Chivundikiro cha giya yanthawi yamagalimoto.
Magiya anthawi amayambitsidwa munjira zolowera ndi kutulutsa mpweya m'mainjini oyatsira mkati, mu mawotchi ndi machitidwe ena am'deralo omwe ali ndi ubale wotsatizana kuti amalize ntchito zamakina.
Mitundu itatu yotumizira magiya anthawi: kuyendetsa unyolo, lamba wa mano, kuyendetsa magiya.
Magiya abwino ndi oyipa a injini yamagalimoto amayendetsedwa ndi lamba wa mano, omwe ali ndi ubwino wa dongosolo losavuta, phokoso lochepa, ntchito yosalala, kufalikira kwakukulu, kugwirizanitsa bwino, ndi zina zotero, koma mphamvu zake ndizochepa, ndipo ndizosavuta zaka, kutambasula kusinthika kapena kupasuka pambuyo pogwiritsira ntchito nthawi yayitali. Lamba wa mano amakhala wotsekedwa pachivundikiro chakunja, zomwe zimakhala zovuta kuyang'ana momwe zimagwirira ntchito. Pali Mitsubishi galimoto, palibe zizindikiro zoyambira, pambuyo mafuta, kufufuza dera, vuto akadalipo, ndiyeno kutsegula chipinda valavu chivundikirocho, anapeza kuti valavu rocker mkono si ntchito, anatsimikiza kuti nthawi lamba dzino wathyoka. Pambuyo pakusintha kwatsopano, injini siyiyambabe. Chifukwa, pamene lamba dzino lathyoka likugwira ntchito, camshaft imasiya kuthamanga, ndipo crankshaft idzapitirizabe kutembenuza Angle inayake kapena chiwerengero cha matembenuzidwe pansi pa kusinthasintha kwa inertia ya flywheel kapena inertia ya chipangizo chotumizira. Panthawiyi, injiniyo singagwire ntchito, ndipo mozama kwambiri, gawo la valve likuwonongeka, ndipo pisitoni idzapinda pamwamba pa ndodo ya valve pamalo otseguka, zomwe zimapangitsa kuti valavu itsekedwe momasuka. Chifukwa chake, injini zina zokhala ndi malamba osweka, ngakhale chizindikiro cha giya chanthawi chiwongoleredwa, ndipo lamba watsopano wanthawi yayitali asinthidwa, injiniyo imakhala yovuta kuyiyambitsa, kapena imalephera kuyiyambitsa, koma ntchito si yachilendo. , ndi chodabwitsa cha "tempering", "kuwombera", mphamvu zosakwanira, ndi phokoso lowonjezereka limachitika. Pankhaniyi, pokha pochotsa mutu wa silinda ndikusintha valavu ndiye kuti luso la injini likhoza kubwezeretsedwanso. Mphindi ndi zochitika za valavu ziyenera kukhala zogwirizana ndi dziko ndi nthawi ya kayendedwe ka pisitoni, ndipo crankshaft ndi camshaft sizili pa oxis, ziyenera kugwirizanitsidwa ndi njira yopatsirana, njira yotumizira imatsirizidwa. ndi magiya awiri ndi unyolo kapena lamba, ndiye magiya awiri amatchedwa giya nthawi, magiya awiri chizindikiro, Pambuyo kulumikiza unyolo kapena lamba malinga ndi chizindikiro, akhoza kuonetsetsa kuti mphindi ndi zochita za. ntchito ya valve ndi yolondola.
Ntchito ya chivundikiro cha zida za nthawi ndikuteteza zida zanthawi yake ku fumbi ndi madzi. Udindo wa zida zowerengera nthawi ndikuyika sikelo ya nthawi kuti amalize ntchito zowongolera zomwe zikuyenera kuchitika mu chipangizo chamakina.
Zida zanthawi ndi zida zomwe zimagwiritsa ntchito masikelo anthawi kuti amalize ntchito zowongolera pazida zamakina. Magiya anthawi amayambitsidwa munjira zolowera ndi kutulutsa mpweya m'mainjini oyatsira mkati, mu mawotchi ndi machitidwe ena am'deralo omwe ali ndi ubale wotsatizana kuti amalize ntchito zamakina.
Udindo wa zida zowerengera nthawi: zimatha kutenga gawo loyika nthawi pakumaliza ntchito zowongolera zomwe zimafunikira pazida zamakina.
