Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning compressors, in particular to a deep groove ball bearing for air-conditioning compressors. Background Art

[0002] Air conditioning compressors compress and drive refrigerant in the air conditioning refrigerant circuit. Air conditioning compressors require the use of deep groove ball bearings. Deep groove ball bearings were originally named radial ball bearings. They are the most widely used rolling bearings. They are characterized by low friction resistance and high speed. They can be used on parts that bear radial loads or combined loads of radial and axial loads at the same time, and can also be used on parts that bear axial loads.

[0003] For example, the utility model with application number CN202122844762.8 discloses a deep groove ball bearing specially used for air-conditioning compressors. The utility model has a dust cover installed at one end of the outer ring to prevent dust from entering the interior of the machine, thereby reducing the impact of debris on the work. The dust cover is connected to the outer ring by a socket and a slot to prevent external debris from entering the bearing and affecting the rolling friction of the ball. The shoulder and the retainer are integrally formed to fix the ball and prevent the ball from gathering together when rolling inside the bearing, thereby affecting the rotation of the machine. However, when assembling this type of deep groove ball bearing, the retainer is installed on the outside of the deep groove ball bearing using more fixing bolts, resulting in more operating steps required for disassembly and maintenance, resulting in reduced maintenance and repair efficiency of the deep groove ball bearing.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a deep groove ball bearing for an air-conditioning compressor is provided. Utility Model Content

[0016] 2. The utility model provides a protective component. After the retaining frame is assembled, the installation of the side cover can be completed at the same time to protect one side of the bearing. When protecting the other side of the bearing, it is only necessary to insert the positioning column into the positioning groove. At this time, the second magnet can adsorb the iron positioning column, and the installation of the protective cover can be quickly completed to prevent dust and impurities from entering between the outer ring and the inner ring. When disassembling, it is only necessary to rotate and pull the rotating plate to facilitate the removal of the protective cover from the outer ring, and then press the end of the positioning rod to remove the positioning ring, thereby improving the convenience during operation.
