Dab tsi yog Axial Torsion Spring?
Koj xav tau lub caij nplooj ntoos hlav uas twists, tab sis lo lus "axial torsion caij nplooj ntoos hlav" tsis meej pem. You're unsure if it's a special component or just another name for a standard torsion spring.
Lub caij nplooj ntoos hlav axial torsion yog tus qauv helical caij nplooj ntoos hlav tsim los muab kev sib hloov quab yuam, los yog torque. Nws ua hauj lwm nyob ib ncig ntawm ib tug ncej los yog arbor, with the force being applied in a circular path perpendicular to the spring's central axis. Nws yog hom feem ntau ntawm torsion caij nplooj ntoos hlav[^ 1].
Hauv kuv lub xyoo ntawm kev tsim khoom, I've noticed that engineers, tshwj xeeb tshaj yog cov tshiab rau kev tsim mechanism, qee zaum tau ntes tau nyob rau hauv terminology. Lawv tuaj rau kuv nug rau "axial" caij nplooj ntoos hlav, xav tias lub zog ua raws li axis, zoo li lub caij nplooj ntoos hlav compression. Lub npe yog me ntsis yuam kev. Qhov "axis" yog dab tsi lub caij nplooj ntoos hlav mounted ntawm; txoj haujlwm nws ua yog txhua qhov kev sib hloov. Qhia meej txog qhov yooj yim no feem ntau yog thawj kauj ruam los tsim kom muaj kev vam meej, txhim khu kev qha ib feem rau lawv cov khoom.
Nws txawv li cas ntawm Extension lossis Compression Spring?
Koj pom lub caij nplooj ntoos hlav coiled thiab tej zaum yuav xav tias tag nrho cov coils ua haujlwm ib yam nkaus. This can lead to selecting the completely wrong type of spring for your application's force requirements.
Lub axial torsion caij nplooj ntoos hlav ua haujlwm los ntawm kev sib tw (lub tsho), thaum compression thiab extension caij nplooj ntoos hlav[^2]s ua hauj lwm nrog linear quab yuam (thawb thiab rub). Lawv lub hom phiaj tseem ceeb thiab txoj hauv kev khaws cia lub zog sib txawv kiag li.
Kuv nco qab txog qhov pib uas tab tom tsim cov khoom siv me me nrog lub hau pop-up. Lawv thawj tus qauv siv lub caij nplooj ntoos hlav compression me me los thawb lub hau qhib, tab sis nws xav tias tshee thiab tswj tsis tau. Lawv xa kuv cov qauv tsim, thiab kuv tuaj yeem pom tam sim ntawd lawv tau sim daws qhov teeb meem kev sib hloov nrog kev daws teeb meem. Peb hloov nws nrog me me axial torsion caij nplooj ntoos hlav[^3] haum nyob ib ncig ntawm lub pob khawm. Lub hau ces qhib nrog ib tug du, tswj cov lus tsa suab. It was a perfect example of how choosing the right type of force—rotational instead of linear—completely changed the user's experience.
