Paunenge uchigadzirisa boka repiston rejini, matambudziko anomuka nekuiswa kwepistoni - zvindori zvinobuda kubva mumakororo hazvibvumi kuti piston ipinde zvakasununguka muvharo.Kugadzirisa dambudziko iri, piston mhete mandrels anoshandiswa - dzidza nezvezvishandiso izvi, marudzi avo, dhizaini uye mashandisiro kubva kuchinyorwa.
Chinangwa chepiston ring mandrel
Iyo mandrel yepiston mhete (crimping) mudziyo uri muchimiro chetepi ine clamp yakagadzirirwa kunyudza mhete dzepiston mumikoto yepiston kana yaiswa muinjini block.
Kugadziriswa kweboka repiston reinjini hakuwanzo kupedzwa pasina kubvisa mapistoni kubva mubhuroko rayo.Iko kunotevera kuiswa kwepiston mumasilinda echivharo kunowanzokonzera matambudziko: zvindori zvakaiswa mumagrooves zvinobuda kunze kwepiston uye zvinodzivirira kuti isapinda mune yayo sleeve.Kugadzirisa dambudziko iri, pakugadzirisa injini, zvigadzirwa zvakakosha zvinoshandiswa - mandrels kana crimps episton mhete.
Iyo mandrel yezvindori zvepiston ine basa guru rimwe chete: rinoshandiswa kucheka zvindori uye kunyura mumigero yepiston kuitira kuti iyo yose system ipinde zvakasununguka muhumburumbira we block.Zvakare, iyo mandrel inoshanda segwara pakuisa piston, ichidzivirira kubva kune skewing, pamwe nekudzivirira kukuvadza kune zvindori uye girazi rehumburumbira.
Iyo mandrel yezvindori zvepiston chinhu chiri nyore asi chakakosha zvikuru, pasina izvo hazvibviri kugadzirisa boka repiston uye mamwe maitiro ejini.Asi usati waenda kuchitoro kune mandrel, unofanirwa kunzwisisa mhando dziripo dzemidziyo iyi, magadzirirwo avo uye maitiro.
Mhando, dhizaini uye musimboti wekushanda kwepiston ring mandrel
Nhasi crimps inogona kukamurwa kuita mapoka maviri makuru maererano nemusimboti wekushanda:
● Ratchet (ine ratchet michina);
● Lever.
Vane misiyano yakakura yekugadzira uye imwe nheyo yekushanda.
Ratchet mandrels episton mhete
Midziyo iyi ndeyemhando mbiri huru:
- Neratchet mechanism inofambiswa nekiyi (collar);
- Iine ratchet mechanism yakabatanidzwa mubato rinofambiswa nelever.
Inonyanya kushandiswa ndeye crimps yemhando yekutanga.Izvo zvinosanganisira zvikamu zviviri zvikuru: bhandi resimbi rinoputika uye ratchet mechanism (ratchet).Nheyo yemudziyo ndeye tepi ine hupamhi hwemakumi emakumi emamirimita kusvika 100 mm kana kupfuura.Iyo tepi yakagadzirwa nesimbi, inogona kupisa kupisa kuti iwedzere simba, inoputirwa mumhete.Pamusoro pe tepi pane ratchet mechanism ine maviri akamanikana ribhoni.Paaxis yemuchina pane zvigubhu zvematepi anomonereka uye giya regiya rine chitubu-chakaremerwa pawl.Iyo pawl inogadzirwa nenzira yediki diki, kana yakamanikidzwa, iyo ratchet mechanism inoburitswa uye tepi inosunungurwa.Mune imwe yemadhiramu e tepi, gomba re-axial ye square cross-section inogadzirwa, iyo ine L-shaped wrench (collar) inosungirirwa kusimbisa tepi.
Kune akasiyana-siyana e-ratchet bhandi mandrels ekushanda nemapistoni akareba - iwo akashongedzerwa neaviri ratchet michina (asi, sekutonga, chete negiya rimwe vhiri uye pawl) inotyairwa neimwe wrench.Kureba kwechigadzirwa chakadaro kunogona kusvika 150 mm kana kupfuura.
Chero zvazvingava, mandrels emhando iyi, nekuda kwekugadzirwa kwavo, anowanikwa pasi rose, mazhinji acho anokubvumira kushanda nemapistoni ane dhayamita ye50 kusvika 175 mm, uye mandrels ekuwedzera dhayamita anoshandiswawo.
Iyo ratchet mandrel yezvindori zvepiston inoshanda zviri nyore: kana iyo ratchet axis ichitenderedzwa nekorari, giya regiya rinotenderedzwa, iro pawl rinosvetuka zvakasununguka.Paunenge uchimira, pawl collar inomira pazino revhiri uye inodzivirira kuti irege kudzokera shure - izvi zvinovimbisa kugadziriswa kwe mandrel uye, maererano, crimping yezvindori mumakororo ayo.
