Iibheringi ezincinci – iipleyiti zomzimba ezincinci zokusetyenziswa okukhulu

 

Iibheringi ezincincibhekisa kuthotho lwe-metric, olunobubanzi bangaphandle obungaphantsi kwe-9mm; uthotho lwe-Imperial, zonke iintlobo zeebheringi ezinobubanzi bangaphandle obungaphantsi kwe-9.525mm. Izixhobo eziphambili yintsimbi ethwalayo, intsimbi engatyiwayo, iplastiki, iseramikhi, njl.njl., apho ububanzi bangaphakathi u-Z bunokuba yi-0.6mm, kwaye ububanzi bangaphakathi ngokubanzi yi-1mm.

 

Iibheringi zebhola ezincincizenziwe ngentsimbi yekhabhoni, intsimbi ethwala imithwalo, intsimbi engatyiwayo, iplastiki, iiseramikhi kunye nezinye izinto, zinoluhlu olubanzi lokusetyenziswa, zilungele ukujikeleza ngesantya esiphezulu, i-torque ephantsi yokungqubana, ukungcangcazela okuphantsi, iimfuno zengxolo ephantsi (izinto zentsimbi yekhabhoni azisetyenziswa rhoqo ngabathengi, kubathengi abakumgangatho ophantsi).

 

1. Iimpawu zemveliso

 

Iibheringi ezincincizilungele zonke iintlobo zezixhobo zoshishino, iimoto ezincinci ezijikelezayo, njl.njl.; Kwiminyaka yakutshanje, kubekho ukwanda kwemfuno yezi zixhobo ezincinci, ezikhaphukhaphu, nezinodonga oluncinci.

 

Kwiibheringi ezincinci kakhulu, kukho iintlobo ezili-18 zeebheringi ezincinci ezinobubanzi obungaphakathi obuyi-φ2mm okanye ngaphantsi, kunye neentlobo ezi-6 ze-Imperial R series.

 

2. Iindlela eziphambili zokusetyenziswa

Izixhobo zeofisi Ii-Micro motors, ii-soft drives Ii-pressure rotors, ii-dental drills Ii-hard disk motors, ii-stepper motors Ii-video recorders Ii-magnetic drums, ii-toy model Ii-computer fans, ii-encoders kunye nezinye iindawo.

 

3. Khetha izinto ezili-11 zeebheringi ezincinci

 

Xa ukhetha ii-micro bearings, kufuneka kuqwalaselwe izinto ezininzi ukuze kuthintelwe uhlobo lokukhetha kunye nezinye iimpazamo, kwaye ngoku shwankathela izinto ezili-11 eziphambili zokukhetha ii-micro bearings ukuze ubhekisele kuzo.

 

1. Umthwalo we-radial othwala i-miniature

 

Iibheringi ezithwala kakhulu imithwalo yeradial ziibheringi ezisisembindini. Nge-engile yoqhagamshelwano eqhelekileyo ye-A0≤45°, iibheringi ezijikelezayo ezinobukhulu obufanayo zinokumelana nemithwalo yeradial emikhulu kuneebheringi zebhola.

 

Iibheringi zerola ze-N-type kunye ne-NU cylindrical roller zinokuthwala imithwalo ye-radial kuphela, ngelixa ezinye iintlobo zeebheringi ze-centripetal zinokuthwala imithwalo ye-radial kunye ne-axial.

 

2. Umthwalo we-Axial weebheringi ezincinci

Ibheriyali ethwala kakhulu imithwalo ye-axial idla ngokuba yi-thrust bearing, kwaye i-nominal contact angle yayo A0>45°. Ii-thrust bearings kunye nee-thrust angular contact ball bearings zinokumelana namandla e-axial kwicala elinye okanye omabini ngaxeshanye, kuxhomekeke kwisakhiwo. Xa amandla ebheriyali ephezulu kakhulu, ii-thrust cylindrical roller bearings kunye nee-thrust spherical roller bearings ziyathandwa.

