Ma bearings ndi mbali zofunika kwambiri zothandizira ma motors.Muzochitika zachilendo, pamene kutentha kwa mayendedwe a galimoto kumapitirira 95 ° C ndipo kutentha kwa zitsulo zotsetsereka kumapitirira 80 ° C, mayendedwe amatenthedwa.
Kukhala ndi kutenthedwa kwamoto pamene galimoto ikuyenda ndi vuto wamba, ndipo zifukwa zake zimakhala zosiyanasiyana, ndipo nthawi zina zimakhala zovuta kuzizindikira molondola, choncho nthawi zambiri, ngati chithandizo sichili panthawi yake, zotsatira zake nthawi zambiri zimakhala zowonongeka kwambiri kwa galimotoyo, kupanga. injini Kutalika kwa moyo kumafupikitsidwa, zomwe zimakhudza ntchito ndi kupanga.Fotokozerani mwachidule zochitika zenizeni, zifukwa ndi njira zamankhwala zamagalimoto onyamula kutenthedwa.
1. Zifukwa ndi njira zochizira kutenthedwa kwa mayendedwe agalimoto:
1. Kutulutsa kozungulira kumayikidwa molakwika, kulekerera koyenera kumakhala kolimba kwambiri kapena kotayirira.
Yankho: Kugwira ntchito kwa mayendedwe ogubuduza kumadalira osati pakupanga kulondola kwa chotengeracho chokha, komanso kulondola kwazithunzi, kulolerana kwa mawonekedwe ndi kuuma kwapamwamba kwa tsinde ndi dzenje zomwe zikugwirizana nazo, zoyenera zosankhidwa komanso ngati kukhazikitsidwa kuli kolondola. kapena osati.
Nthawi zambiri ma mota opingasa, ma fani ogubuduza opangidwa bwino amangokhala ndi kupsinjika kwa radial, koma ngati kukwanira pakati pa mphete yamkati ndi shaft ndi yolimba kwambiri, kapena kukwanirana pakati pa mphete yakunja ndi chivundikiro chomaliza kumakhala kolimba kwambiri. , ndiko kuti, pamene kulekerera kuli kwakukulu, ndiye pambuyo pa msonkhano Chilolezo chonyamula chidzakhala chochepa kwambiri, nthawi zina ngakhale pafupi ndi zero.Kuzungulirako sikusinthika motere, ndipo kumatulutsa kutentha panthawi yogwira ntchito.
Ngati kugwirizana pakati pa mphete yamkati ndi shaft ndi yotayirira kwambiri, kapena mphete yonyamulira ndi chivundikiro chakumapeto ndizotayirira kwambiri, mphete yamkati ndi shaft, mphete yakunja ndi chivundikiro chakumapeto zimayenda mozungulira. kwa wina ndi mzake, zomwe zimachititsa kukangana ndi kutentha, kumabweretsa kulephera.kutentha kwambiri.Nthawi zambiri, malo olekerera amkati mwa mphete yamkati yonyamula ngati gawo lolozera amasunthidwa pansi pa mzere wa zero mu muyezo, ndipo gawo lololera la shaft lomwelo ndi mphete yamkati yamkati mwake imakhala yolimba kwambiri. kuposa yomwe idapangidwa ndi bowo lazofotokozera.
2. Kusankhidwa molakwika kwa mafuta opaka mafuta kapena kugwiritsa ntchito molakwika ndi kukonza bwino, mafuta opaka mafuta osakwanira kapena owonongeka, kapena osakanizidwa ndi fumbi ndi zonyansa kungayambitse kutentha.
Yankho: Kuonjezera mafuta ochulukirapo kapena ochepa kwambiri kumapangitsanso kutentha, chifukwa mafuta akakhala ochuluka, pamakhala kukangana kwakukulu pakati pa gawo lozungulira la thumba ndi girisi, komanso pamene mafuta awonjezeredwa. pang'ono, kuuma kungachitike Kukangana ndi kutentha.Chifukwa chake, kuchuluka kwamafuta kuyenera kusinthidwa kuti ikhale pafupifupi 1/2-2/3 ya danga la chipinda chonyamula.Mafuta opaka osayenera kapena owonongeka ayenera kutsukidwa ndi kusinthidwa ndi mafuta oyenera aukhondo abwino.
