Mune injini dzinopisa mukati dzine bhanhire dhiraivha yemagetsi ekugovera gasi, zvinodikanwa kuve nechokwadi cheiyo nzvimbo yebhanhire uye kudzikamisa kwayo panguva yekushanda.Aya mabasa anogadziriswa nerubatsiro rwebypass rollers, chinangwa, dhizaini uye kutsiva izvo zvinotsanangurwa zvakadzama munyaya ino.
Chii chinonzi timing bypass roller?
Iyo bypass (rutsigiro, yepakati, parasitic) roller chinhu chinobatsira chebhanhire dhiraivha yegasi kugovera michina (nguva), mahara-inotenderera pulley yediki dhayamita, kuburikidza iyo bhandi renguva rinotenderedzwa pane imwe nzvimbo (kana mapoinzi. )
Iyo nguva bypass roller inogadzirisa akati wandei matambudziko:
• Kushandura rwendo rwebhanhire (kutendeukira kukona inodiwa) maererano nenzvimbo yecamshaft pulleys uye zvakabatanidzwa;
• Kubvisa kudengenyeka kwematavi ebhanhire nehurefu hwahwo hurefu;
• Kugadzikana kwebhanhire renguva panguva yekushanda, kudzivirira resonance phenomena, slippage, nezvimwewo;
• Kuderedzwa kweruzha rwese kwegasi rekugovera michina.
Mune nguva yebhandi dhiraivha, imwe bypass roller inowanzoshandiswa, isingawanzo maviri, asi mazhinji emazuva ano madiki-vhoriyamu injini haana zvikamu izvi zvachose.Panguva imwecheteyo, munhu haafaniri kuvhiringidza iyo bypass roller neimwe nzira yakafanana - tension roller.Iyo tension roller inopa tension inodiwa yebhanhire, ichidzivirira kuti irege kutsvedza uye inoenderana nekuputsika kweinjini, uye inoitawo mabasa eiyo bypass roller munzira.Mune ramangwana, isu tichataura nezve bypass rollers.
Mhando uye dhizaini yenguva bypass rollers
Pasinei nerudzi rwemhando, ose e-bypass rollers akarongwa nenzira imwechete.Nheyo ye roller inotakura, pane mhete yekunze iyo pulley inomanikidzwa.Iyo inotakura ndeye radial (inoona chete mitoro inonangidzirwa paradius), bhora kana roller, inogona kunge yakajairwa mutsara mumwechete kana yakafara kaviri-mutsara.Chiso chekupedzisira chekutakura chinogona kuvharwa nechifukidzo chesimbi kana sleeve kudzivirira kubva kune tsvina, guruva, mvura uye michina yemvura.Iyo pulley yakadhindwa simbi kana yakasimba-yakakanda plastiki, isinga patsanurwe, zvichienderana nerudzi rweinjini, ine hupamhi hwakasiyana uye dhayamita.
Bypass rollers inogona kuva nepulley yakagadzirwa nezvinhu zvakasiyana-siyana:
• Metal - aluminium alloy kana simbi;
•Plasitiki.
Muenzaniso wedhiraivha yenguva ine maviri ebypass rollers emadhayamita akasiyana
Parizvino, mapurasitiki epurasitiki anoshandiswa zvakanyanya, akachipa kupfuura simbi, asi achipa ruzha rushoma uye kuderedza huremu hwese hwehurongwa.Plastiki inopfeka, asi sosi yemazuva ano epurasitiki bypass rollers yakakura, ivo vanowanzo shanda iyo yese nguva yebasa (pakati pemabhandi ekutsiva).
Metal rollers inoshandiswa mumajini ane simba uye akaremerwa zvakanyanya, umo zvakakosha kuve nechokwadi chekuvimbika kweiyo nguva yekutyaira mune ese modes.
