Ndi chochepetsera chiti chomwe chingakhale ndi stepper motor?

1. Chifukwa chomwe stepper motor ili ndi chochepetsera

Kuchuluka kwa kusintha kwa gawo la stator pagalimoto yotsika, monga kusintha kugunda kwa gawo la stepper motor drive kuti liziyenda mwachangu. Pamene otsika-liwiro stepper motor akudikirira stepper lamulo, rotor ali pa malo anaima. Mukamayenda pa liwiro lotsika, kusinthasintha kwa liwiro kumakhala kofunikira. Ngati isinthidwa kukhala ntchito yothamanga kwambiri, vuto la kusinthasintha kwa liwiro limatha kuthetsedwa, koma torque sikhala yokwanira. Kuthamanga kochepa kumayambitsa kusinthasintha kwa torque, pomwe kuthamanga kwambiri kumapangitsa kuti torque ikhale yosakwanira, chifukwa chake chotsitsa chimafunika.

 2. Kodi zochepetsera zomwe zimakhala ndi ma stepper motors ndi ziti?

Chochepetsera ndi chinthu chodziyimira pawokha chomwe chimapangidwa ndi kutumizira giya, kufalitsa nyongolotsi, ndi kufalitsa mphutsi zotsekeredwa mu chipolopolo cholimba. Amagwiritsidwa ntchito ngati chipangizo chochepetsera pakati pa galimoto yoyambira ndi makina ogwira ntchito, akugwira nawo ntchito yofananitsa liwiro ndi kutumiza torque pakati pa galimoto yoyamba ndi makina ogwira ntchito kapena actuator;

Pali mitundu yosiyanasiyana yochepetsera, yomwe ingagawidwe kukhala zochepetsera zida, zochepetsera nyongolotsi, ndi zida zochepetsera mapulaneti malinga ndi mtundu wapatsira; Malingana ndi magawo osiyanasiyana opatsirana, amatha kugawidwa kukhala ochepetsera siteji imodzi ndi masitepe ambiri;

Malinga ndi mawonekedwe a magiya, amatha kugawidwa kukhala zochepetsera ma cylindrical gear, ma bevel gear reducers, ndi bevel cylindrical gear reducers;

Malinga ndi kamangidwe ka kufalitsa, imatha kugawidwa kukhala zochepetsera zosawululidwa, zochepetsera zotulutsa, ndi zochepetsera coaxial.

Zochepetsera zomwe zili ndi ma stepper motors zimaphatikizapo zochepetsera mapulaneti, zochepetsera ma giya a nyongolotsi, zochepetsera magiya ofanana, ndi zochepetsera zida.

Kodi kulondola kwa stepper motor planetary reducer ndi chiyani?

Kulondola kwa chochepetsera, komwe kumadziwikanso kuti chilolezo chobwerera, kumatheka pokonza zotulukapo ndikuzizungulira molunjika komanso motsatana ndi wotchi kuti apange torque yovotera + -2% torque pamapeto pake. Pakakhala kusuntha kwakung'ono kumapeto kwa chochepetsera, kusamuka kumeneku kumatchedwa chilolezo chobwerera. Chigawochi ndi "arc miniti", yomwe ndi gawo limodzi mwa magawo asanu ndi limodzi a digiri. Chilolezo chobwereranso chimatanthawuza kumapeto kwa bokosi la gear.

The stepper motor planetary reducer ali ndi makhalidwe olimba kwambiri, kulondola kwambiri (mpaka 1 mfundo pa siteji), kuyendetsa bwino kwambiri (97% -98% pa siteji), chiŵerengero cha torque / voliyumu, komanso kukonza kwaulere.

Kulondola kwa kufalikira kwa mota ya stepper sikungasinthidwe, ndipo mawonekedwe ogwiritsira ntchito a stepper motor amatsimikiziridwa kwathunthu ndi kutalika kwa masitepe ndi nambala ya pulse. Nambala ya pulse imatha kuwerengedwa mokwanira, ndipo palibe lingaliro la kulondola mu kuchuluka kwa digito. Njira imodzi ndi imodzi, ndipo yachiwiri ndi masitepe awiri.

Kulondola komwe kwakhazikitsidwa pano ndikulondola kwa gear kubwereranso kwa gearbox ya pulaneti yochepetsera:

1. Njira yosinthira kulondola kwa spindle:

Kusintha kwa kulondola kwa kuzungulira kwa spindle ya pulaneti yochepetsera nthawi zambiri kumatsimikiziridwa ndi kunyamula ngati cholakwika cha makina a spindle chimakwaniritsa zofunikira.

Chinsinsi chosinthira kulondola kwa kuzungulira kwa spindle ndikusintha chilolezo chonyamula. Kusunga chilolezo choyenera ndi chofunikira pakugwira ntchito komanso moyo wazinthu za spindle.

Kwa mayendedwe ogubuduza, pakakhala kusiyana kwakukulu, sikuti katunduyo amangoyang'ana pazomwe akugudubuza molunjika ku mphamvu, komanso zingayambitsenso kupsinjika kwakukulu pakukhudzana pakati pa njira zamkati ndi zakunja za mayendedwe, kufupikitsa kunyamula moyo, ndikusuntha pakati pa spindle, zomwe ndizosavuta kuyambitsa kugwedezeka kwa zigawo za spindle.

Chifukwa chake, kusintha kwa ma bearings ogubuduza kuyenera kutsatiridwa kale kuti pakhale kusokoneza kwina mkati mwa mayendedwe, potero kutulutsa kuchuluka kwa zotanuka pakulumikizana pakati pa chinthu chogubuduza ndi njira zamkati ndi zakunja, potero kuwongolera kuuma kwa chonyamuliracho. .

2. Njira yosinthira kusiyana:

Chochepetsera mapulaneti chimapanga mikangano pakuyenda kwake, kuchititsa kusintha kwa kukula, mawonekedwe, ndi khalidwe lapamwamba la zigawozo, komanso kuvala ndi kung'ambika, zomwe zimabweretsa kuwonjezeka kwa chilolezo pakati pa zigawozo. Panthawiyi, tiyenera kusintha mkati mwa njira yoyenera kuti titsimikizire kulondola kwa kayendetsedwe kake pakati pa zigawozo.

3. Njira yolipirira yolakwika:

Chochitika chochotseratu zolakwika za zigawozo panthawi yomwe ikuyendetsa nthawi kupyolera mu msonkhano woyenera kuti zitsimikizire kulondola kwa njira yoyendetsera zipangizo.

4. Njira yolipirira yokwanira:

Gwiritsani ntchito zida zomwe zimayikidwa pa chochepetsera chokha kuti muwonetsetse kuti makinawo asinthidwa bwino ndikusinthidwa pa benchi yogwirira ntchito, kuti athetse zotsatira za zolakwika zosiyanasiyana zolondola.
