Description

The Jing Yin bearing of one kind sealing

Technical field

The utility model is related to field of mechanical technique, is specially a kind of Jing Yin bearing of sealing.

Background technology

Bearing is a kind of important spare part in contemporary plant equipment.Its major function is the mechanical rotary body of support, reduction Coefficient of friction in its motion process, and ensure under its rotating accuracy, prior art, bearing especially rolling bearing, its noise It is larger, the noise that the friction belt of the source of its noise between inner ring, steel ball ball and outer ring is come, substantial amounts of noise Influence to environment is fairly obvious, and the ball of exposure easily adsorbs substantial amounts of dust, influences the normal rotation of ball, increase Rolling friction, therefore, we have proposed the Jing Yin bearing of one kind sealing.

Utility model content

The purpose of this utility model is to provide a kind of Jing Yin bearing of sealing, to solve the axle proposed in above-mentioned background technology Especially rolling bearing is held, its noise is larger, source the rubbing between inner ring, steel ball ball and outer ring of its noise The noise brought is wiped, the influence of substantial amounts of NOISE ON ENVIRONMENT is fairly obvious, and the ball of exposure easily adsorbs substantial amounts of dust, Influence the problem of normal rotation of ball, increase rolling friction.

To achieve the above object, the utility model provides following technical scheme：The Jing Yin bearing of one kind sealing, including outer ring, The inwall of the outer ring is uniformly provided with five groups of annular ball grooves, and the right side wall of the outer ring is provided with axis hole, the center of circle of the axis hole Place is overlapped with the center of circle of outer ring right side wall, caulking groove is provided with the left of the outer ring inwall, the inner chamber transverse splicing of the outer ring has Uniform on inner ring, the inner ring to be provided with ball, the position of the ball is corresponding with the position of annular ball grooves, the inner ring Inwall be provided with five groups of ball mounting holes, the ball is arranged between annular ball grooves and ball mounting hole, the inner ring Left and right ends are respectively connected with baffle plate, and the left side wall of the outer ring is provided with limiting retainer ring, and the limiting retainer ring is by caulking groove and outside Circle connection, the two ends of the limiting retainer ring are provided with gripping hole.

It is preferred that, the inner diameter of the axis hole is identical with the inner diameter of inner ring, and the outer diameter of the baffle plate is less than The inner diameter of outer ring.

It is preferred that, the limiting retainer ring is integrally formed with gripping hole, and the limiting retainer ring is elastic steel sheet collar.

It is preferred that, the inwall of the annular ball grooves and ball mounting hole is plated with wearing layer, and wearing layer is nickel plating Layer.

Compared with prior art, the beneficial effects of the utility model are：The Jing Yin bearing of the sealing, by the way that ball is arranged on Between outer ring and inner ring, during filling lubricating oil, the leakage of lubricating oil is reduced, by the setting of baffle plate, dust adsorption is reduced to rolling On pearl, increase bearing service life, will be separated by ball mounting hole and annular ball grooves between ball, reduce collision and produce Noise.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.

Fig. 1-4 are referred to, the utility model provides a kind of technical scheme：The Jing Yin bearing of one kind sealing, including outer ring 1, outside The inwall of circle 1 is uniformly provided with five groups of annular ball grooves 2, and the right side wall of outer ring 1 is provided with axis hole 3, circle centre position and the outer ring 1 of axis hole 3 The center of circle of right side wall is overlapped, and is provided with caulking groove 4 on the left of the inwall of outer ring 1, the inner chamber transverse splicing of outer ring 1 has on inner ring 5, inner ring 5 Uniform to be provided with ball 6, the position of ball 6 is corresponding with the position of annular ball grooves 2, and the inwall of inner ring 5 is provided with five groups of balls Mounting hole 7, ball 6 is arranged between annular ball grooves 2 and ball mounting hole 7, and the left and right ends of inner ring 5 are respectively connected with baffle plate 8, The left side wall of outer ring 1 is provided with limiting retainer ring 9, and limiting retainer ring 9 is connected by caulking groove 4 with outer ring 1, and the two ends of limiting retainer ring 9 are equal It is provided with gripping hole 10.

Wherein, the inner diameter of axis hole 3 is identical with the inner diameter of inner ring 5, installation when being easy to use, outside baffle plate 8 Wall diameter is less than the inner diameter of outer ring 1, it is to avoid ball 6 can not be rotated, and limiting retainer ring 9 is integrally formed with gripping hole 10, spacing Collar 9 is elastic steel sheet collar, and the inwall of annular ball grooves 2 and ball mounting hole 7 is plated with wearing layer, and wearing layer is plating Nickel dam, increases service life.

Operation principle：Ball 6 and ball mounting hole 7 are corresponded into installation, after installation, inner ring 5 is inserted in outer ring 1, Ball 6 is stuck in annular ball grooves 2, and gap is left between the right side wall of right-hand apron 8 and outer ring 1, it is to avoid laminating produces larger Frictional force, is inserted in two groups of gripping holes 10 using two terminations of tweezers, is clutched and is embedded in limiting retainer ring 9 in caulking groove 4 and pine Open so that limiting retainer ring 9 blocks inner ring 5, it is to avoid inner ring 5 comes off when using, baffle plate 8 avoids dust from entering outer ring 1 and inner ring 5 Between, and it is capable of the unofficial biography of blocking noise, it is engaged correspondingly with ball 6 by ball mounting hole 7, when reducing by 6 rotation Larger collision is produced with outer ring 1 or inner ring 5.

While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out in the case where not departing from principle of the present utility model and spirit a variety of changes, repaiies Change, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
