Iinkcukacha kunye nemilinganiselo ye-bronze bushings ngokubanzi

I-Bronze bushings (okanye i-copper alloy bushings) isetyenziswa ngokubanzi koomatshini, izixhobo zoshishino, iinqanawa, iimoto kunye nezinye iindawo. Zihlala zisetyenziselwa ukutyibilika kweebheringi, ukuthwala amahlathi, izakhiwo zokuxhasa kunye nezinye iindawo. Inkcazo kunye nobukhulu be-bronze bushings iyahluka ngokuxhomekeka kwiimfuno zesicelo, iimpawu eziphathekayo, iimfuno zomthwalo kunye nemigangatho yokuvelisa. Oku kulandelayo zizinto eziqhelekileyo kunye nobukhulu beentlobo ze-bronze bushings ngokubanzi:

1. Iimpawu eziqhelekileyo kunye nobukhulu bemilinganiselo

Ukucaciswa kwe-bronze bushings ikakhulu kubandakanya i-diameter yangaphandle, i-diameter yangaphakathi kunye nobude (okanye ubukhulu). Kwizicelo ezithile, ukucaciswa kunye nobukhulu be-bushings kufuneka kukhethwe ngokweemfuno zoyilo lwezixhobo kunye neemeko zokusebenza.

(1) Idayimitha yangaphandle (D)

I-diameter yangaphandle idla ngokusukela kwi-20mm ukuya kuma-500mm. Ngokuxhomekeke kwiimfuno zobukhulu bezixhobo ezisetyenzisiweyo, i-diameter yangaphandle enkulu ingasetyenziswa.

Iimpawu eziqhelekileyo ziquka: 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 300mm, 400mm.

(2) Idayimitha yangaphakathi (d)

I-diameter yangaphakathi ibhekisela kubukhulu be-bushing ngaphakathi kwe-shaft, edla ngokuba yincinci kunobubanzi obungaphandle ukuze kuqinisekiswe ukuba ukucocwa kunye ne-shaft kufanelekile.

Ubungakanani obuqhelekileyo bedayamitha yangaphakathi: 10mm, 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 250mm.

(3) Ubude okanye ubukhulu (L okanye H)

Ubude ngokuqhelekileyo buphakathi kwe-20mm kunye ne-200mm, kwaye ihlengahlengiswa ngokweemfuno zezixhobo.

Ubukhulu obuqhelekileyo bobude: 20mm, 50mm, 100mm, 150mm, 200mm.

(4) Ubukhulu bodonga (t)

Ubunzima bodonga lwe-bronze bushing ngokuqhelekileyo luhambelana nobubanzi obungaphakathi kunye nobubanzi bangaphandle. Imilinganiselo yobukhulu bodonga oluqhelekileyo zezi: 2mm, 4mm, 6mm, 8mm, 10mm.

2. Imilinganiselo yobungakanani obuqhelekileyo

Ubungakanani be-bronze bushings buhlala bulandela imigangatho ethile, njenge-GB (umgangatho waseTshayina), i-DIN (umgangatho waseJamani), i-ISO (umgangatho wamazwe ngamazwe), njl. Nantsi imigangatho eqhelekileyo kunye nemizekelo yobukhulu:

(1) GB/T 1231-2003 - I-alloy yobhedu yokuphosa amahlahla

Lo mgangatho uchaza ubungakanani kunye noyilo lweebhubhu zobhedu kwaye zisebenza kwisixhobo somatshini ngokubanzi.

Umzekelo: ububanzi bangaphakathi 20mm, ngaphandle ububanzi 40mm, ubude 50mm.

(2) I-DIN 1850 - i-alloy bushings yobhedu

Lo mgangatho usebenza kwi-sliding bearing bushings kwisixhobo somatshini, ezinobukhulu obususela kwi-diameter yangaphakathi eyi-10mm ukuya kwi-500mm kunye nobukhulu bodonga phakathi kwe-2mm kunye ne-12mm.

(3) ISO 3547 - Iibheringi zokutyibilika kunye namatyholo

Lo mgangatho usebenza kuyilo kunye nobukhulu beebheringi ze-sliding kunye ne-bushings. Ubukhulu obuqhelekileyo bubandakanya ububanzi bangaphakathi 20mm, 50mm, 100mm, 150mm, njl.