 

Iibheringi zerola ezingqukuva kunye neebheringi zebhola zoqhagamshelwano ze-angular ezijolise ngqo zingathwala zombini imithwalo ye-axial kunye neye-radial, ngelixa ezinye iibheringi ze-thrust zinokuthwala kuphela imithwalo ye-axial.

 

3. Imbuyekezo yobude bebhereyini encinci engeniswe ngaphakathi ngokwayo

 

Ukuxhasa umngxuma kunye nebheriya kudla ngokusebenzisa indibaniselwano yebheriya esisigxina kunye nebheriya yokuhamba. Iibheriya zokuhamba zilungisa iimpazamo zobude bomngxuma kunye nokwandiswa kobushushu.

Iibheringi ze-NU kunye ne-N ezisilinda zilungile kwiibheringi zokuhamba ezihlawulela ubude bazo ngokwazo. Iiringi zangaphakathi nezangaphandle zebheringi zinokufakwa ngokuqinileyo.

 

4. Imbuyekezo yobude bokulingana kokutyibilika kwebhereji encinci

Iibheringi ezincinci ezingahlukaniswayo, ezifana neebheringi zebhola ezinzulu kunye neebheringi zerola ezijikelezayo, zingasetyenziswa njengeebheringi ezihambayo. Enye yeebheringi ezimbini zolu hlobo lwebheringi idityanisiwe kwaye ayinayo indawo yokulungisa i-axial. Ngoko ke, enye yeebheringi zebheringi ingashukunyiswa kumphezulu wayo wokuthwala.

 

5. Iyakwahlulwaiibheringi ezincinci(ukuchaneka)

 

Le yibheri enokufakelwa ngokwahlukeneyo ngeeferrules, kwaye iingenelo zayo ziyabonakala xa zombini iiferrules zifakwe ngokuqinileyo.

 

Iibheringi ezihlukanisiweyo ziquka iibheringi zebhola yoqhagamshelwano ezine-point ezine, iibheringi zebhola yoqhagamshelwano ezine-angled rows ezineering ezimbini zesiqingatha sangaphakathi, iibheringi zerola ezisilinda, iibheringi zerola ezithambileyo, iibheringi zebhola yothotho, iibheringi zerola ezisilinda, kunye neebheringi zerola ezisilinda ezisilinda.

 

Iibheringi ezingahlukaniswayo ziquka: iibheringi zebhola ezinzulu, iibheringi zebhola ezidibanisayo ezikumqolo omnye, iibheringi zebhola ezingqukuva, kunye neebheringi zerola ezingqukuva.

 

6. Ukuthwala okuncinciukuchaneka

 

Kwiimeko ezininzi, kwanele ukusebenzisa iibheringi eziqengqelekayo zobukhulu obuqhelekileyo kunye nokuchaneka kokujikeleza.

 

Xa iimfuno ziphezulu, iibheringi zifuna ukulinganiswa okuchanekileyo okuphezulu.

 

7. Iibheringi ezincincimusa ukubuyisela ukungathathi cala

Ukungalingani kwenzeka xa kucutshungulwa umphezulu wokudibana kwejenali okanye umphezulu wokudibana kwezindlu, ingakumbi xa umphezulu wokudibana ungagqitywanga ngokufakelwa kube kanye. Ukungalingani kunokwenzeka xa kusetyenziswa ii-housings (umzekelo, ii-flange housings okanye ii-housings ezithe nkqo). Xa i-shaft igobile kwaye iguqukile ngenxa yomthwalo osebenzayo, nto leyo ebangela ukuthambeka kweeringi zangaphakathi nezangaphandle zebheri, ukungalingani kuya kwenzeka.

