Ndedzipi mhando uye nzira dzekugadzirisa dze commutator yeDC mota?

Iyo commutator chikamu chakakosha cheiyo dc mota uye AC commutator armature. Iyo commutator inoshandisa simba kune yakakwana chinzvimbo pane rotor uye inogadzira yakagadzikana inotenderera simba (torque) nekudzoreredza kutungamira kwezvino mune armature inofamba coil yemota. Mumota, mudziyo unoshandura sikweya wave chiratidzo chinoyerwa neelectrode yekuyeresa kuita pulsating yakananga ikozvino nekudzoreredza gwara rezvino mumhepo inotenderera hafu yega yega nekuisa ino commutator kune inomonereka.

A commutator igadziriro yekudzivirira uye mitsetse yemhangura yakabatana kune coil yemota kuti ipe reverse ikozvino kune coil yemota. Commutation ndiko kudzoserwa kwegwara rezvino. Zvinoenderana neyekutenderera masitaera akasiyana uye akasiyana emukati ekiyi dhizaini yakakamurwa kuita yakakosha commutator uye ndege inofambisa ndege, yakakosha commutator ye cylindrical, copper strip parallel kune gomba, inoratidzirwa nechimiro chakareruka, kukwirira kwekugadzira. Integral commutators inowanikwa mumatatu ekutanga masitaera: mhangura uye mica, gore amai mold uye yakaumbwa dzimba. Iyo planar commutator inoita kunge fan ine tambo yemhangura ine fan fan perpendicular kune gomba.

Nekushandiswa kwepurasitiki mukati megomba uye shaft inotenderera, chimiro chiri nyore, asi saizi yegomba remukati mepurasitiki haisi nyore kubata, inofanirwa kudzora zvakanyanya saizi yekumanikidza kufa uye shrinkage yepurasitiki, kuitira kuve nechokwadi chekushivirira. yegomba regomba, inofanirwa kuyedza kudzivirira kudzvanywa kwepurasitiki kugadzirisa, kuita kwepurasitiki machining kunowanzo kuve kwakashata.

Sleeve yemhangura inomanikidzwa pamwe chete nepurasitiki, uye ukuru hwegomba re shaft iri nyore kuzadzisa zvinodiwa. Kuti udzivise kufamba pakati pepurasitiki uye sleeve, iyo yekunze denderedzwa pamusoro pesleeve inowanzovharwa kana kuputika. Iyo sleeve material inogona kuva yemhangura, simbi kana aluminium alloy. Asi zvinofanira kuonekwa kuti kuoma kwezvinhu kunofanira kufanana nekuoma kwe rotor shaft, zvishoma zvishoma kudarika kuoma kwe rotor shaft.

Mhete yekusimbisa inowedzerwa kune u-shaped groove ye commutator piece. Inowanzoshandiswa kutakura simba re centrifugal yemunda wemagetsi apo dhayamita ye commutator yakakamurwa uye kukwirira kunowedzera. Iko kuvharirwa pakati pemhete uye chidimbu che commutator kunofanirwa kuve nechokwadi. Nezvindori zvekuomesa, dhayamita ye commutator inogona kugadzirwa kusvika ku500.

Plane commutator

Muchokwadi, iyo zvakare yakaumbwa commutator, uye iyo mhangura yemhangura inosangana nebhurashi indege yemhete, chokwadi, inonzi commutator yendege, iyi commutator ine chimiro chakakosha, chiri papepa remhangura uye jira regraphite, basa rayo nderekutsiva kukweshera kweiyo commutator uye kabhoni brashi, kurebesa hupenyu hweiyo commutator.

Matatu marudzi e commutator processing

Kusangana kwakananga kweiyo commutator, saizi yemukombuta idiki, kazhinji inopinza chikamu chezasi cheshizha remhangura mucommutator muviri, wobva washandisa mhete yemhangura kudzvanya pepa remhangura pane yekunze denderedzwa pamusoro peiyo commutator, nekuti. iyo geometric saizi yechikamu idiki kwazvo, kugadzirwa kwemagetsi kwakaoma, kurongeka kweiyo commutator kunowanzo kuderera.

Iyo ndiro yemhangura yemukombuta ine hoko kumusoro uye maviri akatwasuka convex midzi anopinzwa mumuviri wecommutator zvichiteerana, kuitira kuti ndiro yemhangura yakanyatsobatanidzwa kune yekunze denderedzwa pamusoro peiyo commutator, uye ipapo ndiro yemhangura inogadziriswa. mabhagi maviri ezasi akatenderedzwa. Iyi commutator mukusandura huwandu hwekudya yakakurisa kuti igadzire pepa remhangura rinobhururuka risina kukwana, painotenderedzwa inofanirwa kudzora huwandu hwekudya mune imwe mhando. Kana zvichidikanwa, mamwe akawanda lathe maitiro anogona kushandiswa kuwana mhedzisiro inodiwa.

Mechanical yekubatanidza commutator, iyi inopatsanurwa commutator, mushure mekusangana kwezvikamu zvishanu, zvinowanzozivikanwa se "zvishanu mune chimwe", pamusoro pendiro yemhangura ine indent ring buckle, bhachi pane iyo convex commutator muviri, iyo yezasi chikamu invert buckle kupinda mucommutator support body, kune yekubatanidza commutator muviri uye inotsigira body. Mushure mekusvuura waya yependi yeganda, chidimbu chemhangura chemugadziri chinobatanidzwa newaya yeganda repende. Iyi commutator inoburitsawo zvimedu zvemhangura zvinobhururuka zvinorema kana huwandu hwekucheka hwakakurisa pakutendeuka.

mhedziso

Iyo commutator plate yakabatana nemakoiri eiyo armature. Huwandu hwemakoiri hunoenderana nekumhanya uye voltage yemota. Iyo brashi yemhangura inokodzera zvirinani kune yakaderera voltage uye yakakwira ikozvino, nepo kupikisa kwekabhoni brashi kuchikonzera kudonha kukuru kwevoltage. Copper's high conductivity zvinoreva kuti zvikamu zvinogona kuitwa zvidiki uye kuchengetwa padyo pamwechete. Kushandisa yakakandwa copper commutator inogona kuvandudza kushanda kwayo, yazvino inoyerera zviri nyore mumhangura, uye mota inowanzoita 85 kusvika 95 muzana inoshanda mukuendesa simba kumutoro wayo. Electronic commutation inoshandisa solid-state electronics pachinzvimbo chemagetsi ma commutators uye mabhurashi anoenderana, uye kubviswa kwemabhurashi kunoreva kushoma kukweshana kana kusakara pane system uye kunyatsoshanda. Aya marudzi emamota anowanzo kudhura uye akaomarara pane akareruka mabhurashi masisitimu nekuda kwekuda kwevatongi uye zvemagetsi.
