Ingcaciso eneenkcukacha zeibhereyithaiintlobo ezihlelwe ngokweempawu zokusetyenziswa

Ngokweemeko zokusebenza ezahlukeneyo kunye neemfuno zokusetyenziswa, iibheringi zingahlulwahlulwa zibe ziindidi ezilandelayo:iibheringi zobushushu obuphezulu, iibheringi zobushushu obuphantsi, iibheringi ezimelana nokugqwala, iibheringi ezimelana nesalfure, iibheringi ezichasene nemagnethi, iibheringi zevacuum, iibheringi ezizithambisayo, iibheringi zeseramikhi kunye neebheringi zesantya esiphezulu.

 

1.Iibheringi zobushushu obuphezulu

Ifanelekile kwizicelo ezinamaqondo obushushu angaphezulu kwe-120°C, kwaye isetyenziswa kakhulu kwiinjini ze-aerojet, ii-atomic reactors, iityhubhu ze-X-ray, izixhobo zokwenza i-semiconductor, kunye nezixhobo zokunyibilikisa, zokugquma kunye nezokufaka i-electroplating.

 

2. Iibheringi zobushushu obuphantsi

Yenzelwe amaqondo obushushu aphantsi kakhulu angaphantsi kwe--60°C, njengeempompo ze-LNG, iipompo ze-nitrogen/hydrogen ezingamanzi, iipompo ze-butane, izixhobo zokuqhuba ulwelo kwi-spacecraft kunye nee-missile. Izakhiwo eziqhelekileyo zii-single row deep groove ball bearings kunye nee-cylindrical roller bearings.

 

3. Iibheringi ezimelana nokugqwala

Isetyenziswa kwiindawo ezifumileyo okanye ezirhabaxa, ezifana namanzi olwandle, umphunga kunye neendawo ezine-asidi-alkali. Yenziwe kakhulu ngezinto zentsimbi engagqwaliyo (ezifana ne-9Cr18 kunye ne-9Cr18Mo), kwaye ikheyiji idla ngokwenziwa nge-0Cr19Ni9 okanye i-beryllium bronze; Intsimbi engagqwaliyo enobushushu obuphezulu efana ne-Cr14Mo4 isetyenziswa kwiindawo ezinobushushu obuphezulu; Kwiibheringi ezinkulu, iintsimbi ezingagqwaliyo ze-martensitic (ezifana ne-1Cr13 kunye ne-2Cr13) zenziwe kakhulu ngonyango lwe-surface nitriding.

 

4. Iibheringi ezimelana nesalfure

Kwi-hydrogen sulfide (H? S) yeendawo ezirhabaxa zegesi. Intsimbi eqhelekileyo yokuthwala kulula ukuyitshabalalisa ngenxa yokubhitya kwe-hydrogen okanye ukugqwala kwe-electrochemical, ngoko ke kuyimfuneko ukusebenzisa iibheringi zezinto ezikhethekileyo ezenziwe ngee-alloys ze-nickel-chromium ezifana ne-00Cr40Ni55A13, kodwa ubunzima bayo (51~55HRC) buphantsi kancinci, amandla okuthwala anqongophele, kwaye ingqalelo ekhethekileyo kufuneka inikwe kwi-integrity yomphezulu xa isetyenziswa.

 

5. Iibheringi ezichasene nemagnethi

Yenziwe ngezinto ezingezizo imagnethi, ayinamanzi aneleyo kwaye ifanelekile ukusetyenziswa kwiindawo ezineemagnethi ezinamandla. I-Beryllium bronze (QBe2) sisixhobo esisetyenziswa rhoqo esinamandla kakhulu, ukuthamba, ukumelana nokuguguleka kunye nokumelana nokugqwala, kwaye isetyenziswa kakhulu emoyeni, emanzini olwandle nakwezinye iindawo.

 

6. Ukuthwala i-vacuum

Isetyenziswa kwindawo ene-vacuum ephezulu (i-vacuum degree ephezulu kune-1.33Pa), kwaye isetyenziswa kakhulu kwizixhobo zeenqwelo-moya, iityhubhu ze-X-ray, iimagnetrons kunye nezinye izinto ezisetyenziswayo. Ulwakhiwo oluqhelekileyo zii-deep groove ball bearings okanye ii-angular contact ball bearings, ezihlala zenziwe ngezinto zentsimbi engagqwaliyo ezifana ne-GCr15 bearing steel okanye i-9Cr18, kwaye ii-alloys ezintsha ezifana ne-G60 zisetyenziswa kwezinye izihlandlo ze-vacuum ezinoxinzelelo oluphezulu.

 

7. Iibheringi ezizithambisayo

Inendlela yokuthambisa eyakhelwe ngaphakathi kwaye ayifuni nkqubo yokuthambisa yangaphandle. Ulwakhiwo oluqhelekileyo luquka iibheringi zebhola yoqhagamshelwano yomgca omnye kunye neebheringi zerola ezimfutshane ze-radial zezixhobo apho ukuthambisa kunqongophele okanye kunzima ukukugcina.

 

8. Iibheringi zeseramikhi

Ziqhelanise neemeko zokusebenza ezigqithisileyo, ezifana nesantya esiphezulu, ubushushu obuphezulu, ubushushu obuphantsi, ukugqwala okunamandla, amandla emagnethi aqinileyo, i-vacuum kunye nendawo enoxinzelelo oluphezulu. Ilungele ukusetyenziswa okuphezulu ngenxa yomthamo wayo ophezulu wokuthwala, ukumelana nobushushu okugqwesileyo, isantya esiphezulu, ukungqubana okuphantsi, ubomi obude, ukumelana nokugqwala kunye nokufakelwa kombane okuhle.

 

9. Iibheringi zesantya esiphezulu

Ifanelekile kwiixabiso ze-Dm·n ezidlula i-1.0×10 mm·r/min (i-Dm bububanzi obuphakathi bento eqengqelekayo, i-n sisantya seringi yangaphakathi). Okwangoku, ixabiso lidlule kwi-3.0×10, kwaye lifikelele nakwi-3.5×10, esetyenziswa kakhulu kwizixhobo zoomatshini ezihamba ngesantya esiphezulu, kwizixhobo zeenqwelo moya nakwizixhobo zokuchaneka.
