Noise control is the important topic that environmental conservation is faced, such as motor, and noise and vibration are referring mainly to of motor
Mark one of, reflect design of electrical motor quality, technological level and mounting technique level, bearing be the necessary part of most motors it
One, bearing in operation process because a variety of causes unavoidably produces vibration, thus causing noise, in order to improve China's motor
Product in the competitiveness of international market, in the urgent need to take necessary controlling measurement or reduce the vibration being produced by bearing operation and
Noise, thus effectively reduce the overall vibration of motor and noise.
As a kind of reduction motor oscillating of Patent No. CN 205178721 U and the bearing chamber structure of noise, including motor
End cap, is provided with annular protrusion in the middle of described electric motor end cap, described annular protrusion surrounds bearing chamber, described annular protrusion
Inwall is provided with several equidistant annular grooves, and described annular groove embeds and is cased with damping ring, and described damping ring is a part of
It is in annular protrusion, it is indoor that a part is in bearing.This utility model provides a kind of axle reducing motor oscillating and noise
Hold cell structure, due to being additionally arranged damping ring, can effectively reduce the vibration producing because of bearing operation and therefore produce
Noise, thus improve the overall performance of equipment.Although this patent solves the problems referred to above, in place of there is also some shortcomings,
It is known that annular groove is dug on end cap medial wall, more trouble and difficulty, also can increase production cost simultaneously, and due to
Damping ring negligible amounts, after some time it is possible to reach effectiveness in vibration suppression undesirable, but by increase damping ring by way of solve this problem
Words, can return to a difficult problem again, that is, dig annular groove on end cap medial wall, more trouble and difficulty, also can simultaneously
Increase a difficult problem for production cost, and under bearing runs up, the damping ring being enclosed within bearing may get rid of in groove
De-.
Content of the invention
The purpose of this utility model is exactly in order to solve an above-mentioned difficult problem and to provide a kind of bearing chamber structure of motor.
Technical problem of the present utility model is mainly addressed by following technical proposals：
A kind of bearing chamber structure of motor, including bearing chamber body, described bearing chamber body medial wall is circumferentially with many
The groove that group is vertically arranged, and it is located on the medial wall at bearing chamber body top end opening an also circle groove, described groove divides
Do not connect with groove and bearing chamber body interior space, wherein trench cross section is in isosceles trapezoid, and bottom and bearing chamber basis thereon
Body inner space connects, and is equipped with matched shock absorption bar, and the upper bottom of shock absorption bar extends to bearing in described groove
In the body interior space of room, the upper bottom of wherein shock absorption bar is additionally provided with arc notch, is provided with damping ring in described groove, and vibration damping
It is fixedly connected between ring and shock absorption bar, the medial wall of wherein bearing chamber body is provided with the arc connecting two adjacent shock absorption bars
Stiffener, is integrated setting between described shock absorption bar, damping ring and stiffener three.
Preferably, it is in same level between described damping ring top and bearing chamber body top.
Preferably, two waist edge side walls of described shock absorption bar are uniformly provided with agnail.
Preferably, between the inner arc side of described stiffener and arc notch constitute a circle, and this circular diameter with
The internal diameter of damping ring is equal.
The beneficial effects of the utility model are：This utility model is due to being additionally arranged the pass of shock absorption bar, damping ring and stiffener
System, can effectively reduce the vibration producing because of bearing operation and the noise therefore producing, thus improve the whole of equipment
Body performance, and because trench cross section is in the relation of isosceles trapezoid, improve steadiness in groove for the shock absorption bar, simultaneously also logical
Cross stiffener and lift the steadiness between shock absorption bar further.

Specific embodiment
Below by embodiment, and combine accompanying drawing 1-2, the technical solution of the utility model is made more specifically
Bright.
A kind of bearing chamber structure of motor, including bearing chamber body 1, described bearing chamber body 1 medial wall is circumferentially with
Multigroup groove 2 being vertically arranged, and it is located on the medial wall at bearing chamber body 1 top end opening an also circle groove 3, described recessed
Groove 3 is connected with groove 2 and bearing chamber body 1 inner space respectively, wherein groove 2 section be in isosceles trapezoid, and thereon bottom with
Bearing chamber body 1 inner space connects, and is equipped with matched shock absorption bar 4 in described groove 2, and the upper bottom of shock absorption bar 4
End extends in bearing chamber body 1 inner space, and the upper bottom of wherein shock absorption bar 4 is additionally provided with arc notch 6, in described groove 3
It is provided with damping ring 5, and is fixedly connected between damping ring 5 and shock absorption bar 4, the medial wall of wherein bearing chamber body 1 is provided with connection
The arc stiffener 7 of two adjacent shock absorption bars 4, is integrated between described shock absorption bar 4, damping ring 5 and stiffener 7 three and sets
