Definitions

  • the present invention relates to a rubber support member for a compressor that elastically supports a compressor body that generates vibration on a base, and a compressor provided with this support member.
  • FIG. 5 shows a main part of the invention described in Patent Document 1.
  • the compressor support device shown in FIG. 5 includes a mounting leg 2 provided around the lower portion of the compressor 1, a plurality of bolts 4 erected on the base 3 facing the mounting leg 2, and an upper portion. It includes a plurality of supports 5 that are attached to the mounting legs 2 and that elastically support the compressor 1 through the bolts 4, and a nut 6 that is attached to the upper part of the bolts 4.
  • the support 5 is a rubber-based elastic body, and is provided with an annular holding portion 5a that holds the periphery of the mounting hole 2a of the mounting leg 2 on the upper outer circumference.
  • the lower part of the support 5 is a body portion 5b that elastically supports between the mounting legs 2 and the base 3.
  • a plurality of radial fan-shaped convex portions 5e are formed on the bottom surface portion 5d of the support body 5.
  • the amplitude of vibration during normal operation is small, and the amount of deformation of the support rubber for the compressor is also relatively small.
  • a large vibration with a large amplitude may be applied to the support rubber for the compressor due to a large vertical movement or a drop impact, and the amount of deformation of the support rubber for the compressor is also relatively large. Therefore, the support rubber for the compressor is required to have a vibration damping function by the vibration generating portion and a displacement suppressing function due to vibration or impact during transportation.
  • the support rubber is made less rigid, vibrations with relatively small amplitudes during normal operation can be effectively damped, but it becomes difficult to handle vibrations and shocks with relatively large amplitudes that occur during transportation and installation, and the compressor becomes difficult. It will be greatly displaced. As a result, a large amount of stress is generated in the piping connected to the compressor, which causes cracks and breakage in the piping, which may reduce reliability. On the contrary, if the support rubber is made highly rigid, the vibration and impact during transportation and installation are effectively suppressed and the displacement of the compressor is suppressed, but the vibration cannot be effectively damped during normal operation.
  • An object of the present invention is to be able to attenuate vibrations having a relatively small amplitude (vibrations during normal operation) and to suppress displacement of the compressor due to vibrations having a relatively large amplitude (for example, vibrations or shocks during transportation or installation). It is an object of the present invention to provide a support member for a compressor capable of the present invention and a compressor including the support member.
  • the compressor according to the present invention includes a compressor main body and a rubber support member that elastically supports the compressor main body on a base.
