Description

Technical Field

[0001] The utility model relates to the field of compressors, and more specifically, to a lubricating structure for a compressor core of a vehicle-mounted air-conditioner. Background Art

[0002] The automotive air-conditioning compressor movement is the core component of the automotive air-conditioning system. It is responsible for compressing the refrigerant from a low-pressure state to a high-pressure state, thereby realizing the refrigeration cycle. Air-conditioning compressors are divided into many types according to the different rotors. Common ones include vane compressors, swash plate compressors, scroll compressors, etc.

[0003] A vane compressor generally includes a shell, on which an air inlet valve, an air outlet valve and a drive shaft are rotatably arranged. A rotor is fixedly connected to the drive shaft, and a number of blades are slidably arranged on the rotor. A chamber for the rotation of the shaft is provided in the shell, and the chamber and the rotor are eccentrically arranged. When the rotor rotates, the blades will be thrown out. The refrigerant is gradually squeezed and compressed by the rotation and sliding of the blades to reach a high-pressure state. However, after long-term use, the blades and the inner wall of the chamber will wear due to insufficient lubrication. In severe cases, the air-conditioning compressor will malfunction and cannot operate normally.

[0004] Based on the above, the purpose of the present invention is to provide a vehicle-mounted air-conditioning compressor core lubrication structure to solve the above problems. Utility Model Content

[0024] A vehicle air-conditioning compressor core lubrication structure, such as Figure 1-Figure 3 As shown, it includes a shell 1, an air inlet valve, an air outlet valve (not shown) and a driving shaft 2 that is rotatably connected to the shell 1, a rotor 3 is fixedly connected to the driving shaft 2, a plurality of chutes 4 are provided on the rotor 3, and blades 5 are slidingly provided in the chutes 4. A chamber 6 for the rotor 3 to rotate is provided in the shell 1, and the chamber 6 and the rotor 3 are eccentrically arranged. An oil storage chamber 7 is provided on the shell 1, and an oil inlet pipe 8 and an oil outlet groove 9 are provided on the oil storage chamber 7. The oil inlet pipe can be connected to other lubricating oil storage components, and a sealing cover can also be added to regularly refuel the oil storage chamber. The oil outlet groove 9 is annularly arranged, and the oil outlet groove 9 connects the oil storage chamber 7 with the chamber 6. The inner walls on both sides of the chute 4 are provided with flow grooves 10 that are connected to the oil storage chamber.

[0025] Furthermore, a sealing ring 11 is slidably connected in the oil storage chamber, and the sealing ring 11 is fixedly connected to the rotor 3. The sealing ring 11 is provided with a number of connecting grooves 12 whose number and position correspond to the flow groove 10, and the two sides of the connecting groove 12 are respectively connected to the oil storage chamber 7 and the flow groove 10.

[0026] Furthermore, a filter screen 15 is installed on the oil outlet tank.

[0027] Furthermore, a sponge is provided in the flow groove 10, and the sponge is a high-temperature resistant sponge. Limiting parts are provided on both sides of the sponge, and a limiting groove 13 for inserting the limiting part is provided on the flow groove 10.

[0028] Furthermore, a portion of the drive shaft 2 located in the oil storage chamber is fixedly connected to a plurality of stirring rods.

[0029] Furthermore, a contraction groove is formed on the blade 5 , and an elastic member 14 is provided in the contraction groove. The elastic member is made of high temperature resistant rubber.

[0030] Working principle: The user can pour the lubricating oil into the oil storage chamber 7 through the oil inlet pipe. The lubricating oil in the oil storage chamber 7 can flow to the flow grooves 10 on both sides of the inner wall of the chute 4 through the oil outlet groove. The filter 15 will filter the lubricating oil to prevent impurities from getting stuck between the blades 5 and the chute 4. When the blades 5 come into contact with the sponge in the flow groove 10 during the reciprocating movement, the sponge will smear the lubricating oil on the blades 5, so that both sides of the blades 5 are lubricated. During the reciprocating movement, the blades 5 will gradually smear the lubricating oil on the inner wall of the chute 4, and will gradually throw the lubricating oil to the inner wall of the chamber 6 through centrifugal force, so that the inner wall of the chamber 6 is also lubricated. When the drive shaft 2 drives the rotor 3 to rotate, the drive shaft 2 will also drive the stirring rod to rotate. The stirring rod will stir the lubricating oil to prevent the lubricating oil from being stratified due to long-term standing. The setting of the shrinkage groove and the elastic part 14 can prevent the blades 5 from getting stuck due to thermal expansion when the temperature is too high.
