Ulwazi oluyisisekelo lokuthwala

Njengengxenye ebalulekile yemishini yesimanje, amabheringi zisetshenziswa kabanzi. Sonke siyazi futhi sazi okuningi noma okuncane ngakho.

Amabheringingokuvamile kuqukethe indandatho yangaphakathi, indandatho yangaphandle, izinto ezigoqekayo kanye nekheji. Kuma-bearing avaliwe, engeza i-lubricant kanye nama-seal (noma izihlangu). Yilokho okushiwo ama-bearing.

Ngokwezimo zokusebenza zebhereyi, izinhlobo ezahlukene zamabhereyi zingakhethwa ukuze zidlale kangcono umsebenzi webhereyi futhi zandise impilo yenkonzo yebhereyiyi. Kudingeka sicabangele lezi zinto ezilandelayo lapho sikhetha amabhereyiyi:

Umthwalo wemisebe

Umthwalo we-Axial

Izidingo ze-RPM

Ukugijima kwe-radial

Ukugijima kwe-Axial

Izinga lokushisa lokusebenza

Izidingo zomsindo

Isimo sokuthambisa

 

Imodeli yokuthwala ngokuvamile inekhodi yangaphambi kwesikhathi, ikhodi eyisisekelo kanye nekhodi yeposi. Ngokuvamile, ukubizwa kokuthwala kuboniswa kuphela ukubizwa okuyisisekelo. Imodeli eyisisekelo ngokuvamile iqukethe izingxenye ezintathu, ikhodi yohlobo, ikhodi yosayizi kanye nekhodi yobubanzi bangaphakathi. Ikhodi yeposi iwukusebenzisa izinhlamvu nezinombolo ukukhombisa isakhiwo, ukubekezelelana kanye nezidingo ezikhethekile zezinto. Ikhodi yesiqalo isetshenziselwa ukukhombisa izingxenye ezincane zokuthwala, eziboniswa izinhlamvu.

 

1. Igama lekhodi eliyisisekelo

Ikhodi eyisisekelo isetshenziselwa ukukhombisa ububanzi bangaphakathi, uchungechunge lobubanzi, uchungechunge lobubanzi kanye nohlobo lokuthwala, ngokuvamile kufika kumadijithi amahlanu, kanje:

1) Ububanzi bangaphakathi bebhere buboniswa yinombolo yokuqala ukusuka kwesokudla sekhodi eyisisekelo.

Ububanzi bangaphakathi bebhereyitha enobubanzi obujwayelekile bangaphakathi obungu-d=20~480mm ngokuvamile buyi-multiple ka-5, futhi lawa madijithi amabili amelela isilinganiso sobukhulu bobubanzi bangaphakathi bebhereyitha obuhlukaniswe ngo-5, njengo-04 means d=20mm; 12 means d=60mm njalo njalo. Kumabhereyitha anobubanzi bangaphakathi obungu-10mm, 12mm, 15mm kanye no-17mm, amakhodi obubanzi bangaphakathi angama-00, 01, 02 kanye no-03 ngokulandelana. Kumabhereyitha anobubanzi bangaphakathi obungaphansi kuka-10mm nangaphezulu kuka-500mm, indlela yokumelela ububanzi bangaphakathi ichazwe ngenye indlela, sicela ubheke ku-GB/T272-93.

 

2) Uchungechunge lobubanzi bebhereyitha (okungukuthi, uchungechunge lwezinguquko kububanzi bangaphandle kanye nobubanzi bebhereyitha enesakhiwo esifanayo kanye nobubanzi obufanayo bangaphakathi) luboniswa yidijithi yesithathu ngakwesokudla kwekhodi eyisisekelo.

Isibonelo, kuma-radial bearings nama-radial thrust bearings, u-0 no-1 babonisa uchungechunge lokukhanya okwengeziwe; u-2 ubonisa uchungechunge lokukhanya; u-3 ubonisa uchungechunge oluphakathi; u-4 ubonisa uchungechunge olusindayo. Ukuqhathaniswa kosayizi phakathi kochungechunge kuboniswe esithombeni esingezansi. Ngaphandle kochungechunge lokukhanya okwengeziwe no-1, i-thrust bearing ihambisana nokubonakaliswa kwe-radial bearing.

