Yeyiphi i-reducer enokuthi ixhotyiswe nge-stepper motor?

1. Isizathu sokuba kutheni i-motor stepper ixhotyiswe nge-reducer

Ubuninzi bokutshintsha kwesigaba se-stator yangoku kwi-motor stepper, njengokutshintsha i-pulse yegalelo le-stepper motor drive circuit ukuze ihambe ngesantya esiphantsi. Xa i-motor-speed stepper motor ilindele umyalelo we-stepper, i-rotor ikwimeko yokumisa. Xa unyathela ngesantya esiphantsi, ukuguquguquka kwesantya kuya kubaluleka. Ukuba itshintshiwe ekusebenzeni kwesantya esiphezulu, ingxaki yokuguquguquka kwesantya ingasombululwa, kodwa i-torque ayiyi kukwanela. Isantya esisezantsi siya kubangela ukuguquguquka kwe-torque, ngelixa isantya esiphezulu siya kubangela i-torque eyaneleyo, ngoko ke kufuneka i-reducers.

 2. Zeziphi ii-reducers eziqhelekileyo ezixhotyiswe kwii-motor stepper

Isinciphisi licandelo elizimeleyo elenziwe kuthumelo lwegiya, usasazo lweentshulube, kunye nokuhanjiswa kweentshulube ezifakwe kwiqokobhe eliqinileyo. Ngokuqhelekileyo isetyenziswe njengesixhobo sokunciphisa ukuhanjiswa phakathi kwe-original drive kunye nomatshini osebenzayo, idlala indima ekufaniseni isantya kunye nokudlulisa i-torque phakathi kwe-original drive kunye nomatshini osebenzayo okanye i-actuator;

Kukho iintlobo ezahlukeneyo zokunciphisa, ezinokwahlulwa zibe zinciphisi zegiya, izinciphisi zeentshulube, kunye nezinciphisi zegiya zeplanethi ngokohlobo lothumelo; Ngokwezigaba ezahlukeneyo zothumelo, inokwahlulwa ibe yinqanaba elinye kunye namanqanaba amaninzi;

Ngokwemilo yeegiya, zinokwahlulwa zibe zinciphisi zegiya zesilinda, izinciphisi zegiya ze-bevel, kunye nezinciphisi zegiya ze-bevel cylindrical;

Ngokwendlela yokuhanjiswa, inokwahlulwa ibe zinciphisi ezingasombulukanga, izinciphisi zokuqukuqela ezahlulahlula, kunye nezinciphisi ze-coaxial.

Abanciphisi baxhotyiswe ngeenjini ze-stepper ziquka izinciphisi zeplanethi, izinciphisi zegiya zeentshulube, izinciphisi zegiya ezinxuseneyo, kunye nezinciphisi zegiya ezijijwayo.

Yintoni ukuchaneka kwesinciphisi seplanethi ye-stepper motor?

Ukuchaneka kwe-reducer, eyaziwa ngokuba yi-return clearance, iphunyezwa ngokulungisa isiphelo somphumo kunye nokujikeleza i-clockwise kunye ne-counterclockwise ukuvelisa i-torque elinganisiweyo ye-+ -2% torque ekupheleni kokuphuma. Xa kukho ukufuduswa kwe-angular encinci ekupheleni kwegalelo lesinciphisi, oku kushenxiswa kwe-angular kubizwa ngokuba yi-return clearance. Iyunithi “yi-arc minute”, eyinxalenye yamashumi amathandathu edigri. Ixabiso eliqhelekileyo lokubuyiswa kwembuyekezo libhekiselele ekupheleni kwemveliso yebhokisi yegiya.

I-stepper motor planetary reducer ineempawu zokuqina okuphezulu, ukuchaneka okuphezulu (ukuya kwi-1 iphuzu kwinqanaba ngalinye), ukuhanjiswa okuphezulu (97% -98% kwinqanaba ngalinye), umlinganiselo ophezulu we-torque / umthamo, kunye nokugcinwa kwamahhala.

Ukuchaneka kokuhanjiswa kwemoto ye-stepper ayinakulungiswa, kwaye i-angle yokusebenza ye-motor stepper igqitywe ngokupheleleyo ubude besinyathelo kunye nenombolo ye-pulse. Inombolo ye-pulse ingabalwa ngokupheleleyo, kwaye akukho ngcamango yokuchaneka kumanani edijithali. Inyathelo elinye linyathelo elinye, kwaye elesibini ngamanyathelo amabini.

Ukuchaneka okulungiselelwe ngoku kukuchaneka kokubuyiselwa kwegiya kwibhokisi yegiya yokunciphisa iplanethi:

1. Indlela yokulungelelanisa ukuchaneka kwe-spindle:

Ukulungelelaniswa kokuchaneka kokujikeleza kweplanethi yokunciphisa i-spindle ngokuqhelekileyo kunqunywe ngokuthwala ukuba impazamo yomatshini we-spindle ngokwayo ihlangabezana neemfuno.

Isitshixo sokulungelelanisa ukuchaneka kokujikeleza kwe-spindle kukulungelelanisa ukuchithwa kwe-bearing clearance. Ukugcina ucoceko olufanelekileyo lubalulekile ekusebenzeni nasekuthwaleni ubomi bamalungu e-spindle.

Kwiibheringi eziqengqelekayo, xa kukho umsantsa omkhulu, umthwalo awuyi kugxila kuphela kwinto eqengqelekayo kwicala lamandla, kodwa kuya kubangela uxinzelelo olukhulu kunxibelelwano phakathi kweendlela zangaphakathi nangaphandle zogqatso, mfutshane ukuthwala ubomi, kunye nokukhukuliseka kumgca osembindini we-spindle, ekulula ukubangela ukungcangcazela kwamalungu e-spindle.

Ke ngoko, uhlengahlengiso lweebheringi eziqengqelekayo kufuneka zilayishwe kwangaphambili ukuvelisa isixa esithile sokuphazamiseka ngaphakathi kwibheringi, ngaloo ndlela kuvelisa umlinganiselo othile we-elastic deformation kuqhagamshelwano phakathi kwento eqengqelekayo kunye ne-raceways yangaphakathi nangaphandle, ngaloo ndlela kuphuculwe ukuqina kokuthwala. .

2. Indlela yokulungelelanisa isithuba:

Isinciphisi seplanethi sivelisa ukungqubuzana ngexesha lokuhamba kwayo, okubangela utshintsho kubukhulu, imilo, kunye nomgangatho ophezulu wamalungu, kunye nokuguga kunye nokukrazula, okubangela ukwanda kwe-clearance fit phakathi kwamalungu. Ngeli xesha, kufuneka siyilungelelanise phakathi koluhlu olufanelekileyo ukuqinisekisa ukuchaneka kwentshukumo ehambelanayo phakathi kwamalungu.

3. Indlela yembuyekezo yempazamo:

Isenzeko sokuphelisa iimpazamo zamalungu ngokwawo ngexesha lokuqhuba ngokwendibano efanelekileyo ukuze kuqinisekiswe ukuchaneka kwendlela yokuhamba kwesixhobo.

4. Indlela yembuyekezo ebanzi:

Sebenzisa izixhobo ezifakwe kwi-miniderer ngokwayo ukuqinisekisa ukuba umatshini ulungelelaniswe ngokuchanekileyo kwaye ulungelelaniswe kwi-workbench, ukwenzela ukuphelisa umphumo obanzi weempazamo ezahlukeneyo ezichanekileyo.
