Washers yog hu ua fasteners ua los ntawm ntau yam ntaub ntawv, feem ntau yog hlau los yog yas. Lawv cov duab feem ntau yog annular, tab sis nws kuj tuaj yeem sib txawv (square, rectangular thiab txawm polygonal). Lawv tau tsim los faib cov khoom thauj thaum tsav tsheb ceev, ntsia hlau, ntsia hlau, bolts, studs thiab lwm yam threaded fasteners, los tiv thaiv dents thiab lwm yam kev puas tsuaj, thiab xyuas kom zoo hluav taws xob tiv tauj.

Tab sis kuj muaj ib qho txawv txawv puck. Tus cog muaj lub hom phiaj tshwj xeeb.

Technical problem and solution

Txoj kev loj hlob sai ntawm kev siv tshuab engineering, uas tshwm sim nyob rau hauv ib nrab ntawm lub xyoo pua XIX, qhia txog qhov tsis muaj kev sib txuas ntawm threaded. Mechanical loads, kev vibration thiab ntau yam kev vibrations ntawm qhov txav ntawm cov mechanism units tshwm sim, ntxiv rau kev qaug zog tsis ua hauj lwm, kev hem thawj ntawm spontaneous txo lawv lub zog.kev sib txuas. Cov txiv ntseej thiab bolts tau unscrewed, thiab txhawm rau tswj lawv tus mob, kev siv zog thiab sijhawm yuav tsum tau ua. Nyob rau tib lub sijhawm, cov pob qij txha riveted, uas yog lwm txoj hauv kev rau threaded sawv daws yuav, ua disassembly thiab, yog li ntawd, txij nkawm ntawm cov cuab yeej, uas ua ntau thiab ntau nyuaj, nyuaj. Lub tshuab ntxhua khaub ncaws tshwj xeeb yog qhov kev daws teeb meem rau qhov teeb meem no.

Txoj Cai Ua Haujlwm

Txhua yam kev txawj ntse yog npaj yooj yim, tab sis nws ua haujlwm tsis zoo. Grover ntxhua khaub ncaws yog ib lub caij nplooj ntoos hlav los yog lub nplhaib slotted, me ntsis khoov kom qhov sib txawv ntawm qhov kev taw qhia uas tiv thaiv cov txiv ntoo los ntawm kev sib hloov thaum nws tsis muaj ntswj. Thaum lub sij hawm rau pem hauv ntej stroke, tsis muaj dab tsi cuam tshuam nrog lub zog ntawm lub fastening unit, muaj xws li ib tug ntsia liaj qhov rooj (ntsia hlau los yog stud) thiab ib tug txiv ntseej. Tab sis thaum koj sim tig nws mus rau qhov tsis sib xws, cov ntug ntse khawb rau hauv cov hlau thiab ua rau qhov kev txiav txim no nyuaj.

lub npe "grover" tuaj qhov twg?

Muaj ob lub ntsiab ntawm vim li cas lub caij nplooj ntoos hlav ntxhua khaub ncaws hu ua li ntawd. Raws li thawj zaug, lub npe ntawm tus inventor yog immortalized. Qhov kev xav no tau txais kev txhawb nqa los ntawm qhov tseeb tias txog thaum pib ntawm lub tsib caug lo lus "Grover" nyob rau hauv Soviet cov ntaub ntawv txuj ci tau sau nrog ib tsab ntawv loj. Tom qab kev sib tw tawm tsam cov lus txawv teb chaws pib nyob rau hauv lub USSR, raws li cov linguists, uas tsuas yog clogged lub "zoo thiab muaj zog", transistors pib hu ua triodes, resistors - resistances, thiab Grover washer tau renamed mus rau hauv lub caij nplooj ntoos hlav, los yog. Nyob rau hauv qhov xwm txheej hnyav nws raug pom zoo kom sau cov lus me me no.

Qhov thib ob ntawm lub hauv paus chiv keeb ntawm lo lus yog raws li nws txoj kev sib raug zoo nrog lo lus Askiv "Grow", txhais tau tias "kev loj hlob". Yog hais tias koj xav figuratively, ces lub zog ntawm fastening kev twb kev txuas yog clamped, qhov ntau nws resists, vim nws lub caij nplooj ntoos hlav xwm, Grover washer. Thiab thaum unscrewing, nws straightens, thiab nws qhov siab tshaj plaws transverse dimension nce, uas yog, loj hlob.

Txhua cov fasteners tsim nyob rau hauv peb lub teb chaws yog nruj me ntsis standardized. Lub puck-grover yog tsis muaj kev zam. GOST 6402-70 kom meej meej tswj cov khoom siv ntawm "caij nplooj ntoos hlav ntxhua khaub ncaws", cov ntaub ntawv uas lawv tau tsim, thiab qhov ntev geometric uas lawv tau ua. Tsis muaj ib yam dab tsi uas xav tsis thoob hauv qhov no, kev nyab xeeb ntawm kev ua haujlwm ntawm lub tshuab ua haujlwm yuav nyob ntawm qhov no, thaum xub thawj siab ib muag, chav tsev sib dhos thib ob.
