Zvikonzero uye nzira dzekurapa dzemota inotakura overheating

Bearings ndiwo akakosha anotsigira zvikamu zvemotor.Mumamiriro ezvinhu akajairika, apo kutonhora kwemagetsi emotokari kunodarika 95 ° C uye kutonhora kwezvipfeko zvinotsvedza zvinodarika 80 ° C, mabheji anopisa.

Kutakura kupisa kana injini ichimhanya imhosva yakajairika, uye zvikonzero zvayo zvakasiyana, uye dzimwe nguva zvakaoma kunyatsoongorora, saka muzviitiko zvakawanda, kana kurapwa kusiri panguva yakakodzera, mhedzisiro inowanzowedzera kukuvadza kune mota, zvichiita. iyo mota Nguva yehupenyu inopfupikiswa, iyo inokanganisa basa nekugadzirwa.Pfupisa iyo chaiyo mamiriro, zvikonzero uye nzira dzekurapa dzemota inotakura overheating.

1. Zvikonzero uye nzira dzekurapa dzekuwedzeredza kwemabhengi emota:

1. Iyo rolling bearing yakaiswa zvisizvo, iyo fit tolerance yakanyanya kusimba kana yakasununguka.

Kugadzirisa: Kushanda kwekushanda kwemabheji ekutenderera kunoenderana kwete chete nekugadzirwa kweiyo kubereka kwayo pachayo, asiwo pakurongeka kwedimensional, kushivirira kwechimiro uye hutsinye hwepamusoro hwe shaft uye gomba rinoenderana naro, iyo yakasarudzwa yakakodzera uye kana kuiswa kwacho kwakarurama. kana kuti kwete.

Muzhinji mamotor akatwasuka, akanyatso kuunganidzwa anotenderedza mabearings anongotakura radial stress, asi kana kukwana pakati pemhete yemukati yeberengi uye shaft yakanyanya kusimba, kana kukwana pakati pemhete yebere uye chivharo chekupedzisira chakanyanya kusimba. , ndiko kuti, kana kushivirira kwakanyanyisa, ipapo mushure megungano Kubvumirwa kwekutakura kuchava kuduku, dzimwe nguva kunyange pedyo ne zero.Iko kutenderera hakuchinjiki seizvi, uye kunoburitsa kupisa panguva yekushanda.

Kana kukwana pakati perin'i yemukati neshaft yanyanya kunyanyorembera, kana rin'i yekunze nevhavha yakanyanyorembera, ipapo rin'i yemukati inotakura neshaft, kana mhete yekunze nechivharo chekupedzisira, zvinotenderedza hama. kune mumwe nomumwe, zvichiita kupesana uye kupisa, zvichiguma nokukundikana.overheat.Kazhinji, iyo yekushivirira nzvimbo yemukati dhayamita yeinotakura yemukati mhete sereferenzi chikamu chinofambiswa pazasi pe zero mutsara muyero, uye iyo yekushivirira nzvimbo yeiyo shaft imwechete uye mhete yemukati yeinotakura inoumba yakakodzera iyo yakanyanya kusimba. kupfuura iyo yakaumbwa nehole yereferensi .

2. Kusarudzwa kusina kukodzera kwemafuta ekuzora kana kushandiswa kusina kunaka nekugadzirisa, kusina kunaka kana kuparara kwemafuta ekuzora, kana kusanganiswa neguruva uye tsvina zvinogona kukonzera kutakura kupisa.

Kugadzirisa: Kuwedzera girizi yakawandisa kana kushoma kuchaitawo kuti giresi ridziye, nekuti kana girizi yakawandisa, panove nekukweshana kwakawanda pakati pechikamu chinotenderera chebere uye girizi, uye kana girisi yawedzerwa. kushoma kwazvo, kuoma kunogona kuitika Friction uye kupisa.Naizvozvo, huwandu hwegirisi hunofanirwa kugadziridzwa kuitira kuti ive inenge 1/2-2/3 yenzvimbo vhoriyamu yekamuri yekubereka.Mafuta ekuzora asina kukodzera kana kuti akaora anofanira kucheneswa uye kutsiviwa negirisi yekuzora yakachena.

