Uthumelo lwetyathanga luthumelo lwe-meshing, kwaye umlinganiselo ophakathi wothumelo uchanekile. Luthumelo lwe-mechanical oludlulisela amandla kunye nentshukumo ngokusebenzisa uthumelo lwetyathanga kunye namazinyo e-sprocket.
itsheyini
Ubude betyathanga buchazwa ngenani leekhonkco. Inani leekhonkco zetyathanga kungcono libe linani elilinganayo, ukuze xa ityathanga liqhagamshelwe kwiringi, ipleyiti yetyathanga yangaphandle kunye nepleyiti yetyathanga yangaphakathi ziqhagamshelwe nje, kwaye amalunga anokutshixwa ngee-spring clips okanye ii-cotter pin. Ukuba inani leekhonkco aliqhelekanga, kufuneka amakhonkco otshintsho. Xa ityathanga liphantsi koxinzelelo, ikhonkco lotshintsho likwathwala imithwalo eyongezelelweyo yokugoba kwaye kufuneka liphetshwe ngokubanzi. Ityathanga elinamazinyo lenziwe ngamapleyiti amaninzi etyathanga elinamazinyo adibeneyo aqhagamshelwe zii-hinges. Ukuze kuthintelwe ukuwa kwetyathanga xa lixutywa, ityathanga kufuneka libe nepleyiti yesikhokelo (eyahlulwe ngohlobo lwesikhokelo sangaphakathi kunye nohlobo lwesikhokelo sangaphandle). Amacala amabini epleyiti yetyathanga elinamazinyo angamacala athe tye, kwaye icala lee-meshes zetyathanga kunye neprofayili yamazinyo e-sprocket ngexesha lokusebenza. I-hinge ingenziwa ibe yi-sliding pair okanye i-rolling pair, kwaye uhlobo lwe-roller lunokunciphisa ukungqubana kunye nokuguguleka, kwaye isiphumo singcono kunesohlobo lwe-bearing pad. Xa kuthelekiswa nee-roller chains, ii-toothed chains zihamba kakuhle, zinengxolo ephantsi, kwaye zinamandla aphezulu okumelana nemithwalo yempembelelo; kodwa izakhiwo zazo ziyinkimbinkimbi, zibiza kakhulu, kwaye zinzima, ngoko ke ukusetyenziswa kwazo akubanzi njengee-roller chains. Ii-toothed chains zisetyenziselwa kakhulu isantya esiphezulu (isantya se-chain ukuya kuthi ga kwi-40m/s) okanye ukuhanjiswa kwentshukumo echanekileyo. Umgangatho wesizwe uchaza kuphela amaxabiso aphezulu kunye namancinci e-arc radius yomphezulu wezinyo, i-arc radius ye-arc ye-tooth groove kunye ne-angle ye-tooth groove ye-tooth groove ye-roller chain sprocket (jonga i-GB1244-85 ngeenkcukacha). Iprofayili yobuso bokwenyani be-sprocket nganye kufuneka ibe phakathi kweempawu ezinkulu nezincinci ze-cogging. Olu nyango luvumela ukuguquguquka okukhulu kuyilo lwe-sprocket tooth curve. Nangona kunjalo, i-tooth shape kufuneka iqinisekise ukuba i-chain ingangena kwaye iphume i-meshing kakuhle nangokukhululekileyo, kwaye kufuneka kube lula ukuyicubungula. Kukho iintlobo ezininzi zee-end tooth profile curves ezihlangabezana neemfuno ezingentla. I-tooth shape esetyenziswa kakhulu yi-"three arcs kunye ne-one straight line", oko kukuthi, i-end face tooth shape yenziwe ngee-arcs ezintathu kunye ne-straight line.
i-sprocket
Amacala omabini emilo yezinyo kumphezulu we-sprocket shaft amile okwe-arc ukuze kube lula ukungena nokuphuma kweekhonkco zetyathanga. Xa imilo yezinyo icutshungulwa ngezixhobo eziqhelekileyo, akufuneki ukuba uzobe imilo yezinyo ekupheleni kobuso kumzobo osebenzayo we-sprocket, kodwa imilo yezinyo lomphezulu we-sprocket shaft kufuneka itsalwe ukuze kube lula ukujika kwe-sprocket. Nceda ujonge incwadi yemiyalelo efanelekileyo yoyilo malunga nobukhulu obuthile beprofayili yezinyo lomphezulu we-shaft. Amazinyo e-sprocket kufuneka abe namandla aneleyo okunxibelelana kunye nokumelana nokuguguleka, ngoko ke imiphezulu yezinyo iphathwa kakhulu ngobushushu. I-sprocket encinci inamaxesha amaninzi okutsala kune-sprocket enkulu, kwaye amandla okubetha nawo makhulu, ngoko ke izinto ezisetyenzisiweyo kufuneka zibe ngcono kunezo ze-sprocket enkulu. Izinto ze-sprocket ezisetyenziswa rhoqo yi-carbon steel (ezifana ne-Q235, Q275, 45, ZG310-570, njl.njl.), i-grey cast iron (ezifana ne-HT200), njl. Ii-sprocket ezibalulekileyo zingenziwa ngentsimbi ye-alloy. I-sprocket enobubanzi obuncinci inokwenziwa ibe luhlobo oluqinileyo; i-sprocket enobubanzi obuphakathi ingenziwa ngohlobo lwe-orifice; i-sprocket enobubanzi obukhulu inokwenziwa ngohlobo oludibeneyo. Ukuba amazinyo ayasilela ngenxa yokuguguleka, igiya yeringi inokutshintshwa. Ubungakanani be-sprocket hub bungabhekisa kwi-pulley.