Mitundu itatu yotumizira magiya anthawi: kuyendetsa unyolo, lamba wa mano, kuyendetsa magiya. Magiya abwino ndi oyipa a injini yamagalimoto amayendetsedwa ndi lamba wa mano, omwe ali ndi ubwino wa mawonekedwe osavuta, phokoso lochepa, ntchito yosalala, kufalikira kwakukulu, kugwirizanitsa bwino, ndi zina zotero, koma mphamvu zake ndizochepa, zosavuta kukalamba, zolimba. deformation kapena fracture pambuyo pa kugwiritsidwa ntchito kwa nthawi yayitali, ndipo zimakhala zovuta kuyang'anitsitsa momwe ntchito yake ikuyendera.
Mphindi ndi zochitika za valavu ziyenera kukhala zogwirizana ndi dziko ndi mphindi ya kayendedwe ka pisitoni, ndipo crankshaft ndi camshaft sizili pa oxis, ndipo payenera kukhala njira yopatsirana pakati pawo kuti igwirizane, njira yopatsirana ndiyo. kumalizidwa ndi magiya awiri ndi unyolo kapena lamba, ndiye magiya awiriwa amatchedwa magiya anthawi.
Kulephera kwa nthawi ya injini yagalimoto
Injini ikamathamanga, imapanga phokoso lopitirira kapena lomveka kutsogolo kwa injiniyo. M'mikhalidwe yabwino, kuthamanga kwapamwamba, kumamveka kwambiri; Phokoso silisintha pamene kutentha kumasintha; Phokoso la kuswa moto kwa silinda imodzi silifowoka.
Zomwe zingayambitse kumveka kwachilendo kwa zida zowerengera nthawi
(1) Kusiyana kwa kuphatikiza kwa magiya ndikokulirapo kapena kochepa kwambiri
(2) Mtunda wapakati pakati pa dzenje lalikulu la crankshaft ndi bowo lokhala ndi camshaft limasintha pakagwiritsidwa ntchito kapena kukonza, kukhala wamkulu kapena wocheperako; Mizere yapakati ya crankshaft ndi camshaft siyifanana, zomwe zimapangitsa kuti magiya asamayende bwino.
(3) Mawonekedwe a dzino la giya samakonzedwa, mapindikidwe panthawi ya chithandizo cha kutentha kapena pamwamba pa dzino ndizovuta kwambiri;
(4) Mpata woluma siwolimba kapena kudula mizu kumachitika panthawi yozungulira;
(5) dzino pamwamba ndi zipsera, delamination kapena kuthyoka dzino;
(6) Giya ndi lotayirira kapena kunja pa crankshaft kapena camshaft;
(7) giya ya nkhope yozungulira yozungulira yozungulira kapena yozungulira yozungulira ndi yayikulu kwambiri;
(8) crankshaft kapena camshaft axial chilolezo ndi chachikulu kwambiri;
(9) Magiya sasinthidwa awiriawiri.
(10) Mukasintha crankshaft ndi camshaft yonyamula chitsamba, malo a meshing amasinthidwa.
(11) camshaft timing gear kukonza nati kumasuka.
(12) camshaft yowerengera nthawi ya dzino kutayika, kapena kuphulika kwa giya.
Mawonekedwe anthawi yosinthira mawu amamveka bwino
1) Phokosoli ndi lovuta kwambiri, nthawi zina limakhala lomveka, nthawi zina lopanda phokoso, nthawi zina limadutsa, nthawi zina limapitirira.
2) Injini ikakhala idling kapena liwiro likusintha, pamakhala phokoso losokoneza komanso pang'ono pachivundikiro cha chipinda cha zida panthawi yake, ndipo phokosolo limatha pambuyo poti liwiro liwonjezeke, ndipo phokoso limawonekera injini ikatsika mwachangu. .
3) Phokoso lina silimakhudzidwa ndi kutentha ndi kuyesa kwa silinda imodzi ya moto, ndipo ena amakhudzidwa ndi kutentha, palibe phokoso pamene kutentha kuli kochepa, ndipo pamene kutentha kumatuluka bwino, phokoso likuwonekera.
4) Phokoso lina limatsagana ndi kugwedezeka kwa chivundikiro cha chipinda cha zida zanthawi, ndipo mawu ena samatsagana ndi kugwedezeka.
Chonde tiyimbireni ngati mukufuna such mankhwala.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zolandiridwa kuti mugule.
