Problems solved by technology

The noise sound wave from the compressor hits the wall of the corner plate of the base and is reflected back, intersects with the noise sound wave from the compressor to generate interference and form a more complex sound field, which increases the noise.
[0005] In addition, after the compressor is welded to the base, it is easy to have different distances from the outer edge of the compressor shell to the small holes for fixed connection on the three lugs of the base. There are large and small differences, and the same distance cannot be guaranteed.
At different distances, the echo time reflected from the noise emitted by the compressor is different, and they cross together, which increases the noise

Abstract

The invention discloses a sealed rotary compressor base seat, wherein the compressor contains the following parts: sealed case, motor with rotor and stator; rotary axle plugs into the axle hole of rotor center with eccentric part under the rotary axle; piston outsides; compressor mechanic part with cylinder body, upper bearing and lower bearing forming compressing part; sealed case base connects on the base seat with queen opening section with two plane layers that displays triangle shape, which forms free field and spring structure to reduce shock and noise.

Description

technical field [0001] The invention belongs to a sealed rotary compressor base, in particular to a sealed rotary compressor base capable of reducing noise and vibration. Background technique [0002] At present, the structure of the hermetic rotary compressor is as follows: figure 1 As shown, it includes a sealed housing 1, a motor 4 composed of a rotor 2 and a stator 3; a rotating shaft 5 is inserted into the shaft hole 2a in the center of the rotor, and the lower end of the rotating shaft has an eccentric portion 6 and a piston 7 on the outside thereof. A compression space 8 is formed, and a compression mechanical part 12 composed of a cylinder body 9 and upper and lower bearings 10 and 11 is installed; the bottom of the sealed casing is connected to the base 13 . [0003] Prior art bases such as figure 2 , image 3 As shown, the base is provided with three arc-shaped lugs 14, the middle of which is recessed, and is approximately triangular disc-shaped body. There is...
