Ubulukhuni obungaphezulu nobunyeUkukhokhiswa Shaftyizinto eziphambili zezidingo zobuchwepheshe kanye nokuhlolwa okujwayelekile. Ubulukhuni bomzimba bukhombisa ukumelana nokugqoka, njll., Ekukhiqizweni, i-HSD enezinkampani eziqinile i-HSD isetshenziselwa ukuveza.
Izidingo zobulukhuni bokuthethelelwa kwe-shaft ikakhulukazi kususelwa ku-hardness level of the roller okusebenzayo noma i-roller ephakathi ukuxhumana nayo, futhi bobabili kufanele bagcine ubudlelwano obufanele. Ngokusho kocwaningo nge-Thinta Charkism Mechanism, ubulukhuni be-roller yokusekelwa kufanele kube amayunithi we-10-25 hs aphansi kunalokho kwengxenye yokuxhumana, okuzuzisayo ukuthuthukisa into yokukhathala endaweni yokuxhumana. -GwanyileUkukhokhiswa Shaftube nokumelana okuphansi futhi uthambekele ekuphanjweni kwe- "Peeleng", okungukuthi, ungqimba olungajulile lomkhawulo we-roll surface lukhiqiza i-deformation yepulasitiki bese kukhiqiza inqwaba ebunjiwe; Lapho ubulukhuni buphezulu kakhulu, ithuba lokunyuka kwe-blittle spalling. Njengoba inani le-Fracture Groudness Value lesendlalelo oluqinile liphansi, uma ukuqhekeka kuvela, kuzosabalala ngokushesha, okuholela ekuchithekeni okukhulu kakhulu. Ubulukhuni obuphezulu bungaphinde bangenze ukulimala kokukhathala nokugqoka okusheshayo kweUkukhokhiswa Shaftfuthi unciphise isikhathi sokugayaUkukhokhiswa Shaft.

Eminyakeni yamuva nje, ubulukhuni beUkukhokhiswa ShaftUkugaya okubandayo nokushisayo kuthuthukisiwe, ikakhulukazi ama-rolls omsebenzi wokugoqa okushisayo athuthukisiwe futhi akhuthaza ngokulandelana, izinga lobulukhuni lwe-chromium composite ephezulu ye-chromium cast roll rolls kanye nemibhalo ephezulu yensimbi ebandayo. Izinga lobulukhuniUkukhokhiswa Shaftifinyelele ku-70-83. Imisipha yamanje yokhokhisekayo yokwenziwa kwe-shaft kanye nezobuchwepheshe zokukhiqiza ingakuhlangabezana nobulukhuni bemithi enkulu ye-55-75 yokweqa shaft ephezulu ephezulu. Ngasikhathi sinye, ukusetshenziswa kwe-Hardness Hardness Shaft ephakeme okuthembisa ubuchwepheshe bokulungisa nakho kuqongelele okuhlangenwe nakho okuningi.
SuperUkukhokhiswa okukhulu komgwaqoIsigayo seplate sikhulu ngosayizi futhi sisinda ngesisindo, futhi ijubane lokugoqa lincane kakhulu kunalesosigayo. Ngakho-ke, ukumelana kwe-Wear kanye nezidingo zobulukhuni ziphansi.
