Description

Technical Field

[0001] The utility model relates to a hydrogen fuel cell air compressor stator and rotor vertical disassembly and assembly device, belonging to the technical field of hydrogen fuel cell air compressors. Background Art

[0002] As an important component, the air compressor (hereinafter referred to as "air compressor") mainly provides a steady stream of compressed air for hydrogen fuel cells and is known as the lungs of hydrogen fuel cell engines. The air compressor has a small and compact structure, and contains multiple precision-made parts such as the motor stator, air foil bearing, and rotor. The air compressor bearing parts are connected to the outside, and the assembly accuracy requirements are relatively high.

[0003] The motor housing of the air compressor is equipped with the motor stator. The core of the rotor part is magnetic steel and is generally magnetized. When the rotor part passes through the area of ​​the motor stator, it will generate a strong magnetic force. Therefore, the traditional hand-held rotor assembly method is used to assemble or disassemble the stator and rotor, which will not only affect the assembly and disassembly efficiency, but also bring certain quality and safety risks. There are mainly the following aspects:

[0004] 1. In order to ensure the working performance of the air compressor, the radial clearance between the outer diameter of the rotor component and the inner diameter of the radial foil bearing is generally designed to be very small (<0.2mm). When the handheld rotor passes through the air bearing area, it is very easy to scratch the foil of the bearing, damaging the surface coating of the foil; and due to the existence of magnetic force, the rotor is very easy to tilt or violently collide with the bearing, causing the foil of the air bearing to be flattened, directly damaging or failing, or affecting the service life of the bearing;

[0005] 2. The shaft head area of ​​the rotor component is thin and has poor rigidity. When the rotor component passes through the stator area of ​​the motor, due to the existence of magnetic force, the shaft head is easy to hit the iron core or copper coil, directly causing the rotor component to bend or scrap, or scratch the surface of the copper coil, causing the risk of leakage;

[0006] 3. Due to the strong magnetic force, it is very easy to pinch your fingers when the rotor and the iron core are adsorbed and collided;

[0007] 4. Manual assembly of rotor parts has low success rate and efficiency.

[0008] Therefore, it is necessary to design a simple, safe, reliable and efficient device to assist in the assembly and disassembly of the air compressor stator and rotor, protect the triple safety of bearings, rotor components and personnel, and increase the service life of the air compressor stator and rotor.
