Abstract
The utility model discloses a motor damping strip. The motor damping strip is composed of an upper metal material layer, a middle elastic material layer and a lower metal material layer. Each of two side ends of the upper metal material layer is provided with a vertical motor base installing hole, each of two side ends of the lower metal material layer is provided with a vertical fixing base installing hole, and an upper surface and a lower surface of the middle elastic material layer is respectively and closely connected with a lower surface of the upper metal material layer and an upper surface of the lower metal material layer. According to the utility model, the motor damping strip is divided into three parts, the upper and lower layers are metal material layers, and the middle layer is the elastic material layer having a damping function; and, when installation is carried out, motor feet are directly fixed on the upper metal material layer, and then a fixing base is connected with the lower metal material layer of the damping strip, so that a rigid connection between a motor and the fixing base is changed into a flexible connection, vibrations and noises generated during running of the system can be effectively reduced, filtered and absorbed, the service life of the whole motor system is improved, and the influence of noises on surrounding environment is reduced.
Description
Technical field
The utility model relates to motor damper element field, is specifically related to a kind of motor damping bar.
Background technology
Employing motors such as present domestic hydraulic power unit, hydraulic system, hydraulic machinery and engineering machinery are rigidly connected as generally using in the product of power output, not have technology to guarantee definitely coaxial because motor and pump are current when mounted, zero error, so can produce noise and vibrations during system works, noise can exert an influence to the environment of periphery, the vibrations meeting exerts an influence to service life of a machine, the bearing, oil sealing, connector etc. that comprise motor and pump damage too early, so just reduce production efficiency, improved cost.The solution of motor damping aspect is a simple rubber blanket or the circular Rubber shock-absorbing pad of having added between motor footing and holder in the prior art, these two kinds of schemes all have little effect, because the most basic aspect is motor footing construction bolt and still directly is connected with holder, the vibrations that system produces still can directly be transmitted mutually by connecting bolt, the vibrations and the noise that produce in the time of so just can't effectively reducing and filter the absorption system running, the useful life that also can't improve whole hydraulic system.
The utility model content
For solving the problems of the technologies described above, we have proposed a kind of motor damping bar, motor and holder are converted to by being rigidly connected flexibly connect, and effectively reduce and filter vibrations and noise that absorption system when running produces, the life-span of having improved whole hydraulic system.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of motor damping bar is made up of last metal material layer, middle elastomeric layer and following metal material layer; The described metal material layer two side ends that goes up vertically has the motor base installing hole, and described metal material layer two side ends down vertically has the holder installing hole; The elastomeric layer upper surface closely is connected with described metal material layer upper surface down with the described metal material layer lower surface of going up respectively with lower surface in the middle of described.
Preferably, described middle elastomeric layer is natural rubber or the moulding of acrylonitrile-butadiene rubber material.
Preferably, described upward metal material layer and described metal material layer down are No. 45 steel material moulding.
Preferably, the described metal material layer of going up also vertically offers screw near described motor base installing hole inboard.
Preferably, on the described middle elastomeric layer below the described screw, also have connecting hole.
Pass through technique scheme, motor damping bar of the present utility model is divided into 3 parts, two-layer up and down is metal material layer, the centre is the elastic material layer with cushioning effect, the motor footing directly is fixed on the metal material layer during installation, holder is connected with the following metal material layer of damping bar then, motor and holder just convert to by being rigidly connected and flexibly connect like this, the vibrations and the noise that produce in the time of just can effectively reducing and filter the absorption system running, improve the useful life of whole electric system, also reduced the influence that noise produces surrounding enviroment.

Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model provides a kind of motor damping bar, motor and holder is converted to by being rigidly connected flexibly connect, and effectively reduces and filter vibrations and noise that absorption system when running produces, the life-span of having improved whole hydraulic system.
Below in conjunction with embodiment and embodiment the utility model is described in further detail.
Embodiment.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of motor damping bar is made up of last metal material layer 1, middle elastomeric layer 2 and following metal material layer 3; Described metal material layer 1 two side ends that goes up vertically has motor base installing hole 4, and described metal material layer 3 two side ends down vertically have holder installing hole 5; Elastomeric layer 2 upper surfaces closely are connected with described metal material layer 3 upper surfaces down with described metal material layer 1 lower surface of going up respectively with lower surface in the middle of described.
Wherein, described middle elastomeric layer 2 is the moulding of natural rubber material, also can adopt the moulding of acrylonitrile-butadiene rubber material, will not do restriction at this, and these equally all belong to protection range of the present utility model; Described upward metal material layer 1 and described metal material layer 3 down are No. 45 steel material moulding; The described metal material layer 1 of going up also vertically offers screw 6 near described motor base installing hole 4 inboards; On the described middle elastomeric layer 2 below the described screw 6, also have connecting hole 7, adopt bolt will go up metal material layer 1 at this and strengthen being connected with middle elastomeric layer 2, so that its more firm connection.
Pass through technique scheme, motor damping bar of the present utility model is divided into three parts, two-layer up and down is metal material layer, the centre is the elastic material layer with cushioning effect, the motor footing directly is fixed on the metal material layer during installation, holder is connected with the following metal material layer of damping bar then, motor and holder just convert to by being rigidly connected and flexibly connect like this, the vibrations and the noise that produce in the time of just can effectively reducing and filter the absorption system running, to shake minimizing and filter 23 more than 0%, noise can reduce 6-10dBA, has improved the life-span of whole electric system, has reduced the influence that noise produces surrounding enviroment.
Above-described only is a kind of motor damping bar preferred implementation of the present utility model; should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
