Abstract
The utility model relates to a radial large-size axial bearing rotary supporting plate. The rotary supporting plate comprises a thrust ball bearing, an upper pressing plate, a lower pressing plate and balls, wherein the upper pressing plate and the lower pressing plate are buckled with each other and can relatively rotate; the balls and the thrust ball bearing are buckled between the upper pressing plate and the lower pressing plate; circular holes are formed in the centers of the upper pressing plate and the lower pressing plate; the diameter of the circular hole of the upper pressing plate is the same as that of the inner ring of an upper carrying plate of the thrust ball bearing; the diameter of the circular hole of the lower pressing plate is the same as that of the inner ring of a lower carrying plate of the thrust ball bearing; shield rings are arranged on the inner sides of the upper pressing plate and the lower pressing plate of the rotary supporting plate; the inner sides of the shield rings is in clearance fit with the outer sides of the thrust ball bearing; the balls of the rotary supporting plate are made of GCr 5 materials and arranged into two rings, the number of the balls on the inner ring are 14, and the number of the balls on the outer ring are 22. According to the utility model, the rotary supporting plate is simple in structure and convenient to use, and can be applied in engineering machinery and mining machinery.
Description
Technical field
The utility model relates to a kind of rotary support tray, relates in particular to radially large scale axial carrying rotary support tray.
Background technique
In mechanical rotary support structure, the bearing of the various models in NBS, little for rotatably supported parts, particularly at large-size axis parts radially to this field of bearing support.During axial carrying now supports, although bearing standard part can bearing load, the size of their radially carrying is all limited, and in engineering machinery and mining machinery, much axial load is very large, and they cannot meet the demands.
Model utility content
The utility model, in order to overcome existing deficiency, has proposed radially large scale axial carrying rotary support tray.This rotary support tray is simple in structure, can meet rotatably supported requirement, realizes carrying thrust load in radially large-sized situation simultaneously.
The purpose of this utility model is achieved through the following technical solutions.
The utility model radially large scale axial carrying rotary support tray comprises thrust ball bearing, top board, press table and ball.Described top board and press table fasten, the two can relatively rotate, ball and thrust ball bearing are fastened between top board and press table, the center of top board and press table has circular hole, the upper carrier board inner ring diameter of the Circularhole diameter of top board and thrust ball bearing is identical, and the lower carrier board inner ring diameter of the Circularhole diameter of press table and thrust ball bearing is identical.The top board of described radially large scale axial carrying rotary support tray and the inner side of press table arrange a back-up ring, and the outside of the inner side of back-up ring and described thrust ball bearing adopts Spielpassung.What the ball of described radially large scale axial carrying rotary support tray used is GCr15 material, and the ball between top board and press table is provided with two circles, and inner ring ball number is 14, and outer ring ball number is 22.
Compared with prior art, the beneficial effects of the utility model are:
1, axial carrying capacity strengthens, and by the bearing load together of two circle balls, the ability of bearing thrust load strengthens;
1, strength and stiffness increase, because the radial dimension of large scale axial carrying rotary support tray is radially large, so on end face under identical load condition, the stress and strain of end is all less, is difficult for deformation and fracture, so strength and stiffness increase;
2, simple in structure, easy to use, radially large scale axial carrying rotary support tray is simple in structure, installs and uses all very convenient.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the full sectional drawing of A-A in Fig. 1.
In figure: 1, top board; 2, ball; 3, thrust ball bearing; 4, press table.
Embodiment
As depicted in figs. 1 and 2, it has expressed the radially structure of large scale axial carrying rotary support tray of the utility model, comprises top board 1, ball 2, thrust ball bearing 3 and press table 4.Between the top board 1 of this model utility and press table 4, be to fasten, the two can relatively rotate, and ball 2 and thrust ball bearing 3 are fastened between top board 1 and press table 4.Radially the top board 1 of large scale axial carrying rotary support tray and the inner side of press table 4 arrange a back-up ring, and the outer ring of the inner side of back-up ring and described thrust ball bearing 3 adopts Spielpassung.What radially the ball 2 of large scale axial carrying rotary support tray used is GCr15 material, and the ball 2 between top board 1 and press table 4 is provided with two circles, and inner ring ball 2 numbers are 14, and ball 2 numbers in outer ring are 22.
The utility model radially top board 1 and press table 4 centers of large scale axial carrying rotary support tray has circular hole, the upper carrier board inner ring diameter of the Circularhole diameter of top board 1 and thrust ball bearing 3 is identical, and the lower carrier board inner ring diameter of the Circularhole diameter of press table 4 and thrust ball bearing 3 is identical.Running shaft is through the center hole of top board 1, press table 4 and thrust ball bearing 3, the inner ring transition fit of the upper carrier board of the circular hole of running shaft external cylindrical surface and top board 1 and thrust ball bearing 3, the inner ring Spielpassung of the lower carrier board of the circular hole of running shaft external cylindrical surface and press table 4 and thrust ball bearing 3, running shaft drives the upper carrier board of top board 1 and thrust ball bearing 3 to rotate, thrust load on running shaft is delivered to top board 1 and thrust ball bearing 3, and pressing plate 1 and thrust ball bearing 3 are delivered to thrust load again on ball 2 and press table 4.In the time that radially large scale axial carrying rotary support tray is arranged on the load bearing seat of machinery, thrust load is delivered on load bearing seat by press table 4.Because the radial dimension of large scale axial carrying rotary support tray is radially larger, under very large thrust load, ball 2 bearing load together of two circles, axial carrying capacity strengthens, and radially large scale axial carrying rotary support tray still can ensure very high strength and stiffness.
