Chii chinonzi chisimbiso chakanamwa, chine mhando yechisimbiso

 

Izvo zvinonzi sealed bearing ivhu-proof kutakura, kuitira kuti kutakura kuvharwe zvakanaka kuchengetedza kutakura kwakatsetseka mamiriro ezvinhu uye yakajairika nzvimbo yekushanda, kupa kutamba kwakazara kune basa rekutakura, kuwedzera hupenyu hwebasa rekutakura, uye Iva nechisimbiso chakakodzera chebheji inotenderedza kudzivirira kubuda kweiyo inotsvedza mumiriri uye kupinda kweguruva, mhute yemvura kana imwe tsvina. Izvi zvinobatsira pakudzivirirwa kwekutakura.

 

Bearing Seal Type:

TIyo yekuisa chisimbiso chimiro cheanotenderedza mabearings anonyanya kukamurwa kuita zvisimbiso zvekusangana uye zvisimbiso zvisingabatanidzi.

 

Kusina-kubatwa chisimbiso kwemabheri

 

Kutakura kusingabatanidzi chisimbiso inzira yekuisa chisimbiso inogadzira gaka diki pakati peshaft uye chivharo chekupedzisira cheimba inotakura. Iri rudzi rwechisimbiso chimiro hachibatanidzi shaft, saka hapana kupesana uye kupfeka, uye inokodzera kutenderera-kumhanya. Kuwedzera chisimbiso mhedzisiro, gomba rinogona kuzadzwa negirizi. Kutakura zvisimbiso zvisingabatanidzi zvinonyanya zvinosanganisira: gap seal, mafuta groove chisimbiso, labyrinth chisimbiso, oiri slinger seal, nezvimwe.

 

1. Gap sealing

Iyo gap chisimbiso ndeyekusiya diki annular gap pakati pe shaft uye inotakura chivharo kuburikidza negomba, iyo radius gap iri 0.1-0.3mm, iyo yakareba iyo gap iri diki uye idiki, zvirinani kuita chisimbiso.

 

2. Oil groove sealing

 

Iyo mafuta groove chisimbiso inogadziriswa neannular mafuta groove pajenari remukati mevhavha yeinotakura chisimbiso chekupedzisira chivharo, uye oiri gwara regiyo rinogovaniswa radially, uye imwe neimwe annular oiri inotaurirana kuburikidza neoiri inotungamira groove uye inotaurirana netangi remafuta. , uye nhamba yeannular mafuta groove uye mafuta guide groove inotarirwa nehukuru hwechisimbiso chekupedzisira chivharo.

 

3. Labyrinth sealing

Nheyo yekutanga yekuisa chisimbiso iyi kugadzira nzira yekuyerera pachisimbiso nekuramba kukuru kwekuyerera. Zvimiro, kagero kadiki kekurovera kanoumbwa pakati pechikamu chakamira uye chikamu chinotenderera kuita "labyrinth".

 

4. Oil slinger sealing

 

Bata zvisimbiso zvemabheya

Kuvhara chisimbiso ndiyo nzira yekuisa chisimbiso yemagumo kana miromo yekubata shaft yevulcanized synthetic rabha pane skeleton yesimbi, uye kuita kwayo chisimbiso kuri nani pane kuya kwekusaisa chisimbiso, asi kupokana kwakakura, uye tembiricha inokwira yakakwira. Iyo yekubatanidza nzvimbo ye shaft uye chisimbiso inoda kukwizwa, kazhinji ine lubricant yakafanana neyekutakura. Kubata zvisimbiso zvinonyanya zvinosanganisira: inonzwa mhete yekuisa chisimbiso, yeganda mbiya chisimbiso, yekuisa chisimbiso mhete, skeleton kuisa chisimbiso, kuisa chisimbiso mhete, nezvimwe.

 

1. Kunzwa kuiswa chisimbiso chemhete

Trapezoidal groove inovhurwa pachivharo chebearing, uye iyo yakanaka inonzwa yerectangular chikamu inoiswa mu trapezoidal groove kuti ibatane ne shaft, kana gland inotsikirirwa axially kuita kuti inonzwa mhete yakatsikirirwa uye kuburitsa radial pressure kuti ibatisise. iyo shaft, kuitira kuti uwane chinangwa chekuisa chisimbiso.

 

2.Iyo ndiro yeganda yakavharwa

 

Iyo yakavharwa ndiro yematehwe (yakagadzirwa nezvinhu zvakadai semafuta-inodhonzwa rubber) inoiswa muvharo yekutakura uye inotsikirirwa zvakananga kune shaft. Kuti uwedzere kuvharika kwechisimbiso, chitubu chemhete chinotsikirirwa parin'i yemukati yembiya yeganda, kuitira kuti mhete yemukati yendiro yeganda ive yakanyatsoenderana neshaft..

 

3. Mhete yekuisa chisimbiso yakavharwa

Zvisimbiso zvinowanzogadzirwa nematehwe, epurasitiki kana mafuta-inodzivirira rabha uye inogona kugadzirwa mune akasiyana profiles sezvinodiwa. Iyo 0-yakaita chisimbiso mhete ine denderedzwa chimiro, ichivimba neyayo elastic simba kudzvanya pane shaft, ine chimiro chakareruka uye nyore kusangana uye disassembly. J-shaped uye U-shaped zvisimbiso zvakare zvinowanzoshandiswa, zvose zvine chimiro chakaita semuromo.

 

4. Skeleton sealing

 

Kuti uvandudze kusimba kwese kwechisimbiso chedehwe, simbi yesimbi ine L-yakaita muchinjiko-chikamu uye annular shape inoiswa murubha isingaite mafuta, kuitira kuti chisimbiso chedehwe chisave nyore kukanganisa, uye hupenyu hwesevhisi hunovandudzwaPanyaya ye<7m/s, mazhinji ecentrifugal pombi anotakura mabhokisi parizvino akavharwa nema skeleton.

 

5. Kuisa chisimbiso mhete

Iyi imhando yeannular chisimbiso chine notch, inoiswa mumhete groove yeruoko, sleeve inotenderera pamwe chete neshaft, uye mhete yekuisa chisimbiso inotsikirirwa kumadziro emukati megomba rechikamu chakamira nekusimba uko notch inodzvinyirirwa, uye inogona kuita basa rekuisa chisimbiso, uye rudzi urwu rwekuisa chisimbiso rwakanyanya kuoma.

 

Kusarudzwa kwekubereka chisimbiso chimiro

 

Paunosarudza chimiro chekutakura chisimbiso, zvinhu zvikuru zvekufunga nezvazvo ndezvi: lubricant, kureva, kana iri mafuta kana mafuta; Linear velocity yezvikamu zvekuisa chisimbiso; kukanganisa kwekuisa shaft; Saizi uye mutengo wenzvimbo yekuisa, nezvimwe.
