Imininingwane kanye nobukhulu bezihlahla zethusi ezijwayelekile

Ama-bronze bushings (noma ama-copper alloy bushings) asetshenziswa kakhulu emishinini, emishinini yezimboni, emikhunjini, ezimotweni nakweminye imikhakha. Zivame ukusetshenziselwa ama-sliding bearings, ama-bushings okuthwala, izakhiwo zokusekela nezinye izindawo. Ukucaciswa nobukhulu be-bronze bushings kuyahlukahluka kuye ngezidingo zohlelo lokusebenza, izakhiwo zezinto ezibonakalayo, izidingo zomthwalo kanye namazinga okukhiqiza. Okulandelayo ukucaciswa okujwayelekile kanye nobubanzi bosayizi wezihlahla ezijwayelekile zethusi:

1. Ukucaciswa okujwayelekile kanye nobubanzi besayizi

Imininingwane ye-bronze bushings ikakhulukazi ihlanganisa ububanzi obungaphandle, ububanzi bangaphakathi nobude (noma ukujiya). Kuzicelo ezithile, ukucaciswa nobukhulu bezihlahla kufanele kukhethwe ngokuya ngezidingo zokwakhiwa kwemishini kanye nezimo zokusebenza.

(1) Ububanzi bangaphandle (D)

Ububanzi bangaphandle ngokuvamile busukela ku-20mm kuye ku-500mm. Kuye ngezidingo zobukhulu bemishini esetshenzisiwe, ububanzi obungaphandle obukhudlwana bungasetshenziswa.

Imininingwane ejwayelekile ihlanganisa: 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 300mm, 400mm.

(2) Ububanzi bangaphakathi (d)

I-diameter yangaphakathi ibhekisela kusayizi we-bushing ngaphakathi kwe-shaft, ngokuvamile encane kunobubanzi obungaphandle ukuze kuqinisekiswe ukuthi ukucaciswa nge-shaft kufanelekile.

Amasayizi ajwayelekile obubanzi bangaphakathi: 10mm, 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 250mm.

(3) Ubude noma ukujiya (L noma H)

Ubude ngokuvamile buphakathi kuka-20mm no-200mm, futhi bulungiswa ngokuvumelana nezidingo zemishini.

Osayizi abajwayelekile bobude: 20mm, 50mm, 100mm, 150mm, 200mm.

(4) Ukujiya kodonga (t)

Ubukhulu bodonga lwe-bronze bushing ngokuvamile buhlobene nobubanzi obungaphakathi nobubanzi bangaphandle. Ukucaciswa okujwayelekile kodonga yilezi: 2mm, 4mm, 6mm, 8mm, 10mm.

2. Izindinganiso zosayizi ovamile

Usayizi we-bronze bushings ngokuvamile ulandela izindinganiso ezithile, njenge-GB (izinga lesiShayina), i-DIN (izinga lesiJalimane), i-ISO (izinga lamazwe ngamazwe), njll. Nazi ezinye izilinganiso ezivamile nezibonelo zosayizi:

(1) GB/T 1231-2003 - I-Copper alloy casting bushings

Leli zinga licacisa usayizi nokuklanywa kwezihlahla zethusi futhi lisebenza kumishini evamile.

Isibonelo: ububanzi obungaphakathi 20mm, ububanzi obungaphandle bungama-40mm, ubude obungama-50mm.

(2) I-DIN 1850 - I-Copper alloy bushings

Leli zinga lisebenza kuma-sliding bearing bushings emishinini engumshini, enosayizi osuka ku-diameter yangaphakathi engu-10mm ukuya ku-500mm nogqinsi lwezindonga phakathi kuka-2mm no-12mm.

(3) ISO 3547 - Ama-sliding bearings kanye nezihlahla

Leli zinga lisebenza ekwakhiweni nakusayizi wama-sliding bearings nama-bushings. Osayizi abajwayelekile bafaka phakathi ububanzi obuyi-20mm, 50mm, 100mm, 150mm, njll.

3. Izinhlobo ezivamile ze-bushing namasayizi

Ngokuya ngezidingo ezahlukene zokuklama, ama-bronze bushings angaba izinhlobo ezahlukene. Izinhlobo ezivamile ze-bushing nosayizi zimi kanje:

(1) Isihlahla sethusi esiyindilinga esivamile

Ububanzi bangaphakathi: 10mm kuya ku-500mm

Ububanzi bangaphandle: Ngokuhambisana nobubanzi obungaphakathi, obuvamile bungama-20mm, 40mm, 60mm, 100mm, 150mm, njll.

Ubude: Ngokuvamile kusuka ku-20mm kuya ku-200mm

(2) Isihlahla se-bronze sohlobo lwe-flange

I-flange-type bushing yakhelwe ngengxenye yendandatho ephumayo (i-flange) ukuze ifakwe kalula futhi ivalwe.

Ububanzi bangaphakathi: 20mm kuya ku-300mm

Idayamitha yangaphandle: Imvamisa inkulu kune-diameter yangaphakathi izikhathi ezingu-1.5

Ubukhulu be-Flange: Ngokuvamile 3mm kuya ku-10mm

(3) Ibhulashi lethusi elivulekile kancane

I-semi-open bushing yakhelwe ukuthi ivuleke uhhafu, ilungele izikhathi lapho kungafanele khona ukuhlakazeka ngokuphelele.

Ububanzi bangaphakathi: 10mm kuya ku-100mm

Ububanzi bangaphandle: obuhlobene nobubanzi obungaphakathi, ngokuvamile obunomehluko omncane.

4. Izidingo ezikhethekile kanye nokwenza ngokwezifiso

Uma usayizi ojwayelekile awufanele izidingo ezithile, ubukhulu be-bronze bushing bungenziwa ngokwezifiso ngokuvumelana nezidingo zokuklama. Lapho kwenziwa ngendlela oyifisayo, izici ezifana nezidingo zomthwalo wempahla, indawo yokusebenza (njengezinga lokushisa, umswakama, ukugqwala), nezimo zokugcoba zidinga ukucatshangelwa.

5. Ukucaciswa kwezinto ezijwayelekile

Izinto ezivame ukusetshenziselwa i-bronze bushings yilezi:

I-aluminium bronze (efana ne-CuAl10Fe5Ni5): ifanele ukulayisha okuphezulu nezimo eziphakeme zokumelana nokugqokwa.

Ithusi likathayela (njengeCuSn6Zn3): lilungele ukumelana nokugqwala kanye nokungqubuzana okuphansi kanye nezindawo zokugqoka.

I-bronze eholayo (efana ne-CuPb10Sn10): ifanele izindawo zokuzithambisa ezine-coefficient ephansi yokungqubuzana.

6. Ithebula lereferensi

Okulandelayo ezinye izinkomba zosayizi ezijwayelekile ze-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

Isifinyezo:

Ukucaciswa nosayizi be-bronze bushings kuyahlukahluka kuye ngesimo sohlelo lokusebenza. Ububanzi obujwayelekile bangaphakathi, ububanzi bangaphandle, ubude, nokuqina kodonga kungaphakathi kwebanga elithile, futhi usayizi ofanele bungakhethwa kuye ngokwezidingo. Kuzicelo zangempela, usayizi we-bronze bushing udinga ukunqunywa ngokusekelwe ezidingweni zokuklama imishini kanye nezimo zokulayisha, futhi kungenziwa ngokwezifiso uma kunesidingo.
