Muindasitiri yemotokari, kururama kwezvikamu kunokanganisa zvakananga mashandiro, kuchengetedzeka uye kuvimbika kwemotokari yese. Kubva kuzvikamu zvakakosha zveinjini kusvika kuzvikamu zvekutumira zvakanyatsonaka, kutsauka kwese kudiki kunogona kukonzera ketani, zvichikonzera ruzha rusina kujairika, kushandiswa kwemafuta kwakawanda uye kunyange njodzi dzekuchengetedza mumotokari. Zvishandiso zvekuyera granite, zvine hunhu hwazvo hwakasiyana uye zvakanakira tekinoroji, zvave zvishandiso zvikuru zvekuona kururama kwezvikamu mukugadzirwa kwezvikamu zvemotokari, zvichiisa hwaro hwakasimba hwekuvandudzwa kweindasitiri yemotokari.
Zvakanakira zvechisikigo zvezvishandiso zvekuyera granite: hwaro hwekugadzikana uye kurongeka
Granite idombo rechisikigo rinoumbwa kuburikidza nemaitiro ekugadzira zvinhu kwenguva refu. Makristaro ayo emukati mezvicherwa akakora uye chimiro chayo chakaenzana, izvo zvinoita kuti ishande zvakanaka. Chekutanga, granite ine chiyero chakaderera kwazvo chekuwedzera kwekupisa, kazhinji kubva pa5 kusvika 7×10⁻⁶/℃. Hunhu uhwu hunoita kuti isakanganiswa nekuchinja kwekupisa. Mumaworkshop ekugadzira zvikamu zvemotokari, kupisa kunokonzerwa nekushanda kwemidziyo uye kuchinja kwekupisa kwezvakatipoteredza kwakajairika. Zvishandiso zvekuyera zvakagadzirwa nezvinhu zvakajairika zvinogona kukonzera zvikanganiso zvehukuru nekuda kwekuwedzera kwekupisa uye kudzikira, zvichikanganisa kurongeka kwekuyera. Zvishandiso zvekuyera granite zvinogona kuchengetedza kugadzikana kwehukuru kana tembiricha ikachinja, zvichiita kuti data rekuyera rive rakavimbika uye kupa zviyero chaizvo zvekugadzirisa zvikamu.
Chechipiri, kuomarara kwakanyanya uye kuramba kupfeka kwegranite ndeimwe mukana mukuru wayo. Granite ine kuomarara kweMohs kwe6 kusvika ku7 haiwanzo shandiswa panguva yekuyera kakawanda. Kugadzirwa kwezvikamu zvemotokari kunowanzo sanganisira basa rakawanda rekuyera rinodzokororwa. Zvishandiso zvekuyera granite zvinogona kuchengetedza nzvimbo dzekuyera dzakarurama panguva yekushandiswa kwenguva refu, kuderedza kutsauka kwekuyera kunokonzerwa nekupfeka kwezvishandiso, kuwedzera hupenyu hwebasa uye kudzikisa mari yekutsiva zvishandiso kumabhizinesi panguva imwe chete. Pamusoro pezvo, granite inewo kugona kwakanaka kwekudzora vibration, iyo inogona kunyudza zvinobudirira vibration inokonzereswa nekushanda kwezvishandiso zvemuchina uye kutakurwa kwezvinhu muworkshop, ichipa nharaunda yakagadzikana yekuyera, kudzivirira kukanganiswa kwevibration nemhedzisiro yekuyera, uye kuve nechokwadi chekuti kuongororwa kwemativi kwakarurama.
Mashandisirwo akakosha ezvishandiso zvekuyera granite mukugadzira zvikamu zvemotokari
Mukugadzirwa kweinjini, maturusi ekuyera granite anoita basa rakakosha. Kururama kwezvikamu zvepakati zvakaita se engine block ne cylinder head kunokanganisa zvakananga kushanda zvakanaka kwemoto uye simba rinobuda. Granite platform, ine flatness yakanyanya (kusvika ± 0.005mm/m2), inopa referensi chaiyo yekuona flatness ye cylinder block uye inoita kuti pave nekuvharwa kwenzvimbo yega yega yejoint. Granite gauge blocks, dial indicator stands nezvimwe zvishandiso zvinogona kuyera nemazvo ma parameter akakosha akadai se dhayamita ye piston pin hole nehukuru hwe crankshaft journal, zvichinyatso dzora kukanganisa pa micrometer level kuti ive nechokwadi chekuti assembly yakarurama uye kushanda zvakanaka kweinjini.
Zvishandiso zvekuyera granite zvakakoshawo mukugadzira zvikamu zvesystem yekutumira mota. Kurongeka kweprofile yemazino emagiya ekutumira, kugona kwezvikamu zveshaft nezvimwe zviratidzo zvine chekuita nekunyorova kwekuchinja kwegiya uye kushanda zvakanaka kwetransmission yemotokari. Chishandiso chekuyera granite guide rail type chinogona kutungamira probe yekuyera kuti inyatsoongorora profile yegiya nekutwasuka kwakanyanya uye kugadzikana, uye kunyatsoona kukanganisa kunogona kusvika ±0.002mm. Mabhokisi egranite square anoshandiswa kuona kumira uye kufanana kwezvikamu zveshaft, zvichiona kururama kwehukama hwekubatanidza pakati pechikamu chimwe nechimwe uye kusimbisa kuvimbika kwesystem yekutumira.
Pamusoro pezvo, panguva yekugadzira zvikamu zvechassis yemotokari, zvinodiwa pakunyatsorurama kwezvikamu zvakaita sesisitimu yekumisikidza uye sisitimu yekufambisa zvakafanana. Zvishandiso zvekuyera granite zvinoyera nekudzora zviyero zvakaita sedhayamita yegomba, upamhi hwesloti, uye kureba kwezvikamu, zvichiita kuti chikamu chimwe nechimwe chechassis chigone kuchinjana uye kurongeka, uye zvinopa vimbiso yekugadzikana uye kubata kwekushanda kwemotokari.
Kurudzira kufambira mberi kwekugadzirwa kwemotokari kusvika pakunyatsorongeka
Sezvo indasitiri yemotokari iri kufambira mberi pakutsvaga ruzivo nemagetsi, zvinodiwa kuti zvikamu zvive zvakanyatsonaka zviri kuramba zvichiwedzera kuomarara. Zvishandiso zvekuyera granite, nekushanda kwadzo kwakasimba uye kunyatsojeka, zvave chombo chakakosha kumakambani anogadzira mota kuti avandudze mhando yezvigadzirwa uye kusimudzira makwikwi emusika. Nekushandisa zvishandiso zvekuyera granite, makambani anogona kudzora zvakanyanya saizi yezvikamu, kuderedza mwero wezvimedu, kupfupisa kutenderera kwekugadzirwa uye kuvandudza kushanda zvakanaka kwezvigadzirwa.
Mune ramangwana, nekufambira mberi kuri kuitwa tekinoroji yekugadzira mota, maturusi ekuyera granite achabatanidzwawo zvakanyanya netekinoroji yekuyera yedhijitari uye masisitimu ekuona otomatiki, zvichiwedzera kuwedzera hunyanzvi uye kururama kwekuyera. Kubva kumotokari dzemafuta dzechinyakare kusvika kumotokari itsva dzesimba, maturusi ekuyera granite acharamba achichengetedza kugadzirwa kwezvikamu zvemotokari nemazvo, zvichikurudzira indasitiri yemotokari kuti ienderere mberi nekukura kwemhando yepamusoro.
