Description

Technical Field

[0001] This invention relates to the field of motor cover technology, specifically a motor cover for a refrigeration compressor motor. Background Technology

[0002] In a vapor compression refrigeration system, the refrigeration compressor raises the refrigerant from low pressure to high pressure and keeps it circulating. This allows the system to continuously release internal heat to an environment with a higher temperature than the system itself. The refrigeration compressor is the heart of the refrigeration system. The refrigeration system uses the compressor to input electrical energy and release heat from a low-temperature environment to a high-temperature environment. However, some existing refrigeration compressors have limitations in use due to the difficulty in lubricating the output end of the internal motor and the relatively high noise level. Therefore, a motor cover with lubrication function is needed.

[0003] The existing motor cover for a refrigeration compressor motor has the following drawbacks:

[0004] 1. Prior art document CN212850065U discloses a motor end cover, comprising: a cover body, a shaft transition hole disposed on one side of the cover body, a gear clearance hole disposed on the upper part of the shaft transition hole, two oil holes disposed between the shaft transition hole and the gear clearance hole, a sealing groove disposed around the shaft transition hole, the gear clearance hole and the two oil holes, and four bolt connection holes disposed around the sealing groove; the center lines of the shaft transition hole and the gear clearance hole are located on the length center line of the cover body, and the center lines of the two oil holes are located on the width center line of the cover body; the sealing groove includes the shaft transition hole, the gear clearance hole and the two oil holes disposed on the outer periphery of the sealing groove. The first sealing part around the oil hole and the second sealing part disposed at the outer end of the gear clearance hole are connected. The motor end cover has a simple structure and is easy to process. It can effectively seal the shaft transition hole, the gear clearance hole, the two oil holes and the oil return hole, and can realize the modularization and mass production of the motor. However, the above device does not involve lubrication measures for the motor output end, which causes wear on the surface of the motor output end after long-term use, increasing the power consumption of the motor and limiting its use. Therefore, the specific implementation of this device needs to be improved. In the prior art, a motor cover for a refrigeration compressor motor does not have certain lubrication measures, which causes the internal motor to wear more heavily at the output end after long-term use, putting a certain burden on the motor and reducing its service life. It also has certain limitations in use.