3. Iyo axial gap pakati pekunze kwekuvhara chivharo chemota uye denderedzwa rekunze rekukungurutsira idiki.

Solution: Mahombe uye epakati-saizi mota anowanzo shandisa bhora mabhengi kumagumo asiri-shaft.Roller bearings inoshandiswa pamagumo ekuwedzera kwe shaft, kuitira kuti kana rotor ichipisa uye ichiwedzerwa, inogona kureba zvakasununguka.Sezvo migumo miviri yeinjini diki inoshandisa bhora mabhengi, panofanirwa kunge paine gaka rakakodzera pakati pechifukidziro chekunze chekutakura uye mhete yekunze yekutakura, kana zvisina kudaro, kutakura kunogona kupisa nekuda kwekuwedzeredza kwemafuta elongation munzira yeaxial.Kana chiitiko ichi chikaitika, chifukidziro chemberi kana cheshure chinofanira kubviswa zvishoma, kana pepa rakatetepa rinofanira kuiswa pakati pechifukidziro chekutakura uye chivharo chekupedzisira, kuitira kuti nzvimbo yakakwana iumbwe pakati pechifukidziro chekunze kune imwe mugumo. nechindori chokunze chefaniro.Clearance.

4. Mhedziso inovhara kana kutakura zvivharo kumativi ose emotokari hazvina kuiswa zvakanaka.

Kugadzirisa: Kana iyo yekupedzisira yakavhara kana kutakura zvivharo pamativi ese emota zvisina kuiswa mukufanana kana seams asina kusimba, mabhora anotsauka kubva panjanji uye anotenderera kuti abudise kupisa.Iyo yekupedzisira caps kana inotakura caps pamativi ese ari maviri inofanirwa kudzoserwa sandara, uye yakaenzana kutenderedzwa uye kugadziriswa nemabhaudhi.

5. Mabhora, ma<em>rollers, marin’i emukati neokunze, uye makeji ebhora zvakasakara zvakakomba kana kuti simbi inosvuuka.

Mhinduro: Kutakura kunofanira kuchinjwa panguva ino.

6. Kusabatana kwakashata kurongedza michina.

Zvikonzero zvikuru ndezvi: kusangana kwakashata kwekubatanidza, kudhonza kwakanyanya kwebhandi, kusapindirana neakisi yemuchina wekutakura, dhayamita diki yepulley, kure kure nekutakurwa kwepulley, yakawandisa axial kana radial mutoro, nezvimwe, nezvimwe. .

Kugadzirisa: Gadzirisa kubatana kusiri iko kudzivirira simba risiri iro pabearing.

7. Shaft yakakotama.

Solution: Panguva ino, simba riri pakutakura harisisiri rakachena radial simba, rinokonzera kubereka kupisa.Edza kutwasanudza shaft yakakotama kana kuitsiva neberero idzva

2. Nzira yekudzivirira sei kutakura motokari kubva pakupisa?

Inogona kutariswa kuviga tembiricha yekuyera chinhu padhuze nekutakura, uye wozodzivirira kutakura kuburikidza nedunhu rekutonga.Dhawunirodha Kazhinji, mota ine tembiricha yekuyera chinhu (senge thermistor) mukati memota, uyezve waya mbiri dzinobuda kubva mukati kuti dzibatanidze kune yakakosha dziviriro, uye mudziviriri anotumira inogara 24V voltage, kana mota ichitakura Kana. iyo overheating inodarika kukosha kwakatarwa kwemudziviriri, inofamba uye ichiita basa rekudzivirira.Parizvino, vazhinji vanogadzira mota munyika vanoshandisa iyi nzira yekudzivirira.
