Isikhundla sokuthwala kunye nentsingiselo yaso

 

Ngokuibhereyithaimodeli ikhula kancinci kancinci ngokweemfuno ezahlukeneyo zabantu bangoku, kwaye ngoku inethiwekhi iphuhlisiwe kakhulu, ukuhanjiswa kolwazi nako kuyakhawuleza kakhulu, kwaye kulula ukwazi imodeli yokuthwala. Okulandelayo, siza kukwazisa ngekhowudi esisiseko, ikhowudi yeposi, ikhowudi yangaphambili kunye nolunye ulwazi oluhambelanayo lwethwala.

 

Ukuthwalaisichazi kunye nentsingiselo yaso

 

Iibhereyithaimodeli ngokubanzi inekhowudi yangaphambili, ikhowudi esisiseko kunye nekhowudi yeposi. Ngokubanzi, uphawu lwebhereyitha 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 yesimaphambili isetyenziselwa ukubonisa izinto ezincinci zebhereyitha, eziboniswa ngoonobumba.

 

Indlela yokuchonga iBearing yeNjongo Jikelele (iRolling Bearing)

 

Yahlulwe yaba: ikhowudi yangaphambili, ikhowudi esisiseko kunye nekhowudi yeposi.

 

1. Igama lekhowudi elisisiseko

 

(Ikhowudi yohlobo, ikhowudi yobungakanani, ikhowudi yobubanzi bangaphakathi [amanani ama-2])

 

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 bebheri 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 yi-5, njenge-04 means d=20mm; 12 means d=60mm, njl. 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 yokuveza ububanzi 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 bangaphakathi obufanayo) luboniswa yinombolo yesithathu ukusuka ngasekunene kwekhowudi esisiseko. Umzekelo, kwiibheri ze-radial kunye ne-radial thrust, u-0 kunye no-1 zibonisa uthotho lokukhanya olongezelelweyo; u-2 ubonisa uthotho lokukhanya; u-3 ubonisa uthotho oluphakathi; u-4 ubonisa uthotho olunzima. Uthelekiso lobungakanani phakathi kothotho luboniswe kumfanekiso ongezantsi. Iibheri ze-Thrust ngaphandle kwe-1 emele uthotho lokukhanya, okuseleyo kunye neebheri ze-radial ziyafana.

 

3) Uthotho lobubanzi bebheri (oko kukuthi, uthotho lotshintsho kububanzi bebheri enesakhiwo esifanayo, ububanzi bangaphakathi kunye nothotho lobubanzi) luboniswa yinombolo yesine ukusuka ekunene kwekhowudi esisiseko. Xa uthelekiso lothotho lobubanzi bebheri kuMfanekiso 13-4 ludweliswe njengoluhlu lwe-0 (uthotho oluqhelekileyo), ikhowudi yoluhlu lobubanzi u-O ayinakumakishwa kwikhowudi yeebheri ezininzi, kodwa kwiibheri zerola ezijikelezayo kunye neebheri zerola ezithambileyo, ikhowudi yoluhlu lobubanzi u-0 kufuneka imakishwe.

 

Iikhowudi zochungechunge lwedayamitha kunye neekhowudi zochungechunge lobubanzi zibizwa ngokuba ziikhowudi zochungechunge lwemilinganiselo.

 

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, iklasi yesi-6X isebenza kuphela kwiibheringi zerola ezithambileyo; Inqanaba lesi-0 linqanaba eliqhelekileyo, elingaphawulwanga kwikhowudi yokuthwala amavili.

 

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 sebheri sisetyenziselwa ukubonisa iinxalenye ezincinci zebheri, eziboniswa ngoonobumba. Umzekelo, u-L usetyenziselwa ukumela indandatho enokuhlukaniswa yebheri enokuhlukaniswa; u-K umele izinto eziqengqelekayo kunye nezinto zekheyiji zebheri, 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 uqhelene nale nxalenye yekhowudi. Ukuze ufumane indlela eneenkcukacha zekhowudi yee-rolling bearings, nceda ujonge kwi-GBT272-93.
