Kupanga zinthu, kuthetsa mavuto ndi kusintha VAZ 2107 camshaft

03.03.2023 /

Kuchita bwino kwa injini yonse yamagalimoto mwachindunji kumadalira momwe camshaft ilili. Ngakhale kulephera pang'ono kwa msonkhano wogawira gasiwu kumakhudza mphamvu ndi mawonekedwe a mphamvu yamagetsi, osatchulanso kuchuluka kwamafuta ndi kuwonongeka kofananira. M'nkhaniyi tikambirana za cholinga cha camshaft, mfundo ya ntchito yake, malfunctions waukulu ndi mmene kuchotsa iwo pogwiritsa ntchito chitsanzo cha galimoto Vaz 2107.

Camshaft VAZ 2107

The camshaft ndiye chinthu chachikulu cha makina ogawa gasi a injini yamagalimoto. Ichi ndi gawo lazitsulo zonse, lopangidwa ngati silinda yokhala ndi magazini okhala ndi makamera oyikidwapo.

Cholinga

Shaft nthawi imagwiritsidwa ntchito kuwongolera njira zotsegulira ndi kutseka ma valve mu zipinda zoyaka moto za injini. Mwa kuyankhula kwina, imagwirizanitsa kayendetsedwe ka kayendetsedwe ka mphamvu, m'kupita kwa nthawi kulola kusakaniza kwa mpweya wa mafuta mu zipinda zoyatsira ndi kutulutsa mpweya wotulutsa mpweya kuchokera kwa iwo. Camshaft ya "zisanu ndi ziwiri" imayendetsedwa ndi kuzungulira kwa nyenyezi yake (giya), yolumikizidwa ndi unyolo ku giya la crankshaft.

Ali kuti

Kutengera kapangidwe ka injini, shaft nthawi imatha kukhala ndi malo osiyanasiyana: kumtunda ndi kumunsi. Pamalo ake otsika, imayikidwa mwachindunji mu block ya silinda, ndipo pamwamba - pamutu wa block. Pa "zisanu ndi ziwiri" camshaft ili pamwamba pa mutu wa silinda. Kukonzekera kumeneku, poyamba, kumapangitsa kuti zikhale zosavuta kukonzanso kapena kusinthidwa, komanso kusintha ma valve. Kuti mufike kumalo osungira nthawi, ndikwanira kuchotsa chivundikiro cha valve.

Mfundo yogwirira ntchito

Monga tanenera kale, camshaft imayendetsedwa ndi crankshaft gear. Panthawi imodzimodziyo, kuthamanga kwa kuzungulira kwake, chifukwa cha kukula kosiyana kwa magiya oyendetsa galimoto, kumachepetsedwa ndendende ndi theka. Kuzungulira kwa injini yathunthu kumachitika m'magulu awiri a crankshaft, koma shaft yanthawi imapangitsa kusintha kumodzi kokha, komwe imatha kulola kusakaniza kwa mpweya wamafuta mu masilindala ndikutulutsa mpweya wotuluka.

Kutsegula (kutseka) kwa ma valve ogwirizana kumatsimikiziridwa ndi zochita za makamera pazitsulo zonyamula valve. Zikuwoneka ngati izi. Pamene shaft ikuzungulira, mbali yotuluka ya cam imakankhira pusher, yomwe imasamutsira mphamvu ku valve yodzaza masika. Chomalizacho chimatsegula zenera kuti mulowetse chisakanizo choyaka moto (kutulutsa mpweya). Kamera ikatembenuka, valavu imatseka pansi pakuchita kwa masika.

Makhalidwe a camshaft VAZ 2107

Kugwira ntchito kwa nthawi shaft VAZ 2107 kumatsimikiziridwa ndi magawo atatu akuluakulu:

  • m'lifupi mwa magawo ndi 232о;
  • kuchuluka kwa valve - 40о;
  • valavu yotulutsa mpweya - 42о.

Chiwerengero cha makamera pa camshaft chimafanana ndi chiwerengero cha ma valve olowetsa ndi kutuluka. "Zisanu ndi ziwiri" zili ndi zisanu ndi zitatu - ziwiri pazitsulo zinayi zilizonse.

Kodi n'zotheka kuwonjezera mphamvu ya injini ya VAZ 2107 ndi kukhazikitsa camshaft wina

Mwinamwake, mwiniwake aliyense wa "zisanu ndi ziwiri" amafuna kuti injini ya galimoto yake igwire ntchito osati popanda kusokoneza, komanso ndi mphamvu zambiri. Chifukwa chake, amisiri ena akuyesera kuyimba zida zamagetsi m'njira zosiyanasiyana. Imodzi mwa njirazi ndi kukhazikitsa wina, "pamwamba" camshaft.

Chinsinsi cha kukonza

Mwachidziwitso, ndizotheka kuonjezera zizindikiro za mphamvu za mphamvu yamagetsi mwa kuwonjezera m'lifupi mwa magawo ndi kutalika kwa valavu yolowera. Chizindikiro choyamba chimatsimikizira nthawi yomwe valavu yolowetsa idzakhala yotseguka, ndipo imawonetsedwa pamphepete mwa kuzungulira kwa nthawi. Kwa "asanu ndi awiri" ndi 232о. Kutalika kwa valavu yolowera kumatsimikizira malo a dzenje momwe mpweya wosakanikirana wamafuta udzaperekedwa kuchipinda choyaka. Kwa VAZ 2107 ndi 9,5 mm. Choncho, kachiwiri, mwachidziwitso, ndi kuwonjezeka kwa zizindikiro izi, timapeza voliyumu yowonjezereka ya kusakaniza koyaka muzitsulo, zomwe zingathe kukhudza mphamvu ya mphamvu yamagetsi.

