Yimuphi umshini wokunciphisa ongafakelwa imoto ye-stepper?

1. Isizathu sokuthi kungani imoto ye-stepper ifakwe i-reducer

Imvamisa yokushintsha i-stator phase current ku-stepper motor, njengokushintsha i-input pulse yesekethe ye-stepper motor drive ukuze ihambe ngesivinini esiphansi. Uma i-stepper motor enesivinini esiphansi ilinde umyalo we-stepper, i-rotor isesimweni sokuma. Uma inyathela ngesivinini esiphansi, ukushintshashintsha kwesivinini kuzoba kukhulu. Uma ishintshelwa ekusebenzeni ngesivinini esiphezulu, inkinga yokuguquguquka kwesivinini ingaxazululwa, kodwa i-torque ngeke yanele. Isivinini esiphansi sizobangela ukushintshashintsha kwe-torque, kuyilapho isivinini esikhulu sizobangela i-torque enganele, ngakho-ke kudingeka i-reducer.

 2. Yiziphi izinciphisi ezivame ukuhlonyiswa zama-stepper motors

I-reducer iyisakhi esizimele esakhiwe ngokudluliswa kwegiya, ukudluliswa kwe-worm, kanye nokudluliswa kwe-worm yegiya okuvalelwe egobolondweni eliqinile. Ivame ukusetshenziswa njengedivayisi yokudlulisa yokunciphisa phakathi kwe-drive yokuqala nomshini osebenzayo, idlala indima ekufaniseni isivinini kanye nokudlulisa i-torque phakathi kwe-drive yokuqala nomshini osebenzayo noma i-actuator;

Kunezinhlobo ezahlukene zama-reducer, angahlukaniswa ngama-gear reducers, ama-worm reducers, kanye nama-planetary gear reducers ngokuya ngohlobo lokudlulisela; Ngokwezigaba ezahlukene zokudlulisela, angahlukaniswa ngama-single-stage kanye nama-multi-stage reducers;

Ngokuya ngesimo samagiya, angahlukaniswa ngama-reducers egiya eliyindilinga, ama-reducers egiya le-bevel, kanye nama-reducers egiya eliyindilinga le-bevel;

Ngokwesakhiwo se-transmission, ingahlukaniswa ibe ama-reducer angavuleki, ama-split flow reducers, kanye nama-coaxial reducers.

Ama-reducer afakwe ama-stepper motors afaka phakathi ama-planetary reducers, ama-worm gear reducers, ama-parallel gear reducers, kanye nama-screw gear reducers.

Iyini ukunemba kwe-stepper motor planetary reducer?

Ukunemba kwe-reducer, eyaziwa nangokuthi i-return clearance, kutholakala ngokulungisa i-output end bese uyijikelezisa ngokwewashi nangokuphambene newashi ukuze kukhiqizwe i-torque elinganisiwe ye-+-2% torque ekugcineni kokuphuma. Uma kukhona i-angular displacement encane ekugcineni kokufakwa kwe-reducer, lokhu kushintsha kwe-angular kubizwa ngokuthi i-return clearance. Iyunithi "yi-arc minute", engama-degree angamashumi ayisithupha. Inani elijwayelekile le-return clearance libhekisela ekugcineni kokuphuma kwebhokisi legiya.

I-stepper motor planetary reducer inezici zokuqina okuphezulu, ukunemba okuphezulu (kufika kuphuzu eli-1 ngesigaba), ukusebenza kahle kokudlulisela okuphezulu (97% -98% ngesigaba), isilinganiso se-torque/volume ephezulu, futhi ayinayo i-maintenance.

Ukunemba kokudlulisela kwemoto ye-stepper akukwazi ukulungiswa, futhi i-engeli yokusebenza yemoto ye-stepper inqunywa ngokuphelele ubude besinyathelo kanye nenombolo ye-pulse. Inombolo ye-pulse ingabalwa ngokugcwele, futhi akukho mqondo wokunemba ngobuningi bedijithali. Isinyathelo esisodwa siyisinyathelo esisodwa, kanti isinyathelo sesibili siyizinyathelo ezimbili.

Ukunemba okwenziwe ngcono njengamanje ukunemba kokubuyiselwa kwegiya kwebhokisi legiya le-planetary reducer:

1. Indlela yokulungisa ukunemba kwe-spindle:

Ukulungiswa kokunemba kokujikeleza kwe-spindle ye-planetary reducer ngokuvamile kunqunywa yi-bearing uma iphutha lomshini we-spindle uqobo lihlangabezana nezidingo.

Isihluthulelo sokulungisa ukunemba kokujikeleza kwe-spindle ukulungisa indawo yokubeka izinsimbi. Ukugcina indawo yokubeka izinsimbi efanele kubalulekile ekusebenzeni nasekuphileni kwezinsimbi ze-spindle.

Kuma-rolling bearings, uma kunesikhala esikhulu, umthwalo ngeke nje ugxile entweni egoqayo lapho iqondiswa khona amandla, kodwa futhi uzobangela ukucindezeleka okukhulu lapho kuhlangana khona izindlela zangaphakathi nezangaphandle ze-bearings, kufinyeze impilo ye-bearings, futhi kushukumise umugqa ophakathi we-spindle, okulula ukubangela ukudlidliza kwezingxenye ze-spindle.

Ngakho-ke, ukulungiswa kwama-rolling bearings kumele kulayishwe kusengaphambili ukuze kukhiqizwe ukuphazamiseka okuthile ngaphakathi kwe-bearings, ngaleyo ndlela kukhiqizwe inani elithile lokuguquguquka okunwebekayo lapho kuxhumana khona phakathi kwento egoqayo kanye nemigwaqo yangaphakathi neyangaphandle, ngaleyo ndlela kuthuthukiswe ukuqina kwe-bearings.

2. Indlela yokulungisa igebe:

I-planetary reducer idala ukungqubuzana ngesikhathi sokunyakaza kwayo, okubangela ushintsho ngobukhulu, ukuma, kanye nekhwalithi yobuso bezingxenye, kanye nokuguguleka, okuholela ekwandeni kokulingana kwesikhala phakathi kwezingxenye. Ngalesi sikhathi, sidinga ukuyilungisa ngaphakathi kwebanga elifanele ukuqinisekisa ukunemba kokunyakaza okuhlobene phakathi kwezingxenye.

3. Indlela yokubuyisela amaphutha:

Umkhuba wokulungisa amaphutha ezingxenye ngokwazo ngesikhathi sokusebenza ngesikhathi sokuhlanganiswa okufanele ukuqinisekisa ukunemba komzila wokunyakaza kwemishini.

4. Indlela ephelele yesinxephezelo:

Sebenzisa amathuluzi afakwe ku-reducer uqobo ukuqinisekisa ukuthi imishini ilungiswe kahle futhi yalungiswa ebhentshini lokusebenza, ukuze kuqedwe imiphumela ephelele yamaphutha ahlukahlukene okunemba.
