(1) Musiyano mukuru pakati pemidziyo yesimbi inoshandiswa kune zvikamu zveketani kumba nekune dzimwe nyika zviri mukati uye kunze kwecheni mahwendefa.Kuita kweplate yeketani kunoda kusimba kwakanyanya uye kumwe kuoma.MuChina, 40Mn uye 45Mn anowanzo shandiswa kugadzira, uye makumi matatu neshanu simbi haiwanzo kushandiswa.Iyo kemikari ye40Mn uye 45Mn simbi mahwendefa yakakura kupfuura iyo yekunze S35C uye SAEl035 masimbi, uye pane 1.5% kusvika 2.5% ukobvu decarburization pamusoro.Nokudaro, ndiro yeketani inowanzotambura nekuputsika kwebrittle mushure mekudzima uye kukwana kwakakwana.
Munguva yekuomarara bvunzo, kuomarara kwepamusoro kwendiro yeketani mushure mekudzima kwakadzikira (pasi pe40HRC).Kana humwe hukobvu hwepamusoro hwakapfekwa, hurema hunogona kusvika kupfuura 50HRC, izvo zvinozokanganisa zvakanyanya hudiki hwekuremerwa kwecheni.
(2) Vagadziri vekunze vanowanzo shandisa S35C uye SAEl035, uye vanoshandisa yakawedzera kuenderera mberi mesh bhandi carburizing mavira.Munguva yekurapa kwekupisa, mhepo yekudzivirira inoshandiswa pakurapazve recarburization.Uye zvakare, kuomesera pa-saiti maitiro ekudzora anoitwa, saka macheni mahwendefa haawanzo kuitika.Mushure mekudzima uye kupisa, brittle kutyoka kana kuderera kwepamusoro kuoma kunoitika.
Metallographic observation inoratidza kuti pane yakakura yeakanaka tsono-yakafanana martensite chimiro (anenge 15-30um) pamusoro pecheni ndiro mushure mekudzima, nepo musimboti uri strip-like martensite chimiro.Pasi pemamiriro ehumwe chain plate ukobvu, hushoma hutete hwekuremerwa mushure mekupisa hwakakura kupfuura hwezvigadzirwa zvemumba.Munyika dzekunze, 1.5mm makobvu mahwendefa anowanzo shandiswa uye simba rinodiwa rinoita > 18 kN, nepo cheni dzemumba dzichiwanzoshandisa 1.6-1.7mm mahwendefa akakora uye simba rinodiwa rinoita> 17.8 kN.
(3) Nekuda kwekuenderera mberi kwekuvandudzwa kwezvinodiwa zvezvikamu zveketani yemudhudhudhu, vagadziri vepamba nevekunze vanoenderera mberi nekuvandudza simbi inoshandiswa pamapini, maoko uye rollers.Iyo shoma inorema mutoro uye kunyanya kupfekedza kuramba kweketani kunoenderana nesimbi.Mushure mekunge vagadziri vepamba nevekunze vachangobva kusarudza 20CrMnTiH simbi sechinhu chepini pachinzvimbo che20CrMnMo, chain tensile load yakawedzera ne13% kusvika 18%, uye vagadziri vekunze vakashandisa SAE8620 simbi sepini uye sleeve zvinhu.Izvi zvakare zvinoenderana neizvi.Kudzidzira kwakaratidza kuti chete nekuvandudza gaka rakakodzera pakati pepini uye sleeve, kuvandudza kupisa kwekupisa uye lubrication, iyo inogona kupfekedzwa kuramba uye kutakura mutoro wecheni kuvandudzwa zvakanyanya.
(4) Muzvikamu zvecheni yemudhudhudhu, ndiro yemukati yekubatanidza uye sleeve, yekunze link plate nepini zvese zvakanamirwa pamwe chete nekupindirana kwekupindirana, nepo pini nesleeve zviri clearance fit.Iyo inokwana pakati pezvikamu zveketani ine simba guru pakuramba kupfeka uye kushomeka kwekutakura mutoro wecheni.Maererano nezviitiko zvakasiyana-siyana zvekushandisa uye kukuvadza mitoro yeketani, yakakamurwa kuva nhanho nhatu: A, B uye C. Kirasi A inoshandiswa kune inorema-basa, yakakwirira-kumhanya uye yakakosha kutapurirana;Kirasi B inoshandiswa kune general transmission;Kirasi C inoshandiswa kune zvakajairika kuchinja giya.Naizvozvo, izvo zvinodikanwa zvekubatanidza pakati peKirasi A cheni zvikamu zvakaomarara.
