Abstract
The utility model discloses a vacuum pump with shock -absorbing function in the vacuum pump technical field, include the pump body, install in the base of pump body bottom, still include and install the damper on the base, damper includes the fixed orifices, installs the shock pad in the fixed orifices, the shock pad is made by the elastic rubber, the fixed orifices arranges at the both ends of base, and be equipped with the breach on the fixed orifices, be equipped with on the surface of shock pad with the recess of the structure looks adaptation of fixed orifices, when the shock pad is installed in the fixed orifices, the recess can be crowded the breach and closely blocked and join in marriage in the fixed orifices. Make damper possess good stability and reliability.
Description
Technical field
The utility model relates to vacuum pump technology field, especially a kind of vacuum pump with shock-absorbing function.
Background technique
Vacuum pump operationally, rotor in pump inevitably produces vibrations in rotation process, noise is very large, vibrating noise and motor noise produce the amplification of acoustics due to sympathetic response effect simultaneously, noise when making machine run clearly, very serious to the infringement of machinery, thus have impact on working efficiency and the working life of machine.
At present, the existing damping device for the pump housing comprises the base being fixed on pump housing bottom and the beam being placed in base lower end, the upper end of beam is provided with the projection of cone column, the small end of this projection upward, protruding closely allocating into is located in the closed circular fixation hole of perimeter, support the pump housing of base and base upper end, serve certain damping effect.
The shortcoming of prior art is: because the projection on beam is after allocating fixed hole into, only forms unidirectional position in the axial direction and limits, and in huge vibrations, the projection of cone column is easy to depart from base, reduces the shake-proof ability of device.
Model utility content
The purpose of this utility model is to provide a kind of vacuum pump with shock-absorbing function, makes damper mechanism possess good Stability and dependability.
The purpose of this utility model is achieved in that a kind of vacuum pump with shock-absorbing function, comprise the pump housing, be installed on base bottom the pump housing, also comprise the damper mechanism be arranged on base, described damper mechanism comprises fixed hole, the beam be arranged in fixed hole, described beam is made up of elastic caoutchouc, described fixed hole is arranged in the two ends of base, and described fixed hole is provided with breach; The outer surface of described beam is provided with the groove suitable with the structure of fixed hole, and when beam is arranged in fixed hole, described groove can push through breach and closely card fits in fixed hole.
The utility model when mounted, is located at groove on beam first by breach, then allocates into exactly in fixed hole, and the effect of breach is convenient location, and because groove and fixed hole can form close-fitting, guarantee beam can not depart from base in vibrations.
Compared with prior art, the beneficial effect that the utility model produces is: Stability and dependability obtains very large lifting, ensures that beam can not depart from base when shaking by the groove of beam and the close-fitting of fixed hole; Breach be arranged so that installation efficiency promotes greatly, groove during installation on beam first clamp-ons breach, then allocates in fixed hole exactly, not easily be partial to, guidance quality is fine, as long as pressing beam makes groove and fixed hole form close-fitting can complete installation, very convenient.
As preferred version of the present utility model, described beam is rotary structure, and the coaxial metal lining embedding cylindrical shape in described beam, described metal lining runs through whole beam, and contour with described beam.Beam adds the structural strength that metal lining can promote beam, improves the anti-seismic performance of beam further.
As further preferred version of the present utility model, the opening size of described breach is greater than the external diameter of metal lining, and is less than the external diameter of groove bottom land.There is certain magnitude of interference when getting into breach in groove, will obtain certain installation tightness, strengthens the installation fastness of beam and fixed hole.
Accompanying drawing explanation
Fig. 1 is schematic layout pattern of the present utility model.
Fig. 2 is the scheme of installation of beam in Fig. 1.
Fig. 3 is the sectional view of beam in Fig. 1.
In figure, 1 pump housing, 2 bases, 3 fixed holes, 301 breach, 4 beams, 5 grooves, 6 metal linings.
Embodiment
As Figure 1-3, a kind of vacuum pump with shock-absorbing function, comprise the pump housing 1, be installed on base 2 bottom the pump housing 1, also comprise the damper mechanism be arranged on base 2, damper mechanism comprises fixed hole 3, the beam 4 be arranged in fixed hole 3, beam 4 is made up of elastic caoutchouc, and fixed hole 3 is arranged in the two ends of base 2, and fixed hole 3 is provided with breach 301; The outer surface of beam 4 is provided with the groove 5 suitable with the structure of fixed hole 3, and when beam 4 is arranged in fixed hole 3, groove 5 can push through breach 301 and closely card fits in fixed hole 3.
During installation, be located at groove 5 on beam 4 first by breach 301, then allocate into exactly in fixed hole 3, the effect of breach 301 is convenient location, because groove 5 and fixed hole 3 can form close-fitting, ensures that beam 4 can not depart from base 2 in vibrations.
Above-mentioned beam 4 is rotary structure, and the coaxial metal lining 6 embedding cylindrical shape in beam 4, metal lining 6 runs through whole beam 4, and contour with beam 4.Beam 4 adds the structural strength that metal lining 6 can promote beam 4, improves the anti-seismic performance of beam 4 further.
The opening size of above-mentioned breach 301 is greater than the external diameter of metal lining 6, and is less than the external diameter of groove 5 bottom land.There is certain magnitude of interference when getting into breach 301 in groove 5, will obtain certain installation tightness, strengthens the installation fastness of beam 4 and fixed hole 3.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all any amendment, on an equal basis replacement and improvement etc. done within spirit of the present utility model and principle, all should drop within protection domain of the present utility model.
