Ulwazi olusisiseko lokuthwala

Njengenxalenye ebalulekileyo yoomatshini banamhlanje, iibheringi zisetyenziswa kakhulu. Sonke siyazi kwaye siyazi okungakumbi okanye kancinci ngayo.

Iibheringingokubanzi ziquka iringi yangaphakathi, iringi engaphandle, izinto eziqengqelekayo kunye nekheyiji. Kwiibheringi ezivaliweyo, yongeza i-lubricant kunye nezitywini (okanye izikhuselo). Yiloo nto iibheringi zimalunga nayo.

Ngokweemeko zokusebenza zebheri, iintlobo ezahlukeneyo zeebheri zinokukhethwa ukuze zidlale ngcono umsebenzi webheri kwaye zandise ubomi benkonzo yebheri. Kufuneka siqwalasele ezi zinto zilandelayo xa sikhetha iibheri:

Umthwalo we-radial

Umthwalo we-Axial

Iimfuneko ze-RPM

Ukuphuma kwe-radial

Ukubaleka kwe-Axial

Ubushushu bokusebenza

Iimfuneko zengxolo

Imeko yokuthambisa

 

Imodeli yokuthwala idla ngokuba nekhowudi yangaphambili, ikhowudi esisiseko kunye nekhowudi yeposi. Ngokubanzi, uphawu lokuthwala luboniswa kuphela luphawu olusisiseko. Imodeli esisiseko ngokubanzi inamacandelo amathathu, ikhowudi yohlobo, ikhowudi yobungakanani kunye nekhowudi yobubanzi bangaphakathi. Ikhowudi yeposi yenzelwe ukusebenzisa oonobumba namanani ukubonisa ulwakhiwo, ukunyamezelana kunye neemfuno ezikhethekileyo zezinto. Ikhowudi yokuqala isetyenziselwa ukubonisa izinto ezincinci zokuthwala, eziboniswa ngoonobumba.

 

1. Igama lekhowudi elisisiseko

Ikhowudi esisiseko isetyenziselwa ukubonisa ububanzi bangaphakathi, uthotho lobubanzi, uthotho lobubanzi kunye nohlobo lokuthwala, ngokubanzi ukuya kuthi ga kwiinombolo ezintlanu, ngolu hlobo lulandelayo:

1) Ububanzi bangaphakathi bebhereyitha buboniswa yinombolo yokuqala ukusuka ekunene kwekhowudi esisiseko.

Ububanzi bangaphakathi bebheri enobubanzi obuqhelekileyo bangaphakathi be-d=20~480mm ngokubanzi buyi-multiple ye-5, kwaye la manani mabini amele i-quotient yobukhulu bobubanzi bangaphakathi bebheri obuhlulwe ngo-5, njengo-04 means d=20mm; 12 means d=60mm njalo njalo. Kwiibheri ezinobubanzi bangaphakathi be-10mm, 12mm, 15mm kunye ne-17mm, iikhowudi zobubanzi bangaphakathi yi-00, 01, 02 kunye ne-03 ngokwahlukeneyo. Kwiibheri ezinobubanzi bangaphakathi obungaphantsi kwe-10mm nangaphezulu kwe-500mm, indlela yokumelwa kobubanzi bangaphakathi ichaziwe ngenye indlela, nceda ubhekisele kwi-GB/T272-93.

 

2) Uthotho lobubanzi bebheri (oko kukuthi, uthotho lotshintsho kububanzi bangaphandle kunye nobubanzi bebheri enesakhiwo esifanayo kunye nobubanzi obufanayo bangaphakathi) luboniswa yidijithi yesithathu ukusuka ekunene kwekhowudi esisiseko.

Umzekelo, kwiibheringi zeradial kunye neebheringi zeradial thrust, u-0 kunye no-1 zibonisa uthotho lokukhanya okungaphezulu; u-2 ubonisa uthotho lokukhanya; u-3 ubonisa uthotho oluphakathi; u-4 ubonisa uthotho olunzima. Uthelekiso lobungakanani phakathi kothotho luboniswe kumfanekiso ongezantsi. Ngaphandle kothotho lokukhanya okungaphezulu kunye no-1, i-thrust bearing ihambelana nokubonakaliswa kwe-radial bearing.

3) Uthotho lobubanzi bebheri (oko kukuthi, uthotho lotshintsho kububanzi bebheri enesakhiwo esifanayo, ububanzi bangaphakathi kunye noluhlu lobubanzi) luboniswa yidijithi yesine ukusuka ekunene kwekhowudi esisiseko.

