Ongororo yekutakura zvinhu kupatsanurwa uye kuita zvinodiwa

Sechinhu chakakosha mukushanda kwemakanika, kusarudzwa kwezvinhu zvema bearingsinokanganisa zvakananga kuita kwayo. Mishonga inoshandiswa inosiyana kubva kune imwe nzvimbo kuenda kune imwe. Izvi zvinotevera kuongororwa kwakadzama kwechikamu uye kuita zvinodiwa zvezvinowanzo shandiswa kutakura zvinhu.

 

1. Metal zvinhu

Kutakura alloy: kusanganisira tin matrix uye lead matrix, ine yakanakisa mashandiro akazara, akakodzera kune yakakwirira mitoro mamiriro, asi mutengo wakakwira.

Copper alloys: inosanganisira tin bronze, aluminium bronze uye lead bronze, inokodzera nharaunda dzekushanda pasi pekumhanya kwakasiyana uye mamiriro ekutakura.

 

Cast iron: inokodzera kuremerwa mutoro, yakaderera kumhanya mamiriro.

 

2. Porous metal zvinhu

Nyaya iyi inosiirwa kubva muhupfu hwesimbi hwakasiyana uye inozvizora. Inokodzera mitoro yakatsetseka uye isina kuvhunduka uye madiki kusvika epakati kumhanya mamiriro.

 

3. Zvinhu zvisiri zvesimbi

Inonyanya kusanganisira mapurasitiki, rabha uye nylon, iyo ine maitiro ehushoma coefficient of friction, kupfeka kusaga uye kusagadzikana kwekuora, asi ine yakaderera kutakura uye iri nyore kukanganiswa nekupisa.

 

Kutakura zvinhu kuita zvinodiwa:

Kupindirana kweFriction: Inodzivirira kunamatira uye muganho lubrication, iyo inopesvedzerwa nezvakati wandei zvinhu, zvinosanganisira kuumbwa, mafuta ekuzora, uye microstructure.

Embeddedness: Inodzivirira zvimedu zvakaoma kupinda uye kukonzera mavanga kana mabrasion.

Kumhanya-mukati: Inoderedza kukweshera uye chiyero chekupfeka nekudzikisira zvikanganiso zvemuchina uye pamusoro roughness parameter value.

Friction kutevedzera: Iyo elastoplastic deformation yechinhu inotsiva kushomeka kwekutanga kukwana uye shaft kuchinjika.

 

Abrasion resistance: Kukwanisa kuramba kupfeka uye kubvaruka.

Kuramba kuneta: Kugona kuramba kukuvara kwekuneta pasi pemitoro yecyclic.

Corrosion resistance: Kugona kuramba kuonda.

Cavitation kuramba: Kugona kuramba cavitation kupfeka.

Compressive simba: Kugona kumira-imwe nzira mitoro pasina deformation.

Dimensional kugadzikana: Kugona kuchengetedza dimensional kurongeka pamusoro pekushandiswa kwenguva refu.

Anti-Ngura: Iine yakanaka anti-rust performance.

Maitiro ekuita: Chinja kune izvo zvinodikanwa zveakawanda kupisa uye kutonhora kugadzirisa maitiro, kusanganisira kuumbwa, processability uye kupisa kupisa kuita.

Izvo zviri pamusoro apa ongororo yakazara yekugadzika kwezvinhu zvinowanzoshandiswa zvinotakura uye zvavanoda kuita.
