Iyo cheni yekufambisa ndeye meshing kutapurirana, uye avhareji yekutapurirana reshiyo ndeyechokwadi.Iyo mechanical transmission inotumira simba uye kufamba nekushandisa meshing yeketani uye mazino e sprocket.
cheni
Kureba kweketani kunoratidzwa muhuwandu hwezvibatanidzi.Huwandu hwemaketani zvinongedzo zvinonyanya kuve nhamba yakaenzana, kuitira kuti kana ketani yabatanidzwa mumhete, yekunze cheni ndiro uye yemukati cheni ndiro inongobatanidzwa, uye majoini anogona kuvharwa nechirimo clips kana cotter pini.Kana iyo nhamba yezvibatanidza isinganzwisisike, shanduko yekubatanidza inodiwa.Kana cheni iri pasi pekunetsekana, chinongedzo chekushandura chinotakurawo mitoro yekukombama uye kazhinji inofanirwa kudzivirirwa.Cheni ine mazino inoumbwa nemapunched toothed cheni ma plates akabatanidzwa nemahinji.Kuti udzivise kuti cheni ichidonha kana meshing, cheni yacho inofanirwa kunge iine girodhi ndiro (yakakamurwa kuita yemukati gwara mhando uye yekunze gwara remhando).Mativi maviri eplate yeketani ine mazino ari mativi akatwasuka, uye rutivi rwecheni ndiro meshes nemazino profiles e sprocket panguva yekushanda.Hinge inogona kugadzirwa pair sliding kana rolling pair, uye roller type inogona kuderedza. kukakavara uye kupfeka, uye mhedzisiro yacho iri nani pane iyo yekubereka pad mhando.Zvichienzaniswa nemaroller cheni, maketani ane mazino anomhanya zvakanaka, ane ruzha rwakaderera, uye ane hunyanzvi hwekutsungirira mitoro yemhedzisiro;asi zvimiro zvavo zvakaoma, zvinodhura, uye zvinorema, saka mafomu avo haana kuwanda sengetani dzemaroller.Maketani ane mazino anonyanya kushandiswa pakumhanya-mhanya (cheni inomhanya kusvika 40m/s) kana yakakwirira-chaiyo kufambisa kutapurirana.Chiyero chenyika chinongotaura huwandu hwepamusoro uye hudiki hweiyo mazino arc radius, zino groove arc radius uye zino groove angle yezino groove ye roller chain sprocket (ona GB1244-85 kuti uwane ruzivo).Iyo chaiyo yechiso chimiro cheimwe neimwe sprocket inofanirwa kunge iri pakati peiyo yakakura uye diki maumbirwo ekukochekera.Kurapa uku kunobvumira kuchinjika kukuru mukugadzirwa kweiyo sprocket zino profile curve.Nekudaro, iyo zino chimiro chinofanirwa kuve nechokwadi chekuti cheni inogona kupinda uye kubuda meshing mushe uye yakasununguka, uye inofanirwa kuve nyore kugadzirisa.Kune akawanda marudzi ekupedzisira zino profile curves inosangana nezvinodiwa pamusoro apa.Iyo inonyanya kushandiswa mazino chimiro ndeye "matatu arcs uye imwe yakatwasuka mutsara", ndiko kuti, iyo yekupedzisira inotarisana nezino chimiro inoumbwa nearcs matatu uye mutsara wakatwasuka.
sprocket
Iwo maviri mativi emazino chimiro che sprocket shaft surface ane arc-shaped kufambisa kupinda nekubuda kwecheni links.Kana iyo zino chimiro ichigadziriswa neyakajairwa maturusi, hazvifanirwe kudhirowa iyo yekupedzisira yakatarisana nezino chimiro pane sprocket inoshanda dhizaini, asi iyo sprocket shaft pamusoro zino chimiro chinofanira kudhonzwa kufambisa kutendeuka kwe sprocket.Ndokumbira utarise kune yakakodzera dhizaini yemanyorero eiyo chaiyo zviyero zveshaft pamusoro pezino profile.Mazino e sprocket anofanirwa kuve nesimba rakakwana rekubatana uye kupfeka kuramba, saka nzvimbo dzezino dzinowanzo batwa nekupisa.Iyo sprocket diki ine yakawanda meshing nguva pane yakakura sprocket, uye simba rekuita rakakura zvakare, saka zvinhu zvinoshandiswa zvinofanirwa kunge zviri nani pane izvo zvesprocket hombe.Inowanzo shandiswa sprocket zvinhu ndeye carbon steel (yakadai seQ235, Q275, 45, ZG310-570, nezvimwewo), grey cast iron (yakadai seHT200), nezvimwewo zvakakosha sprockets zvinogona kugadzirwa nesimbi yealloy.Iyo sprocket ine dhayamita diki inogona kugadzirwa kuva yakasimba mhando;iyo sprocket ine dhayamita yepakati inogona kugadzirwa kuva orifice mhando;iyo sprocket ine dhayamita yakakura inogona kugadzirwa seyakasanganiswa mhando.Kana mazino akakundikana nekuda kwekupfeka, giya remhete rinogona kutsiviwa.Saizi ye sprocket hub inogona kureva pulley.
