Bearing silencer for compressor

Abstract

The invention relates to a bearing silencer for a compressor and belongs to the technical field of silencing equipment. The bearing silencer comprises a bearing and a silencing body. The bearing comprises a non-working surface, a bearing outer ring and a bearing inner ring. The bearing outer ring is arranged on the non-working surface. The bearing inner ring is arranged in an inner cavity of the bearing outer ring. One side of the silencing body is connected with the bearing outer ring. The top portion of the silencing body is provided with bolt ports and an outer sealing gasket. Silencing cotton, a damping fin and an active carbon adsorption layer are sequentially arranged in an inner cavity of the outer sealing gasket from top to bottom. The top of the outer sealing gasket is provided with a lubricating oil inlet. According to the bearing silencer for the compressor, the better sealing effect on the bearing in the air conditioner compressor is achieved; through the design of the lubricating oil inlet, lubricating oil can be added directly, and abrasion noise of the bearing in the compressor is lowered; through a sealing device of an outward-protruding structure, the effective noise absorbing volume of the silencing cotton is expanded; the silencing cotton and the active carbon adsorption layer form a dual silencing system, so that noise generated by the bearing in the compressor is lowered to the greatest extent.

Description

technical field [0001] The invention relates to a bearing muffler for a compressor, which belongs to the technical field of muffler equipment. Background technique [0002] The muffler is an effective device installed in mechanical equipment that can block the transmission of sound waves and reduce equipment noise. The most widely used muffler for compressors currently used is composed of tubes and chambers with sudden changes in the interface. Each chamber with tubes has a Due to its own fixed frequency, when sound waves of different sound frequencies enter the tube, only sound waves close to the natural frequency of the tube can be transmitted in, and other sound waves cannot pass through the mesh, refracting back and forth, resulting in loss of capacity, thereby filtering some frequency noise, the bearing is in the The part that fixes and reduces the friction coefficient of the load during the compressor transmission process can also be said that when other parts move rel...

[0002] The muffler is an effective device installed in mechanical equipment that can block the transmission of sound waves and reduce equipment noise. The most widely used muffler for compressors currently used is composed of tubes and chambers with sudden changes in the interface. Each chamber with tubes has a Due to its own fixed frequency, when sound waves of different sound frequencies enter the tube, only sound waves close to the natural frequency of the tube can be transmitted in, and other sound waves cannot pass through the mesh, refracting back and forth, resulting in loss of capacity, thereby filtering some frequency noise, the bearing is in the The part that fixes and reduces the friction coefficient of the load during the compressor transmission process can also be said that when other parts move relative to each other on the shaft, it is used to reduce the friction coefficient during the power transmission process and keep the shaft center position fixed Machine parts, with the development of compressor technology, users have higher and higher requirements for the quality of bearing sealing rings. Not only are the bearings required to have good sealing, long life, and good heat dissipation, but they are also required to have low vibration, low noise, and low temperature. The performance indicators of liter, grease leakage and dust prevention are good, especially in recent years, with the development and application of ultra-high-speed electric tools (above 30000r / min) in the air-conditioning industry, on some supporting compressors, the bearing noise generated by the bearing Larger, and as a supporting bearing noise reduction device, its noise reduction performance is poor, and it cannot eliminate the noise generated by the compressor bearing, resulting in noise pollution
