What is a backing bearing? Mounting and dismounting of backing bearings? The backing cylindrical roller bearing is lubricated with oil water mixed emulsion (8~12cst/40 DEG C), and the oil is injected into the bearing by the oil hole and shaft groove in the axle, so that the finished product can not be polluted. In addition, when the outer diameter of the outer ring which is directly contacted with the roller is rough, as long as a certain amount of grinding is carried out on the outer diameter, the utility model can be used again.
The rolling mill backing bearing is a precise mechanical component, which must be precisely matched when applied so as to achieve the best operation function. When new requirements are put forward for the mill backing bearing, the design of the bearing layout needs more detailed technical parameters.
Mounting and dismounting of backing bearings?
The inner bearing of the back bearing bear the point load, and when the shaft is installed, loose fit is adopted. Note that some of the backing bearings are not self retaining. To prevent rolling bodies from falling, the inner ring cannot be pushed out during adjustment. The bearing assembly can not be split or interchanged during installation and disassembly.
Section height grouping: reducing the tolerance of rolled materials requires high bearing accuracy, especially for the outer ring runout and the cross sectional tolerance of the bearings. This is achieved by classifying highly demanding manufacturing tolerances and tolerances of each component.
Maintenance of backing bearings
The backing bearing must be checked after a certain period of time. The bearings need to be removed from the shaft to check for damage. |
