  3. 17. Dimensioning of a cutter wheel bearings

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : Kebin Xie; [2020]
    Keywords : cutter wheel; bearing; wear; scuffing; Archard equation; lubrication number; Reynold equation; Hertzian contact theory; impact load factor; FE model; Ansys; contact pressure on bearing;

    Abstract : Mobile Miner 40V is a machine used for rock excavation and developed by Epiroc. This machine is equipped with a large cutter wheel to perform the excavation. After a test run, some surfaces associated with bearings within the cutter wheel were found to be damaged due to scuffing - severe sliding wear. READ MORE
