Linear Motion Bearings: Dzidza nezveZvakanakira zvePlastiki Linear Bearings

Linear motion bearings zvinhu zvakakosha mumhando dzakasiyana dzemakanika masisitimu, zvichigonesa kutsetseka, kwakanyatso kufamba munzira yakatwasuka. Pakati pemhando dzakasiyana dzematsetse ekufamba mabhengi, epurasitiki mutsara mabearings akagamuchira kutariswa kwakapararira nekuda kweakasarudzika ega-kuzora zvivakwa uye kukodzera kwemutoro wakakwira, wepakati uye wakaderera kumhanya kufambisa zvikumbiro.

Kunzwisisa mutsauko wakakosha pakati pepurasitiki nesimbi mutsara mabhengi kwakakosha pakuona iyo yakanyanya kunaka sarudzo kune chaiyo maindasitiri kana michina zvinodiwa. Metal linear mabearings anoshandisa rolling friction uye point yekubata necylindrical shaft, ukuwo maplastic linear bearings achitsamira pakutsvedza uye kubata kumeso. Musiyano wakakosha uyu unobata basa rakakosha pakuona huwandu hwemutoro uye kumhanyisa kukodzera kwemhando yega yega.

Chimwe chezvinonyanya kusiyanisa zvepurasitiki mutsara mabhengi ndeavo ega-lubricating properties. Kusiyana nesimbi mutsara mabhengi, ayo anowanzoda kuwedzera mafuta ekudzikisa kukweshera uye kupfeka, epurasitiki mutsara mabhengi akagadzirwa kuti ashande neashoma kugadzirisa nekuda kweawo ega ega ekuzora. Ichi chimiro hachingodzikisi kudiwa kwekugara kuchizora, asi zvakare chinobatsira kuvandudza kugona kwese uye hupenyu hwesevhisi yekutakura system.

Sarudzo pakati pepurasitiki nesimbi mutsara mabhengi anowanzo kupesvedzerwa nezvinodiwa zvekushandisa, kunyanya maererano nehukuru hwekuremedza uye kumhanya. Metal linear bearings ine rolling friction uye point contact, zvichiita kuti ive yakakodzera kune yakaderera mutoro uye yakakwirira-kumhanya kufambisa zvikumbiro. Plastic linear bearings, kune rumwe rutivi, inokwanisa zvirinani kubata mitoro yakakwira uye yakaderera kusvika pakati nekumhanya kufamba nekuda kwekutsvedza kwadzo uye kubata kwepamusoro.

Mune yakakwirira-mutoro maapplication, kugona kwepurasitiki mutsara mabheji kugovera zvakaenzana mutoro pamusoro penzvimbo yekubatana neiyo cylindrical shaft yakakosha mukana. Iyi ficha inoderedza njodzi yekupfeka nguva isati yakwana uye inova nechokwadi chekushanda kunoenderana kunyangwe pasi pemitoro inorema. Pamusoro pezvo, iyo yakaderedzwa kukweshera kwakabatana nekutsvedza kubata kunobatsira mukushanda kwakapfava uye kuderera kwesimba rekushandisa, zvichiita kuti epurasitiki mutsara fani ive sarudzo inokwezva yezvishandiso uko kushanda nesimba uye kuvimbika kwakakosha.

Imwe mukana wakakosha wepurasitiki mutsara mabhengi ndeyekupokana kwavo nekuora uye kuratidzwa kwemakemikari. Kusiyana nemabhengi esimbi, ayo anogona kukanganiswa nekuora munzvimbo dzakaoma kana kana akaiswa kune mamwe makemikari, mabheji epurasitiki anopa kupikisa kwepamusoro, zvichiita kuti aenderane nehupamhi hwemamiriro ekushanda. Uku kupokana nekuora uye kuratidzwa kwemakemikari kunowedzera kusimba uye kuvimbika kwepurasitiki mutsara mabhengi, kunyanya munzvimbo dzeindasitiri uko zvinhu zvezvakatipoteredza zvinogona kukanganisa kushanda kwemechini zvikamu.

Iko kuita kwakasiyana-siyana kwepurasitiki mutsara mabhengi kunosvika pakuenderana kwavo nemhando dzakasiyana dzeshaft zvinhu, zvinosanganisira simbi isina tsvina, aluminium, uye kunyange zvinyoro zvinyoro zvakaita sepurasitiki kana composite shafts. Iko kuchinjika kweiyi shaft kuenderana kunobvumira hukuru hwekugadzira rusununguko uye inoita kuti mainjiniya agadzirise kutakura masisitimu kune chaiwo maapplication ezvinodiwa, zvichiwedzera kusimudzira kuita kwese uye kushanda kwehurongwa.

Pamusoro pezvakanakira zvemuchina, epurasitiki mutsara mabhengi anopa zvinodhura mhinduro kune akawanda maapplication. Inherent self-lubricating properties inoderedza kudiwa kwekugara uchigadzirisa uye nekuzora, nekudaro ichidzikisa mutengo wese wekushandisa. Pamusoro pezvo, hupenyu hurefu hwesevhisi uye kusimba kwemabhengi epurasitiki kunobatsira kuchengetedza mutengo wenguva refu, zvichiita kuti ive sarudzo yakanaka kune mabhizinesi ari kutsvaga akavimbika uye ehupfumi mitsara yekufamba mhinduro.

Iko kukura kuri kudiwa kweanoshanda uye akavimbika mutsara ekufambisa masisitimu mumaindasitiri akasiyana akafambisa kuenderera mberi nekuvandudzwa kwemapurasitiki emitsetse mabearings. Vagadziri vari kushanda kuti vawedzere zvivakwa zvezvinhu, dhizaini maficha uye maitiro ekuita emabhengi epurasitiki kusangana nekuchinja kwezvinodiwa zvemazuva ano maapplication. Nekuda kweizvozvo, epurasitiki mutsara mabearings ari kuwedzera kukwikwidzana nemasimbi echinyakare, achipa mashandiro akafanana uku achipa mamwe mabhenefiti akadai sekuzvizora uye kuramba kwecorrosion.

Kana uchifunga nezve kusarudzwa kwemutsara wekufamba mabhengi kune chaiyo application, zvakanangana zvinodiwa zvinofanirwa kuongororwa, zvinosanganisira mutoro wekuremerwa, kumhanya, mamiriro ezvakatipoteredza uye kufunga nezvekugadzirisa. Nekunzwisisa zvakanakira mabhenefiti epurasitiki mutsara mabhengi, mainjiniya uye vagadziri vanogona kuita sarudzo dzine ruzivo kukwenenzvera kuita, kushanda nesimba uye hupenyu hurefu hwemasevhisi avo emutsetse ekufambisa.

Muchidimbu, epurasitiki mutsara mabhengi isarudzo yakakosha uye inosiyana-siyana kune akasiyana mitsara yekufambisa zvikumbiro, ichipa ega-kuzora zvivakwa, yakakwirira mutoro, kuramba kutu uye kudhura-kushanda. Sezvo kudiwa kweanoshanda, akavimbika mutsara ekufambisa masisitimu ari kuramba achikura, zvakanakira epurasitiki mutsara mabhengi anovaita sarudzo inomanikidza kune mainjiniya nemabhizinesi ari kutsvaga kukwirisa mashandiro uye hupenyu hwemakina masisitimu avo. Sezvo tekinoroji yemidziyo uye dhizaini yekugadzira ichienderera mberi, epurasitiki mutsara mabhengi achaita basa rinowedzera kukosha mune ramangwana mutsara wekufamba unobereka mhinduro.
