nkhani

Pamene pulojekiti ikufuna actuator yaying'ono yomwe imatha kugwira ntchito popanda brake yakunja, mota ya nyongolotsi nthawi zambiri imakhala chisankho chabwino kwambiri. Mndandanda wa TWG2534-180SH wa TT MOTOR umaphatikiza mota ya DC ya magnetite yokhazikika ya kukula kwa 180 ndi gearbox ya nyongolotsi ya 25×34mm, yomwe imapereka ma reduction ratios a 65:1 ndi 131:1. Worm drive imapereka maubwino awiri ofunikira: kuchepetsa kwambiri mu gawo limodzi ndi back-drive yodzitsekera yokha - zomwe zikutanthauza kuti output shaft singatembenuzidwe ndi mphamvu yakunja mota ikazima. Izi zimapangitsa TWG2534‑180SH kukhala yoyenera kugwiritsa ntchito monga valve actuation, lift tables, camera gimbals, ndi smart lock mechanisms.

Buku lotsogolera kusankha ili limakuthandizani kusankha mphamvu yoyenera yamagetsi ndi chiŵerengero chochepetsera kutengera liwiro lanu, mphamvu, ndi magetsi.

Gawo 1: Linganizani Kuchepetsa Chiŵerengero ndi Kuthamanga Kwanu ndi Zosowa Zanu za Torque

Chiŵerengero cha 65:1 ndi choyenera kugwiritsa ntchito zomwe zimafuna liwiro lapakati komanso mphamvu yochepa. Mwachitsanzo, gimbal yaying'ono ya kamera yomwe imafunika kuyendetsa pa liwiro la 70–80 rpm pansi pa katundu wopepuka (0.2–0.3 kg·cm) imagwira ntchito bwino ndi mtundu wa 12V womwe umayendetsa bokosi la gearbox la 65:1. Liwiro lotulutsa pansi pa katundu ndi 66 rpm, zomwe zimapangitsa kuti kayendedwe kake kakhale kosalala komanso kolamulidwa popanda kuchedwa kwambiri.

Chiŵerengero cha 131:1 chapangidwira zochitika za torque yapamwamba komanso yothamanga pang'ono. Ntchito zambiri zimaphatikizapo ma valve amagetsi, pomwe mota iyenera kuthana ndi kukangana koyambirira kenako ndikusunga malo a valve motsutsana ndi kuthamanga kwa madzi. Ndi mota ya 6V ndi gearbox ya 131:1, torque yotulutsa yovomerezeka ndi 0.9 kg·cm pa 45 rpm. Izi ndizokwanira kwambiri pa ma valve ambiri amkuwa a ½-inchi mpaka 1-inchi. Ngakhale mtundu wa 12V pa 131:1 umapereka 0.45 kg·cm pa 32 rpm, zomwe zimagwira ntchito bwino pa ma valve ang'onoang'ono apulasitiki kapena ma dampers.

Gawo 2: Sankhani Voltage Yoyenera ya Dongosolo Lanu

Ngati chipangizo chanu chikugwiritsa ntchito mphamvu ya batri (ma cell anayi a AA, paketi imodzi ya Li‑ion ya maselo awiri, kapena banki yamagetsi ya USB), sankhani mota ya 6V TFF‑180SH‑18140. Imapereka mphamvu yayikulu pa amp imodzi ndi mphamvu yotsika kuposa mtundu wa 12V. Mwachitsanzo, mota ya 6V ili ndi mphamvu yotsika ya 1271 g·cm (≈1.27 kg·cm) pa mphamvu yotsika ya 1.80A, pomwe mota ya 12V imakhazikika pa 710 g·cm yokhala ndi 0.42A yokha. Moto wa 6V ndi woyenera bwino kugwiritsa ntchito komwe mphamvu yoyambira yayikulu ndi yofunika - monga kumasula valavu yomata.

