tuaj yeem ua rau me me hloov hauv cov fasteners uas nws thiaj li ua rau tsis ua haujlwm.
Ib tug raug xaiv xauv washer:
-
Txhim kho bolt preload raws sijhawm
-
Txo qhov xav tau kom rov nruj dua
-
Minimizes qhov kev pheej hmoo ntawm cov nqi tu lossis tsis ua haujlwm
Qhov no yog qhov tshwj xeeb tseem ceeb hauvlong-span assemblies, los yog thaum ua hauj lwm nrog cov ntaub ntawv xws li txhuas uas yuav nthuav los yog cog lus raws sij hawm.

Tsis muaj lub tshuab ntxhua khaub ncaws, txawm tias qhov tseeb torqued ntsia liaj qhov rooj yuav:
-
Rov qab tawm vim kev vibration
-
Hla hauv qab thermal cycling
-
Ua tsis tau raws li kev hloov pauv

-
Lub tshuab ntxhua khaub ncaws: Sib piv cov qauv tsim (sib cais, hniav, npoo) rau koj cov ntaub ntawv siv tshwj xeeb.
-
Kev kho saum npoo: Zinc plating lossis dub oxide tuaj yeem txhim kho kev ua haujlwm ntev.
-
Qhov loj me sib phim: Lub tshuab ntxhua khaub ncaws yuav tsum haum snugly kom ua tau zoo.
Hauv kev ua haujlwm precision, ib txwm txheeb xyuas nrog torque + kev vibration xeem kom ntseeg tau tias kev ua haujlwm zoo.
