Yintoni umahluko phakathi kwee-cylindrical roller bearings kunye nee-needle roller bearings?

 

Iibheringi zerola ezisilinda

Iibheringi zerola ezisilindazezeebheringi ezichanekileyo, kwaye isikhokelo seflange se-roller post bearing ehlelwe ngokuchanekileyo senziwe yikheyiji, iirola kunye neringi yeshaft yesikhokelo, enokwahlulwa kwenye iringi yebheringi kwaye yeyebheriya enokwahlulwa. Olu hlobo lwebheringi kulula ngakumbi ukuyifaka nokuyiqhaqha, ingakumbi xa iiringi zangaphakathi nezangaphandle, iishaft kunye nee-housings kufuneka zivumelane nokuphazamiseka.

 

Ezi bearing zihambelana ngokuthe ngqo neendlela zomdyarho. Umthamo womthwalo mkhulu, kwaye ikakhulu uthwala imithwalo ye-radial. Iibearing ezimqolo omnye kuphela ezineeflanges kwizangqa zangaphakathi nezangaphandle ezinokuthwala umthwalo omncinci we-axial oqhubekayo okanye umthwalo omkhulu we-axial oqhubekayo; Xa kuthelekiswa nezinye iibearing zokuqokelela ezinemilinganiselo efanayo, olu hlobo lwebearing luneempawu zomthwalo ophezulu, ingxolo esezantsi kunye nesantya esiphezulu, kwaye ukungqubana phakathi kwento eqengqelekayo kunye ne-ring flange kuncinci, kwaye kufanelekile ukujikeleza ngesantya esiphezulu. Ilungele ukusetyenziswa kuzo zonke iintlobo zoomatshini bokuchaneka kunye noomatshini bokugrumba bemigodi. Nangona kunjalo, iishafts, izinto eziqengqelekayo kunye nezinye iindawo ezinxulumene nazo ezihambelana neebearing ezinjalo kufuneka zenziwe ngomatshini ochanekileyo.

 

Ukuba iringi ineflange okanye ayinayo, ingahlulwa ibe yi-NU, NJ, NUP, N, NF kunye nezinye iibheringi zeroli ezisilinda esinye, kunye ne-NNU, NN kunye nezinye iibheringi zeroli ezisilinda ezimbini. Ibheringi sisakhiwo esinokuhlukaniswa esineringi yangaphakathi kunye neringi yangaphandle.

 

Iibheringi zerola ezisilindangaphandle kweeflanges kwizangqa zangaphakathi okanye zangaphandle zinokushukunyiswa ngokwe-axial kwaye zingasetyenziswa njengee-free-end bearings. Ii-cylindrical roller bearings ezineeflanges ezimbini kwicala elinye lezangqa zangaphakathi nezangaphandle kunye neflange enye kwelinye icala le-ferrule zinokumelana nomthwalo othile we-axial kwicala elinye. Ngokubanzi, kusetyenziswa iikheji zokunyathela zepleyiti yentsimbi, okanye iikheji eziqinileyo ezijikiweyo ze-copper alloy. Nangona kunjalo, ezinye iikheji zenziwe kusetyenziswa i-polyamide.

 

Iibheringi zerola zeenaliti zekomityi ezivulekileyo ezitsalwa

 

Iibheringi zerola yenaliti

Iibheringi zeenaliti ziibheringi zeentambo ezineeroli ezisilinda, ezibhityileyo nezinde xa kuthelekiswa nobubanzi bazo. Ezi roli zibizwa ngokuba ziiroli zeenaliti. Nangona zincinci, iibheringi zinomthwalo omkhulu, kwaye iibheringi zeenaliti zixhotyiswe ngeeroli ezibhityileyo nezinde (ububanzi beeroli D).≤5mm, L/D≥2.5, L bubude berola), ngoko ke uyilo lweradial luncinci, kwaye ububanzi bayo bangaphakathi kunye nomthamo womthwalo ziyafana nezo zezinye iintlobo zeebheringi, kunye nobubanzi obuncinci bangaphandle, obufaneleke ngakumbi kwizakhiwo zenkxaso ezinemilinganiselo emincinci yokufakelwa kweradial.

