Iibheringi zobushushu obuphezulu

Yintoni iBearing yoBushushu obuPhezulu?

I-bearing ebizwa ngokuba yi-high-temperature bearing ibhekisa kubushushu bokusebenza obuphezulu kunobushushu be-bearing eqhelekileyo, kwaye i-bearing esetyenziswa kubushushu bokusebenza obuqhelekileyo obungaphezulu kwe-150 degrees.° ibizwa ngokuba yi-bearing enobushushu obuphezulu.

 

Iimpawu zeebheringi zobushushu obuphezulu:

 

1. Ukuthambisa ubomi bonke, akukho grisi yongezwayo ngexesha lokusetyenziswa.

 

2. Ixabiso layo liphantsi, umgangatho uphezulu amaxesha amaninzi kunoweebheringi eziqhelekileyo.

 

3. Izuze ukuthenjwa ngabathengi bethu ngobomi benkonzo ende.

 

4. Iibheringi ezinobushushu obuphezulu zisetyenziswa kakhulu kwi-metallurgy, kwii-ovens, kwiglasi, kwii-ovens eziqhumayo, kwizixhobo zokupeyinta nakwezinye iimatshini eziphantsi kwemisebenzi yobushushu obuphezulu.

 

Iibheringi zobushushu obuphezulu zisetyenziswa kakhulu kwiinjini zejethi zeenqwelo moya, iiturbine zegesi, iinkqubo ze-reactor zenyukliya, iidiski ze-tungsten zetyhubhu ye-X-ray, izithuthi ezihamba ngesantya esiphezulu, iirokhethi, kunye neenqanawa zeenqwelo-moya.

 

Ukufakelwa kweebheringi zobushushu obuphezulu

Ukongeza, ukuba uxinzelelo lufakwa kwelinye icala leringi (njengeringi engaphandle), kwaye elinye icala leringi (njengeringi engaphakathi) licinezelwe kuyo ngesixhobo sokuqengqeleka, oku kuya kubangela ukuxinana okanye ukukrala kumphezulu wokuqengqeleka, kwaye akufuneki kusetyenziswe, ingakumbi ukuba i-bearing engahlukaniyo ifakwe kwi-shaft nakwi-bearing housing ngaxeshanye.

 

Kwinkqubo yokufudumeza nokufaka i-bearing, kuyimfuneko ukuqonda uluhlu lobushushu be-bearing yobushushu obuphezulu phantsi kwee-bearing ezahlukeneyo zobushushu obuphezulu.

 

Ukufaneleka kweiibheringi zobushushu obuphezulu

1. Ukuphazamiseka

 

Indandatho yangaphakathi kunye nendandatho yangaphandle yento eqengqelekayo zinamathele kwi-shaft okanye kwibhokisi yebheriya, kwaye xa ilayishwa, indandatho kunye nebhokisi yebheriya azinazo iintshukumo ezinxulumene ne-radial, axial kunye ne-rotational relative movements, kwaye olu hambo oluhambelanayo luya kubangela ukungqubana, ukungqubana kokugqwala okanye ukuqhekeka kokungqubana kumphezulu wokudibana, ukuze kubangele umonakalo kwi-bearing, shaft kunye nebhokisi yebheriya, kwaye emva koko umgubo we-abrasion uxutywe kwi-beriya, nto leyo eba yimbangela yokusebenza kakubi, ukufudumeza okungaqhelekanga okanye ukungcangcazela.

 

Ngokuphathelele indlela yokuthwala engaguqukiyo, kungcono ukushiya ubungakanani bokuphazamiseka kumphezulu wokudibana kweringi kunye ne-shaft okanye indlu yebheringi, kwaye ukulingana okungaguqukiyo kulunge kakhulu, ukuze umthwalo weringi enodonga oluncinci usasazwe ngokulinganayo kumjikelezo ngaphandle kokuchaphazela umthamo womthwalo webheringi.

 

Nangona kunjalo, ukongeza kwingxaki yokuncamathisela nokuhlisa i-bearing, ayinakusetyenziswa kuzo zonke iimeko xa i-bearing yahlulwe kwaye ayinakushukunyiswa nge-axial xa i-bearing yahlulwe xa kusetyenziswa i-bearing.

 

2. Ukukhetha indlela yokulingana

 

Ukukhetha indlela yokufaneleka ngokubanzi kwenziwa ngokwemigaqo elandelayo:

 

(1) Ngokwendlela kunye nohlobo lomthwalo osebenza kwi-bearing kunye nokuba leliphi icala leendandatho zangaphakathi nezangaphandle ezijikelezayo, umthwalo othwalwa yiringi nganye unokwahlulwa ube ngumthwalo ojikelezayo, umthwalo ongaguqukiyo, okanye umthwalo ongaguqukiyo, iringi ethwala umthwalo ojikelezayo kunye nomthwalo ongaguqukiyo kufuneka ithathe indawo engaguqukiyo (ukulingana kokuphazamiseka), iringi ethwala umthwalo ongaguqukiyo ingathatha indawo yokutshintsha okanye indawo eguquguqukayo (ukulingana kokuvula), xa umthwalo we-bearing mkhulu okanye uthwala umthwalo wokungcangcazela kunye nowokutsha, ukuphazamiseka kufuneka kwandiswe, xa kusetyenziswa i-shaft engenanto, ibhokisi ye-bearing eneendonga ezincinci okanye i-alloy ekhanyayo kunye nebhokisi ye-bearing yeplastiki, Kwakhona kuyimfuneko ukwandisa ubungakanani bokuphazamiseka.

 

(2) Xa kufuneka kugcinwe ukuchaneka okuphezulu kokujikeleza, kufuneka kusetyenziswe iibheringi ezichanekileyo kakhulu, kwaye ukuchaneka kobukhulu beeshafts kunye neebhokisi zeebheringi kufuneka kuphuculwe, ukuze kuthintelwe ukuphazamiseka okugqithisileyo, ukuba ukuphazamiseka kukhulu kakhulu, ukuchaneka kwejometri yebhokisi yeebheringi okanye ye-axle kunokuchaphazela ijometri yeringi yeebheringi, ngaloo ndlela konakalisa ukuchaneka kokujikeleza kweebheringi, ukuba iiringi zangaphakathi nezangaphandle zeebheringi ezingahlukanisiyo (ezifana neebheringi zebhola ezinzulu) zihambelana ngokuzenzekelayo, ngoko ukufakwa kweebheringi kunye nokuqhekeka kwazo akulunganga kakhulu, kwaye kungcono ukusebenzisa ukulingana okuguquguqukayo kwelinye icala leringi yangaphandle.

 

3. Kucetyiswa ukusebenzisana

 

Ngokuphathelele ububanzi bomngxuma kunye nobukhulu bebhore bomngxuma kunye nendlu yeebheringi apho iibheringi zifakelwe khona, i-ISO283 (ubukhulu bokunyamezela kunye nokulingana) yamkelwe kuthotho lwe-metric, ngoko ke ukunyamezelana kokulingana kumiselwe ngokwebubanzi bomngxuma kunye nobukhulu bebhorengi obukhethiweyo.
