Main shaft :Material is 50Mn high-quality carbon structural simbi, ine C yemukati kubva pa0.48 kusvika 0.56%, Si zvemukati kubva 0.17 kusvika 0.37%, Mn zvemukati kubva 0.7 kusvika 1.0%, S zvemukati kubva pasi pe0.035%, P zvemukati kubva kubva pasi pe0.035%, uye Cr zvinyorwa zvinotangira kubva pasi pe0.25 kusvika ku0.30%, Ni content kubva pasi pe0.30%, uye Cu zvinyorwa kubva pasi pe0.25%.Pakati pavo, Mn chinhu chinokosha mu alloy steel, iyo inogona kuvandudza ductility uye plasticity yezvinhu, simbisa kusimba kwakakwana uye kupfeka kuramba.Mushure mekurapwa kwekupisa, 50Mn simbi ine simba rakakura uye kuoma, kupinza kwakanyanya, kuomarara kwakadzika, uye yakanaka pearlite magadzirirwo, uye kuita kwakanaka kwemichina.
Magadzirirwo magadzirirwo eiyo shaft huru inoda hudzamu hwe2 kusvika 7 mm yekuomarara uye kuomarara kwe50 kusvika 62 HRC.
Muviri :Kuti uvandudze kupfeka kuramba kwetrack roller's muviri, zvinhu ndeye 40Mn2 alloy structural simbi, ine C yemukati kubva 0.37 kusvika 0.44%, Si zvemukati kubva 0.17 kusvika 0.37%, Mn zvemukati kubva 1.4 kusvika 1.8%, P zvemukati kubva pasi pe0.030%, uye S zvemukati kubva kubva pasi pe0.030%.
The pasi rollermuviri unoumbwa nemaitiro ekugadzira.Mushure mekuumbwa, iyo vhiri vhiri muviri unodzikamiswa kuti uwane kuomarara kwe26-32HRC kuchengetedza yakakwira simba, plastiki, kuoma, uye yakazara ma mechanical kuita mukati mevhiri muviri.The vhiri muviri pamusoro ari pasi quenching kurapwa kuwedzera kuomarara uye kupfeka kuramba kwerutsigiro njanji pamusoro.The quenching kuoma ndiko 50-58HRC, pamwe kudzika 6-12mm.Izvi zvinoguma mukufanana kwekutanga pakati pekuomarara kwenjanji uye ketani yekubatanidza kubatana kuoma (48-58HRC).
Chisimbiso:Saizi uye pamusoro roughness pamusoroO-ringinofanira kuenderana nezvinodiwa zvekugadzira.Kubatana kwepamusoro kunofanira kutenderedzwa, uye panofanira kunge kune kucheneswa kwehupi hupi uye mipendero yakapinza.
Inoyangarara seal rabha uye O-ringinofanira kusarudzwa kubva pamhando yepamusoro butyl rubber.Iyo mukati medhayamita, saizi yeshinda, elasticity, kuoma (Shore), uye kupera kwepamusoro kunofanirwa kuenderana nezvinodiwa.Pamberi pekusangana, zvese zviri pamusoro apa zvinofanirwa kuongororwa uye zvinokodzera zvinoenderana nemazinga ari pamusoro apa isati yaiswa.
Gap :Iyo clearance pakati peaxle main axis uye hub inotakura panerollermuviri unofanirwa kuva 0.2-0.4 mm.Paunotenderera, hapafaniri kuva nekuvharadambudzikouye kuita kwakanaka kwekuisa chisimbiso, hapana kubuda kwemafuta.
Lubrication :Mafuta ekubereka mutrack rollr inofanira kuiswa jekiseni uchishandisa pombi yemafuta.Kana zvichidikanwa, mafuta ekuzora viscosity anogona kuwedzerwa zvakakodzera.Usati wabaya mafuta ekubereka, mafuta akasakara anofanira kubudiswa kunze.Zvadaro, mafuta matsva anofanira kuwedzerwa kugomba repureji yemafuta kusvikira mafuta abuda.Paunenge uchibaya mafuta ekuzora, hub cap screw inofanira kubviswa, uye kuguma kwemafuta kwechigadziro chemafuta kunofanira kudzvinyirirwa pafudzi mumugero wemafuta.Kusimbisa torque yepulagi yemafuta inofanira kudzorwa pakati pe157-255 Nm.
