Radial spherical plain bearings

Radial spherical plain bearings zvinhu zvakakosha mumhando dzakasiyana dzemaindasitiri ekushandisa, ichipa pivot rutsigiro rwekutenderera shafts uye zvimwe zvinofamba zvikamu. Yakagadzirirwa kutakura radial, axial kana mitoro yakasanganiswa, aya mabhengi anoshandiswa zvakanyanya mumichina, masisitimu emotokari uye midziyo yemhepo. Kunzwisisa kupatsanurwa kweradial spherical bearings kwakakosha pakusarudza mhando chaiyo yeimwe application uye kuve nechokwadi chekushanda kwakakwana uye hupenyu hwesevhisi.

Kupatsanurwa kweradial spherical bearings

Radial spherical plain bearings inogona kuverengerwa zvichibva pane akati wandei akakosha zvinhu, kusanganisira dhizaini yavo, zviwanikwa uye maitiro ekuita. Nekunzwisisa aya maratidziro, mainjiniya uye nyanzvi dzekugadzirisa vanogona kuita sarudzo dzine ruzivo pakusarudza mabheya ekushandisa kwakasiyana.

1. Kuronga kwekugadzira

Radial spherical plain bearings inowanikwa mumhando dzakasiyana siyana kuti isangane nemutoro wakasiyana uye zvinodiwa zvekufamba. Magadzirirwo akanyanya zvinosanganisira zvinotevera:

- Simbi pasimbi: Mabearings aya ane ring yemukati ine convex yekunze uye mhete yekunze ine concave yemukati pamusoro, ese akagadzirwa nesimbi yakaoma. Izvo zvakakodzera kune zvinorema-basa zvikumbiro uye zvinogona kumira inorema radial uye kuvhunduka mitoro.

- Steel Bronze: Muchigadziro ichi, mhete yemukati inogadzirwa nesimbi yakaoma, nepo mhete yekunze yakashongedzwa nedhizaini yebhuronzi. Iyi dhizaini inopa yakanaka kupfeka kuramba uye inokodzera maapplication ane mwero mitoro uye oscillatory mafambiro.

- Simbi-PTFE inoumbwa: Mhete yemukati yemabhengi aya yakagadzirwa nesimbi yakaoma uye mhete yekunze yakashongedzwa nePTFE (polytetrafluoroethylene) inoumbwa. Ivo vanopa yakaderera kukweshera, kuchengetedza-yemahara kushanda uye kwakakodzera maapplication uko lubrication yakaoma kana isingaite.

- Steel-PTFE Fabric: Zvakafanana nemagadzirirwo akaumbwa, aya mabhengi ane mhete yemukati yakagadzirwa nesimbi yakaoma uye mhete yekunze yakavharwa nePTFE machira. Ivo vane hukuru hwekutakura mutoro uye vanokodzera maapplication ane inorema radial mitoro uye shoma lubrication.

2. Kuronga zvinhu

Radial spherical plain bearings inowanikwa mumhando dzakasiyana dzezvinhu zvakasanganiswa kuti zvienderane nemamiriro akasiyana ekushanda uye zvakatipoteredza. Kusarudzwa kwezvinhu kunogona kukanganisa zvakanyanya kubereka kuita uye hupenyu hwebasa. Common material classifications zvinosanganisira:

- Simbi: Bearings musimbi-pa-simbi kana simbi-on-bronze magadzirirwo anogadzirwa kubva kusimbi yakaoma kune yakakwirira simba uye kusimba. Simbi mabearings akakodzera kushandiswa nemitoro inorema uye yakaoma kushanda mamiriro.

- PTFE (polytetrafluoroethylene): Mabearings ane PTFE composite kana PTFE machira emucheka anopa kukweshera kwakaderera, kuzvidzora zvivakwa uye kuramba kukora uye kupfeka. Aya mabearings akanakira maapplication anoda kuchengetedzwa-yemahara kushanda uye yakawedzerwa hupenyu hwesevhisi.

-Bronze: Bronze-lined mabearings ane zvakanaka kupfeka kuramba uye anogona kumira zvine mwero mitoro uye oscillatory mafambiro. Iwo akakodzera maapplication anoda kuenzana mutoro wekugona uye kupfeka kuramba.

3. Kurongwa kwemaitiro

Radial spherical plain bearings inoiswawo zvinoenderana nemaitiro avo ekuita, kusanganisira kutakura mutoro, kugona kusarongeka uye tembiricha yekushanda. Aya maratidziro ekuita anobatsira pakusarudza iro rakakodzera fani kune chaiyo application:

- Mutoro wekutakura huwandu: Iyo yakayerwa yakakura radial uye axial mutoro wekutakura huwandu hwemabheri inotaridza kukodzera kwavo kune akasiyana maapplication. High-performance bearings inogona kutsungirira mitoro inorema uye mitoro yekuvhundutsa pasina kutadza nguva isati yakwana.

- Misalignment Kugona: Mamwe mabhengi akagadzirwa kuti agadzirise kusarongeka pakati pe shaft neimba, zvichibvumira kushanda zvakanaka kunyangwe mumashandisirwo ane shaft deflection kana kusarongeka.

- Operating Temperature Range: Bearings yakatarwa kune yakanyanya uye shoma tembiricha yekushanda, kuve nechokwadi chekuita kwakavimbika pasi pemamiriro ekushisa kwakanyanya.

Kushandiswa kweradial spherical bearings

Radial spherical plain bearings inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana nemidziyo, kusanganisira:

- Michina: Aya mabhengi anoshandiswa mumakina akasiyana senge midziyo yekurima, michina yekuvaka nemichina yemaindasitiri kutsigira shaft inotenderera uye zvikamu zvinofamba.

-Motokari masisitimu: Radial spherical plain bearings zvinhu zvakakosha mumotokari kumiswa masisitimu, kutungamira zvinongedzo uye zvimwe zvakakosha zvemotokari kunyorera.

- Aerospace Equipment: Aya mabheji anoshandiswa mugiya rekumhara ndege, masisitimu ekudzora ndege uye mamwe maapplication emuchadenga uko kushanda kwepamusoro uye kuvimbika kwakakosha.

Muchidimbu, kurongeka kwema radial spherical bearings kwakakosha kuti unzwisise dhizaini yavo, zvinhu uye maitiro ekuita. Nekutarisisa aya masisitimu, mainjiniya uye nyanzvi dzekugadzirisa vanogona kusarudza iyo yakanyanya kufanira kutakura kune chaiyo application, kuve nechokwadi chekuita kwakanyanya, hupenyu hurefu uye kuvimbika. Kunyangwe kutsigira mitoro inorema mumachina emaindasitiri kana kupa kushanda kwakatsetseka mumotokari uye aerospace masisitimu, radial spherical bearings inoita basa rakakosha mumhando dzakasiyana dzekushandisa, zvichiita kuti dzive dzakakosha muinjiniya uye tekinoroji. s chikamu.
