Rolls dzinokosha huremu hwadzo mugoridhe...

Mabhandi anotyaira anoshandiswa mumotokari dzemazuvano anofanirwa kumirisana nekushushikana kunoramba kuchiwedzera kunobva mukushanda muzvikamu zvekutyaira zvakanyanya. Hazvishamisi kuti vagadziri vezvikamu zvavo vari kuedza kuzvigadzirisa kumamiriro ekushandiswa, zvose maererano nekushanda uye kusimba. Chimwe chezvikamu zvinotarisa kushanda kwakarurama kwebhanhire dhiraivha ndeye idler uye idler rollers.

Yakaiswa papi?

Sezvatotaurwa, mhando mbiri dzema rollers dzinoshandiswa mumabhandi madhiraivha: tension uye vatungamiriri. Iwo akaisirwa ese ari maviri mumagasi ekugovera masisitimu uye mumadhiraivha masisitimu einjini mayuniti. Basa rinonyanya kukosha reusimbe uye epakati pulleys ndiyo yakakwana bhandi kutungamira (pasi kana bhandi mashandiro) mune ese madhiraivha modhi uye nenzvimbo yayo yakakwana pamapulleys ari padyo. Yepamusoro-soro idler uye idler rollers inofanirawo kuderedza ruzha rwepasi dhiraivha system, uye kune rumwe rutivi, kusangana nepamusoro zvinodiwa zvekusimba uye kuvimbika. Nokudaro, kushanda kwakarurama kwemutungamiri uye vatungamiri vanofambisa kunoenderana nekugadzirwa kwavo uye zvinhu zvavanoitwa.

Zamu rimwe chete kana kuti kaviri

Single row bhora mabearings anoshandiswa muidle pulleys uye idler pulleys kubva kune vanozivikanwa vanogadzira. Iwo ekupedzisira anozadzwa pafekitari negirisi yemhando yepamusoro yakachinjirwa kushanda pakudziya kwakanyanya. Mumamiriro ezvinhu akaoma zvikuru, kaviri mutsara bhora mabheji akaiswa mukati me rollers. Dzimba dzavo dzinoshandisa zvisimbiso zvakakosha kuchengetedza girisi kubva pakubuda mumarora panguva yekushanda. Zvichienderana nekushandiswa, ma rollers anogona kuva ne polyamide pamusoro yakasimbiswa negirazi fiber kana nzvimbo yesimbi ine anti-corrosion coating. Maererano nenyanzvi, maererano nekugara kwenguva refu, marudzi ose e-rollers anozadzisa zvakakwana basa ravo, kuva chinhu chisingaperi chebhanhire dhiraivha. Kuwedzera, zvisinei, polyamide rollers ine fiberglass inoshandiswa mune dzakadaro masisitimu. Sei? Mhinduro yacho iri nyore: idzo dzakareruka kupfuura dzechinyakare simbi, izvo zvinoderedza huremu hwehurongwa hwese.

Nemagetsi akakodzera

Aya mazwi matatu ndiwo musimboti wekushanda kwakanaka kwemabhandi madhiraivha. Kushanda kwavo kusina dambudziko kunoenderana nebhanhire rakakodzera. Kusawirirana kusina kunaka kunowanzoita kuti bhandi ritsvedze pamasprockets, zvichiita kuti injini ikundikane zvakanyanya nekuda kwemavharuvhu anodhumhana nemapiston. Inofanirawo kuyeukwa kuti bhanhire rinowanzotambanudza nekushandiswa kwezuva nezuva. Kureba kwayo pakarepo kunokonzerwawo nekusiyana kwekushisa. Tichifunga nezvese mamiriro ezvinhu aya, vagadziri vechizvarwa chazvino chevane tensioners uye tensioners vanopa mukana wekugadzirisa iwo zvichienderana nekushanduka kwehurefu hwebhandi. Zvisinei, izvi hazvirevi kuti iwe hauchadi kutarisa ma rollers paunenge uchitarisa mamiriro ebhanhire. Iyo tensioner pulley inofanirwa kutariswa mukuenderana nebhanhire tension uye kugadziridzwa kana zvichidikanwa. Sezvineiwo, otomatiki bhandi tensioners anogadzirisa dambudziko rekwakakodzera bhandi tension. Iyo seti yezvitubu inoshandiswa mavari inovimbisa kugadzikana kwakaringana mukati mehupenyu hwese hwesevhisi. Otomatiki bhandi tension gadziriso inogadziriswa zvese kune yazvino mitoro yehurongwa hwese uye nekuchinja tembiricha. Automatic tensioners ine imwe mukana usingapokane: nekuda kwekushandisa kwavo, kudengenyeka kunokuvadza kunoperekedza kushanda kwebhandi drive kunodzvinyirirwa. Nekuda kweizvozvo, kusimba kweiyo system yese kunowedzera uku ichideredza ruzha.
