Description

Technical Field

[0001] This utility model belongs to the field of compressor vibration damping bushings, specifically, it relates to a gas compressor vibration damping bushing. Background Technology

[0002] The supporting components of a compressor are a significant pathway for the transmission of structural noise and overall vibration. The crank-connecting rod mechanism of a compressor undergoes reciprocating motion. In the direction of piston movement, it is mainly affected by reciprocating inertial force, which is primarily influenced by the rotational speed. However, in the direction perpendicular to piston movement, it is mainly affected by gas force, which is significantly influenced by operating conditions and is therefore largely unknown.

[0003] Patent application CN209262136U discloses a compressor vibration damping bushing. Paragraph 0026 of the specification discloses that: the compressor includes a housing, an iron support and a compression spring are provided on the base of the housing, the vibration damping bushing is fitted onto the iron support through an assembly hole, the compression spring is fitted onto the cylindrical part d, and the vibration damping bushing is made of vibration damping material such as rubber.

[0004] However, in practical applications, vibration damping is achieved by using a compression spring to dampen the bushing. The lower end of the compression spring directly contacts the upper side of the damping bushing. Since there is no protective structure at the contact point between the upper side of the damping bushing and the lower end of the compression spring, the lower end of the compression spring can easily damage the upper side of the damping bushing, thereby reducing the effectiveness of the damping bushing.

[0005] To address these shortcomings, a vibration damping bushing for a gas compressor is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vibration damping bushing for a gas compressor.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A gas compressor vibration damping bushing includes a flange portion, two first positioning grooves are formed on the outer side wall of the flange portion, a cylindrical portion is fixedly fitted on the upper side of the flange portion, a first groove and a plurality of second grooves connected to the first groove are formed at one end of the cylindrical portion, an annular column is rotatably fitted on the upper side of the flange portion, and an annular rubber pad is fixedly fitted on one side of the annular column.

[0009] An inverted truncated cone body is fixedly fitted to the bottom of the flange portion. A third groove is provided on one side of the inverted truncated cone body, and the third groove is connected to the first groove.

[0010] Optionally, an annular groove is provided on the upper side of the flange, and the inner wall of the annular groove is provided with an internal thread.

[0011] Optionally, the outer wall of the annular column is provided with an external thread, and the internal thread is threadedly engaged with the external thread.
