Uyini umehluko phakathi kwama-roller bearings ayisilinda kanye nama-needle roller bearings?

 

Ama-roller bearings e-cylindrical

Ama-roller bearings e-cylindricalzingezama-precision bearing, kanti isiqondiso se-flange se-precision-sorted roller post bearing sakhiwe yikheji, ama-rollers kanye nendandatho yomgodi wokuqondisa, engahlukaniswa kwenye indandatho yokuthwala futhi ingeye-separable bearing. Lolu hlobo lokuthwala kulula kakhulu ukulifaka nokuliqaqa, ikakhulukazi lapho izindandatho zangaphakathi nezangaphandle, imiphini kanye nezimbobo kudingeka ukuthi zivumelane nokuphazamiseka.

 

Lawa ma-bearing axhumene ngqo nemigwaqo yomjaho. Umthamo womthwalo mkhulu, futhi ikakhulukazi uthwala imithwalo ye-radial. Ama-bearing omugqa owodwa kuphela anama-flanges kokubili emasongweni angaphakathi nangaphandle angathwala umthwalo omncane we-axial oqhubekayo noma umthwalo omkhulu we-axial oqhubekayo; Uma kuqhathaniswa namanye ama-bearing okuqongelela anezilinganiso ezifanayo, lolu hlobo lwe-bearing lunezici zomthwalo ophezulu, umsindo ophansi kanye nesivinini esiphezulu, kanti ukungqubuzana phakathi kwento egingqikayo kanye ne-ring flange kuncane, futhi kufanelekile ukujikeleza ngesivinini esikhulu. Kuhle ukusetshenziswa nazo zonke izinhlobo zemishini yokunemba kanye nemishini yokugaya yezimayini. Kodwa-ke, imiphini, izinto ezigingqikayo nezinye izingxenye ezihlobene ezihambisana nama-bearing anjalo kudingeka zenziwe ngomshini wokunemba.

 

Ngokuya ngokuthi indandatho ine-flange noma cha, ingahlukaniswa ngama-NU, NJ, NUP, N, NF kanye namanye ama-roller bearings angama-cylindrical angumugqa owodwa, kanye nama-NNU, NN kanye namanye ama-roller bearings angama-cylindrical angumugqa ophindwe kabili. I-bearing iyisakhiwo esihlukanisekayo esinendandatho yangaphakathi nendandatho yangaphandle.

 

Ama-roller bearings e-cylindricalAma-flange angenazo izingcezu emasongweni angaphakathi noma angaphandle angahanjiswa nge-axial futhi angasetshenziswa njengama-free-end bearing. Ama-roller bearing e-cylindrical ane-double flanges ohlangothini olulodwa lwendandatho yangaphakathi neyangaphandle kanye ne-flange eyodwa kolunye uhlangothi lwe-ferrule angamelana nezinga elithile lomthwalo we-axial ohlangothini olulodwa. Ngokuvamile, kusetshenziswa ama-cage okunyathela ipuleti lensimbi, noma ama-cage aqinile aphendulwe nge-copper alloy. Kodwa-ke, amanye ama-cage akhiwa kusetshenziswa i-polyamide.

 

Ama-roller bearings endebe evulekile edonswayo

 

Amabheringi e-needle roller

Ama-needle roller bearings angama-roller bearings anama-cylindrical roller, amancane futhi amade uma kuqhathaniswa nobubanzi bawo. Ama-roller anjalo abizwa ngokuthi ama-needle roller. Naphezu kwezingxenye zawo ezincane, ama-bearings anomthwalo omkhulu, kanti ama-needle roller bearings afakwe ama-roller amancane nande (ububanzi be-roller D).≤5mm, L/D≥2.5, L ubude be-roller), ngakho-ke ukwakheka kwe-radial kuncane, futhi ububanzi bawo bangaphakathi kanye nomthamo womthwalo kufana nobezinye izinhlobo zama-bearings, kanye nobubanzi obuncane bangaphandle, obufanelekela kakhulu izakhiwo zokusekela ezinobukhulu obulinganiselwe bokufaka i-radial.

