Zvimiro zvemaitiro emabhengi emhangura

Kutakura kwemhangura chinhu chakakosha chinoshandiswa zvakanyanya mumichina yemagetsi. Inonyanya kushandiswa kutakura kutenderera kweshaft, kuderedza kupesana, kupa lubrication uye kutsigirwa. Inowanzo gadzirwa nemhangura yemhangura (yakadai sealuminium bronze, tin bronze, nezvimwewo), ine zvakanaka kupfeka kusagadzikana, corrosion resistance uye yakakwirira mutoro. Mamiriro ekuumbwa kwemhangura anotakura anonyanya kusanganisira zvinotevera zvinhu:

1. Zvinhu

Mhangura inotakura kazhinji inogadzirwa nemhangura alloy, iyo yakajairika ndeiyi:

Aluminium bronze: ine yakanaka kupfeka kuramba, corrosion resistance uye yakakwirira tembiricha kuramba, inokodzera yakakwirira mitoro mamiriro.

Tin bronze: ine yakanaka kupfeka kuramba, corrosion resistance uye simba rakasimba, inokodzera zvepakati nepamusoro mitoro mamiriro.

Lead bronze: inokodzera yakaderera kumhanya, inorema mutoro uye yakakura vibration nguva, nekuti ine self-lubrication.

2. Kupfeka-resistant layer uye dhizaini yekugadzira

Mhangura inotakura kazhinji inosanganisira yakawanda-layer chimiro, kazhinji ine yakakwira kuoma-inodzivirira layer uye yakapfava base layer:

Kupfeka-resistant layer: Iyi dhizaini inowanzo umbwa nemhangura alloy pachayo kana dhizaini yepasi ine zvimwe zvinhu zvealloying, ine yakasimba kupfeka kuramba uye corrosion resistance.

Matrix layer: Iyo matrix yemhangura inobereka icopper alloy, ine yakanaka plastiki uye yakaderera friction coefficient.

3. Lubrication groove design

Iyo yepamusoro yemhangura inotakura kazhinji inogadzirwa ine lubrication grooves (inonziwo mafuta grooves kana oiri nzira) yekuchengetedza uye kugovera mafuta ekuzora. Dhizaini yeiyi grooves inogona kunyatso kudzikisa kupokana, kuderedza tembiricha, uye kugadzirisa lubrication maitiro, kuwedzera hupenyu hwesevhisi yekubereka.

4. Anti-seizure design

Kutakura kunowanzo kugadzirwa neimwe "gap" kuti ive nechokwadi chekuti pane nzvimbo yakakwana panguva yekuisa kuitira kuti mafuta ekuzora apinde pakati pekutakura uye shaft kuumba firimu remafuta kudzivirira kutarisana kwesimbi yakananga, nekudaro kuderedza kupera uye kubata.

5. Kutakura-kutakura simba uye elasticity

Zvinhu zvemhangura yemhangura ine simba rakanaka rekutakura uye inogona kuchengetedza kukwana kwakakwana uye kusimba kana ichimhanya pasi pemutoro mukuru, iyo inonyanya kukosha kune mutoro wemashizha makuru.

6. Kupisa kunopisa simba

Iyo mhangura yemhangura ine yakanaka thermal conductivity, iyo inobatsira kutakura kuti ibudirire kupisa kupisa uye kuchengetedza tembiricha yakakodzera kana ichimhanya nekukurumidza kudzivirira kukuvadzwa kwekutakura nekuda kwekupisa.

7. Corrosion resistance

Copper alloys ane natural corrosion resistance, kunyanya kune ma mechanic parts anoshandiswa mumvura kana makemikari nharaunda. Nekuda kwekugadzikana kwekemikari yemhangura, mabhengi anogona kumira munzvimbo dzakaoma dzekushanda.

8. Self-lubrication (pasi pemamwe madhizaini akakosha)

Mamwe mabhengi emhangura alloy akagadzirwawo kuti azvizodze, kuburikidza neakakosha maumbirwo emidziyo kana kuwedzera kwezvimedu zvidiki zvekuzora kuti uwane mhedzisiro yekuzora kwenguva refu uye kuderedza kuvimba nemafuta ekunze.

Summary

Mamiriro ekuumbwa kwemabhengi emhangura anonyanya kuratidzwa mune yavo zvinhu (copper alloy), kupfeka kuramba, lubricity yakanaka, inonzwisisika kupisa kupisa dhizaini uye corrosion resistance. Kuburikidza nemagadzirirwo aya, anogona kuderedza kupokana, kuwedzera hupenyu hwesevhisi uye kupa kushanda kwakagadzikana mumidziyo yakasiyana siyana yemaindasitiri.