Xa uthelekiso lothotho lwedayamitha yoluhlu lobubanzi beMifanekiso 13-4 ludweliswe njengoluhlu lwe-0 (uthotho oluqhelekileyo), ikhowudi yoluhlu lobubanzi O ayinakumakishwa kwikhowudi yeebheringi ezininzi, kodwa kwiibheringi ze-spherical roller kunye neebheringi ze-tapered roller, ikhowudi yoluhlu lobubanzi engu-0 kufuneka imakishwe. Iikhowudi zothotho lwedayamitha kunye neekhowudi zothotho lobubanzi zibizwa ngokuba ziikhowudi zothotho lobungakanani.

 

4) Ikhowudi yohlobo lwebhereyitha imelwe yinombolo yesihlanu ukusuka ekunene kwekhowudi esisiseko (kwiibheringi zerola ezisilinda kunye neebheringi zerola yeenaliti, ikhowudi yileta).

 

2. Ikhowudi yeposi

Ikhowudi yeposi yebhereyitha kukusebenzisa oonobumba namanani ukubonisa ulwakhiwo, ukunyamezelana kunye neemfuno ezikhethekileyo zezinto ezisetyenzisiweyo. Kukho umxholo omninzi weekhowudi zeposi, kwaye nazi amagama ambalwa ekhowudi asetyenziswa rhoqo.

1) Ikhowudi yesakhiwo sangaphakathi imele ukubonisa isakhiwo sangaphakathi esahlukileyo sohlobo olufanayo lwebheriya, esiboniswa ngoonobumba abalandelwa yikhowudi esisiseko. Umzekelo, iibheringi zebhola yoqhagamshelwano ezi-angular ezinee-engile zoqhagamshelwano ze-15°, 25° kunye ne-40° zimelwe yi-C, AC kunye ne-B ngokulandelelana ukumela umahluko kwisakhiwo sangaphakathi.

2) Umgangatho wokunyamezelana kwebheri wahlulwe waba ngamabakala ama-2, amabakala ama-4, amabakala ama-5, amabakala ama-6, amabakala ama-6X kunye namabakala angama-0, onke amabakala ama-6, ukusuka phezulu ukuya kwesezantsi, kwaye iikhowudi zazo yi-/PZ, /P4, /PS, /P6, /P6X kunye ne-/PO. Phakathi kweeklasi zokunyamezelana, udidi lwe-6X lusebenza kuphela kwiibheringi zerola ezithambileyo; Udidi lwe-0 ludidi oluqhelekileyo, olungaphawulwanga kwikhowudi yokuthwala ivili.

3) Uthotho lwe-bearing radial clearance olusetyenziswa rhoqo lwahlulwe lwaba liqela eli-1, amaqela ama-2, amaqela angama-0, amaqela ama-3, amaqela ama-4 kunye namaqela ama-5, amaqela ama-6 ewonke, kwaye i-radial clearance isusela kwencinci ukuya kwenkulu. I-Group o clearance liqela le-clearance elisetyenziswa rhoqo, elingaphawulwanga kwi-bearing code, kwaye amanye amaqela e-clearance amelwe yi-/CI, /CZ, /C3, /C4 kunye ne-/CS kwi-bearing code.

 

3. Ikhowudi yangaphambili

Isihlomelo sokuqala sebheriya sisetyenziselwa ukubonisa iinxalenye ezincinci zebheriya, eziboniswa ngoonobumba. Umzekelo, u-L usetyenziselwa ukumela indandatho enokuhlukaniswa yebheriya enokuhlukaniswa; u-K umele izinto eziqengqelekayo kunye nezinto zekheyiji zebheriya, njl.

 

Kukho iintlobo ezininzi zee-rolling bearings kwizicelo ezisebenzayo, kwaye ii-bearing codes ezihambelanayo nazo ziyinkimbinkimbi ngakumbi. Ikhowudi echazwe apha ngasentla yeyona nxalenye isisiseko nesetyenziswa kakhulu kwi-bearing code, kwaye ungayibona kwaye uyijonge i-bearing esetyenziswa rhoqo ukuba uyayazi le nxalenye yekhowudi. Ukuze ufumane indlela eneenkcukacha zekhowudi yee-rolling bearings, nceda ujonge kwi-GBT272.
