Abstract
The utility model relates to an amortization bearing, including inner circle, outer lane, kingpin and holder, interior snare is established in the outer lane, and the holder setting has a plurality of fenestras on the holder between inner circle and outer lane, and the kingpin setting is in the fenestra, and the outer lane is inside to have and fall the structure of making an uproar, falls the structure of making an uproar and includes cavity annular cavity and acoustical panel, and cavity annular chamber position is inside and coaxial with the outer lane in the outer lane, and the acoustical panel setting is internal at the cavity annular chamber, and the acoustical panel is for the cork and in the internal ring -type that is of cavity annular chamber. The utility model discloses having set up and having fallen the structure of making an uproar, the inside noise that sends of partly bearing can be kept apart to cavity annular cavity itself, at the internal acoustical panel that still is equipped with of cavity annular chamber for the noise is absorbed by the acoustical panel, plays the effect of amortization, have the bloop on the inner wall of cavity annular cavity, further make the noise in the internal emergence of cavity annular chamber reflection, the noise that reduces outwards to send size.
Description
Technical field
This utility model relates to a kind of noise reduction needle bearing.
Background technology
The major function of bearing is to support machinery rotary body, reduces the coefficient of friction in its motor process, and ensures its time
Turn precision.Along with the development of technology, user is more and more higher to the prescription of bearing, does not require nothing more than bearing and has high accuracy, length
Life-span, but also require that bearing has the superperformance of low vibration, low noise, the most in recent years, along with super high speed electric work
The development and application of tool, in some matched host machine, it is relatively big that what bearing produced holds noise, creates noise pollution.
Utility model content
The technical problems to be solved in the utility model is: in order to reduce the bearing noise when high-speed rotation, and this practicality is new
Type provides a kind of noise reduction needle bearing.
This utility model solves its technical problem and be the technical scheme is that a kind of noise reduction needle bearing, including inner ring,
Outer ring, needle roller and retainer, described inner ring is set in outer ring, and described retainer is arranged between inner ring and outer ring, retainer
On there is some fenestras, described needle roller is arranged in fenestra, has denoising structure inside described outer ring, and described denoising structure includes
Hollow ring cavity and acoustical panel, it is internal and coaxial with outer ring that described hollow ring cavity is positioned at outer ring, and described acoustical panel is arranged
In described hollow ring cavity, acoustical panel be cork and in hollow ring cavity in the form of a ring.
In order to improve noise reduction, the inwall of described hollow ring cavity offers some bloops, described bloop
For blind hole.
The beneficial effects of the utility model are, noise reduction needle bearing of the present utility model, are provided with denoising structure, hollow ring
Shape cavity itself can isolate the noise that a part of Bearing inner sends, and is additionally provided with acoustical panel in hollow ring cavity so that
Noise is absorbed by acoustical panel, thus prevents noise from sending, and plays the effect of noise reduction；Meanwhile, on the inwall of hollow ring cavity
There is bloop, further such that noise reflects in hollow ring cavity, on the one hand make noise at hollow ring cavity
Inwall on energy loss, on the other hand make noise reflect back, reduce the noise level sent out.
Accompanying drawing explanation
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the cross-sectional view of noise reduction needle bearing of the present utility model.
In figure 1, inner ring, 2, outer ring, 3, needle roller, 4, retainer, 5, hollow ring cavity, 6, acoustical panel, 7, bloop.
Detailed description of the invention
Presently in connection with accompanying drawing, this utility model is described in further detail.These accompanying drawings are the schematic diagram of simplification,
Basic structure of the present utility model is described the most in a schematic way, and therefore it only shows the composition relevant with this utility model.
As it is shown in figure 1, a kind of noise reduction needle bearing of the present utility model, including inner ring 1, outer ring 2, needle roller 3 and retainer
4, described inner ring 1 is set in outer ring 2, and described retainer 4 is arranged between inner ring 1 and outer ring 2, retainer 4 has some
Fenestra, described needle roller 3 is arranged in fenestra, and described outer ring 2 is internal has denoising structure, and described denoising structure includes hollow ring
Cavity 5 and acoustical panel 6, it is internal and coaxial with outer ring 2 that described hollow ring cavity 5 is positioned at outer ring 2, and described acoustical panel 6 is arranged on
In described hollow ring cavity 5, acoustical panel 6 be cork and in hollow ring cavity 5 in the form of a ring.
Offering some bloops 7 on the inwall of described hollow ring cavity 5, described bloop 7 is blind hole.
Noise reduction needle bearing of the present utility model, is provided with denoising structure, and hollow ring cavity 5 itself can isolate one
The noise sent inside two-part bearing, is additionally provided with acoustical panel 6 in hollow ring cavity 5 so that noise is absorbed by acoustical panel 6, from
And prevent noise from sending, play the effect of noise reduction；Meanwhile, the inwall of hollow ring cavity 5 has bloop 7, further
Noise is reflected in hollow ring cavity 5, on the one hand makes noise energy on the inwall of hollow ring cavity 5 damage
Lose, on the other hand make noise reflect back, reduce the noise level sent out.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, related work people
Member can carry out various change and amendment completely in the range of without departing from this utility model technological thought.This reality
The content being not limited in description by novel technical scope, it is necessary to determine its technology according to right
Property scope.
