Dec 24, 2019 4.The temperature rise of the bearing bush due to the small gap of the tile mouth. The idler bearing is used for a long time, and the contact angle between the bearing and the shaft will become larger and larger due to friction. At the same time, the contact gap between the bearing and the shaft will become smaller and smaller to a certain extent.
3 for ball bearings 10/3 for roller bearings, as used typically in axlebox applications The basic rating life for a specific bearing is based on the basic dynamic load rating according to ISO 281 . The equivalent bearing load has to be calculated based on the bearing loads acting on the bearing via the wheelset journal and the axlebox housing .
Oct 15, 2020 The bush should be installed on the sector block of lower bearing seat according to the rotation direction of ball mill. The bush should be revised according to the axial guide ring. The bearing seat seal should be installed correctly. The junction should be sealed by a sealant.
In our company, this series of high-efficiency ball mill adopts rolling bearing support instead of sliding bearing support with bearing bush. Therefore, it can save energy by 10-20%. According to different discharging ways, it can be divided into two kinds, grate type and overflow type.