Rollers anogona kuve nemapulley ane marudzi akasiyana enzvimbo dzekushanda (mijaho):
• Smooth - nzvimbo yekushanda yakatsetseka, haina zvipingamupinyi;
• Corrugated - nzvimbo yekushanda ine longitudinal grooves yekudzika kwakadzika, iyi dhizaini inoderedza nzvimbo yekusangana yepulley nebhanhire;
• Toothed - nzvimbo yekushanda inotakura mazino akachinjika, iyi inonzi toothed pulley yekusununguka kutenderera.
Panguva imwecheteyo, ma rollers ane pulley yakatsetseka uye yakasvibiswa anogona kugadzirwa neese mapurasitiki nesimbi, uye mazino rollers isimbi chete - simbi kana aluminium alloys.
Toothed bypass roller
Smooth uye grooved rollers akaiswa nenzira yakadai kuti bhanhire rinovafukidza nemusana wayo (smooth) side.Toothed rollers inorongwa nenzira iyo bhanhire rinovafukidza nekushanda kwayo (toothed) rutivi.Kutsiva rollers yeimwe mhando neimwe haigamuchirwi, sezvo izvi zvinoshandura maitiro eiyo system yese uye yakazara nekuputsika kweinjini.
Pakupedzisira, bypass roller pulleys, zvisinei nemhando, inogona kuva neshanduro mbiri:
• Pasina makora ekurovesa;
• Nemakora ekurovesa.
Muchiitiko chechipiri, pulley kune rimwe kana mativi maviri ane makora ehurefu hudiki hunodzivirira bhanhire kubva pakutsvedza.Pamusoro pepurasitiki nesimbi yakatsetseka rollers, iyo collar, sekutonga, inoumba imwechete unit ine pulley, iyo yakadhindwa, yakakandwa kana kutendeuka.Pamusoro pemazino ane mazino, collar pane imwe kana mativi ose maviri inogona kuitwa nenzira yezvindori zvinobviswa, izvo zvinosungirirwa kana roller yakaiswa pajini.
Kuiswa kweiyo bypass roller pane injini kunoitwa nenzira mbiri:
• Yakananga kune bhuroka injini;
• Kushandisa bhuraketi rakasiyana.
Muchiitiko chekutanga, roller ine kutakura kwayo inogara pane imwe nzvimbo yakapiwa pajini injini uye inogadziriswa nebhoti imwe (kuburikidza newasher yekuwedzera dhayamita).Muchiitiko chechipiri, roller inogadziriswa pabhakiti, iyo, zvakare, inosungirirwa pajini injini ine mabhoti maviri kana kupfuura.
Kusarudzwa, kutsiva uye kushanda kwenguva bypass rollers
Bypass rollers inopera panguva yekushanda uye inoda kutsiviwa - oparesheni iyi inoitwa panguva imwe chete nekutsiviwa kwebhandi renguva uye tension roller.Zvose izvi zvikamu, sekutonga, zvinotengeswa mukiti, saka hapana chikonzero chekutarisa zvakasiyana kune roller uye fasteners nokuda kwayo.Paunenge uchitenga bhandi uye rollers, iwe unofanirwa kufunga nezve kurudziro yemugadziri weinjini uye sarudza zvikamu zvemhando dzakakodzera uye nhamba dzekabhuku.
Mune zvimwe zviitiko, roller inogona kukanganisa kana kukundikana zvachose.Kazhinji kazhinji, matambudziko anomuka mukutakura, mune iyo mamiriro ekunze ruzha runoonekwa panguva yekushanda kweinjini.Iyo roller pulley inokonzeresa matambudziko zvakanyanya kushoma kazhinji.Chero zvazvingava, roller inofanira kuchinjwa, nokuda kweizvi unoda kutenga chikamu chitsva maererano nemirairo yemugadziri uye kuita basa maererano nemirayiridzo yekugadzirisa nekugadzirisa motokari iyi.