 

Ngakho-ke, ama-needle roller bearings asetshenziswa kakhulu ngezikhathi ezincishisiwe, ngakho-ke asetshenziswa kabanzi ezimotweni, ezithuthuthu, nasemishinini yendwangu. Futhi indandatho yangaphakathi ye-needle roller iyazikhethela, uma sikubeka ngokusobala, uma ubulukhuni nokuqina kwe-shaft kuhlangabezana nezidingo, awukwazi ukufanisa indandatho yangaphakathi (isikhala sinqunyelwe), kodwa uma izinga lomshini we-shaft liphansi, noma lithambile, udinga ukufanisa indandatho yangaphakathi njengendlela yokugijima.

 

Umehluko phakathiama-roller bearings ayisilinda kanye nama-needle roller bearingsyilezi ezilandelayo:

 

1. Ingxenye yokugoqa ye-cylindrical roller bearing iyi-roller enciphile; Izinto zokugoqa zama-needle roller bearing ziyi-roller ezimise okwenaliti;

 

2. Isakhiwo sama-roller bearings asilinda sikhulu kunesawo ama-roller bearings anenaliti;

 

3. Ngaphezu kwamandla e-radial, i-cylindrical roller ingamelana namandla e-axial, kuyilapho i-needle roller bearing ingakwazi ukuthwala amandla e-radial kuphela;

 

4. Ama-roller bearings e-cylindrical ahlukaniswe ngemigqa eyodwa, imigqa emibili kanye nemigqa eminingi, esetshenziswa ezindaweni ezahlukene kanye nemicimbi;

 

5. Isivinini sokusebenza sama-roller bearings asilinda siphakeme kunese-needle roller bearings;

 

6. Ama-roller bearings e-cylindrical ngokuvamile enziwe ngensimbi ethwalayo esezingeni eliphezulu kanye nensimbi ekhethekile; Ama-roller bearings anezinaliti ezicijile agxivizwe ngamapuleti ensimbi. 

 

Isikhathi sokuyisebenzisa

 

Ekwakhiweni kwemishini, ubukhulu bomgodi ngokuvamile bunqunywa kuqala, bese kuba yi-rolling bearing ekhethwa ngokuya ngobukhulu bomgodi. Kodwa-ke, lapho i-bearing inqunyelwe ohlangothini lobubanzi bomshini, kukhethwa ama-needle roller bearing, ama-ball noma ama-roller bearing okukhanya okwengeziwe kanye nochungechunge lwe-ultra-light; Uma indawo ye-axial ye-bearing emshinini inqunyelwe, kutholakala uchungechunge oluncane noma oluncane kakhulu lwama-ball noma ama-roller bearing.

 

Izingxenye ze-radial needle roller kanye nekheji, ama-stamped outer ring needle roller bearings, ama-solid ring needle roller bearings, ama-thrust needle roller bearings asetshenziswa kabanzi ohlelweni lokudlulisa, uhlelo lokuqondisa, induku yokuxhuma injini yesithuthuthu yezimoto nemishini yokwakha, njll., futhi afaneleka ngezikhathi ezinesikhala esincane kanye nomthamo omkhulu wokuthwala. Ama-needle roller bearings afakwe ama-roller amancane nande (ubude be-roller buphindwe ka-3 ~ 10 ububanzi, kanti ububanzi ngokuvamile abudluli ku-5mm), ngakho-ke isakhiwo se-radial sincane, futhi ubukhulu baso bangaphakathi bobubanzi kanye nomthamo womthwalo kufana nobezinye izinhlobo zama-bearings, kanti ububanzi bangaphandle buncane kakhulu, okufanelekela kakhulu imiphumela yokusekela lapho usayizi wokufakwa kwe-radial unqunyelwe.
