Washer-grower - ib tug yooj yim tshuaj rau ib tug complex teeb meem

Txuas hu ua fasteners ua los ntawm ntau yam ntaub ntawv, dua li ntawm hlau los yog yas. Lawv daim ntawv no yog feem ntau yeej, tab sis muaj lwm yam (square, ib los yog txawm polygonal). Lawv yog tsim los faib cov load thaum screwing hauv lub neeg rau, bolts, screws, bolts, pins thiab lwm yam hais ntawm threaded kev sib txuas, los mus tiv thaiv dents thiab lwm yam kev puas tsuaj li zoo li los xyuas kom meej zoo hluav taws xob sib cuag.

Tab sis tseem muaj tej yam txawv washer. Grover muaj ib tug tshwj xeeb lub hom phiaj.

Kev teeb meem thiab nws cov tshuaj

Lub ceev ceev txoj kev loj hlob ntawm mechanical engineering, uas tshwm sim nyob rau hauv lub thib ob ib nrab ntawm cov XIX xyoo pua, tau qhia ib tug tseem ceeb tsis muaj threaded sib txuas. Cov neeg kho tshuab load, co, thiab ntau yam mus qhov chaw oscillation ntshav mechanism ua, nyob rau hauv tas li ntawd mus qaug zog failures, cov kev hem thawj ntawm txawj yuav txo tau ntawm lub dag lub zog ntawm lawv cov tebchaw. Ceev thiab bolts loosening, thiab mus saib xyuas lawv mob, yuav tsum tau lub sij hawm thiab kev rau siab. Nyob rau tib lub sij hawm, riveted kev sib txuas, screwed qub lwm, ua nws yooj yim mus lauj thiab, thiaj li, kev engineering kev pab, yog ua nce tsis yooj yim. Tshwj xeeb tshuab ntxhua khaub ncaws-grower yog cov tshuaj rau qhov teeb meem no.

hauv paus ntsiab lus ntawm cov lag luam

Tag nrho cov ingenious yog yooj yim qauv, thiab ua hauj lwm flawlessly. Washer-grower yog ib tug kauj caij nplooj ntoos hlav los yog ib tug nplhaib nrog ib tug txoj kab txiav yog me ntsis nkhaus yog li ntawd tus kis diverge nyob rau hauv ib lub tsheb uas txwv tsis pub txoj kev sib hloov ntawm lub noob txiv thaum nws yog unscrewed. Thaum lub sij hawm rau pem hauv ntej lub cev, tsis muaj dab tsi tiv thaiv lub zog ntawm cov kho txhais tau tias muaj bolts (screws los yog pins) thiab ceev. Tab sis thaum koj sim tig lub ntse ntug tom nws nyob rau hauv kev coj rov qab mus rau lub hlau thiab hinders qhov kev txiav txim.

Qhov twg puas tau lub npe "grower"?

Muaj ob lub ntsiab versions ntawm yog vim li cas lub caij nplooj ntoos hlav tshuab ntxhua khaub ncaws grower yog hu ua. Raws li cov thawj, nws twb immortalized lub npe ntawm lub inventor. Qhov no assumption yog txaus siab los ntawm qhov tseeb hais tias txog rau thaum ntxov fifties, lo lus "Grover" nyob rau hauv Soviet kev cov ntaub ntawv twb sau ntawv nrog ib tug capital tsab ntawv. Tom qab lub Soviet Union launched rau phiaj los nqis tes tiv thaiv tsis tau txawv teb chaws lus, raws li lub ces linguists tsuas txhaws li cov "kuj zoo kawg thiab haib", transistors lub npe hu ua triodes, resistors - Kuj thiab cov Puck-grower yog renamed nyob rau hauv caij nplooj ntoos hlav, los yog tsawg kawg xav kom sau li no lub sij hawm me me ntawv.

Qhov thib ob version ntawm lub keeb kwm ntawm lub sij hawm yog raws li nyob rau hauv nws liam kev sib raug zoo nrog cov kawm lus Askiv lo lus "Loj hlob", lub ntsiab lus "kev loj hlob". Yog hais tias koj xav metaphorically, lub zog clamped fasteners, qhov ntau nws resists, vim hais tias ntawm nws cov xwm caij nplooj ntoos hlav, washer-grower. Ib tug los ntawm unscrewing nws straightens, thiab nws cov nyiaj pab ntau tshaj transverse dimension nce, uas yog loj hlob.

Tag nrho cov fasteners, ua nyob rau hauv peb lub teb chaws, nruj me ntsis qauv. Yog tsis muaj kev zam thiab lub Puck-grower. GOST 6402-70 kom meej meej txhais lub txhua yam khoom ntawm lub "tshuab ntxhua khaub ncaws", cov ntaub ntawv los ntawm qhov uas lawv ua, thiab cov geometric qhov ntev uas lawv ua hauj lwm. Qhov no yog vim li, los ntawm no, thaum xub thawj siab ib muag, theem nrab los ua ke unit yuav yog nyob ntawm seb kev nyab xeeb lag luam los ntawm txoj machine.
