Momwe mungakulitsire lamba wa alternator? - kanema wotambasula pamagalimoto osiyanasiyana

Lamba wa alternator umagwira ntchito yofunika kwambiri - imasamutsa kuzungulira kwa crankshaft kupita ku pulley ya alternator, yomwe imayitanitsa batire poyendetsa, ndipo kuchokera pamenepo magetsi akuyenda kwa onse ogula magetsi m'galimoto yanu.

Madalaivala onse akulangizidwa kuti ayang'ane kuthamanga kwa lamba wa alternator nthawi ndi nthawi. Lamba womangika bwino sayenera kupitirira centimita imodzi ngati mulimbikira ndi mphamvu ya ma kilogalamu atatu kapena anayi. Muthanso kugwiritsa ntchito dynamometer kuti muwone (chinyumba chachitsulo chamba ndichoyenera) - ngati mbedza yake imakokedwa pa lamba ndikukokera kumbali, imasuntha mamilimita 10-15 ndi mphamvu ya 10 kg / cm.

Ngati palibe wolamulira kapena dynamometer pafupi, ndiye kuti mutha kuyang'ana ndi diso - ngati muyesa kupotoza lamba, liyenera kutembenuka mpaka madigiri 90, osatinso.

M'kupita kwa nthawi, kuchuluka kwa lamba kumachepa ndipo kumatambasuka, phokoso lodziwika bwino limamveka - lamba limagwera pa pulley ndikuyamba kutentha. Izi zadzaza ndi mfundo yakuti pakapita nthawi imatha kusweka. Kuphatikiza apo, pulley ya crankshaft imapanga kusintha kosagwira ntchito, ndiko kuti, imagwira ntchito mopanda mphamvu ndipo jenereta sipanganso mphamvu zonse - makina onse amagetsi agalimoto amavutika.

Kulimbitsa lamba wa alternator si ntchito yovuta kwambiri, makamaka pa VAZs zoweta ndi Ladas. Mu zitsanzo zamakono kwambiri, mu Priore yemweyo, mwachitsanzo, pali chodzigudubuza chotsitsimula chokhala ndi malo ochepetsera omwe amawongolera kuchuluka kwa zovuta za lamba.

Ntchito yomangirira lamba ikhoza kukhala yovuta chifukwa cha malo ovuta a jenereta ndi pulley ya crankshaft. Zitsanzo zina ziyenera kuyendetsedwa mu dzenje loyang'ana, pamene zina ndizokwanira kuti mutsegule hood, monga VAZ 2114. Pa zitsanzo zamakono za VAZ, zonsezi zimachitika mosavuta: jenereta imamangiriridwa ku crankcase ndi bawuti lalitali, chifukwa chake mutha kusuntha jenereta mu ndege yowongoka, ndipo pamwamba pake pali bala yokhala ndi kagawo kwa bawuti ina kukonza malo a jenereta mu ndege yopingasa.

Zomwe zimafunika ndikumasula phiri la jenereta, kumasula nati pa bar, kuikonza pamalo oterowo pamene lamba ali wokwanira, sungani nati ndikuyika jenereta.

Palibe vuto kuti lamba likokedwe mwamphamvu kwambiri, chifukwa izi zidzatsogolera ku kukakamiza kwakukulu kudzagwiritsidwa ntchito pakuyenda kwa alternator pulley ndipo idzangowonongeka pakapita nthawi, zomwe zidzasonyezedwa ndi mluzu, kugwedeza. ndi kusakwanira kwa batire.

Pa Lada Kalina, lamba wa alternator amamangika pogwiritsa ntchito ndodo yolumikizira. Ndikokwanira kungomasula nati wa loko, kumasula ndodo yokhayokha pang'ono, ndiyeno kumangitsa mtedzawo m'malo mwake. Momwemonso, mutha kumasula kugwedezeka kwa lamba, ndipo ngati mukufuna kusintha kwathunthu, ndiye kuti ndodo yachitsulo imachotsedwa ndipo lamba watsopano amaikidwa.

Ndikoyenera kudziwa kuti pamene mukugwedeza lamba wa alternator, musaiwale kuyang'ana mkhalidwe wake - sayenera kukhala ndi ming'alu kapena ma abrasions. Ngati alipo, ndiye kuti ndi bwino kugula lamba watsopano, popeza siwokwera mtengo kwambiri.

Ngati tikulankhula za Lada Priora, pamene lamba alternator limafotokoza trajectory yaikulu - komanso atembenuza pulleys wa mpweya woziziritsa ndi chiwongolero mphamvu, ndiye wodzigudubuza ndi udindo mavuto kumeneko.

Ngati palibe chidziwitso pakumangirira malamba oterowo, ndiye kuti ndi bwino kuchita zonsezi pamalo operekera chithandizo, ngakhale njira yokhayo sizovuta - muyenera kumasula nati yolumikizira, kenako tembenuzani khola la eccentric ndi wrench yapadera yolumikizirana. mpaka lamba litakhazikika, limbitsani mtedza womangira kumbuyo. Koma zoona zake n'zakuti n'kovuta kuganiza zolondola mavuto lamba, chifukwa dera kukhudzana ndi pulleys amachepetsa chifukwa trajectory. Mutha kuyesa kuchita mwachisawawa.

Lamba wa alternator amamangika pafupifupi mofananamo pamitundu ina yamakono, komabe, kuti mufike, muyenera kuchotsa mawilo, kumasula makina otetezera matope kapena chitetezo cha pulasitiki, kuchotsa chivundikiro cha nthawi, chomwe, ndithudi, zimatenga nthawi yambiri.
