1. Iibheringi ezijikelezayozihlelwa ngokwecala lomthwalo ezinokuwuthwala okanye ngokwe-engile yoqhagamshelwano oluqhelekileyo:

 

a) Iibheringi zeRadial — ezisetyenziselwa kakhulu ukuthwala imithwalo yeradial, ene-engile yoqhagamshelwano oluqhelekileyo eyi-0°≤τ≤30°. Ngokwee-engile ezahlukeneyo zoqhagamshelwano oluqhelekileyo, zingahlulwahlulwa zibe:

 

1) Iibheringi ezingqukuva zoqhagamshelwano lwe-Radial contact — iibheringi ezine-engile yoqhagamshelwano oluqhelekileyo τ=0°. Zifanelekile ukuthwala imithwalo ye-radial kwaye zikwazi nokuthwala imithwalo emincinci ye-axial kulo naliphi na icala;

 

2) Iibheringi ze-engile contact radial spherical— iibheringi ezinee-engile yoqhagamshelwano eqhelekileyo engu-0°<τ≤30°. Ifanelekile kwimithwalo edibeneyo enezixhobo ze-radial kunye ne-axial.

 

b) Iibheringi zokutyhala — ezisetyenziselwa kakhulu ukuthwala imithwalo ye-axial, ene-engile yoqhagamshelwano oluqhelekileyo engama-30°<τ≤90°. Ngokwee-engile zoqhagamshelwano oluqhelekileyo ezahlukeneyo, zingahlulwahlulwa zibe:

 

1) Iibheringi ze-Axial contact thrust ezizii-spherical bearings — iibheringi ze-thrust ezine-engile yoqhagamshelwano eqhelekileyo τ=90°. Zifanelekile ukuthwala imithwalo ye-axial kwicala elinye;

 

2) Iibheringi ezingqukuva zokudibanisa ezijikelezileyo — iibheringi ezingqukuva ezinee-engile yokudibanisa eqhelekileyo engama-30°<τ<90°. Zilungele kakhulu imithwalo ye-axial yokuthwala, kodwa zinokuthwala imithwalo edibeneyo.

 

2.Iibheringi ezijikelezayozihlulwe ngokwesakhiwo seringi engaphandle:

 

a) Isalathiso sangaphandle sesangqa esinye esingqukuva;

 

b) Ibhereyitha engqukuva yangaphandle yesangqa esinye;

 

c) Ibhereyitha engqukuva yangaphandle ephindwe kabini;

 

d) Ibhereyitha engqukuva yangaphandle eneziqwenga ezibini.

 

3. Iibheringi ezijikelezayozihlulwe ngokwendlela ezincamatheliswe ngayo kwisiphelo sentonga:

 

a) (Ngokubanzi) iibheringi ezingqukuva;

 

b) Iibheringi zesiphelo sentonga, ezineendlela ezininzi zokuhlela:

 

1) Ngokweendawo ezidibana nesiphelo sentonga:

 

— I-bearing engqukuva yentonga edibeneyo: i-bearing engqukuva ene-bore esisilinda, ene-bearing engqukuva ye-radial efakwe kwi-bore, ene-bolt okanye engenayo;

 

— Isiphelo sentonga esinye sijikelezileyo: isiphelo sentonga esinembobo yangaphakathi engqukuva, kunye neringi yangaphakathi yembobo efakwe kwimbobo, inebholiti okanye ingenalo;

 

— Isiphelo sentonga yebholiti enentloko yebhola, ibheyaringi engqukuva: isiphelo sentonga esinesihlalo sebhola, apho kufakwa khona ibholiti enentloko yebhola.

 

2) Ngokweempawu zoqhagamshelo lwe-shank yesiphelo sentonga:

 

— Isiphelo sentonga yomsonto sangaphakathi sibhera esingqukuva: isiqu sentonga ngumsonto othe tye onemisonto yangaphakathi;

 

— Isiphelo sentonga yomsonto sangaphandle sibhera esingqukuva: isiqu sentonga ngumsonto othe tye onentambo yangaphandle;

 

— I-Rod end spherical bearing enesiseko esitshisiweyo: i-rod end shank inesihlalo se-flange, isihlalo sesikwere, okanye isihlalo se-cylindrical esineephini zokubeka, ezinamathele kwisiphelo sentonga ngokuwelda;

 

— Ibheri yesiphelo sentonga enesihlalo sokutshixa: isiqu sesiphelo sentonga sinendawo yangaphakathi enentambo enesixhobo sokutshixa.

 

4. Iibheringi ezingqukuva zihlulwe ngokwendlela ezifuna ukuthambisa kwakhona nokugcinwa kwazo ngexesha lokusebenza:

 

a) Iibheringi ezityibiliziweyo ezilungisiweyo ngolondolozo;

 

b) Iibheringi ezizitshisayo ezizilungisayo ezingenazo ii-lubricating bearings.

 

5. Iibheringi ezijikelezayo zihlulwe ngokwendibaniselwano yezinto ezisetyenziselwa iindawo zokutyibilika:

 

a) Iibheringi zentsimbi/zentsimbi ezingqukuva;

 

b) Iibheringi zentsimbi/zethusi ezingqukuva;

 

c) Iibheringi ezidityanisiweyo zentsimbi/PTFE;

 

d) Iibheringi zentsimbi/ze-PTFE zelaphu ezingqukuva;

 

e) Iibheringi zentsimbi/zeplastiki eziqinisiweyo ezijikelezileyo;

 

f) Iibheringi ezingqukuva zentsimbi/zinc.

 

6. Iibheringi ezijikelezayo zihlulwe ngokweeyunithi ezisetyenziselwa ubukhulu kunye nokunyamezelana:

 

a) Iibheringi ezingqukuva zeMetric;

 

b) Iibheringi ezijikelezileyo zobukumkani.

 

7. Iibheringi ezijikelezayo zihlelwe ngokupheleleyo ngokwendlela imithwalo ebekwe ngayo, i-engile yoqhagamshelwano oluqhelekileyo, kunye nohlobo lwesakhiwo:

 

a) Iibheringi ezijikelezayo ze-radial;

 

b) Iibheringi ezingqukuva zoqhagamshelwano lwe-angular;

 

c) Iibheringi ezingqukuva zokutyhala;

 

d)Iibheringi ezingqukuva zesiphelo sentonga.

Iibheringi ezingqukuva nazo zingahlulwa zibe ziintlobo ngeentlobo zezakhiwo ngokwemilo yazo (umz., ukubakho okanye ukungabikho kwezixhobo zokutywina, ulwakhiwo lwemijelo yokuthambisa kunye nemingxunya, ulwakhiwo lwemijelo yokusasaza i-lubricant, inani lemijelo yendandatho yokugcina, icala lokujikeleza kwemisonto yesiphelo sentonga, njl.njl.).
