COMPRESSOR HAVING A LOWER FRAME AND A METHOD OF MANUFACTURING THE SAME

摘要

A compressor having a lower frame and a method of manufacturing the same are disclosed. The compressor may include a cylindrical shell, a rotational shaft rotatably mounted in the cylindrical shell, a rotor and a stator that rotates the rotational shaft, a compression device driven by the rotational shaft, a lower bearing configured to rotatably support one side of the rotational shaft, a lower frame configured to support the lower bearing, the lower frame being configured to be press-fitted into a lower end portion of the cylindrical shell, and a base configured to seal the lower end portion of the cylindrical shell. The lower frame may include a main body configured to be press-fitted onto an inner circumferential surface of the cylindrical shell and a flange that extends from the main body, the flange being configured to limit a press-fit depth by contacting the lower end portion of the cylindrical shell.

主权项

1. A method for manufacturing a compressor, the method comprising;
providing a cylindrical shell, a lower bearing, a lower frame, and a base, the lower frame having a main body configured to contact an inner circumferential surface of the cylindrical shell; coupling the lower bearing to the lower frame, such that a center of an inner circumferential surface of the lower bearing is aligned with a center of the main body of the lower frame; press-fitting the lower frame into a lower end portion of the cylindrical shell; mounting the lower frame press-fitted in the cylindrical shell onto the base; and attaching the lower end portion of the cylindrical shell and the base to each other.
