Grinding roller-bearing arrangement for bearing shaft element relative to grinding roller of mill, has distance ring arranged between bearing outer rings, and floating bearing arranged with axial distance from roller bearings in roller

摘要

The arrangement (1) has a fixed bearing point (4) including two taper roller bearings (5, 6) forming a unit. One of the bearings (5) with a high load rating includes a taper angle, which is larger than a taper angle of the other bearing (6) with a small load rating. Bearing inner rings (7, 8) of the bearings lie adjacent to each other in an X-arrangement of the bearings. A distance ring (11) with a defined axial extension is arranged between the bearing outer rings (9, 10). A floating bearing (12) is arranged with an axial distance (a) from the roller bearings in grinding roller (3). The floating bearing is a cylinder roller bearing.
