Abstract
The utility model relates to a novel four-row cylindrical roller bearing with retainer ring internal diameter 320, which comprises two double-row outer rings, two double-row inner rings, two outer rings and two outer rings with two edge retainer rings, wherein 1 middle retainer ring is arranged between the two outer rings, a plurality of rollers are arranged between the outer rings and the inner rings, and the rollers are supported by a support holder.
Description
The technical field is as follows: a four-row cylindrical roller bearing belongs to an oversize bearing. The bearing is mainly used as a special bearing for a supporting roller and a working roller on a rolling mill in the steel and nonferrous metallurgy industries. Belongs to engineering element bearings (F16C) and metal rolling (B21B).
(II) background technology:
the four-row cylindrical roller bearing for installing the rolling mill supporting roller or the working roller in the prior metallurgical steel and nonferrous industry has the advantages of high rotating speed and large borne impact load due to the fact that the working condition of the bearing is severe, the service life of the bearing is short, the accumulated auxiliary time for roller replacement is long, and the user needs to reduce the use cost and requires the bearing to have a long service life.
(III) the invention content:
the utility model provides a take novel four-row cylindrical roller bearing of retainer ring internal diameter 320, its purpose is exactly for the user provides long-life four-row cylindrical roller bearing. Provides the overall dimension and the structural element value of the novel four-row cylindrical roller bearing.
The utility model is used for bearing model FCDP 6495340. FCDP denotes a double inner race four row cylindrical roller bearing with an outer race having a plain ring. The technical scheme of the utility model is that a non-standard new design in this bearing model is provided.
The technical scheme is as follows:
the novel four-row cylindrical roller bearing with the retainer ring inner diameter 320 is provided with two double-row outer rings 1 and two double-row inner rings 2, wherein the outermost edges of the two double-row outer rings are provided with two edge retainer rings 1a, a middle retainer ring 1b is arranged between the two double-row outer rings, a plurality of rollers 4 are arranged between the double-row outer rings and the double-row inner rings, and the rollers are supported by a strut retainer 5, and the novel four-row cylindrical roller bearing with the retainer rings is characterized in that a scheme of a serial number is provided, and the numerical ranges of the bearing inner diameter D, the bearing outer diameter D, the bearing width T (B), the bearing roller diameter Dw, the roller length L and the number Z of each row of rollers of the serial number 1 are respectively.
TABLE 1
In order to obtain the best effect of the four-row cylindrical roller bearing, the numerical values of the bearing inner diameter D, the bearing outer diameter D, the bearing width T (B), the roller diameter Dw, the roller length L and the number Z of each row of rollers of the novel four-row cylindrical roller bearing with each model in the table 1 are respectively the numerical values of the serial number 1 in the table 2, namely the numerical values of the nominal size and the optimized number of each row of rollers after the tolerance is deleted in the table 1.
TABLE 2
The utility model discloses beneficial effect: the novel four-row cylindrical roller bearing with the retainer ring inner diameter 320 is designed by adopting a rolling bearing limit design method originally invented by a company, and the structural element numerical value of a technical scheme of the bearing model FCDP6495340 is determined.
(IV) description of the drawings
FIG. 1 is a front cross-sectional view of a novel four-row cylindrical roller bearing with retainer ring inner diameter 320
Figure 2 roller 4 shape diagram.
(V) detailed description of the preferred embodiments
As shown in figure 1, the double-row bearing comprises two double-row outer rings 1 and two double-row inner rings 2, wherein the outermost edges of the two double-row outer rings are provided with two side check rings 1a, 1 middle check ring 1b is arranged between the two double-row outer rings, a plurality of rollers 4 are arranged between the double-row outer rings and the double-row inner rings, and the rollers are supported by a strut cage 3. The pillar cage 3 is formed by that an axial through hole is arranged at the center of each roller 4, a pillar 3.1 penetrates through the through hole, and two ends of each pillar are respectively connected with two circular gaskets 3.2.
Referring to the figure 1 and the table 2, the external dimensions of the bearing are that the inner diameter D of the bearing is 320mm, the outer diameter D of the bearing is 475mm, the width T (B) of the bearing is 340mm, (where T is the width of the bearing outer ring component, and B is the width of the bearing inner ring component, which are 340mm, namely T is B), the structural elements of the novel four-row cylindrical roller bearing with the baffle ring determined by the rolling bearing limit design method are shown in the figure 2 and the table 2, the diameter Dw of the roller is 45.5mm, the length L of the roller is 62.4mm, and the number Z of the rollers in each row in the circumferential direction is 26.
