Abstract
The utility model discloses a vibration damping device of a bearing. The vibration damping device of the bearing contains an installing part of the bearing and a base, wherein the installing part of the bearing contains a bearing cavity used for containing one bearing, and an installing hole used for fixedly installing the vibration damping device of the bearing is arranged in the base. The joint of the installing part of the bearing and the base is provided with a slow release groove, and the slow release groove is symmetrically arranged at both sides of the bearing cavity. According to the vibration damping device of the bearing, which is disclosed by the utility model, the installing part of the bearing and the base, which are made of rubber, are utilized. Meanwhile, the joint of the installing part of the bearing and the base is provided with the slow release groove, so that harmful vibration conducted onto the bearing by a power source can be effectively lowered, and the service life of the bearing is greatly enhanced. The replacement is convenient; and moreover, the maintenance cost is low.
Description
Technical field
The utility model relates to a kind of mechanical shock absorption means, or rather, is a kind of bearing damping device.
Background technique
Bearing (bearing) is in mechanical transmission course, to work the parts of fixing and reducing the load friction factor.Also we can say, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor and retainer shaft central position in the power transmission process.Present bearing generally all is directly to be fixed in the bearing bore of machinery, and this means of fixation tends to say that the nuisance vibration of power source directly passes on the bearing, even can cause the fracture of bearing.
China utility model patent ZL200820107201.1 discloses a kind of power transmitting deice; Comprise the cutter shaft, bearing and bearing damper mechanism, driving pawl and the rotary head that are installed in the tool rest; Said cutter shaft wears bearing and bearing damper mechanism and links to each other with said driving pawl, and driving pawl links to each other with transferring power with said rotary head; Said bearing damper mechanism comprises the metal (upper cover, and said metal (upper cover is set in the said bearing outside; Bearing housing is the flexible glue material; Bearing is a ball bearing, and sphere can 360 degree rotations.Still adopted the axle sleeve damping in this dynamic transfer system, in a single day this damping modes is damaged, and changes very inconvenience.
The model utility content
The utility model mainly is to solve the existing in prior technology technical problem, thereby a kind of change convenient and the cheap bearing damping device of maintenance cost are provided.
The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of bearing damping device; Described bearing damping device comprises a Bearing Installation portion and a base; Described Bearing Installation portion comprise one be used to hold a bearing bearing bore, described base is provided with and is used for fixing the mounting hole that described bearing damping device is installed.
As the preferred embodiment of the utility model, the joint of described Bearing Installation portion and described base is provided with a slowly-releasing groove, and described slowly-releasing groove is symmetricly set on the both sides of described bearing bore.
As the preferred embodiment of the utility model, described slowly-releasing groove is sharp narrow groove, the direction of extension of described slowly-releasing groove and the parallel to an axis of described mounting hole down on.
As the preferred embodiment of the utility model, the height of described slowly-releasing groove is less than 1/2nd of the radius of described bearing bore.
Because Bearing Installation portion and base that the bearing damping device of the utility model utilizes rubber to process; Simultaneously be provided with the slowly-releasing groove in the joint of Bearing Installation portion and base; Can effectively reduce power source and conduct to the nuisance vibration on the bearing; Improved the working life of bearing greatly, replacing is convenient and maintenance cost is cheap.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 2 is the STRUCTURE DECOMPOSITION schematic representation of the bearing damping device among Fig. 1;
Fig. 3 is the structural representation of the Bearing Installation portion of the bearing damping device among Fig. 2, and be another visual angle this moment;
Fig. 4 is that Bearing Installation portion among Fig. 3 is along the sectional view of A-A line.
Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
The utility model provides a kind of change convenient and the cheap bearing damping device of maintenance cost.
Extremely shown in Figure 4 like Fig. 1; A kind of bearing damping device 1; This bearing damping device 1 comprises a Bearing Installation portion 11 and a base 12, this Bearing Installation portion 11 comprise one be used to hold a bearing 2 bearing bore 10, this base 12 is provided with and is used for fixing the mounting hole 121 that this bearing damping device 1 is installed.
The joint of this Bearing Installation portion 11 and this base 12 is provided with a slowly-releasing groove 13, and this slowly-releasing groove 13 is symmetricly set on the both sides of this bearing bore 10.
This slowly-releasing groove 13 is a sharp narrow groove down on, the parallel to an axis of the direction of extension of this slowly-releasing groove 13 and this mounting hole 121.
The height H of this slowly-releasing groove 13 is less than 1/2nd of the radius R of this bearing bore 10.
Bearing Installation portion and base that the bearing damping device of this model utility utilizes rubber to process; Simultaneously be provided with the slowly-releasing groove in the joint of Bearing Installation portion and base; Can effectively reduce power source and conduct to the nuisance vibration on the bearing, improve the working life of bearing greatly.
The mentality of designing of the utility model below only is described with a mode of execution, and under the situation that system allows, the utility model can expand to external more function module simultaneously, thereby expands its function to greatest extent.
The above is merely the embodiment of the utility model, but the protection domain of the utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection domain of the utility model.Therefore, the protection domain of the utility model should be as the criterion with the protection domain that claims were limited.
