Abstract
The utility model discloses a double-row taper roller bearing used for a grinding roll of a vertical roller mill, which comprises an outer ring and an inner ring, wherein the outer ring is formed by two discrete single-row outer rings, and the inner ring is formed by two discrete single-row outer rings. The double-row taper roller bearing further comprises a retainer which comprises two discrete single-row retainers, and hoisting holes formed on the end faces of the outer ring and the inner ring respectively. A spacer ring is arranged between the two single-row outer rings. The double-row taper roller bearing has higher rated carrying capacity and good impact resistance, and provides convenience for installation and clearance adjustment.
Description
Technical field
The utility model relates to design bearing and manufacturing technology field, particularly a kind of vertical roll grinder grinding roller double-row conical bearing.
Background technique
Vertical roll grinder grinding roller bearing is one of vital part of vertical roll grinder, directly affects the level of main frame, and is very high to the life-span and the reliability requirement of bearing, and bearing adopts roller bearing to add the collocation form of double-row conical bearing.Wherein double-row conical bearing is because of stressed bigger, and impulsive load is arranged, and this bearing load carrying capacity and impact resistance are lower; In addition, the weight of bearing is bigger, and the adjustment of installation, play is very inconvenient.
The model utility content
The purpose of this utility model provides a kind of vertical roll grinder grinding roller double-row conical bearing, can bear bigger specified bearing capacity and favorable shock resistance, and installation and play are adjusted very convenient.
The utility model has adopted following technological scheme: a kind of vertical roll grinder grinding roller double-row conical bearing, comprise outer ring and inner ring, described outer ring is made of two discrete single-row outer rings, inner ring is made of two discrete single-row inner rings, described retainer is two discrete single-row retainers, in the outer ring, the inner ring end face respectively is provided with erection opening.
Be provided with spacer ring between described two single-row outer rings.
Described erection opening in the outer ring, the inner ring end face respectively is provided with 2 up and down.
Owing to adopted above-mentioned technological scheme, the utlity model has following superiority:
1, the application of this bearing can effectively improve the life-span and the reliability of vertical roll grinder grinding roller bearing, has good market prospects.
2, this bearing has bigger specified bearing capacity and favorable shock resistance.
3, between 2 single-row outer rings, dispose spacer ring, conveniently be used to adjust the axial internal clearance of bearing.
4, this bearing adopts split-type structural, and is provided with erection opening on the inner ring of bearing, cycle surface, makes the installation of bearing and play adjust very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Vertical roll grinder grinding roller double-row conical bearing as shown in Figure 1, comprise outer ring 1 and inner ring 2, described outer ring 1 is made of two discrete single-row outer rings, inner ring 2 is made of two discrete single-row inner rings, described retainer 4 is two discrete single-row retainers, between two single-row outer rings, be provided with spacer ring 5, in the outer ring, the inner ring end face respectively is provided with up and down two erection opening 6, is convenient to the installation and the play adjustment of bearing.
Bearing inner race and grinding roller are bigger interference fit during installation, and the original play of rear bearing is installed can change, must be by being adjusted to negative play state after installing.
The utility model can be used for the ZRM3640 vertical roll grinder, and bearing accuracy is the P5 level, and radially dynamic load rating is 6200kN.
