Kutumirwa kwecheni itransmission ine meshing, uye avhareji yehuwandu hwetransmission yakarurama. Itransmission yemakanika inotumira simba nekufamba nekushandisa meshing yecheni nemazino e sprocket.
cheni
Kureba kwecheni kunoratidzwa nenhamba yezvinobatanidza. Huwandu hwezvinobatanidza cheni zviri nani kuti huve nhamba yakaenzana, kuitira kuti kana cheni yakabatana murin'i, ndiro yekunze yecheni nendiro yemukati yecheni zvakabatana chete, uye majoini anogona kuvharwa nezvidimbu zvechitubu kana mapini ecotter. Kana huwandu hwezvinobatanidza husina kurongeka, zvinobatanidzwa zvekuchinja hunodiwa. Kana cheni iri pasi pekumanikidzwa, chinongedzo chekuchinja chinotakurawo mimwe mitoro yekukotama uye kazhinji chinofanira kudzivirirwa. Cheni ine mazino inoumbwa nemaplate akawanda echeni ane mazino akaboorwa akabatanidzwa nemahinge. Kuti cheni isadonhe painosungirirwa, cheni inofanira kuva neplate yekutungamira (yakakamurwa kuita rudzi rwekutungamira rwemukati nerudzi rwekutungamira rwekunze). Mativi maviri eplate yecheni ine mazino mativi akatwasuka, uye divi replate yecheni rine chimiro chezino che sprocket panguva yekushanda. Hinge inogona kugadzirwa kuita sliding pair kana rolling pair, uye rudzi rweroller runogona kuderedza kukweshana nekusakara, uye mhedzisiro yacho iri nani pane yerudzi rwebearing pad. Zvichienzaniswa neroller chains, cheni dzine mazino dzinomhanya zvakanaka, dzine ruzha rwakaderera, uye dzine kugona kwakanyanya kutsungirira mitoro yekukanganisa; asi maumbirwo adzo akaomarara, anodhura, uye anorema, saka mashandisirwo adzo haana kukura semaketani anotenderera. Maketani ane mazino anonyanya kushandiswa pakumhanya kwakanyanya (kumhanya kwecheni kusvika 40m/s) kana kufambiswa kwemafambiro akanyatsojeka. Mutemo wenyika unongotaura chete kukosha kwepamusoro uye kushoma kweredhiyo yekumusoro kwezino, radius yemugero wezino uye kona yemugero wezino wemugero wecheni inotenderera (ona GB1244-85 kuti uwane rumwe ruzivo). Chimiro chaicho chechiso che sprocket yega yega chinofanira kunge chiri pakati pemaumbirwo makuru nemadiki ekukomba. Kurapa uku kunobvumira kuchinjika kukuru mukugadzirwa kwemugero wecheni inotenderera. Zvisinei, chimiro chezino chinofanira kuve nechokwadi chekuti cheni inogona kupinda nekubuda meshing zvakanaka uye zvakasununguka, uye inofanira kuve nyore kugadzirisa. Kune mhando dzakawanda dzemaketani ekupedzisira echeni anozadzisa zvinodiwa pamusoro apa. Chimiro chezino chinoshandiswa zvakanyanya i "ma arc matatu nemutsetse mumwe wakatwasuka", kureva kuti, chimiro chezino rekupedzisira chinoumbwa nema arc matatu nemutsetse wakatwasuka.
sprocket
Mativi maviri echimiro chezino pamusoro pemubato we sprocket ane chimiro che arc kuti zvive nyore kupinda nekubuda kwe chain links. Kana chimiro chezino chikagadziriswa nezvishandiso zvakajairika, hazvidikanwi kudhirowa chimiro chezino rekupedzisira padhirowa rekushanda re sprocket, asi chimiro chezino repamusoro pemubato we sprocket chinofanira kudhirowa kuti chiite kuti sprocket itenderere. Ndokumbirawo mutarise bhuku rekugadzira rakakodzera kuti muwane zviyero zve shaft surface tooth profile. Mazino e sprocket anofanira kunge aine simba rakakwana rekubata uye anodzivirira kupfeka, saka pamusoro pezino kazhinji anogadziriswa nekupisa. Sprocket diki ine nguva yakawanda ye meshing kupfuura sprocket hombe, uye simba rekurova rakakurawo, saka zvinhu zvinoshandiswa zvinofanira kunge zviri nani pane zve sprocket hombe. Zvinhu zvinoshandiswa zvakanyanya sprocket isimbi ye carbon (yakadai se Q235, Q275, 45, ZG310-570, nezvimwewo), grey cast iron (yakadai se HT200), nezvimwewo. Sprockets dzakakosha dzinogona kugadzirwa nesimbi ye alloy. Sprocket ine dhayamita diki inogona kugadzirwa kuita mhando yakasimba; chipunu chine dhayamita yepakati chinogona kugadzirwa kuita mhando ye orifice; chipunu chine dhayamita yakakura chinogona kugadzirwa semhando yakabatana. Kana mazino akakundikana nekuda kwekusakara, giya remhete rinogona kutsiviwa. Saizi yehubhu re sprocket inogona kureva pulley.
