Chii chinonzi bearing yakavharwa, rudzi rwechisimbiso chekutakura

 

Inonzi sealed bearing inodzivirira guruva, kuitira kuti bearing ivharwe zvakanaka kuti bearing irambe yakatsetseka uye nzvimbo yakajairika yekushanda, ipe basa rayo rose, iwedzere hupenyu hwebasa rebearing, uye ive nechisimbiso chakakodzera chebearing inotenderera kudzivirira kubuda kwechinhu chinotsvedzerera uye kupinda kweguruva, utsi hwemvura kana imwe tsvina. Izvi zvinobatsira pakudzivirira bearing.

 

Kubereka Chisimbiso Rudzi:

TChimiro chemuchina wekuvharira mabheyaringi chinokamurwa kuva zvisimbiso zvekusangana nezvisimbiso zvisingaonani.

 

Kuvhara mabheyaringi kusingabatanidzi

 

Kuvhara simbi zvisina kubatana inzira yekuvhara simbi inogadzira mukaha mudiki pakati pemubato nekavha yekupedzisira yeimba yekutakura simbi. Rudzi urwu rwekuvharira simbi harubate mubato, saka hapana kukweshana kana kupera, uye rwakakodzera kutenderera nekukurumidza. Kuti uwedzere kushanda kwekuvhara simbi, mukaha unogona kuzadzwa nemafuta. Zvisimbiso zvisina kubatana zvinosanganisira: mukaha, mukaha, mukaha, mukaha, nezvimwewo.

 

1. Kuvhara mipata

Chisimbiso chegedhi chinofanira kusiya mukaha mudiki pakati pemubato nechivharo chebheyaringi kuburikidza neburi, mukaha weradius uri 0.1-0.3mm, mukaha mudiki uye mudiki kwenguva refu, zvinoita kuti mukaha uve nani.

 

2. Kuvhara gomba remafuta

 

Chisimbiso chemugero wemafuta chinogadziriswa negoho remafuta rinotenderera riri mujenari yemukati megomba rekuvhara chisimbiso chebearing, uye goho remafuta rinotenderera rinoparadzirwa nemwaranzi, uye oiri yega yega inotenderera kuburikidza negoho remafuta rinotenderera uye rinotaurirana netangi remafuta, uye huwandu hwegoho remafuta rinotenderera uye goho remafuta rinotariswa nehukuru hwegoho rekuvhara chisimbiso.

 

3. Kuvhara kweLabyrinth

Nheyo huru yekuvharwa uku ndeyekugadzira nzira yekuyerera pachisimbiso ine simba guru rekudzikamisa kuyerera kwemvura. Muchimiro, mukaha mudiki unotenderera unoumbwa pakati pechikamu chisina kumira nechikamu chinotenderera kuti ugadzire "labyrinth".

 

4. Kuvhara chisimbiso chemafuta

 

Zvisimbiso zvekubata mabheyaringi

Kuvhara jira rekubata (contact sealing) inzira yekuvharira jira rekubata muromo kana muromo werabha yakagadzirwa nesimbi yakasanganiswa, uye kushanda kwayo kwekuvhara jira kuri nani pane kuvharira jira risingasanganisike, asi kukweshana kwacho kwakakura, uye kukwira kwekupisa kwakanyanya. Nzvimbo yekubata jira nejira inofanira kunge yakazorwa mafuta, kazhinji nemafuta akafanana nebheya. Zvisimbiso zvekubata jira zvinonyanya kusanganisira: kuvharira jira remvere, kuvharira jira reganda, kuvharira jira rekubata, kuvharira jira rekubata, kuvharira jira rekubata, nezvimwewo.

 

1. Kuvhara mhete yeFelt

Mugero wetrapezoidal unovhurwa pachifukidziro chebheyaringi, uye chidimbu chechikamu cherectangular chinoiswa mumugero wetrapezoidal kuti chibatane neshaft, kana kuti gland rinodzvanywa neaxial kuti ringi yefelt iomerwe uye ibudise radial pressure kuti ibate pamugero, kuitira kuti chinangwa chekuivhara chibudirire.

 

2.Ndiro yedehwe yakavharwa

 

Ndiro yedehwe yakavharwa (yakagadzirwa nezvinhu zvakaita serabha inodhonzwa nemafuta) inoiswa muchifukidziro chebheyaringi yodzvanywa zvakananga pashaft. Kuti zviwedzere kunaka kwesefa, chitubu chering coil chinodzvanywa parin'i yemukati yedehwe, kuitira kuti rin'i yemukati yedehwe inyatsobatana neshaft..

 

3. Mhete yekuvhara yakavharwa

Zvisimbiso zvinowanzogadzirwa nedehwe, purasitiki kana rabha isingapindi mafuta uye zvinogona kugadzirwa muzvikamu zvakasiyana sezvinodiwa. Mhete yekusimbisa ine chimiro che0 ine chimiro chedenderedzwa, ichivimba nesimba rayo re elastic kuti idzvanye pashaft, ine chimiro chiri nyore uye nyore kuunganidza nekuputsa. Zvisimbiso zvine chimiro cheJ neU zvinowanzoshandiswawo, zvese zvine chimiro chakaita semiromo.

 

4. Kuvhara mapfupa

 

Kuti simba resimbi riwedzere kusimba kwechisimbiso chedehwe, jira resimbi rine chikamu cheL chakaita sedanda uye chimiro che annular rinoiswa murabha rinodzivirira mafuta, kuitira kuti chisimbiso chedehwe chisave nyore kuchichinja, uye hupenyu hwebasa hunovandudzika. Kana iri pasi pe7m/s, mabhokisi mazhinji ekutakura pombi ye centrifugal parizvino akavharwa ne skeleton.

 

5. Kuvhara mhete yekuvhara

Iyi imhando yechisimbiso che annular chine notch, chinoiswa mu ring groove ye sleeve, sleeve inotenderera pamwe chete ne shaft, uye sealing ring inodzvanywa pamadziro emukati megomba rechikamu chisina kusimba nekusimba kwainodzvanywa ne notch, uye inogona kutamba basa re sealing, uye rudzi urwu rwe sealing rwakaoma zvikuru.

 

Kusarudzwa kwechimiro chechisimbiso chekutakura

 

Pakusarudza chimiro chechisimbiso chebheyaringi, zvinhu zvikuru zvekufunga nezvazvo ndeizvi: mafuta, kureva kuti, ingave mafuta kana mafuta; Kumhanya kwemutsara kwezvikamu zvekuvhara; kukanganisa kwekuisa shaft; Hukuru uye mutengo wenzvimbo yekuisa, nezvimwewo.