Panguva yekushanda, iyo bypass roller haidi kuchengetedzwa kwakakosha, kazhinji chikamu ichi chinoshanda zvakajairika mukati menguva yese yebasa uye hachikonzeri matambudziko.
Muviri uye lens yemusoro wemwenje inotaridzwa neayo makuru maitiro uye marudzi emarambi anogona kuiswa.Kuiswa kwezvimwe zvitubu zvemwenje hazvigamuchirwi (nezvisingawanzo kunze), izvi zvinogona kushandura hunhu hwemwenje, uye nekudaro, mota haizopfuure kuongororwa.
Nyaya dzekusarudza, kutsiva uye kushanda kwemwenje wemota
Kuti usarudze maoptics matsva, zvinodikanwa kufunga nezve dhizaini, maficha uye hunhu hwezvigadzirwa zvekare, zvakanakira iwe unofanirwa kutenga mwenje weiyo modhi.Kana isu tichitaura nezve fog lights kana mwenje wekutsvaga uye mwenje wekutsvaga waive usiri pamotokari, saka pano iwe unofanirwa kufunga nezve mukana wekuisa zvigadziriso izvi pamotokari (kuvapo kwemabhuraketi akakodzera, nezvimwewo) uye maitiro avo.
Kunyanya kukoshesa kunofanira kubhadharwa kune kusarudzwa kwemwenje.Nhasi, ivo vanowanzo kuratidzwa mune maviri mavhezheni - ane yakajeka (chena) uye yero chikamu chechiratidzo chekutendeuka.Paunosarudza mwenje weyero weyero, unofanirwa kutenga mwenje une girobhu rakajeka, kana uchisarudza mwenje une chena inotenderera chiratidzo chikamu, iwe unofanirwa kutenga mwenje ine yero (amber) girobhu.
Kutsiviwa kwemwenje kunoitwa maererano nemirayiridzo yekushanda uye kugadziriswa kwemotokari.Mushure mekutsiva, zvinodikanwa kugadzirisa mavhenekeri maererano nemirayiridzo yakafanana.Muchiitiko chakareruka, basa iri rinoitwa pachishandiswa chidzitiro - ndege yakatwasuka ine micherechedzo painongedzerwa mwenje, madziro, gonhi regaraji, fenzi, nezvimwe zvinogona kuita sechidzitiro.
Kune yeEuropean-style yakaderera beam (ine asymmetric beam), zvinodikanwa kuve nechokwadi kuti muganho wepamusoro weiyo yakachinjika chikamu chechiedza chinowanikwa pazasi pepakati pemwenje.Kuti uone chinhambwe ichi, unogona kushandisa fomura inotevera:
h = H–(14×L×H)/1000000
uko h iri chinhambwe kubva paaxis yemwenje yemwenje kusvika kumuganhu wepamusoro wenzvimbo, H chinhambwe kubva munzira yemugwagwa kusvika pakati pemwenje, L chinhambwe kubva pamotokari kuenda kuchiratidziro, chiyero chekuyera mm.
Kuti ugadzirise, zvakakosha kuisa motokari kure nemamita 5-8 kubva pachiratidziro, kukosha h kunofanira kurara muhuwandu hwe 35-100 mm, zvichienderana nekukwirira kwemotokari uye nzvimbo yezviedza zvayo.
Kune iyo yakakwirira danda, zvinodikanwa kuve nechokwadi kuti pakati penzvimbo dzemwenje inorara inenge hafu yechinhambwe kubva kune optical axis yemusoro wemwenje uye muganho weiyo yakaderera danda mwenje nzvimbo.Zvakare, iwo optical axes emwenje wembatya anofanirwa kunangidzirwa kumberi, pasina kutsauka kumativi.
Nechisarudzo chakanaka uye kugadziriswa kwemwenje, motokari ichagamuchira michina yekuvhenekera yepamusoro inosangana nezvinodiwa zvehutano uye inochengetedza kuchengeteka mumugwagwa paunenge uchityaira murima.
