Compressor bottom corner vibration damping mat

Abstract

The invention discloses a vibration damping pad at the bottom corner of a compressor, and comprises a top layer, a middle layer and a bottom layer, which is coaxial and the diameters of which increase in sequence. A connecting pole is formed between the top layer and the middle layer, and a groove is formed in the middle of the middle layer. The bottom end of the connecting pole is in the groove, and integrated with the middle layer in the groove. The top layer, the connecting pole, the middle layer and the bottom layer are formed in an integrated way, and through-holes are formed at the center of the top layer, the connecting pole, the middle layer and the bottom layer. A rubber layer and a spring are also arranged and fit into the perimeter of the connecting pole formed between the top layer and the middle layer. The rubber layer is at the upper end of the spring, while the lower end of the spring is embedded into the groove in the middle of the middle layer. The invention is wholly made of rubber materials, and can meet the requirement for high frequency damping by a compressor. Meanwhile, the spring arranged between layers of the vibration damping pad can reduce the low-frequency vibration of the compressor. Thus, the vibration-damping pad of the invention can meet the requirement for both the high-frequency damping and the low-frequency vibration of a compressor.

Description

technical field [0001] The present invention relates to a compressor. In particular, it relates to a vibration-damping pad for the bottom corner of a compressor that not only meets the high-frequency damping requirements of the compressor, but also reduces the low-frequency vibration of the compressor. Background technique [0002] Rotary compressors are widely used in various refrigerators and air conditioners. The rotary compressor sucks the gaseous refrigerant evaporated by the evaporator, compresses it to a saturated state, and then discharges it to the working system of the refrigerant. The rotary compressor is a compressor that can continuously suck and discharge gaseous refrigerant. [0003] Fig. 1 is a longitudinal sectional view of a conventional rotary compressor. [0004] As shown in Figure 1, the existing rotary compressor includes: a casing 1 with a certain internal volume, a motor part installed inside the casing 1 to generate a driving force, and the refrige...

AI Technical Summary

Problems solved by technology

Although the above-mentioned vibration damping pad is made of rubber material, due to its structure, the vibration damping effect of the vibration damping pad is poor, especially the suppression effect on low frequency vibration is even worse.
