Samsung patents scroll compressor design with dual bearings for better support
This patent describes a specific internal structure for a scroll compressor, a type of pump used in cooling systems. It features a rotating shaft supported by two bearings arranged one above the other, along with a detachable support ring that holds the first bearing in place.
In the filing’s own words
A scroll compressor can include a frame including a shaft hole, a fixed scroll on an upper side of the frame, an orbiting scroll between the fixed scroll and the frame, a lower surface of the orbiting scroll including a boss inserted into the shaft hole, a rotatable shaft including an eccentric portion inserted into the boss and inserted into the shaft hole, a first bearing in the shaft hole between the shaft hole and a bearing support coupled to an outer circumferential surface of the rotating shaft, an inner circumferential surface of the first bearing being supported by an outer circumferential surface of the bearing support, the bearing support being separatable from, and couplable to, the rotating shaft, and a second bearing between the boss and the eccentric portion so that a location of the second bearing overlaps the first bearing in an axial direction of the rotatable shaft.
What exactly they claim (claim 1)
1. A scroll compressor comprising: a main frame including a shaft hole; a fixed scroll disposed on an upper side of the main frame; an orbiting scroll disposed in a space formed by the fixed scroll and the main frame, a lower surface of the orbiting scroll including a boss having an opening therein and the boss being inserted into the shaft hole of the main frame; a rotatable shaft including an eccentric portion inserted into the opening of the boss and an upper end of the rotatable shaft including a step portion, the rotatable shaft inserted into the shaft hole of the main frame; a bearing support coupled to the step portion of the rotatable shaft, the bearing support being separatable from, and couplable to, the rotatable shaft; a first bearing disposed in the shaft hole between inner surface of the shaft hole and the bearing support, an inner circumferential surface of the first bearing being supported by an outer circumferential surface of the bearing support; and a second bearing disposed between an inner surface of the boss and an outer surface of the eccentric portion of the rotatable shaft, such that the second bearing overlaps the first bearing in an axial direction of the rotatable shaft.