 

Ke ngoko, iibheringi zeenaliti zisetyenziswa kakhulu kwiimeko ezixinzelelweyo, ngoko ke zisetyenziswa kakhulu kwiimoto, kwiibhayisekile, nakwiimashini zelaphu. Kwaye iringi yangaphakathi yenaliti iyimfuneko, ukuba ubunzima kunye noburhabaxa beshaft buyahlangabezana neemfuno, awunakukwazi ukufanisa iringi yangaphakathi (indawo incinci), kodwa ukuba inqanaba lomatshini we-shaft liphantsi, okanye lithambile, kufuneka ufanise iringi yangaphakathi njengendlela yokugijima.

 

Umahluko phakathiiibheringi zerola ezisilinda kunye neebheringi zerola yeenalitizezi zilandelayo:

 

1. Into eqengqelekayo ye-roller bearing esilinda yi-roller enciphileyo; Izinto eziqengqelekayo zee-needle roller bearing zii-roller ezimile okwenaliti;

 

2. Ulwakhiwo lweebheringi zerola ezisilinda likhulu kunezo zeebheringi zerola yeenaliti;

 

3. Ukongeza kumandla e-radial, i-cylindrical roller inokumelana namandla e-axial, ngelixa i-needle roller bearing inokuthwala kuphela amandla e-radial;

 

4. Iibheringi ze-cylindrical roller zahlulwe zaba yimigca enye, imigca ephindwe kabini kunye nemigca emininzi, esetyenziswa kwiindawo ezahlukeneyo kunye neziganeko;

 

5. Isantya sokusebenza kweebheringi zerola ezisilinda siphezulu kuneso seebheringi zerola zeenaliti;

 

6. Iibheringi ze-cylindrical roller ngokubanzi zenziwe ngentsimbi ekumgangatho ophezulu kunye nentsimbi ekhethekileyo; Iibheringi ze-needle roller ezineendonga ezincinci zigximfizwe ngeepleyiti zentsimbi. 

 

Uyisebenzisa nini

 

Kuyilo loomatshini, ubukhulu bomngxuma buqhele ukugqitywa kuqala, uze emva koko i-rolling bearing ikhethwe ngokobukhulu bomngxuma. Nangona kunjalo, xa i-bearing ilinganiselwe kwicala lobubanzi bomatshini, kukhethwa ii-needle roller bearing, ii-ball okanye ii-roller bearing zokukhanya okungaphezulu kunye nochungechunge lwe-ultra-light; Xa indawo ye-axial ye-bearing kumatshini ilinganiselwe, uthotho oluncinci okanye oluncinci kakhulu lwee-ball okanye ii-roller bearing ziyafumaneka.

 

Izixhobo ze-radial needle roller kunye neekheyiji, ii-stamped outer ring needle roller bearings, ii-solid ring needle roller bearings, ii-thrust needle roller bearings zisetyenziswa kakhulu kwinkqubo yokudlulisela, inkqubo yokuqhuba, intonga yokudibanisa injini yebhayisekile yeemoto kunye noomatshini bokwakha, njl.njl., kwaye zifanelekile kwiimeko ezinesithuba esincinci kunye nomthamo omkhulu wokuthwala. Ii-needle roller bearings zixhotyiswe ngee-roller ezincinci nezinde (ubude be-roller buphindwe ka-3 ~ 10 ububanzi, kwaye ububanzi ngokubanzi abudluli kwi-5mm), ngoko ke isakhiwo se-radial sincinci, kwaye ubungakanani baso bobubanzi bangaphakathi kunye nomthamo womthwalo ziyafana nezo zezinye iintlobo zee-bearings, kwaye ububanzi bangaphandle bubuncinci, obufaneleke ngakumbi kwiziphumo zenkxaso apho ubungakanani bofakelo lwe-radial bulinganiselwe.