 

Iibheringi ezijikelezayo zinokulungisa ukungalungelelani kunye nokuthambeka, njengeebheringi zebhola ezijikelezayo, iibheringi zerola ezijikelezayo eziphakathi kunye neze-thrust. Ezi bearing zine-concave spherical outer ring raceway apho i-rolling element kunye ne-inner ring zinokujikeleza khona. Amandla ezi bearing okulungisa i-engile yokuphambuka embindini we-shaft axhomekeke kuhlobo lwazo, ubungakanani, kunye neprofayili yomthwalo.

 

Zombini iibheringi ezingqukuva kunye neebheringi zebhola ezithululwayo ezineembaleki zinomphezulu ongqukuva: i-engile yokujika ehlawulelwayo inokulungiswa xa ifakelwe kumdyarho ongqukuva ongqukuva.

 

8. Isantya sokuthwala esincinci

Ukungqubana kweebheringi zomqolo omnye kuphantsi kakhulu, ngoko ke kunokwenzeka ukufikelela kwisantya esiphezulu se-Z. Ezi bearing zifumaneka kwiibheringi zebhola ezinzulu ezinokumelana kuphela nemithwalo yeradial kunye neebheringi zebhola ezidibanisayo ze-angular ezinokumelana nemithwalo edibeneyo.

 

Ukuphucula ukuchaneka kobukhulu, ukuchaneka kokujikeleza kunye nenxalenye yokudibana kwebheriya, ukusetyenziswa kweendlela zokuthambisa kunye nokupholisa, kunye nokusetyenziswa kweentlobo ezikhethekileyo zeekheyiji kunokunyusa isantya sokujikeleza esivumelekileyo sebheriya.

 

Ukusebenza kwengxolo ephantsi

 

Ingxolo ephantsi yokusebenza idla ngokufuneka kwiimoto ezincinci, izixhobo zeofisi kunye nezixhobo zasekhaya.

 

9. Ukuthwala okuncinciumngxuma ojiyileyo

Iibheringi ezineebhore ezikhoni zingafakelwa ngqo kwiijenali ezithambileyo (umz. iibheringi zerola ezisilinda ezijikelezayo ezi-single kunye nezi-double row kwizakhiwo ezichanekileyo kakhulu). Xa ufaka ezi berengingi, indawo ethile evulekileyo ingalungiswa.

 

Uninzi lwee-ball bearings ezingqukuva, ii-drum roller bearings kunye nee-spherical roller bearings ezine-conical bore zinokufakelwa kwi-cylindrical journal ene-tight sleeve. Ezi bearings kulula kakhulu ukuzifaka nokuzisusa.

 

10. Ukuqina kweebheringi ezincinci

 

Ukuqina kweebheringi ezingenisiweyo kudla ngokubhekisa kumandla afunekayo ukuvelisa ukuguquguquka okuthile kwe-elastic kwebheringi. Iibheringi kwi-spindle yomatshini kunye ne-pinion shaft zifuna inqanaba eliphezulu lokuqina. Ngenxa yeemeko ezahlukeneyo zoqhagamshelwano phakathi kwento eqengqelekayo kunye nendlela yokugijima, ukuqina kweebheringi zeroli kuphezulu kunokweebheringi zebhola.

 

11. Ukungqubana kweebhereyitha ezincinci

 

Ukongeza ekubeni ifudunyezwe kwaye ichitheke, ukungqubana kwangaphakathi kukwadlala indima ebalulekileyo ekumiseleni ubushushu bokusebenza kwebheriya. Iibheringi eziphantsi zokungqubana zezi: iibheringi zebhola ezinzulu ezinemithwalo ye-radial, iibheringi zebhola zoqhagamshelwano ezi-miniature single-row angular kunye neebheringi zerola ezisilinda ezineekheji. Iibheringi ezitywiniweyo zoqhagamshelwano, iibheringi zerola ezisilinda ezigcweleyo, kunye neebheringi zerola ezithululwayo zonke zivelisa ukungqubana okuphezulu.
