Abstract
The utility model relates to a balance weight device. The balance weight device comprises a balance weight ring, wherein a plurality of small holes are formed in an axial surface of the balance weight ring, the balance weight ring is fixed to a tool to be balanced by weight through a fixing component. The balance weight device is reasonable in design. The holes are formed in the lateral surface of the balance weight ring, a rotation shaft is balanced by adjusting the relative positions of the holes in the balance weight ring, the problems of the rotation shaft caused by abrasion are effectively resolved, the service life is prolonged, and the balance weight device is convenient to use, and saves time and labor.
Description
Technical field
The utility model relates to Equilibrator, relates in particular to a kind of counter weight device.
Background technique
The running of machinery can't do without having the part apparatus of rotating function, such as motor, emery wheel, engine, transmission shaft, main shaft and steam turbine etc.If these component of making in engineering can reach material and evenly and not have error, these component can reach balanced rotation so; But, all there is error to exist in the processing and assembling of reality, make these component when rotating, produced and departed from mental and physical efforts and make rotating shaft produce some deflection, caused the rotation can't held stationary, will cause vibration like this, produced noise, accelerate the wearing and tearing of bearing, shortened mechanical life greatly, even can damage incidents in the time of serious.
At present, people expect that also adding dynamic poise device in the rotating shaft of machinery carries out counterweight, thereby reduce the wearing and tearing of countershaft, but after using a period of time, the deflection phenomenon may appear again in rotating shaft, so need to again change or adjust counterweight, counterweight is originally pulled down not only wasting time and energy of again more renewing, and cost increase also.
The model utility content
The utility model has overcome the deficiencies in the prior art, and a kind of counter weight device is provided, and this counter weight device can be applicable on dynamic poise device, can effectively solve rotating shaft because of the problem that wearing and tearing produce, and increases the service life.
For achieving the above object, the technical solution adopted in the utility model is:
The utility model provides a kind of counter weight device, it is characterized in that: comprise counterweight ring, the axial plane of described counterweight ring is provided with several apertures, and described counterweight ring is fixed in and treats on weight fixture by fixing-assembly.
In preferred embodiment of the utility model, further comprise, described counterweight ring inwall is provided with fixed hole.
In preferred embodiment of the utility model, further comprise, described aperture is evenly distributed on described counterweight ring axial plane.
In preferred embodiment of the utility model, further comprise, the number of described aperture is even number.
In preferred embodiment of the utility model, further comprise, described fixing-assembly is screw.
In preferred embodiment of the utility model, further comprise, the surface of described counterweight ring is provided with some scales.
The utility model has solved the defect that exists in the background technique, the utility model is reasonable in design, be provided with hole at the counterweight ring side surface, can make rotating shaft reach balance by the relative position of adjusting hole on counterweight ring, not only effectively solve the problem that rotating shaft produces because of wearing and tearing, increase the service life, but also easy to use, time saving and energy saving.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation of preferred embodiment of the present utility model.
Embodiment
In conjunction with the accompanying drawings and embodiments the utility model is described in further detail now, these accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The utility model provides a kind of counter weight device, and it comprises counterweight ring 1, and counterweight ring 1 can be fixed on the frock for the treatment of counterweight, the axial plane of counterweight ring 1 is provided with several apertures 2, aperture 2 is set to even number, and according to different needs, increases number, and aperture 2 is to be evenly distributed on the axial plane of counterweight ring; Counterweight ring 1 is fixedly treated on the frock of counterweight by fixing-assembly.Preferred screw 3 is fixing-assembly in the present embodiment, and also is provided with the fixed hole 4 that is used in conjunction with screw 3 above counterweight ring 1.
Can counterweight ring 1 be fixed on above the frock for the treatment of counterweight with other modes such as connecting pin, rivets in another embodiment.
The rotating shaft counterweight that counterweight ring 1 can be used for being placed on above different machineries is used, can deflect when around rotating shaft, counterweight is unequal, therefore can first fixing-assembly be unclamped, adjust again the relative position of aperture 2 above counterweight ring 1 counterweight ring relative with another, utilize aperture 2 that counterweight ring 1 arranges above to change and turn axial counterweight, rotate held stationary until turn the average and rotating shaft of axial counterweight, the counterweight success is described again, then fixing-assembly 3 is screwed, counterweight ring 1 just is fixed on above the frock for the treatment of counterweight.In addition, the surface of counterweight ring 1 is provided with some scales (not shown), and these scales can clearly be known the cheap degree of rotating shaft conveniently when counterweight is adjusted, more be conducive to the measure of precision of counterweight ring in counterweight.
Above foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related personnel can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on specification, must determine technical scope according to the claim scope.