N'zotheka kuonjezera m'lifupi mwa magawo ndi kutalika kwa kukweza kwa valve yolowera mwa kusintha makonzedwe a makamera ogwirizana a shaft nthawi. Popeza ntchito zotere sizingachitike mu garaja, ndikwabwino kugwiritsa ntchito gawo lomalizidwa kuchokera kugalimoto ina pakukonzekera kotere.

Camshaft kuchokera ku "Niva"

Pali galimoto imodzi yokha, camshaft yomwe ili yoyenera "zisanu ndi ziwiri". Ichi ndi VAZ 21213 Niva. Kutalika kwake kuli ndi gawo la 283о, ndipo valavu yolowetsamo ndi 10,7 mm. Kodi unsembe wa gawo ili pa injini Vaz 2107 kupereka chinachake kwenikweni? Zochita zikuwonetsa kuti inde, kusintha pang'ono pakugwira ntchito kwa gawo lamagetsi kumawonedwa. Kuwonjezeka kwa mphamvu ndi pafupifupi 2 malita. ndi., koma pa liwiro lotsika. Inde, "zisanu ndi ziwiri" zimayankha mokulirapo pang'ono pokankhira chowongolera poyambira, koma pambuyo poti chiwonjezeke, mphamvu yake imakhala yofanana.

Masewera a camshafts

Kuphatikiza pa shaft ya nthawi ya Niva, pa VAZ 2107 mutha kukhazikitsanso imodzi mwamitsinje yomwe imapangidwira "masewera" kukonza magawo amagetsi. Zigawo zotere zimapangidwa ndi mabizinesi angapo apakhomo. Mtengo wawo umachokera ku ruble 4000-10000. Taganizirani makhalidwe a camshafts amenewa.

Zowonongeka za camshaft VAZ 2107, zizindikiro zawo ndi zifukwa

Popeza kuti shaft yanthawiyo imakhala yokhazikika komanso yotentha nthawi zonse, sichingakhalepo mpaka kalekale. Zimakhala zovuta ngakhale kwa katswiri kudziwa kuti mfundo imeneyi yalephera popanda kufufuza mwatsatanetsatane ndi kuthetsa mavuto. Pakhoza kukhala zizindikiro ziwiri zokha za kusagwira ntchito kwake: kuchepa kwa mphamvu ndi kugogoda kofewa, komwe kumawonekera makamaka pansi pa katundu.

Zowonongeka zazikulu za camshaft ndi izi:

  • kuvala matupi ogwira ntchito a makamera;
  • kuvala kwa malo okhala ndi magazini;
  • deformation ya gawo lonse;
  • kuphulika kwa shaft.

Kuvala makamera ndi makosi

Kuvala ndizochitika mwachilengedwe mu gawo lozungulira nthawi zonse, koma nthawi zina kumatha kukhala mopambanitsa komanso msanga. Izi zimabweretsa:

  • Kuthamanga kwamafuta osakwanira m'dongosolo, chifukwa chake mafutawo samalowa m'malo odzaza kapena amabwera pang'ono;
  • mafuta a injini otsika kapena osagwirizana;
  • ukwati pakupanga shaft kapena "bedi" lake.

Pakakhala kuvala pamakamera, mphamvu ya injini imachepetsedwa kwambiri, chifukwa, atatopa, sangathe kupereka m'lifupi mwagawo loyenera kapena kukweza ma valve ofunikira.

Kusintha

Mapindikidwe a camshaft amawoneka chifukwa cha kutenthedwa kwakukulu komwe kumachitika chifukwa cha kusagwira bwino ntchito kwamafuta kapena kuziziritsa. Pachiyambi choyamba, vuto ili likhoza kuwonekera mwa mawonekedwe a kugogoda kwa khalidwe. Ngati akukayikira kusweka koteroko, ntchito zina za galimoto si ovomerezeka, chifukwa akhoza kuletsa lonse gasi limagwirira injini.

Kukhumudwa

Kuphulika kwa camshaft kungakhale chifukwa cha kusinthika kwake, komanso ntchito yosagwirizana ndi nthawi. Izi zikavuta, injini imayima. Mofanana ndi vutoli, ena amawuka: kuwonongeka kwa "bedi" la shaft, kusokonezeka kwa ma valve, malangizo, kuwonongeka kwa mbali za gulu la pistoni.

Kuthetsa nthawi kutsinde VAZ 2107

Pamene camshaft imachotsedwa pa "bedi", ndikofunikira kuyesa momwe zilili. Izi zimachitika poyamba. Camshaft iyenera kusinthidwa ngati malo ake ogwirira ntchito (makamera ndi zofalitsa) ali ndi:

  • zikande;
  • zoipa;
  • kudula kuvala (kwa makamera);
  • kuphimba zitsulo zotayidwa kuchokera pa "bedi" (zothandizira makosi).

Kuonjezera apo, camshaft iyenera kusinthidwa ngati kawonekedwe kakang'ono kamene kamapezeka.

Mlingo wa kuvala kwa makosi onyamula ndi mayendedwe okha amatsimikiziridwa pogwiritsa ntchito micrometer ndi caliper. Gome ili m'munsiyi likuwonetsa ma diameter ovomerezeka a makosi ndi malo ogwirira ntchito a zothandizira.
