Detailed description of the invention
By further illustrating the technological means and effect that this utility model taked by reaching predetermined utility model purpose, below in conjunction with accompanying drawing and preferred embodiment, to the foundation detailed description of the invention of this utility model application, structure, feature and effect thereof, after describing in detail such as.In the following description, what different " embodiments " or " embodiment " referred to is not necessarily same embodiment.Additionally, special characteristic, structure or feature in one or more embodiment can be combined by any suitable form.
As shown in figures 1 and 3, embodiment of the present utility model provides a kind of damping frame, including damping means 2 and rack body 1, described rack body 1 is provided with bracket fixture portions 13, and described bracket fixture portions is for being connected with parts to be installed.Being further opened with on described bracket fixture portions 13 installing groove 11, described damping means 2 has elasticity, and is detachably inserted in described installation groove 11, and the thickness of described damping means is more than the degree of depth of described installation groove.When on described damping frame is fixed on to be installed by described bracket fixture portions 13, described rack body 1 is fixedly supported on the parts to be installed such as installed surface of installing plate through described damping means 2, and described rack body 1 not installed surface with parts to be installed directly contacts.Now, contact with to be installed of installing plate is not metal rack, but has the damping means 2 of damping effect.When damping frame and installing plate are fixed, damping means 2 isolation mount body 1 and installing plate, make both not contact, isolation is transmitted in the vibration loading to motor, good damping effect can be played so that running noise of motor is little, service life is long.Damping means 2 is constant with the contact area of installing plate simultaneously.
In order to be fixed on to be installed by rack body 1, described bracket fixture portions 13 includes being arranged on the screwed hole installed in groove 11.
As it is shown on figure 3, in order to be fixed between to be installed and described rack body 1 by damping means 2, on described damping means, corresponding position is provided with through hole 21.In one embodiment, described through hole 21 diameter is more than described screwed hole diameter, consequently facilitating after described damping means 2 embeds in described installation groove 11, fixing screw can screw in described screwed hole through described through hole 21.
Preferably, described rack body 1 being provided with support installation foot 14, described bracket fixture portions is arranged on described support installation foot 14.
In order to reach preferable effectiveness in vibration suppression, described damping means 2 is cushion rubber, it is preferred to use elastomeric material is processed.Its hardness should be set to suitable stiffness, it is impossible to too soft, otherwise can deform when extruding is fixing, cause effectiveness in vibration suppression to lose efficacy.
In an embodiment of the present utility model, described installation groove 11 is U-shaped groove, and described cushion rubber is U-shaped cushion rubber.The thickness of U-shaped cushion rubber is higher than the degree of depth of U-shaped groove, and the length of U-shaped groove is not more than the length of support installation foot 14, and the width of U-shaped groove is less than the width of support installation foot 14.Preferably, the length of U-shaped cushion rubber is consistent with the length of U-shaped groove, the width ratio U-shaped recess width wide 1～2mm of U-shaped cushion rubber.
Owing to being constantly be generated vibration in motor operation course, accordingly, there exist the possibility that described damping means 2 deviates from described installation groove 11, thus cause effectiveness in vibration suppression to decline and even disappear.Therefore, as with the embodiments shown in figures 2 and 3 in, one end of described U-shaped groove is provided with straight trough, is used for preventing described damping means 2 from moving relative to described U-shaped groove.
The straight trough 12 arranged in one end of described U-shaped groove, the width of the width ratio U-shaped groove of straight trough 12 is big, and also has one at the length direction of straight trough 12 and determine width.The screwed hole of certain depth is had, for installing fixing with installing plate in the centre of U-shaped groove.
Correspondingly, it is provided with the boss 22 corresponding with described straight trough 12 (the most as shown in Figure 3 in one end of described U-shaped cushion rubber, boss 22 is at the width of described U-shaped cushion rubber, protruding along planar ends), straight trough 12 size that the length dimension of boss 22 is slightly less than on U-shaped groove, consequently facilitating cushion rubber is installed on support installation foot 14.The through hole more bigger than the screwed hole in U-shaped groove is had, it is simple to screw is installed at the center of described U-shaped cushion rubber.When U-shaped cushion rubber is arranged on the U-shaped groove of rack body, owing to the width dimensions of cushion rubber is more bigger than the width of U-shaped groove, in cushion rubber rack body to be put into, then need to make cushion rubber deform, and rubber belongs to flexible material, after cushion rubber clamp-ons rack body, due to elastic effect cushion rubber meeting swelling rack body, therefore cushion rubber and rack body interference fit, cushion rubber is difficult to come off from rack body.
When support is installed with installing plate, owing to cushion rubber exceeds support U-shaped groove part, so contact with installing plate is cushion rubber, owing to the boss of cushion rubber is less than the straight trough on the U-shaped groove of rack body, so cushion rubber is when being extruded, having unnecessary space on U-shaped groove allows cushion rubber move when deforming, and is unlikely and cushion rubber is damaged by pressure.
Embodiment of the present utility model provides a kind of motor, and described motor includes above-mentioned damping frame.Especially, in a preferred embodiment of the present utility model, this motor is external rotor electric machine.One skilled in the art will appreciate that this damping frame does not limit to and be applied to external rotor electric machine.
To sum up, the damping frame that this utility model embodiment provides, under identical mounting condition, improve the way of contact of support and installing plate, solve vibration problem of transmission, motor noise is improved, and improves the service life of motor.
Skilled addressee readily understands that, on the premise of not conflicting, above-mentioned each advantageous manner can freely combine, superposition.
The above, it it is only preferred embodiment of the present utility model, not this utility model is made any pro forma restriction, any simple modification, equivalent variations and the modification made above example according to technical spirit of the present utility model, all still falls within the range of technical solutions of the utility model.
