Mabheyaringi ndiwo anonyanya kutsigira mota. Mumamiriro ezvinhu akajairwa, kana tembiricha yemabheyaringi emota ikadarika 95°C uye tembiricha yemabheyaringi anotsvedza ikadarika 80°C, mabheyaringi anopiswa zvakanyanya.
Kupisa zvakanyanya kana mota ichishanda idambudziko rakajairika, uye zvikonzero zvacho zvakasiyana-siyana, uye dzimwe nguva zvakaoma kuona nemazvo, saka muzviitiko zvakawanda, kana kurapwa kusingaitwe nenguva, mhedzisiro yacho inowanzo kuvadza mota, zvichiita kuti mota igare kwenguva pfupi, izvo zvinokanganisa basa nekugadzirwa. Pfupikisa mamiriro chaiwo, zvikonzero uye nzira dzekurapa kupisa kwakanyanya kwemotokari.
1. Zvikonzero uye nzira dzekurapa kupisa mabheyaringi emota:
1. Bearing inotenderera yakaiswa zvisirizvo, kushivirira kwayo kwakasimba zvakanyanya kana kuti kwakasununguka zvakanyanya.
Mhinduro: Kushanda kwema rolling bearings hakungotsamiri pakugadzirwa kwakarurama kwebearings pachadzo, asiwo pakururama kwedivi, kushivirira chimiro uye kuomarara kwemubato neburi zvinoenderana nawo, kukodzera kwakasarudzwa uye kana kuiswa kwacho kwakarurama kana kwete.
Mumamota akatarwa, mabheya ekufambisa akagadzirwa zvakanaka anongotakura radial stress, asi kana kupindirana pakati pemhete yemukati yebheya neshaft kwakanyanya kusimba, kana kupindirana pakati pemhete yekunze yebheya nekuvhara kwekupedzisira kwakanyanya kusimba, ndiko kuti, kana kushivirira kwakanyanya, ipapo mushure mekuunganidza nzvimbo yebheya ichave diki zvakanyanya, dzimwe nguva kutosvika pazero. Kutenderera hakuchinjiki seizvi, uye kuchaita kuti pave nekupisa panguva yekushanda.
Kana kupindirana pakati pemhete yemukati yebearing neshaft kwakasununguka zvakanyanya, kana kuti mhete yekunze yebearing necover yekupedzisira zvakasununguka zvakanyanya, ipapo mhete yemukati yebearing neshaft, kana mhete yekunze yebearing necover yekupedzisira, zvinotenderera zvichienderana, zvichikonzera kukweshana nekupisa, zvichikonzera kutadza kwebearing. Kazhinji, nzvimbo yekutsungirira yedhayamita yemukati yebearing inner ring sechikamu chereferensi inotamiswa pasi pemutsetse we zero mu standard, uye nzvimbo yekutsungirira yeshaft imwechete nering yemukati yebearing inoita kupindirana kwakasimba kupfuura kwakaumbwa neburi rereferensi.
2. Kusasarudzwa kwakakodzera kwemafuta anozora kana kushandiswa nekugadziriswa zvisina kunaka, mafuta anozora asina kunaka kana akaora, kana kusanganiswa neguruva netsvina zvinogona kukonzera kupisa kwebearing.
Mhinduro: Kuwedzera mafuta akawandisa kana mashoma kuchaitawo kuti bearing ipise, nekuti kana paine mafuta akawandisa, pachava nekukakavadzana kukuru pakati pechikamu chinotenderera chebearing nemafuta, uye kana mafuta akawedzerwa mashoma, kuoma kunogona kuitika. Kukakavadzana nekupisa. Nokudaro, huwandu hwemafuta hunofanira kugadziriswa kuitira kuti huve 1/2-2/3 yehuwandu hwenzvimbo yebearing chamber. Mafuta akawandisa kana akaora anofanira kucheneswa uye kutsiviwa nemafuta akachena akakodzera.
3. Mukana wepakati pakati pechifukidziro chekunze chemotokari nedenderedzwa rekunze rebheyaringi rinotenderera idiki kwazvo.
Mhinduro: Mota hombe nedzepakati dzinoshandisa mabhora ekufambisa panzvimbo isina shaft. Mabhora ekufambisa anoshandiswa pamagumo ekuwedzera kweshaft, kuitira kuti kana rotor yapiswa uye yakawedzerwa, ikwanise kurebesa zvakasununguka. Sezvo magumo ese emota diki achishandisa mabhora ekufambisa, panofanira kuva nemukana wakakodzera pakati pechifukidziro chekunze chekutakura nemhete yekunze yekutakura, zvikasadaro, bearing inogona kupisa nekuda kwekureba kwakanyanya kwekupisa munzira yeaxial. Kana chiitiko ichi chikaitika, chifukidziro chemberi kana chekumashure chekutakura chinofanira kubviswa zvishoma, kana kuti pepa rakatetepa rinofanira kuiswa pakati pechifukidziro chekutakura nemhete yekupedzisira, kuitira kuti pave nenzvimbo yakakwana pakati pechifukidziro chekunze chekutakura kune rimwe divi nemhete yekunze yekutakura. Kuchenesa.
4. Zvivharo zvekupedzisira kana mabheyaringi kumativi ese emota hazvina kuiswa zvakanaka.
Mhinduro: Kana mavharo ekupedzisira kana mavharo ebheyaringi kumativi ese emota asina kuiswa zvakaenzana kana kuti misono isina kusimba, mabhora anotsauka kubva panzira otenderera kuti abudise kupisa. Mavharo ekupedzisira kana mavharo ebheyaringi kumativi ese anofanira kudzoserwa zvakare akati sandara, uye kutenderedzwa zvakaenzana uye kugadziriswa nemabhoti.
5. Mabhora, maroller, mhete dzemukati nedzekunze, uye mabhokisi ebhora zvakasakara zvakanyanya kana kuti simbi iri kubviswa.
Mhinduro: Bearing inofanira kutsiviwa panguva ino.
6. Kusabatana zvakanaka nemichina yekutakura zvinhu.
Zvikonzero zvikuru ndeizvi: kusabatana zvakanaka kwekubatanidza, kudhonzwa kwakanyanya kwebhandi, kusawirirana ne axis yemuchina wekutakura, dhayamita diki kwazvo yepulley, kure zvakanyanya ne bearing yepulley, mutoro wakawandisa we axial kana radial, nezvimwewo.
Mhinduro: Gadzirisa kubatana kusina kunaka kudzivirira simba risingawanzoitiki pabheyaringi.
7. Mubato wacho wakakombama.
Mhinduro: Panguva ino, simba riri pabearing harisisiri simba re radial chete, izvo zvinoita kuti bearing ripise. Edza kururamisa shaft yakakombama kana kuitsiva nebearing itsva.
2. Nzira yekudzivirira sei injini kubva pakupisa zvakanyanya?
Inogona kufungwa nezvekuviga chinhu chinoyera tembiricha pedyo nebearing, uye yobva yadzivirira bearing kuburikidza ne control circuit. Kazhinji, mota ine chinhu chinoyera tembiricha (senge thermistor) mukati memota, uye waya mbiri dzinobuda kubva mukati kuti dzibatane nemudziviriri wakakosha, uye mudziviriri anotumira voltage ye24V isingachinji, kana bearing yemota ikapfuura kukosha kwakatemwa kwemudziviriri, inogumburwa uye inoita basa rekudzivirira. Parizvino, vagadziri vazhinji vemota munyika vanoshandisa nzira iyi yekudzivirira.