3) Uchungechunge lobubanzi bebhereyitha (okungukuthi, uchungechunge lwezinguquko ebubanzini bebhereyitha enesakhiwo esifanayo, ububanzi bangaphakathi kanye nochungechunge lobubanzi) luboniswa yidijithi yesine ngakwesokudla kwekhodi eyisisekelo.

Uma ukuqhathaniswa kochungechunge lobubanzi bochungechunge lobubanzi be-Figure 13-4 kubhalwe njengochungechunge olungu-0 (uchungechunge olujwayelekile), ikhodi yochungechunge lobubanzi O ayikwazi ukumakwa kukhodi yama-bearings amaningi, kodwa kuma-roller bearings ayindilinga nama-roller bearings athambile, ikhodi yochungechunge lobubanzi olungu-0 kufanele imakwe. Amakhodi ochungechunge lobubanzi namakhodi ochungechunge lobubanzi abizwa ngokuthi amakhodi ochungechunge lobukhulu.

 

4) Ikhodi yohlobo lokuthwala imelelwa yinombolo yesihlanu ukusuka kwesokudla sekhodi eyisisekelo (kuma-roller bearings ayisilinda kanye nama-needle roller bearings, ikhodi iyincwadi).

 

2. Ikhodi yeposi

Ikhodi yeposi yebhereyi iwukusebenzisa izinhlamvu nezinombolo ukukhombisa isakhiwo, ukubekezelelana kanye nezidingo ezikhethekile zezinto ezibonakalayo. Kunokuqukethwe okuningi kwamakhodi eposi, futhi nansi amagama ambalwa ekhodi asetshenziswa kakhulu.

1) Ikhodi yesakhiwo sangaphakathi iwukukhombisa isakhiwo sangaphakathi esihlukile sohlobo olufanayo lokuthwala, olukhonjiswa ngezinhlamvu ezilandelwa ikhodi eyisisekelo. Isibonelo, ama-angler contact ball bearing ane-contact engeli engu-15°, 25° kanye no-40° amelwe ngokulandelana yi-C, AC kanye no-B ukumela umehluko kwisakhiwo sangaphakathi.

2) Izinga lokubekezelelana le-bearing lihlukaniswe ngamamaki ama-2, amamaki ama-4, amamaki ama-5, amamaki ayi-6, amamaki ayi-6X kanye namamaki ayi-0, wonke amamaki ayi-6, kusukela phezulu kuya phansi, futhi amakhodi awo yi-/PZ, /P4, /PS, /P6, /P6X kanye ne-/PO. Phakathi kwamakilasi okubekezelelana, ikilasi lesi-6X lisebenza kuphela kuma-roller bearing athambile; Ibanga lesi-0 liyibanga elijwayelekile, elingamakiwe kukhodi yokuthwala amasondo.

3) Uchungechunge lwe-bearing radial clearance olusetshenziswa kakhulu luhlukaniswe ngeqembu eli-1, amaqembu ama-2, amaqembu angama-0, amaqembu ama-3, amaqembu ama-4 namaqembu ama-5, wonke amaqembu ayi-6, kanti i-radial clearance isukela kwencane kuya kwenkulu. I-Group o clearance iyiqembu le-clearance elisetshenziswa kakhulu, elingamakiwe kukhodi ye-bearing, kanti amanye amaqembu e-clearance amelelwa yi-/CI, /CZ, /C3, /C4 kanye ne-/CS kukhodi ye-bearing.

 

3. Ikhodi yangaphambilini

Isiqalo sebhereyitha sisetshenziselwa ukukhombisa izingxenye ezincane zebhereyitha, ezikhonjiswa ngezinhlamvu. Isibonelo, u-L usetshenziselwa ukumelela indandatho ehlukanisiwe yebhereyitha ehlukanisiwe; u-K umele izakhi ezigoqekayo kanye nezingxenye zekheji zebhereyitha, njll.

 

Kunezinhlobo eziningi zama-rolling bearings ezisetshenziswayo, futhi ama-bearing code ahambisanayo nawo ayinkimbinkimbi kakhulu. Ikhodi eyethulwe ngenhla iyingxenye eyisisekelo nesetshenziswa kakhulu yekhodi yama-bearing, futhi ungayibona futhi uhlole i-bearing esetshenziswa kakhulu uma ujwayelene nale ngxenye yekhodi. Ukuze uthole indlela yekhodi eningiliziwe yama-rolling bearings, sicela ubheke ku-GBT272.
