Yeyiphi i-reducer enokuxhotyiswa nge-stepper motor?

1. Isizathu sokuba imoto ye-stepper ifakwe i-reducer

Ubuninzi bokutshintsha i-stator phase current kwi-stepper motor, njengokutshintsha i-input pulse yesekethe ye-stepper motor drive ukuze ihambe ngesantya esiphantsi. Xa i-stepper motor enesantya esiphantsi ilinde umyalelo we-stepper, i-rotor ikwimeko yokuma. Xa inyathela ngesantya esiphantsi, ukuguquguquka kwesantya kuya kuba mkhulu. Ukuba itshintshelwe ekusebenzeni ngesantya esiphezulu, ingxaki yokuguquguquka kwesantya ingasombululwa, kodwa i-torque ayizukwanela. Isantya esiphantsi siya kubangela ukuguquguquka kwe-torque, ngelixa isantya esiphezulu siya kubangela ukuguquguquka kwe-torque enganeleyo, ngoko ke kufuneka i-reducer.

 2. Zeziphi izixhobo zokunciphisa ezixhaphakileyo zeemoto ze-stepper

I-reducer yinxalenye ezimeleyo eyenziwe yi-gear transmission, i-worm transmission, kunye ne-gear worm transmission evalelwe kwiqokobhe eliqinileyo. Isetyenziswa njengesixhobo sokunciphisa i-reduction transmission phakathi kwe-original drive kunye nomatshini osebenzayo, idlala indima ekuhambelaniseni isantya kunye nokudlulisa i-torque phakathi kwe-original drive kunye nomatshini osebenzayo okanye i-actuator;

Kukho iintlobo ngeentlobo zee-reducers, ezinokwahlulwa zibe zii-gear reducers, ii-worm reducers, kunye nee-planetary gear reducers ngokwe-transmission type; Ngokwezigaba ezahlukeneyo ze-transmission, inokwahlulwa ibe zii-single-stage kunye nee-multi-stage reducers;

Ngokwemilo yeegiya, zingahlulwa zibe zii-cylindrical gear reducers, bevel gear reducers, kunye ne-bevel cylindrical gear reducers;

Ngokwendlela olubekwe ngayo uthumelo, lungahlulwahlulwa lube zii-unfolded reducers, ii-split flow reducers, kunye nee-coaxial reducers.

Ezi zinciphisi zixhotyiswe ngeemoto ze-stepper ziquka izinciphisi zeplanethi, izinciphisi zegiya le-worm, izinciphisi zegiya ezihambelanayo, kunye nezinciphisi zegiya ezijijekileyo.

Ithini indlela echanekileyo ngayo i-stepper motor planetary reducer?

Ukuchaneka kwe-reducer, okwaziwa ngokuba yi-return clearance, kufezekiswa ngokulungisa isiphelo se-output kunye nokusijikelezisa ngokwewotshi nangokuchasene newotshi ukuze kuveliswe i-torque elinganisiweyo ye-+-2% torque kwisiphelo se-output. Xa kukho i-angular displacement encinci kwisiphelo se-input se-reducer, le-angular displacement ibizwa ngokuba yi-return clearance. Iyunithi yi-"arc minute", eyi-1/60 ye-degree. Ixabiso eliqhelekileyo le-return clearance libhekisa kwisiphelo se-output se-gearbox.

I-stepper motor planetary reducer ineempawu zokuqina okuphezulu, ukuchaneka okuphezulu (ukuya kuthi ga kwi-1 point ngesigaba), ukusebenza kakuhle kokudlulisa (97% -98% ngesigaba), umlinganiselo ophezulu we-torque/volume, kwaye ayinayo i-maintenance.

Ukuchaneka kokudluliselwa kwemoto ye-stepper akunakulungiswa, kwaye i-engile yokusebenza kwemoto ye-stepper imiselwa ngokupheleleyo bubude benyathelo kunye nenombolo ye-pulse. Inombolo ye-pulse ingabalwa ngokupheleleyo, kwaye akukho ngcamango yokuchaneka kwinani ledijithali. Inyathelo elinye linyathelo elinye, kwaye inyathelo lesibini linyathelo ezimbini.

Ukuchaneka okwenziwe ngcono okwangoku kukuchaneka kokubuyiselwa kwegiya kwebhokisi yegiya yokunciphisa iplanethi:

1. Indlela yokulungisa ukuchaneka kwe-spindle:

Ukulungiswa kokuchaneka kokujikeleza kwe-spindle ye-planetary reducer ngokuqhelekileyo kugqitywa yi-bearing ukuba impazamo yokwenziwa kwe-spindle ngokwayo iyahlangabezana neemfuno.

Eyona nto ibalulekileyo ekulungiseni ukuchaneka kokujikeleza kwe-spindle kukulungisa indawo evulekileyo ye-bearing. Ukugcina indawo efanelekileyo ye-bearing kubalulekile ekusebenzeni nasekuphileni ubomi be-bearing bezinto ze-spindle.

Kwi-rolling bearings, xa kukho umsantsa omkhulu, umthwalo awuyi kugxila kuphela kwi-rolling element kwicala lamandla, kodwa uya kubangela uxinzelelo olukhulu xa kudityaniswe iindlela zangaphakathi nezangaphandle ze-bearing, unciphise ubomi be-bearing, kwaye ushukumise umgca ophakathi we-spindle, okulula ukubangela ukungcangcazela kwezixhobo ze-spindle.

Ke ngoko, ukulungiswa kwee-rolling bearings kufuneka kulayishwe kwangaphambili ukuze kuveliswe uphazamiseko oluthile ngaphakathi kwe-bearings, ngaloo ndlela kuveliswe ubuninzi bokuguquguquka kwe-elastic ekudibaneni phakathi kwe-rolling element kunye neendlela zangaphakathi nezangaphandle, ngaloo ndlela kuphuculwe ukuqina kwe-bearings.

2. Indlela yokulungisa isithuba:

I-planetary reducer idala ukungqubana ngexesha lokuhamba kwayo, nto leyo ebangela utshintsho kubungakanani, imo, kunye nomgangatho womphezulu wamalungu, kunye nokuguguleka, nto leyo ebangela ukwanda kokulingana phakathi kwamalungu. Ngeli xesha, kufuneka siyilungise kuluhlu olufanelekileyo ukuqinisekisa ukuchaneka kwentshukumo phakathi kwamalungu.

3. Indlela yokulungisa iimpazamo:

Ingxaki yokulungisa iimpazamo zamalungu ngokwawo ngexesha lokusebenza ngexesha lokuhlanganiswa okufanelekileyo ukuqinisekisa ukuchaneka kwendlela yokuhamba kwesixhobo.

4. Indlela ebanzi yokuhlawula:

Sebenzisa izixhobo ezifakwe kwi-reducer ngokwayo ukuqinisekisa ukuba i-machining ilungiswe ngokuchanekileyo kwaye ilungiswe kwi-workbench, ukuze kupheliswe iziphumo ezipheleleyo zeempazamo ezahlukeneyo zokuchaneka.
