Abstract

The utility model discloses a novel bearing end cover sealing strip anti-rotating structure which comprises a bearing end cover. The bearing end cover is composed of an upper end cover and a lower end cover. The upper end cover is fixedly connected with the lower end cover through a bolt. The inner side wall of the upper end cover and the inner side wall of the lower end cover are respectively provided with a plurality of arc grooves. The arc grooves of the upper end cover vertically correspond to the arc grooves of the lower end cover in a one-to-one mode. An annular groove is formed by each arc groove of the upper end cover and the corresponding arc groove of the lower end cover. A sealing ring is inlaid in each annular groove. An axial groove is formed in the upper top face of the lower end cover and communicated with the annular grooves. A gap is formed in the back face, at the axial groove, of each sealing ring. A pressing plate is inserted into the axial groove in a sleeved mode and fixedly connected to the bottom face of the axial groove through a screw. The lower bottom face of the gap of each sealing ring is located below the pressing plate. The novel bearing end cover sealing strip anti-rotating structure is simple and compact, the rotation, caused by looseness of the bearing end cover sealing rings, of the bearing end cover sealing rings along with a rotating shaft can be prevented, and the sealing effect is ensured.

Description

A kind of novel bearing end bracket enclosed bar anti-rotation structure

Technical field:

The utility model relates to technical field of bearings, relates in particular a kind of novel bearing end bracket enclosed bar anti-rotation structure.

Background technique:

Sliding bearing is very extensive in the application of all trades and professions, and along with the continuous expansion of sliding bearing application and the continuous progress of technology, the structure of sliding bearing also becomes increasingly complex.Often need to bear certain high rotating speed as some for sliding bearings such as generator, blower fan, gear-boxes, be generally 3000r/min and more than.Owing to working as, axle rotating speed is higher, and the frictional force at axle and bearing (ball) cover Stamping Steel Ribbon place will be larger, and bearing (ball) cover seal ring easily becomes flexible and rotates along axle sense of rotation, reduces the effect of sealing.

Model utility content:

The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of novel bearing end bracket enclosed bar anti-rotation structure is provided, and it is simple and compact for structure, can prevent that bearing (ball) cover seal ring from becoming flexible and along with rotatingshaft rotates, ensureing sealing effect.

The scheme that the utility model solve the technical problem is:

A kind of novel bearing end bracket enclosed bar anti-rotation structure, comprise bearing (ball) cover, bearing (ball) cover is made up of upper end cap and lower end cap, together with upper end cap is bolted on lower end cap, on the madial wall of described upper end cap and lower end cap, all form multiple arc grooves, the arc groove of upper end cap is corresponding one by one up and down with the arc groove of lower end cap, the arc groove makeup ring connected in star of the arc groove of upper end cap and the lower end cap corresponding with it, and seal ring is embedded in annular groove;

On the upper end face of lower end cap, form axial notch, axial notch communicates with annular groove, seal ring is jagged at the bead formed on back of axle phase groove, pressing plate sleeve is in axial notch and be fixedly connected on by screw on the bottom surface of axial notch, and the bottom surface of the breach of seal ring is below pressing plate.

The cross section of described arc groove is trapezoidal faces; Ring structure is that cross section is on the madial wall of annular ring of trapezoidal faces, to be extended with protruding circle portion, and annular ring is embedded in annular groove.

The bottom surface of described breach and the bottom surface of axial notch are in same level, and the upper end face of breach is higher than the upper end face of lower end cap.

Outstanding effect of the present utility model is:

Compared with prior art, it is simple and compact for structure, can prevent that bearing (ball) cover seal ring from becoming flexible and along with rotatingshaft rotates, ensureing sealing effect.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the structural representation of seal ring;

Fig. 4 is the partial structurtes schematic diagram between seal ring, lower end cap and pressing plate.

Embodiment:

Embodiment, see as shown in Figures 1 to 4, a kind of novel bearing end bracket enclosed bar anti-rotation structure, comprise bearing (ball) cover 10, bearing (ball) cover 10 is made up of upper end cap 11 and lower end cap 12, together with upper end cap 11 is bolted on lower end cap 12, on the madial wall of described upper end cap 11 and lower end cap 12, all form multiple arc grooves 13, the arc groove 13 of upper end cap 11 is corresponding one by one up and down with the arc groove 13 of lower end cap 12, the arc groove 13 makeup ring connected in stars 20 of the arc groove 13 of upper end cap 11 and the lower end cap 12 corresponding with it, seal ring 2 is embedded in annular groove 20,

On the upper end face of the both sides of lower end cap 12, all form axial notch 3, axial notch 3 communicates with annular groove 13, seal ring 2 is at the bead formed on back jagged 21 at axle phase groove 3 places, pressing plate 4 sleeves are in axial notch 3 and be fixedly connected on by screw 5 on the bottom surface of axial notch 3, and the bottom surface 211 of the breach 21 of seal ring 2 is below pressing plate 4.

The cross section of described arc groove 13 is trapezoidal faces; Seal ring 2 structures are that cross section is on the madial wall of annular ring 22 of trapezoidal faces, to be extended with protruding circle portion 23, and annular ring 22 is embedded in annular groove 13.

The bottom surface 211 of described breach 21 is with the bottom surface of axial notch 3 in same level, and the upper end face of breach 21 is higher than the upper end face of lower end cap 12.

By the pressing plate 4 connecting in an axial notch 3, seal ring 2 is carried out to ways to restrain seal ring 2 because phenomenon loosening and that rotate along with rotatingshaft produces, ensure the effect of sealing.

It is the axial notch 3 of an installation pressing plate 4 of the each milling in end face place on the left and right of lower end cap 12 while installation, and seal ring 2 is embedded in annular groove 13, and then seal ring 2 is processed to form to breach 21 at the back side at axle phase groove 3 places.By screw 5, pressing plate 4 is fixed on axial notch 3, seal ring 2 is fixed on lower end cap 12 by pressing plate 4 like this.Therefore the utility model also has the feature of easy accessibility.