Crimping nemubato umo ratchet mechanism yakavakirwa mukati ine mudziyo wakafanana, asi ivo havana collar - basa rayo rinoitwa neakavakirwa-mukati lever.Kazhinji, zvigadzirwa zvakadaro zvine bhanhire rakamanikana, rakagadzirirwa kushanda nemudhudhudhu uye mamwe mashoma-vhoriyamu masimba masimba.

Lever mandrels episton mhete
● Matepi ane crimping ane pliers kana mamwe maturusi;
● Matepi ane crimping ane chakakosha chishandiso - zvikwekwe, kusanganisira ratchet;
● Matepi ane crimping ne-built-in lever ane nzira yekuvhara uye kukwanisa kugadzirisa kuhupamhi hwepiston.
Iyo yakanyanya kupfava yerudzi rwekutanga ndeiyi: kazhinji idzo dzindori dzakavhurika dzakagadzirwa nesimbi yakakora ine mativi maviri kana zvishwe kumagumo ese, ayo anounzwa pamwe ne pliers kana pliers.Mandrel akadaro haana kudzorwa, anogona chete kushandiswa nemapistoni edhayamita imwe chete, uye nekuwedzera, haana kunyatso nyore kushandisa, nekuti anoda kugara achichengeterwa pliers kana pliers kusvikira piston yanyatsoiswa mune sleeve.
Iyo mandrels emhando yechipiri yakanyanya kukwana, inogadzirwawo nenzira yezvindori zvakazaruka, zvisinei, mapeji anokosha anoshandiswa kune screed yavo pamwe nekukwanisa kugadzirisa mune imwe nzvimbo.Makirimpi akadaro haadi kugara uchishandiswa kwekuedza kune mite, saka iwo ari nyore uye ari nyore kushandisa.Kazhinji, zvishandiso zverudzi urwu zvinopihwa nenzira yemakiti ane akati wandei mandrels emhando dzakasiyana.

Kururamisa kusarudzwa uye kushandiswa kwepiston ring mandrel
Sarudzo yepiston ring mandrel inofanirwa kuitwa zvichienderana nehunhu hwepiston uye basa rinofanirwa kuitwa.Kana motokari imwe chete iri kugadzirwa, saka zvine musoro kusarudza crimping iri nyore ine ratchet mechanism kana kunyange neplier clamp.Kana kuiswa kwepistoni kuchiitwa nguva dzose (somuenzaniso, muchitoro chekugadzirisa motokari), zvino zviri nani kupa zvido kune imwechete yebhanhire remabhandi mandrels ane ratchet mechanism kana seti ye mandrels emhando dzakasiyana-siyana.Izvo zvinofanirwa kunzwisiswa kuti kune yakakura mota pistons zviri nani kushandisa yakafara mandrels, uye yemudhudhudhu pistons - yakamanikana.
Kutenga kushandiswa kwehunyanzvi, seti yakazara yezvishandiso zvekugadzirisa mapoka episton inogona kuve inonakidza sarudzo.Makiti akadaro anogona kunge aine akasiyana mandrels episton mhete (ese ari maviri tepi uye ratchet mite), rin'i dzinodhonza uye zvimwe zvishandiso.
Kushanda nemandrel episton mhete kunowanzo nyore, kunouya pasi kune akati wandei maoparesheni:
● Kuti zvive nyore, shandisa piston mune vice, gadzira grooves yayo nemhete uye siketi zvakanaka nemafuta;
● Isa zvindori mumigero maererano nemazano - kuitira kuti zvikamu zvavo zvekuvhara zvive kure ne120 degrees kubva kune mumwe;
● Zora mukati memandrel nemafuta;
● Isa mandrel papiston;
● Kushandisa wrench, lever kana pliers (zvichienderana nemhando yechigadzirwa), simbisa mandrel papiston;
● Isai piston pamwe chete nemandrel muvhavha yevhavha, shandisa nyundo kana nyundo kuburikidza ne gasket kuti unyatsogogodza piston kubva kune mandrel mu cylinder;
● Mushure mokunge piston yakanyatsobatanidzwa mu cylinder, bvisa uye usunungure mandrel.
Seti yepiston mhete mandress
Paunenge uchishanda ne mandrel, zvakakosha kunyatsosimbisa: kana crimping yakanyanya kusimba, zvindori hazvizopindi zvakakwana mu grooves uye zvichakanganisa kuiswa kwepiston mumutsetse;Nekunyanya crimping, piston ichave yakaoma kugogodza kunze kweiyo mandrel, uye mune iyi kesi, mashini echigadzirwa anogona kutyora.
Nekusarudzwa kwakaringana uye kushandiswa kwepiston ring mandrel, kuungana kweinjini mushure mekugadziriswa kweboka repiston kunoda nguva shoma uye kushanda nesimba.
