Abstract

The utility model discloses a vibration-reduction sealing bearing. The bearing comprises an outer circle (1), an inner circle (2) and a rolling body (3), wherein the rolling body (3) is arranged between the outer circle (1) and the inner circle (2) in a rolling way. The bearing is characterized in that a rubber ring (4) is covered between the outer circle (1) and the inner circle (2) on one end surface of the vibration-reduction sealing bearing. Compared with the prior art, the rubber ring is covered between the outer circle and the inner circle on one end surface of the vibration-reduction sealing bearing, so that the vibration-reduction effect is good, the dust can be prevented from entering the inner cavity of the bearing, and the sealing effect is achieved; and furthermore, a gap is preserved between the periphery of the rubber ring and the inner circumference of an outer circle table-level circle to prevent the generation of friction resistance when the rubber ring is in contact rotation with the outer circle of the bearing, so that the flexibility of the rotation of the bearing is maintained. Therefore, the bearing disclosed by the utility model is a simple and practical product which is smart in design and worthy of popularizing.

Description

The vibration damping stuffing box bearing

Technical field

The utility model relates to a kind of bearing manufacture technology field, especially refers to a kind of vibration damping stuffing box bearing.

Background technique

Existing a kind of patent No. is that the Chinese utility model patent that the CN200820081224.X name is called " vibration and noise reducing bearing " discloses a kind of vibration and noise reducing bearing, comprise inner ring, outer ring and place rolling element between them, it is characterized in that rolling element by two with central through bore and small end interior, large end solid of rotation outside consists of, inner ring outer surface, inner surface be provided with rolling element matched with cavity protruding, concave surface.Can easily rolling element be installed in the cavity between the inside and outside circle of bearing, and assembling, dismounting are quite convenient, have solved behind the existing bearing assemble because existing radial internal clearance to produce the problem of vibration and noise.But this vibration and noise reducing associated sealing arrangement for bearings complex structure, manufacture difficulty is relatively large, so this structure awaits to improve.

The model utility content

Technical problem to be solved in the utility model is a kind of reasonable in design, simple in structure, good damping result to be provided for above-mentioned prior art present situation and can to prevent effectively that dust from entering the vibration damping stuffing box bearing of bearing cavity.

The utility model solves the problems of the technologies described above the technological scheme that adopts: this vibration damping stuffing box bearing, include outer ring, inner ring and rolling element, described rolling physical efficiency rollably places between outer ring and the inner ring, it is characterized in that: lid is equipped with rubber ring between the outer ring of described vibration damping stuffing box bearing one end face and inner ring.

As improvement, described cycle surface is provided with the platform level circle of annular, and the outer border of described rubber ring is held in the platform level circle of outer ring.

As improvement, leave the space between the inner peripheral surface of the outer circumferential face of described rubber ring and platform level circle.

As improvement, described rubber ring and inner ring can be preferably the integrative-structure that mold pressing forms.

Improve, described rubber ring and inner ring may be selected to be the bonding integrative-structure that forms again.

Improve, the upper-end surface of described rubber ring is the upper-end surface that exceeds the outer ring again.

Improve, described vibration damping stuffing box bearing also includes retainer again, and described retainer can place between outer ring and the inner ring actively, and described rolling physical efficiency rollably places retainer.

Improve, described rolling element is ball again.

Improve, described rolling element is needle roller again.

Compared with prior art, lid is equipped with the rubber ring that can play damping effect between the outer ring of vibration damping stuffing box bearing one end face of the present utility model and the inner ring, thereby raising effectiveness in vibration suppression, and rubber ring can also prevent effectively that dust from falling into bearing cavity, not only play dustproof effect, and can also play the effect of sealing; Also have, leave the space between the inner peripheral surface of the outer circumferential face of rubber ring and outer ring platform level circle, avoid producing surface friction drag because rubber ring contacts with bearing outer ring, thereby keep rotation flexibility and the sensitivity of bearing.Therefore the utility model is a kind of ingenious, simple and practical good product that designs.

Embodiment

Below in conjunction with embodiment the utility model is described in further detail.

To Figure 8 shows that vibration damping stuffing box bearing of the present utility model, include outer ring 1, inner ring 2 and rolling element 3 such as Fig. 1, described rolling element 3 can be ball or needle roller, and the rolling element 3 in the present embodiment is elected ball as.Described ball rollably places between outer ring 1 and the inner ring 2, and lid is equipped with rubber ring 4 between the outer ring 1 of described vibration damping stuffing box bearing one end face and the inner ring 2.Described rubber ring 4 is mold pressing or bonding into a single integrated structure with inner ring 2.Outer ring 1 end face of described vibration damping stuffing box bearing is provided with the platform level circle 11 of annular, and described rubber ring 4 outer borders are held in the platform level circle 11 of outer ring 1, and leave space 5 between the inner peripheral surface of the outer circumferential face of rubber ring 4 and platform level circle 11.Described vibration damping stuffing box bearing also can be provided with retainer, and described retainer places between outer ring 1 and the inner ring 2 actively, and rolling element 3 can rollably place retainer, and described rolling element 3 is ball.The upper-end surface of described rubber ring 4 exceeds the upper-end surface of outer ring.The upper-end surface of certain described rubber ring 4 is mutually concordant with the upper-end surface of outer ring, specifically can decide by designing requirement.

The utility model has not only played the effect of dust sealing by at bearing face rubber ring being set, and good damping result, has effectively prolonged the working life of bearing.
