Abstract: A scroll compressor includes a first scroll, the first scroll including a first end plate and a first scroll wrap extending from the first end plate along a first direction; a second scroll, the second scroll including a second end plate and a second scroll wrap protruding from the second end plate along a second direction opposite to the first direction, the second scroll wrap and the first scroll wrap cooperating to form a compression cavity used for compressing a medium; a support located at a side of the second scroll away from the first scroll; a motor; and a driving member rotatably supported by the support and located at the side of the second scroll away from the first scroll. The motor drives the first scroll to rotate through the driving member, and the first scroll drives the second scroll to rotate. The scroll compressor is compact in structure, small in volume, and light in weight.

Abstract: A scroll compressor (1000), includes a housing (1200); a first scroll plate (1300) fixed to the housing (1200), the first scroll plate (1300) including a first end plate (1310) and a first scroll wrap (1320); a second scroll plate (1400), the second scroll plate (1400) including a second end plate (1410) and a second scroll wrap (1420), the first scroll wrap (1320) extending from the first end plate (1310) toward the second end plate (1410) and the second scroll wrap (1420) extending from the second end plate (1410) toward the first end plate (1310) such that the second scroll wrap (1420) and the first scroll wrap (1310) fit with each other to form a compression cavity for a compression medium; an electric motor (80); and a screw oil pump (100) driven by the motor (80), wherein the top end of the screw oil pump (100) fits with the second scroll plate (1400) and the lower end of the screw oil pump (100) extends into an oil bath located at the bottom of the housing (1200).

Abstract: A compressor is provided and includes a first scroll and a second scroll matching with each other to form a compression chamber. The first scroll includes a first end plate and a first scroll wrap extending from the first end plate toward the second scroll, the second scroll includes a second end plate and a second scroll wrap extending from the second end plate toward the first scroll; and a motor for driving the first and second scroll to co-rotate so as to compress a fluid entering the compression chamber; the first scroll wrap is configured with the shape of a first profile such that a center of mass of the first scroll coincides or approximately coincides with a rotation center of the first scroll; and/or, the second scroll wrap is configured with the shape of a second profile such that a center of mass of the second scroll coincides or approximately coincides with a rotation center of the second scroll, each of the first profile and the second profile being defined by a hybrid profile.

Abstract: A scroll compressor includes a compressor shell; a frame (4) installed in the compressor shell; a first scroll (5) located in the compressor shell; and a second scroll (6) located in the compressor shell and being co-rotatable with the first scroll (5), to define a compression chamber (56) between the first scroll (5) and the second scroll (6), the second scroll (6) having a hub (41) that extends downward from a lower surface thereof; a transformer flange (8) supported on the frame and supporting the first scroll (5) and the second scroll (6), the transformer flange (8) being connected to the first scroll (5); an actuating mechanism (7) installed in the compressor shell and connected to the transformer flange (8), for driving the transformer flange (8) to rotate, so that the first scroll (5) and the second scroll (6) are driven to co-rotate; a crankshaft (9) assembly located in the transformer flange (8) and including an oil screw (10), an upper end (101) of the oil screw (10) being fitted with a hub (61) of

Abstract: In a scroll machining method, a scroll has a disc-like end plate and a scroll wall extending from a first side surface of the disc-like end plate, and the scroll is driven to rotate around a center axis C of the scroll, and a first cutter machines a side wall surface of the scroll wall while the scroll is rotating. The first cutter is a non-rotary cutter. When the scroll is machined, the scroll rotates around its center axis, and the first cutter does not rotate around its axis, thereby improving the scroll's machining precision and machining efficiency.