3. Mpata wa axial pakati pa chivundikiro chakunja cha mota ndi bwalo lakunja la chonyamulira ndi chochepa kwambiri.
Yankho: Ma motors akulu ndi apakatikati nthawi zambiri amagwiritsa ntchito mayendedwe a mpira kumapeto komwe sikuli shaft.Zovala zodzigudubuza zimagwiritsidwa ntchito kumapeto kwa kufalikira kwa shaft, kotero kuti pamene rotor yatenthedwa ndi kukulitsidwa, imatha kufalikira momasuka.Popeza malekezero onse a injini yaying'ono amagwiritsa ntchito mpira, payenera kukhala kusiyana koyenera pakati pa chivundikiro chakunja ndi mphete yakunja ya chonyamulira, apo ayi, kunyamula kumatha kutenthedwa chifukwa cha kuchuluka kwamafuta ochulukirapo munjira ya axial.Chodabwitsa ichi chikachitika, kutsogolo kapena kumbuyo kumbuyo kumayenera kuchotsedwa pang'ono, kapena pepala laling'ono la pepala liyenera kuikidwa pakati pa chivundikirocho ndi chivundikiro chomaliza, kuti malo okwanira apangidwe pakati pa chivundikiro chakunja chakunja pamapeto pake. ndi mphete yakunja ya chimbalangondo.Chilolezo.
4. Zophimba zomaliza kapena zipewa zonyamula mbali zonse za injini sizimayikidwa bwino.
Yankho: Ngati chivundikiro chomaliza kapena zotchingira mbali zonse ziwiri za galimotoyo sichinakhazikitsidwe mofanana kapena zomangira sizili zolimba, mipirayo imachoka panjanji ndikuzungulira kuti ipangitse kutentha.Zipewa kapena zipewa zonyamula mbali zonse ziwiri ziyenera kubwezeretsedwanso mosabisa, ndikuzunguliridwa mozungulira ndikukhazikika ndi mabawuti.
5. Mipira, zodzigudubuza, mphete zamkati ndi zakunja, ndi makola a mpira amavalidwa kwambiri kapena kusenda chitsulo.
Yankho: Chotengeracho chiyenera kusinthidwa panthawiyi.
6. Kusalumikizana bwino kwa makina onyamula.
Zifukwa zazikulu ndi izi: kusonkhana kosauka kwa kugwirizana, kukoka kwakukulu kwa lamba, kusagwirizana ndi nsonga ya makina onyamula katundu, m'mimba mwake kakang'ono kwambiri ka pulley, kutali kwambiri ndi kukwera kwa pulley, axial kapena radial katundu wambiri, etc. .
Yankho: Konzani kulumikizana kolakwika kuti mupewe mphamvu yachilendo pamayendedwe.
7. Mtsinje wapindika.
Yankho: Panthawiyi, mphamvu yonyamula sichikhalanso mphamvu yoyera ya radial, yomwe imayambitsa kutentha.Yesani kuwongola tsinde lopindika kapena m'malo mwake ndi chotengera chatsopano
2. Momwe mungatetezere chotengera chamoto kuti chisatenthedwe?
Itha kuganiziridwa kuti imakwirira chinthu choyezera kutentha pafupi ndi kunyamula, ndikuteteza kunyamula kudzera mumayendedwe owongolera.Koperani Nthawi zambiri, galimotoyo imakhala ndi chinthu choyezera kutentha (monga thermistor) mkati mwa injini, ndiyeno mawaya awiri amatuluka mkati kuti agwirizane ndi chitetezo chapadera, ndipo wotetezera amatumiza voteji ya 24V nthawi zonse, pamene galimotoyo imanyamula Pamene kutenthedwa kupitirira mtengo woikidwiratu wa chitetezo, chidzayenda ndikugwira ntchito yoteteza.Pakadali pano, opanga magalimoto ambiri mdziko muno amagwiritsa ntchito njira yodzitetezera.
