The invention relates to a roller gap adjusting mechanism for a guiding and guarding device for a rolling mill. The roller gap adjusting mechanism comprises a lower guide roller support, a lower guide roller, an upper guide roller support and an upper guide roller. The two ends of the lower guide roller support are connected with bottom end bearing seats.

Axial tapered roller bearings, double row tapered roller bearings and axial spherical roller bearings are used mainly in blooming mills, heavy plate mills and hot strip mills, where considerable axial forces occur in combination with low to moderate speeds. During operation, only one bearing row is subjected to pure axial load.

If no abnormality is found, the second check time can be extended, for example, after every 2000h or more, from the rolling mill Remove the bearing and bearing seat and other components, check the working condition, and record the bearing position and bearing area of the rolling mill each time.

Rolling bearings . Principles of rolling bearing selection . General bearing knowledge . Bearing basics . ... SKF recommends applying a cover with a centring spigot that is appropriate to the widths of the bearing and the housing seat. ... In the majority of rolling mill applications, the direction of a radial load is constant. ...

Excessive axial force is an important problem affecting product quality in Shaogang 3450mm plate rolling mill. In order to solve this problem, In order to solve this problem, this paper analyzes the impact of bearing seat clearance on the axial force. Based on the actual measurement of the unit bearing seat clearance, the unit system dynamics model was established, and on this basis, …

A rolling bearing is a precision mechanical component that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. The rolling bearing is generally composed of an inner ring, an outer ring, a …

Three layers of cylindrical roller thrust bearing comprise three seat rings 1, three blowout patches 2, three retainers 3, cylindrical roller 4, outer ring spacer 5, cone spacer 6.The working surface of described three seat rings 1 and three blowout patches 2 is planar surface, three retainers 3 all adopt special-shaped solid cage (see figure 2), all lay 12 row cylinder rollers 4 on the ...

(1) Subjected to high unit pressure,Due to the outer dimension of the bearing seat is restricted, it cannot be larger than the minimum diameter of the roll body, and the length of the roll neck is short, so the unit load on the bearing is large.In general, the unit pressure of rolling mill bearings is as high as 2000-4800mpa, which is 2-5 times ...

In short, the fault causes of mill bearings are very complex, and the common faults and causes are analyzed as follows. 1.1 Fatigue peeling . The inner and outer raceways and the surface of the rolling body of the rolling bearing bear …

The gantry horizontal double active rolling mill set is composed of two active rolling mills. The installation mode and structure of the two rolling mills are the same. The main transmission part adopts the structural form of "motor → reducer → cardan shaft → rolling mill".

The type is the bearing seat of mill work roll intermediate roll support roll, and can also accept other non-standard customizing from customers. Material: working roll (forgings):45 steel,40Cr,42CrMo support roll (castings): zg310-570, zg270-500.

To solve the problems of difficult fault signal recognition and poor diagnosis effect of different damage in the same position in rolling mill bearing at low speed, a fault diagnosis method of rolling mill bearing based on integration of EEMD and DBN was proposed. The vibration signals in horizontal, axial, and vertical directions were decomposed and …
