The silencing cover 200 is a metal piece and can be clamped on the conical surface 111 of the bearing through interference fit, and the inner surface of the silencing cover 200 can be more smoothly contacted with the bearing due to the arrangement of the concave part 210. In this embodiment, the concave portion 210 is in interference fit with the tapered surface 111 of the flange portion 110, the opening of the sound attenuation cover 200 is expanded by the interaction between the sound attenuation cover 200 and the bearing, and the concave portion 210 is tightly attached to the tapered surface 111 by the elastic force generated by deformation after the sound attenuation cover 200 is expanded. The radius of the conical surface 111 of the flange 110 is gradually reduced from top to bottom, and when the silencing cover 200 is assembled with the bearing, the open end of the silencing cover 200 is close to the bearing and surrounds the bearing until the silencing cover 200 generates a certain elastic force to tightly attach to the conical surface 111.

In this embodiment, the edge of the sound-deadening cap 200 is provided with the extending portion 220, and the extending portion 220 extends in the direction away from the central axis of the sound-deadening cap 200, so that the opening end of the sound-deadening cap 200 extends outwards, and the assembly outside the bearing is facilitated.

In this embodiment, the bearing further includes a receiving portion 120, a groove 121 is disposed on an end surface of the receiving portion 120, the sound attenuation cover 200 is provided with a protrusion 240, and the protrusion 240 is snapped into the groove 121, so that the sound attenuation cover 200 and the bearing can be more stably connected. In this embodiment, the angle between the tapered surface 111 and the vertical direction is 1 ° to 10 °, and the inclination angle of the tapered surface 111 is limited to this range to be more stable and to be in closer contact with the sound-deadening cap 200.

After the bearing enters the predetermined position in the silencing cover 200, the silencing cover 200 can be pressed outside the bearing by a compressor shell or a fastener, and the two are kept in contact fit.

The utility model also discloses a compressor, it includes the seal structure of foretell compressor amortization lid 200 and bearing.

The utility model discloses a compressor amortization lid 200 is more convenient when making amortization lid 200 and the sealed equipment of bearing with the seal structure of bearing, and the bearing enters into to amortization lid 200 more easily to amortization lid 200 can be with the stable sealed laminating of conical surface 111 of bearing. In this embodiment, the bearing is a lower bearing in the compressor, and in other embodiments, the bearing may also be an upper bearing of the compressor.

Example two

Referring to fig. 4, in the present embodiment, the sound-deadening cap 200 has a bending portion 230, and the bending portion 230 is disposed on a side of the concave portion 210 away from the edge of the sound-deadening cap 200. Such an arrangement can make the elastic force generated when the opening of the noise-reduction cover 200 is deformed more stable.

The embodiment also discloses a compressor, which comprises the sealing structure of the compressor silencing cover and the bearing.
