AI Technical Summary
The uneven distribution of lubricating oil on the moving disc of existing scroll compressors leads to poor lubrication of the friction pair, which may result in dry friction, affecting the wear of parts and noise. In addition, the traditional reinforced design increases the mass and inertia of the moving disc.
A honeycomb-shaped oil reservoir is set on the main body of the moving disc to store and continuously release lubricating oil. Combined with the mounting groove and sealing strip on the vortex wall, it improves the lubrication of the friction pair and reduces abnormal wear and vibration.
It achieves stable lubrication in the friction pair area, reduces wear, lowers the mass and inertia of the moving plate, improves the operating stability and lifespan of the compressor, and reduces noise and vibration.
