Engine balance shafts

Panguva yekushanda kwe crank mechanism, inertial forces inomuka zvisingadzivisiki. Vanogona kukamurwa kuva pakati nepakati uye vasina kuenzana. Kufamba kwemapistoni kunogadzira kudedera uye ruzha. Kubvisa kusaenzana kweiyo flywheel uye crankshaft haina kukwana zvachose. Naizvozvo, vagadziri vanoisa balancer shafts.

Chinangwa chekuenzanisa shafts

Basa guru rinoitwa kuenzanisa shafts kubvisa kusaenzana uye kuderedza vibration. Dambudziko iri rave kunyanya kukosha kune injini dzine simba. Kuvandudzwa kweinjini dzakakura kudarika 2 litita kwakatungamirira kukudengenyeka kwakasimba. Kuti vabvise dambudziko iri, mainjiniya vakasarudza kushandisa chiyero cheshafts.

Muchiitiko ichi, nzvimbo yemasilinda inofanira kuverengwa. Vagadziri vanoshandisa 3 zvirongwa zvekugadzira.

1. Masilinda anogona kunge ari mundege imwechete.
2. Chirongwa chakasiyana zvachose chinoonekwa sechakajairika, umo maaxes emasilinda anotungamirwa akatarisana.
3. Pane hurongwa hunopa kushandiswa kwev-shaped scheme.

Unhu hwekuenzanisa hunoenderana nenzvimbo yemasilinda. Kuti abvise kusaenzana, kuenzanisa shafts inoshandiswa, iyo inonzi cylindrical rods. Zvinhu izvi zvakaiswa 2 zvidimbu parutivi rumwe norumwe rwe crankshaft. Magiya anoshandiswa kubatanidza zvikamu. Nokudaro, hurongwa hunogona kuenzana. Balance shafts inogona kuderedza zvakanyanya kudedera uye ruzha.

Ainoita

Kubhadhara simba, zvitubu zvinoshandiswa, zviri pamagetsi ekufambisa. Chikonzero chekuwedzera kupfeka kwemanode kunogona kuva mutoro wakawedzerwa unobatanidzwa nekuonekwa kwekusashanda. Mutoro mukuru unowira pabani mabhengi anofambisa kufamba kubva ku crankshaft. Muridzi wemotokari anorayirwa kuti abate nzvimbo yebasa uye kwete kugadzirisa zvikanganiso ivo pachavo.

Dhiraivha mhando

Iyo balancing system inofambiswa neketani kana bhandi rine mazino. Nenzira iyi, shaft vibrations inogona kuderedzwa. Vagadziri vanoisawo chitubu damper muyuniti.

Mabalance shaft akagadzirwa riini?

Pfungwa yekuunza chiyero shafts ndeyeMitsubishi. Iyo itsva yakatanga kushandiswa muna 1976. Iyo tekinoroji yekuvandudza yave yakakurumbira zvikuru, sezvo yakaderedza vibration uye ruzha. Nekubatsirwa kwebhavhari shafts, zvaive zvichikwanisika kuwedzera injini sosi. Panguva ino, injini dzine simba dzakatanga kugadzirwa, iyo yaiva nehuwandu hwemarita maviri. Zvisinei, panguva yekushanda pakava nekudengenyeka kwakasimba. Mune ramangwana, vamwe vagadziri vakasarudza kushandisa budiriro.

Zvimiro zvekutsiva chiyero shafts

Mitoro inoitika panguva yekushanda ine mhedzisiro yakaipa pamabearings. Kutsiva node iyi kunodhura zvakanyanya. Kuti uchengetedze mari, varidzi vemotokari vanomanikidzwa kuparadzanisa bhokisi reekisi. Mapulagi anoshandiswa kuchengetedza tambo dzekubatanidza panguva yekugadzirisa. Mukushaikwa kwemashafu ekuenzanisa, kushanda kweinjini kunokanganiswa. Kudedera uye ruzha zvinoonekwa mumagetsi emagetsi. Chiyero chekusaenzana zvakananga zvinoenderana nehunyanzvi hunhu hwemota. Iwe unogona kuenzanisa iyo system uchishandisa balancer shafts. Kuti uite izvi, zvakakosha kushandura magadzirirwo ejini. Nekudaro, iyi sarudzo inogona kukanganisa nguva yeinjini.

Chikonzero chekuonekwa kwemazwi ekunze anogona kunge ari kusashanda kwezvikamu uye magungano. Nokudaro, muridzi wemotokari anofanira kukurumidza kubata nzvimbo yebasa. Kusagadziriswa kunogona kutungamirira kumatambudziko makuru. Ruzha rwakanyanyisa runogona kukonzerwa nekusakwana kweshaft assembly kana bhandi rakatyoka. Noise uye vibration zvinogona kuitika nekuda kwekusakara mabhengi. Kukanganisa kunokanganisa kushanda kweinjini yese.

Kuti ubvise zvikanganiso, zvinodikanwa kutsiva iyo balancer shafts. Kuti uite izvi, varidzi vemotokari vanofanira kubata nzvimbo yebasa. Tarisiro yekuvandudzwa kukuru haigone kufadza vatyairi. Nokudaro, zvakakosha kuziva zvikonzero zvekuzununguka uye ruzha panguva yakakodzera. Kuti udzivirire maburi kubva mukukuvara kwemagetsi, nyanzvi dzinoshandisa mapulagi. Kushaikwa kwevanotsiva kunogona kutungamira mukusagadzikana kweinjini. Muchiitiko ichi, varidzi vemotokari vanomanikidzwa kubvumirana nekuparara kwakakwana kwechikwata. Zviito zvisina basa zvinogona kutungamira mukurasikirwa kwekuita kweinjini.

Chikonzero chekunze kweruzha musimba remagetsi kungave kukundikana kwezvikamu. Nokudaro, vatyairi vanofanira kuchengeta mitemo inotevera:

1. Aggressive kutyaira maitiro anogona kukonzera chikamu kupfeka.
2. Kuti uderedze mutoro pamagetsi e shaft, zvakakosha kugadzirisa hurongwa panguva yakakodzera.
3. Muridzi wemotokari anofanira kushandura mafuta panguva yakakodzera.
4. Kana zvichidikanwa, bhandi rekutyaira kana cheni ingangoda kutsiviwa. Iyo mitsetse shafts inofanirwa kutenderera pasina mimwe mitoro.