3. Iintlobo ze-bushing eziqhelekileyo kunye nobukhulu

Ngokuxhomekeke kwiimfuno zoyilo ezahlukeneyo, i-bronze bushings ingaba yeentlobo ezahlukeneyo. Iindidi eziqhelekileyo ze-bushing kunye nobukhulu zimi ngolu hlobo lulandelayo:

(1) Ubhedu olungqukuva oluqhelekileyo

I-diameter yangaphakathi: 10mm ukuya kwi-500mm

I-diameter yangaphandle: Ngokuhambelana nobubanzi bangaphakathi, eziqhelekileyo ziyi-20mm, 40mm, 60mm, 100mm, 150mm, njl.

Ubude: Ngokuqhelekileyo ukusuka kwi-20mm ukuya kwi-200mm

(2) I-Flange-type bronze bushing

I-bushing yohlobo lwe-flange yenzelwe ngendandatho ephumayo (i-flange) inxalenye yokufakela lula kunye nokutywinwa.

I-diameter yangaphakathi: 20mm ukuya kwi-300mm

Idayamitha yangaphandle: Idla ngokuba nkulu kune-1.5 yamaxesha edayamitha yangaphakathi

Ubukhulu becala: Ngokuqhelekileyo yi-3mm ukuya kwi-10mm

(3) Ibhulonzi evulekileyo yobhedu

I-semi-open bushing yenzelwe ukuba ivuleke isiqingatha, ilungele iimeko apho kungenakulungelelaniswa ngokupheleleyo.

I-diameter yangaphakathi: 10mm ukuya kwi-100mm

Idayimitha yangaphandle: ehambelana nobubanzi obungaphakathi, ngokuqhelekileyo kunye nomahluko omncinci.

4. Iimfuno ezikhethekileyo kunye nokwenza ngokwezifiso

Ukuba ubungakanani obuqhelekileyo abufanelekanga kwiimfuno ezithile, ubukhulu be-bronze bushing bungenziwa ngokwezifiso ngokweemfuno zokuyila. Xa uhlengahlengisa, izinto ezinje ngeemfuno zomthwalo wesixhobo, indawo yokusebenza (efana nobushushu, ukufuma, ukudleka), kunye neemeko zokuthambisa kufuneka ziqwalaselwe.

5. Iinkcukacha zezinto eziqhelekileyo

Izinto eziqhelekileyo ezisetyenziselwa i-bronze bushings zezi:

I-Aluminiyam yobhedu (efana neCuAl10Fe5Ni5): ifanelekile kumthwalo ophezulu kunye neendawo zokumelana nokunxiba okuphezulu.

Ibronzi ye-tin (efana neCuSn6Zn3): ifanelekile ukuxhathisa i-corrosion kunye ne-friction ephantsi kunye neendawo zokunxiba.

Ibronzi ekhokelayo (efana neCuPb10Sn10): ilungele indawo zokuzithambisa kunye ne-coefficient ephantsi ye-friction.

6. Itheyibhile yeReferensi

Oku kulandelayo zezinye iireferensi zobungakanani obuqhelekileyo kwi-bronze bushings:

Idayamitha yangaphakathi (d) Idayamitha yangaphandle (D) Ubude (L) Ubukhulu bodonga (t)

20 mm 40 mm 50 mm 10 mm

40 mm 60 mm 80 mm 10 mm

100 mm 120 mm 100 mm 10 mm

150 mm 170 mm 150 mm 10 mm

200 mm 250 mm 200 mm 10 mm

Isishwankathelo:

Inkcazo kunye nobukhulu be-bronze bushings iyahluka ngokuxhomekeka kwimeko yesicelo. I-diameter eqhelekileyo yangaphakathi, i-diameter yangaphandle, ubude, kunye nobukhulu bodonga buphakathi koluhlu oluthile, kwaye ubungakanani obufanelekileyo bunokukhethwa ngokweemfuno. Kwizicelo zangempela, ubukhulu be-bronze bushing kufuneka bumiselwe ngokusekelwe kwiimfuno zoyilo lwezixhobo kunye neemeko zomthwalo, kwaye zingenziwa ngokwezifiso xa kuyimfuneko.
