Zvinotsanangurwa uye zviyero zve general bronze bushings

Bronze bushings (kana copper alloy bushings) inoshandiswa zvakanyanya mumichina, midziyo yeindasitiri, ngarava, mota nemimwe minda. Ivo vanowanzo shandiswa mukutsvedza mabhengi, kutakura mabhushi, zvivakwa zvekutsigira uye dzimwe nzvimbo. Izvo zvinotsanangurwa uye saizi yebhuronzi bushings inosiyana zvichienderana nezvinodiwa zvekushandisa, zvinhu zvemukati, zvinodikanwa zvekutakura uye zviyero zvekugadzira. Aya anotevera ndiwo akajairwa zvirevo uye saizi masaizi eyakajairwa bronze bushings:

1. Zvakajairwa zvakajairwa uye saizi siyana

Izvo zvinotsanangurwa zvebhuronzi bushings zvinonyanya kusanganisira dhayamita rekunze, dhayamita yemukati uye kureba (kana ukobvu). Mumashandisirwo chaiwo, izvo zvinotsanangurwa uye saizi yebhushi inoda kusarudzwa zvinoenderana nemidziyo yekugadzira zvinodiwa uye mamiriro ekushanda.

(1) dhayamita rekunze (D)

Iyo dhayamita yekunze kazhinji inotangira pa20mm kusvika 500mm. Zvichienderana nehukuru hunodiwa hwemidziyo inoshandiswa, yakakura yekunze dhayamita inogona kushandiswa.

Zvinozivikanwa zvinosanganisira: 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 300mm, 400mm.

(2) dhayamita yemukati (d)

Iyo dhayamita yemukati inoreva hukuru hwebhushi mukati memugodhi, iyo inowanzova duku kudarika dhayamita yekunze kuti ione kuti kujekesa ne shaft kwakakodzera.

Saizi dzakajairika dzemukati dhayamita: 10mm, 20mm, 40mm, 60mm, 100mm, 150mm, 200mm, 250mm.

(3) Hurefu kana ukobvu (L kana H)

Kureba kunowanzo kuve pakati pe20mm ne200mm, uye inogadziriswa zvinoenderana nezvinodiwa zvemidziyo.

Hurefu hwakajairika saizi: 20mm, 50mm, 100mm, 150mm, 200mm.

(4) Kukora kwemadziro (t)

Ukobvu hwemadziro ebhuronzi bushing kazhinji hunoenderana nehupamhi hwemukati uye dhayamita yekunze. Zvakajairwa madziro ukobvu zvirevo ndezvi: 2mm, 4mm, 6mm, 8mm, 10mm.

2. Common size standards

Hukuru hwebhuronzi bushings hunowanzo tevera mamwe maitiro, akadai seGB (Chinese standard), DIN (German standard), ISO (international standard), etc. Heano mamwe maitiro akajairika uye saizi mienzaniso:

(1) GB/T 1231-2003 - Copper alloy kukanda makwenzi

Iyi chiyero inotsanangudza saizi uye dhizaini yebhuronzi bushings uye inoshanda kune yakajairika mechaniki michina.

Somuenzaniso: mukati dhayamita 20mm, kunze dhayamita 40mm, kureba 50mm.

(2) DIN 1850 - Copper alloy bushings

Iyi chiyero inoshanda kune inotsvedza inobereka mabhurashi mumidziyo yemuchina, ine saizi inotangira mukati dhayamita gumi kusvika 500mm uye ukobvu hwemadziro pakati pe2mm ne12mm.

(3) ISO 3547 - Sliding bearings uye bushings

Iyi chiyero inoshanda kune dhizaini uye saizi yekutsvedza mabhengi uye bushings. Saizi dzakajairika dzinosanganisira yemukati dhayamita 20mm, 50mm, 100mm, 150mm, nezvimwe.

3. Common bushing marudzi uye hukuru

Zvichienderana nemhando dzakasiyana dzekugadzira, bronze bushings inogona kuva yemhando dzakasiyana. Common bushing marudzi uye saizi ndeaya anotevera:

(1) Yakajairika denderedzwa bhuronzi bushing

Mukati dhayamita: 10mm kusvika 500mm

Outer dhayamita: Inoenderana dhayamita yemukati, zvakajairika 20mm, 40mm, 60mm, 100mm, 150mm, nezvimwe.

Kureba: Kazhinji kubva 20mm kusvika 200mm

(2) Flange-mhando yebhuronzi bushing

Iyo flange-mhando bushing yakagadzirwa neinobuda mhete (flange) chikamu chekuisa nyore uye chisimbiso.

Mukati dhayamita: 20mm kusvika 300mm

Outer dhayamita: Kazhinji yakakura kupfuura 1.5 times the dhayamita yemukati

Flange ukobvu: Kazhinji 3mm kusvika 10mm

(3) Semi-yakavhurika bhuronzi bushing

Iyo semi-yakavhurika bushing yakagadzirirwa kuve yakavhurika hafu, yakakodzera kune iyo nguva iyo isingaite disassemble zvachose.

Mukati dhayamita: 10mm kusvika 100mm

Outer dhayamita: yakabatana nedhayamita yemukati, kazhinji ine musiyano mudiki.

4. Zvinodiwa zvakakosha uye kugadzirisa

Kana saizi yakajairika isingakodzeri kune zvinodiwa chaizvo, saizi yebhuronzi bushing inogona kugadziridzwa zvinoenderana nezvinodiwa zvekugadzira. Paunenge uchigadzirisa, zvinhu zvakaita sezvinodiwa zvinorema zvemidziyo, nharaunda yekushanda (senge tembiricha, humidity, corrosiveness), uye mamiriro ekuzora anofanirwa kutariswa.

5. Zvakajairwa zvinhu zvinotsanangurwa

Zvinhu zvinowanzoshandiswa pabronze bushings ndezvi:

Aluminium bronze (yakadai seCuAl10Fe5Ni5): inokodzera mutoro wakakwirira uye nzvimbo dzakakwirira dzekudzivirira.

Tin bhuronzi (senge CuSn6Zn3): inokodzera kushorwa uye kushomeka kwakaderera uye kupfeka nharaunda.

Lead bronze (yakadai seCuPb10Sn10): yakakodzera kune yega-kuzora nharaunda ine yakaderera friction coefficient.

6. Reference table

Aya anotevera mamwe akajairika saizi mareferenzi ebronze bushings:

Inner dhayamita (d) Kunze dhayamita (D) Kureba (L) Ukobvu hwemadziro (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

Pfupiso:

Izvo zvinotsanangurwa uye saizi yebhuronzi bushings inosiyana zvichienderana nemamiriro ekushandisa. dhayamita yemukati yakajairika, dhayamita rekunze, kureba, uye ukobvu hwemadziro zviri mukati meimwe danga, uye saizi yakakodzera inogona kusarudzwa zvinoenderana nezvinodiwa. Mumashandisirwo chaiwo, saizi yebhuronzi bushing inoda kutariswa zvichibva pane zvinodiwa dhizaini yemidziyo uye mamiriro ekutakura, uye inogona kugadzirwa kana zvichidikanwa.