Ngati galimoto yanu ili m'gulu la magalimoto kapena mafakitale okhala ndi mphamvu yokhazikika ya 12V, mota ya 12V TFF‑180SH‑10400 ndi chisankho chachilengedwe. Mphamvu yake yotsika ya stall current (0.42A yokha) imachepetsa kupsinjika kwa magetsi ndi dera loyendetsa. Mtundu wa 12V umagwiranso ntchito mwachangu pang'ono pazigawo zonse ziwiri, zomwe zingakhale zabwino pakugwiritsa ntchito monga kusintha bedi lachipatala kapena kukweza miyendo ya olumala yamagetsi, komwe liwiro lapakati limakonda kuposa mphamvu yayikulu.

Gawo 3: Gwiritsani ntchito Self-Locking Feature

Chimodzi mwa zinthu zofunika kwambiri pa chida chochepetsera zida za nyongolotsi chokhala ndi ma ratio opitilira 30:1 ndi kudzitseka chokha. Ma ratio onse a 65:1 ndi 131:1 amakwaniritsa izi mokwanira. Injini ikayima, katundu womwe uli pa shaft yotulutsa sungathe kuyendetsa galimotoyo kumbuyo. Izi zimachotsa kufunikira kwa brake yamagetsi kapena sitima yovuta yamagetsi yokhala ndi makina ogwirira.

Mwachitsanzo, mu choyimilira cha TV chosinthika kutalika, mota imakweza nsanja kenako imayima. Popanda kudzitseka yokha, kulemera kwa TV kumatsitsa pang'onopang'ono nsanjayo pakapita nthawi. Ndi TWG2534‑180SH, nsanjayo imakhala pomwe imayima. Mofananamo, mu actuator ya solar tracker, motayo imasunga ngodya ya panel motsutsana ndi katundu wa mphepo popanda kugwiritsa ntchito mphamvu. Izi zimathandizanso kuti ziphaso zachitetezo cha zida zamankhwala ndi zonyamula zizikhala zosavuta.

Ntchito Zachizolowezi Mwachidule

Ma valve amagetsi a mpira ndi ma valve a chipata mwina ndi omwe amagwiritsidwa ntchito kwambiri pa injini iyi. Mtundu wa 6V wokhala ndi chiŵerengero cha 131:1 umapereka 0.9 kg·cm pa liwiro la 45 rpm - wokwanira kutembenuza valavu ya mpira wamkuwa ya ½-inch. Kudzitsekera kokha kumasunga valavu yotseguka kwathunthu kapena yotsekedwa kwathunthu popanda magetsi, zomwe ndizofunikira kwambiri pamakina othirira omwe amagwiritsa ntchito batire.

Makina ang'onoang'ono okweza ndi owongolera mzere amapindula ndi mphamvu yayikulu ya injini pa kukula kulikonse. Pa chosinthira kumbuyo kwa bedi lachipatala, mtundu wa 12V pa 65:1 umapereka mphamvu yotulutsa ya 0.22 kg·cm pa 66 rpm. Ndi makina olumikizira screw, izi zimasandulika kukhala mphamvu yolunjika ya 5–10 kg, yokwanira kusintha ntchito yopepuka.

Makamera achitetezo ndi zida zoyezera pan zimafuna kuyenda bwino komanso kuyimitsa bwino. Mota ya 12V yokhala ndi chiŵerengero cha 131:1 imayenda pa 32 rpm ikanyamula katundu, ndikutembenuza nsanja ya kamera pafupifupi masekondi 6-8 pa kuzungulira konse. Kukana kwachilengedwe kwa zida za nyongolotsi kumalepheretsanso kamera kusuntha chifukwa cha mphepo kapena kupsinjika kwa chingwe.

Makina ogulitsa makina nthawi zambiri amafunika kukankhira chinthu patsogolo kenako n’kugwira chinthu china. Mtundu wa 6V pa liwiro la 65:1 (90 rpm pansi pa katundu) umapereka liwiro labwino komanso mphamvu yogwiritsira ntchito zokhwasula-khwasula zopepuka kapena ma blister pack.

TT MOTOR imapereka mayeso a zitsanzo ndi kusintha kwapadera kuphatikiza kutalika kwa shaft, mtundu wa cholumikizira, ndi mafuta apadera opaka kutentha kwambiri. Lumikizanani ndi gulu lathu la mainjiniya kuti mukambirane za momwe mungagwiritsire ntchito.
