Impact idler, it includes roll body, on described roll body outer wall casting be cased with rubber, along the circumferential direction opened on described rubber
There are multiple spaced grooves each other.The effect of absorbing sound and lowering noise is played by groove, but is found through experiment, it drops
The rate of making an uproar remains within reduced levels, especially when conveying some intensive block material (such as coal cinders), noise it is still without cease in
Ear.
Utility model content
The purpose of this utility model is to provide a kind of Jing Yin buffer-type carrying roller, by the way that sound-absorbing groove is arranged into shaped face knot
Structure, preferably solves noise problem.
What the purpose of this utility model was realized in：A kind of Jing Yin buffer-type carrying roller, including roll body, it is characterised in that：
Integrated injection molding has a rubber ring on the roll body outer circumference surface, and rubber ring surface distributed has a sound-absorbing groove of annular, and sound-absorbing groove is along roll body
Axially spaced-apart is distributed, and the attraction groove is the symmetrical structure being connected to form that interlocked by some arc convex and arc-shaped recess.
By using above-mentioned technical proposal so that sound-absorbing rooved face is uneven, adds Air mycetes herein,
With air particle because energy loss caused by vibrations friction is just bigger when sound wave is transferred to herein, therefore serve noise reduction just
Become apparent from；Meanwhile by rubber ring integrated injection molding on roll body, then the Mechanical Builds processing to this special-shaped sound-absorbing groove is got up just more
Add conveniently, directly can be produced by being molded.
Preferably, the arc-shaped recess includes central concave and side is recessed, and central concave is in the middle part of attraction groove, side
Depression is symmetricly set on central concave both sides and connects the arc convex between the two, and side recessed top extends to rubber
Cushion rubber surface.
Preferably, the side depression arc radius is more than central concave arc radius.
By using above-mentioned technical proposal, sound-absorbing effect is good, and during carrying roller own rotation, noise caused by sound-absorbing groove itself
Relatively low, the larger side depression of radius preferably maintains the elastic reset ability of sound-absorbing groove, and has impurities removal ability concurrently.
Preferably, the side depression is provided with sound-absorption hole, and sound-absorption hole relative side depression radially extends inside.
By using above-mentioned technical proposal, noise is preferably reduced, radially extends and ensure that sound-absorption hole does not interfere with arc
Shape raised thickness and elastic force.
Preferably, roll body both ends inner ring is fixed with bearing, and bearing outside is provided with the inner seal ring mutually fastened and outside
The labyrinth seal that sealing ring is formed, closure is covered with exterior seal ring.
Preferably, the closure inner ring is provided with axle sleeve, and the closure has the first sealing lip towards axle sleeve extension
With the second sealing lip extended towards exterior seal ring end face, the first sealing lip and the second sealing lip form Figure of eight structure.
By using above-mentioned technical proposal, the structure of sealing lip on labyrinth seal and closure can preferably play close
Envelope acts on, and avoiding particulate matter from entering bearing influences carrying roller rotation.

Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-2：
A kind of Jing Yin buffer-type carrying roller, including roll body 1, it is characterised in that：There is integrated injection molding on the outer circumference surface of roll body 1
Rubber ring 2, the surface distributed of rubber ring 2 have the sound-absorbing groove 3 of annular, and sound-absorbing groove 3 is distributed along the axially spaced-apart of roll body 1, the attraction groove
It is the symmetrical structure being connected to form that interlocked by some arc convex 3c and arc-shaped recess 3a, 3b.It is arranged such so that sound-absorbing groove 3
Surface irregularity, Air mycetes herein are added, with air particle because of vibrations friction production when sound wave is transferred to herein
Raw energy loss is just bigger, therefore serves noise reduction and just become apparent from；Meanwhile by the integrated injection molding of rubber ring 2 in roll body 1
On, then the Mechanical Builds processing to this special-shaped sound-absorbing groove 3 is got up just more convenient, directly can be produced by being molded.
Wherein, the arc-shaped recess includes central concave 3b and side depression 3a, central concave 3b in the middle part of attraction groove,
Side depression 3a is symmetricly set on central concave 3b both sides and connects the arc convex 3c between the two, at the top of the depression 3a of side
Extend to the surface of rubber ring 2.The side depression 3a arc radius is more than central concave 3b arc radius.Sound-absorbing effect
It is good, and during carrying roller own rotation, noise caused by sound-absorbing groove 3 itself is relatively low, the larger side depression 3a of radius is preferably kept
The elastic reset ability of sound-absorbing groove 3, and have impurities removal ability concurrently.
Specific to see Fig. 1 amplification units, the side depression 3a is provided with sound-absorption hole 4, the relative side of sound-absorption hole 4 depression 3a footpaths
To extending inside.It is arranged such, preferably reduces noise, radially extends and ensure that sound-absorption hole 4 does not interfere with arc convex 3c
