Disiki itaziguye hamwe na rotary servomotor: Umubare wibyiza byo gushushanya: Igice cya 1

Intego zo Kwiga

• Sisitemu nyayo-rotary servo sisitemu igwa mubikorwa byiza kubera ubushobozi bwa tekinike.
• Ubwoko butandukanye bwa rotomoteri ikora irashobora gutanga inyungu kubakoresha, ariko buriwese afite ikibazo cyihariye cyangwa imbogamizi.
• Serivise itaziguye izenguruka itanga imikorere myiza, ariko irazimvye kuruta moteri.

Kumyaka mirongo, serivise zikoreshwa mubikoresho byabaye kimwe mubikoresho bisanzwe mubikoresho byo gutangiza inganda. Ibikoresho bya sevromotors bitanga umwanya, guhuza umuvuduko, gufata ibyuma bya elegitoronike, kuzunguruka, guhagarika umutima, guhuza porogaramu no guhuza neza imbaraga za servomotor kumuzigo. Ibi bitera kwibaza: ni servomotor ikozwe neza niyo nzira nziza ya tekinoroji yo kuzunguruka, cyangwa hari igisubizo cyiza?

Mw'isi itunganye, sisitemu ya roto ya roto yaba ifite torque n'umuvuduko uhuye na progaramu kuburyo moteri itaba nini cyangwa nini. Ihuriro rya moteri, ibintu byohereza, hamwe nuburemere bigomba kugira torsional itagira ingano hamwe na zeru inyuma. Kubwamahirwe, sisitemu nyayo izunguruka servo sisitemu igwa kuriyi ntego kurwego rutandukanye.

Muri sisitemu isanzwe ya servo, gusubira inyuma bisobanurwa nko gutakaza kugenda hagati ya moteri n'umutwaro uterwa no kwihanganira imashini y'ibikoresho byohereza; ibi birimo igihombo icyo aricyo cyose muri bokisi, umukandara, iminyururu, hamwe. Iyo imashini yabanje gukoreshwa, umutwaro uzareremba ahantu hamwe hagati yo kwihanganira imashini (Ishusho 1A).

Mbere yuko umutwaro ubwawo ushobora kwimurwa na moteri, moteri igomba kuzunguruka kugirango ifate ubunebwe buriho mubintu byohereza (Ishusho 1B). Iyo moteri itangiye kwihuta kurangiza kwimuka, umwanya wumutwaro urashobora rwose kurenga umwanya wa moteri nkuko umuvuduko utwara umutwaro urenze umwanya wa moteri.

Moteri igomba kongera gufata akajagari mu cyerekezo gitandukanye mbere yo gukoresha itara ku mutwaro kugirango ryihute (Ishusho 1C). Uku gutakaza kwimuka kwitwa gusubira inyuma, kandi mubisanzwe bipimwa muminota arc, bingana na 60/60 byimpamyabumenyi. Gearbox yagenewe gukoreshwa hamwe na servo mubikorwa byinganda akenshi bifite ibyasubiwemo kuva kuri 3 kugeza 9 arc-iminota.

Gukomera kwa Torsional ni ukurwanya kugoreka moteri ya moteri, ibintu byohereza, hamwe numutwaro mugusubiza ikoreshwa rya torque. Sisitemu itagira umupaka yakwirakwiza torque kumuzigo nta mpande zingana zijyanye na axis yo kuzunguruka; icyakora, niyo icyuma gikomeye kizunguruka gato munsi yumutwaro uremereye. Ubunini bwo gutandukana buratandukana hamwe na torque ikoreshwa, ibikoresho byoherejwe, n'imiterere yabyo; mu buryo bwimbitse, birebire, ibice byoroheje bizahinduka kuruta bigufi, binini. Uku kurwanya kugoreka nibyo bituma amasoko ya coil akora, nkuko guhagarika impinduramatwara impinduramatwara buri cyerekezo cyinsinga; insinga zibyibushye zikora isoko ikomeye. Ikintu cyose kitarenze ubukana bwa torsional butagira umupaka gitera sisitemu gukora nkisoko, bivuze ko imbaraga zishobora kubikwa muri sisitemu nkuko umutwaro urwanya kuzunguruka.

Iyo uhujwe hamwe, gukomera kwa torsional gukomera no gusubira inyuma birashobora gutesha agaciro imikorere ya sisitemu ya servo. Gusubira inyuma birashobora kumenyekanisha ukudashidikanya, nkuko moteri ya moteri yerekana umwanya wa shitingi ya moteri, ntabwo aho gusubira inyuma byatumye umutwaro uhagarara. Backlash itangiza kandi ibibazo byo guhuza nkibintu bitwara imitwaro hamwe no gukuramo moteri muri make mugihe umutwaro na moteri bihindura icyerekezo. Usibye gusubira inyuma, gukomera kwa torsional bitagira ingano bibika ingufu muguhindura zimwe mumbaraga za kinetic ya moteri hanyuma ikaremerera imbaraga zishoboka, ikarekura nyuma. Uku kurekura ingufu gutinda gutera umutwaro kunyeganyega, gutera resonance, kugabanya inyungu zishobora gukoreshwa muguhindura kandi bigira ingaruka mbi kubisubizo no kugena igihe cya sisitemu ya servo. Mubibazo byose, kugabanya gusubira inyuma no kongera ubukana bwa sisitemu bizongera imikorere ya servo kandi byoroshe guhuza.

Rotary axis servomotor iboneza

Ibikoresho bisanzwe bizunguruka ni rotomeri ya servomotor hamwe na kodegisi yubatswe kugirango ibone ibitekerezo hamwe na garebox kugirango ihuze itara ryaboneka n'umuvuduko wa moteri kuri moteri isabwa n'umuvuduko wumutwaro. Gearbox nigikoresho gihoraho cyamashanyarazi nikigereranyo cya transformateur yo guhuza imitwaro.

Ibikoresho byanonosoye ibikoresho bikoresha disiki itaziguye ya rotom servomotor, ikuraho ibintu byohereza muguhuza imitwaro na moteri. Mugihe iboneza rya gearmotor ikoresha guhuza kugiti gito cya diameter, sisitemu yo gutwara ibinyabiziga ihindura umutwaro kuri rotor nini cyane. Iboneza bikuraho gusubira inyuma kandi byongera cyane gukomera kwa torsional. Umubare muremure wa pole hamwe na torque ndende ya moteri itwara moteri itaziguye ihuye na torque hamwe nihuta biranga moteri ifite moteri ya 10: 1 cyangwa irenga.
