Scroll compressor lower bearing supporting structure

The invention relates to a scroll compressor lower bearing supporting structure comprising a low-pressure chamber and a high-pressure chamber arranged in the compressor. A motor is arranged in the middle of the low-pressure chamber. The motor is connected with an eccentric crankshaft. The upper end and the lower end of the eccentric crankshaft are respectively supported by an upper bearing and a lower bearing. The lower bearing is connected with a lower bearing support. The lower bearing and the lower bearing support are connected through the interference fit of the outer circumference of the lower bearing and the inner circumference of the lower bearing support. According to the scroll compressor lower bearing supporting structure, the lower bearing is directly pressed into the lower bearing support. When the lower bearing and the lower bearing support are assembled, a special fixture necessary for ensuring the concentricity of the two is eliminated, and the diameter and end face height of the lower bearing
