Padanho guru reindasitiri yemazuva ano, pane chinhu chinoita sechiri nyore asi chakakosha chinotsigira chinyararire mashandiro emichina isingaverengeki, kureva cheni inotenderera. Chinyorwa chino chichakupinza mukati menyika yecheni dzinotenderera, kubva pakushanda kwayo kusvika pabasa rayo rinokosha muindasitiri yemazuva ano. Ngationgororei chakavanzika chemoyo weindasitiri iyi pamwe chete.
Mavambo nekushanduka-shanduka kwecheni dzinotenderera
Kwakatangira cheni dzinotenderera dzinogona kuteverwa kusvika muna 180 BC, apo China yakagadzira mudziyo unonzi "chain drive" wekusimudza mavhiri emvura. Zvisinei, cheni chaiyo inotenderera yakagadzirwa naCharles F. Kratzer mukupera kwezana remakore rechi19. Akavandudza cheni yechinyakare yakatsetseka uye akawedzera maroller, izvo zvakavandudza zvikuru kushanda zvakanaka uye kugona kwemutoro wecheni.
Nekufambira mberi kwekushanduka kwemaindasitiri, kushandiswa kwemaroller chain kwakaramba kuchikura. Kubva kumabhasikoro kusvika kumotokari, kubva kumichina yemachira kusvika kumichina yemazuva ano yekugadzira maindasitiri, maroller chain ari kwese kwese. Dhizaini yayo inogara ichigadziriswa kuti ienderane nekumhanya kwakanyanya uye mitoro yakakura.
Chimiro uye musimboti wekushanda kwecheni inotenderera
Cheni yeroller ine zvisungo zvakabatana, chimwe nechimwe chine maplate maviri echeni neroller imwe. Maplate echeni anowanzogadzirwa nesimbi, nepo maroller akagadzirwa nesimbi yakaoma kuderedza kukweshana uye kuvandudza kusakara. Zvisungo zvecheni zvakabatanidzwa nemapini nemachira kuti zvigadzire chinhu chakasimba uye chinochinjika.
Nheyo yekushanda kwecheni inotenderera inobva pakukweshana uye kukweshana. Kana simba (senge mota) richifambisa sprocket, mazino e sprocket mesh nemaplate emukati echeni inotenderera, zvichisunda cheni dzinoenderana nenzira yakatarwa. Ma rollers anotenderera pakati pecheni dzinobatanidza nema sprockets, zvichideredza kukweshana uye zvichiita kuti kutapurirana kwesimba kuve nyore.
Zvakanakira uye mashandisirwo emaketani anotenderera
Chikonzero nei maroller chain achishandiswa zvakanyanya muindasitiri imhaka yezvibatsiro zvinotevera:
Kushanda zvakanaka: Kukweshana kwemaketani anotenderera kwakaderera zvikuru pane kukweshana kunotsvedza, zvinoreva kuti kunogona kuendesa simba guru nekushandisa simba shoma.
Kutakura kwakanyanya: Nekuda kwekuvapo kwemaroller, maroller cheni anogona kutsungirira mitoro mikuru uye akakodzera michina inorema.
Kugara kwenguva refu: Macheni emhando yepamusoro anogona kushandiswa kwemakore mazhinji nekugadzirisa kwakakodzera, zvichideredza mari yekutsiva.
Kuvimbika: Dhizaini yemaroller chains iri nyore uye yakavimbika, uye inogona kushanda zvakanaka kunyangwe munzvimbo dzakaoma dzekushanda.
Mashandisirwo emaketani anotenderera akafara zvikuru, kusanganisira asi kwete kungogumira pane:
Indasitiri yemotokari: Muinjini yemotokari, cheni dzinotenderera dzinoshandiswa kufambisa camshaft kuti ive nechokwadi chekuti mavharuvhu anovhurwa nekuvharwa nemazvo.
Mabhasikoro nemidhudhudhu: Macheni anotenderera ndiwo musimboti wesystem yekufambisa mabhasikoro nemidhudhudhu, achitumira simba remapedali kumavhiri.
Michina yemumaindasitiri: Mumaindasitiri akadai semachira, kurongedza, uye kudhinda, maroller cheni anoshandiswa kufambisa zvikamu zvakasiyana-siyana zvemakanika kuti zviite kufamba kwakanyatsoenderana.
Michina yekurima: Mumichina yekurima yakaita semichina yekukohwa nematrakita, maroller chains anoshandiswa kufambisa simba uye kuvandudza mashandiro ebasa.
Kugadzirisa nekugadzirisa matambudziko emaketani anotenderera
Kunyangwe cheni dzinotenderera dzichizivikanwa nekugara kwenguva refu, kuchengetedza kwakakodzera kuchiri kukosha. Heano mamwe matanho ekutanga ekugadzirisa:
Kuongorora nguva dzose: Tarisa kana cheni dzinobatanidza cheni dzichiratidza zviratidzo zvekusakara, kutatamuka, kana kukuvara.
Kuchenesa: Chenesa cheni yeroller nguva nenguva kubvisa guruva nemafuta kuderedza kupera.
Kuzora: Rora mafuta echeni akakodzera kuderedza kukweshana uye kudzivirira ngura.
Kugadzirisa kushushikana: Chengetedza kushushikana kwakakodzera. Kusununguka zvakanyanya kana kusimba zvakanyanya kunokanganisa hupenyu uye kushanda zvakanaka kwecheni.
Kana cheni yeroller ikakundikana, matambudziko anowanzoitika anosanganisira:
Kupera kwecheni: Kupera kwecheni zvakanyanya kunogona kukonzera kuti cheni ityoke.
Kutambanudza cheni: Kushandiswa kwenguva refu kuchatambanudza cheni zvishoma nezvishoma uye kuchakanganisa kusungirirwa kwayo.
Kukuvadzwa kweroller: Kukuvadzwa kweroller kuchaita kuti simba rekufambisa rirege kugadzikana.
Pamatambudziko aya, kutsiva nekugadzirisa zvinhu nenguva kunodiwa.
Mafambiro emangwana ekuvandudza macheni anotenderera
Nekufambira mberi kwetekinoroji, maroller chains ari kuramba achikura. Heano mamwe maitiro anogona kuitika mune ramangwana:
Kugadzira zvinhu zvitsva: Kushandiswa kwezvinhu zvitsva, zvakaita sepurasitiki yakasimba uye zvinhu zvakasanganiswa, kunogona kuita kuti cheni dzinotenderera dzive dzakareruka uye dzakasimba.
Ungwaru: Maketeni anotenderera ane masensa akabatanidzwa anogona kutarisa mamiriro awo panguva chaiyo uye kufanotaura zvinodiwa pakugadzirisa.
Dhizaini isingakuvadzi nharaunda: Zvinhu zvinogona kushandiswazve uye dhizaini isingashandise simba rakawanda zvichaita kuti cheni dzemaroller dzive dzisingakuvadzi nharaunda.
Kugadzirisa: Nekuvandudzwa kwetekinoroji yekudhinda ye3D, maroller chain akagadzirwa achave anokwanisika kusangana nezvinodiwa zvemashandisirwo chaiwo.
Mhedziso
Roller chain, moyo weindasitiri uye kurova kwemoyo kwemichina, inotsigira mashandiro eindasitiri yemazuva ano nekugadzirwa kwayo kuri nyore uye kune simba. Nekufambira mberi kuri kuitwa tekinoroji, roller chain icharamba ichiita basa risingatsiviwi mumunda wemaindasitiri. Kunzwisisa roller chain kunzwisisa musimboti weindasitiri uye kunzwisisa kukosha kwemichina.
