The second scroll member (78) includes a second end plate (86) and a second spiral wrap (88) extending from the second end plate (86) and intermeshed with the first spiral wrap (82) to define compression pockets (122) therebetween. The first bearing housing (14) supports the first scroll member (76) for rotation about a first rotational axis (A1). The second bearing housing (16) supports the second scroll member (78) for rotation about a second rotational axis (A2) that is parallel to and offset from the first rotational axis (A1). The motor assembly (20) is disposed axially between the first and second bearing housings (14;16) and includes a rotor (100) attached to the first scroll member (76). The rotor (100) surrounds the first and second end plates (80;86).

摘要： A disc-like spacer 78 arranged below a first roller bearing 54 rotatably supporting a driven crankshaft 52 that forms an anti-rotation system 50 is formed with a plurality of notches 78a in the circumferential direction. A spot face 80 is provided to face the outer circumferential surface of the spacer 78, and communication holes 82 and 86 are drilled on the outer circumferential side of the spot face 80 to extend in the axial direction of the scroll. Also formed is a communication hole communicating the communication hole 86 with the first roller bearing 54 via the notches 78a. A grease nipple 88 is mounted to the communication hole 86. To replenish grease, the fixed scroll 10 is removed from the housing 40 such that the orbiting scroll 20 is exposed, and grease is injected from the grease nipple 88 into the first roller bearing 54 with a grease gun.

摘要： Disclosed are an exhaust bearing seat, a screw compressor and an air-conditioning unit. The exhaust bearing seat is provided with a discharge port (1), wherein an opening of the discharge port (1) is orientated in such a way that, if the exhaust bearing seat is sheathed in a housing, gas exhausted from the discharge port (1) has a component which rotates along an inner wall of the housing and around an axial direction of the housing. The discharge port (1) is able to guide the gas flow to rotationally flow along the inner wall of the housing body and around the axial direction of the housing, which extends the flow path of the gas flow inside the housing, and facilitates the reduction of noise of the gas flow pulsation.

摘要： A low-backpressure rotary compressor (100) comprises a housing (10), a compression mechanism, an oil separator (18) for performing oil-gas separation on a refrigerant discharged from a cylinder (12), and an oil pool (5) for accommodating lubricating oil separated by the oil separator (18). The compression mechanism comprises a cylinder assembly, a piston (13), a slide sheet (14), a main bearing (11) and an auxiliary bearing (12). The cylinder (12) has a slide-sheet chamber (2), the slide-sheet chamber (2) is provided with an oil supply hole, and when the slide sheet (14) moves in a reciprocating manner, the tail end of the slide sheet (14) stretches into or out of the slide-sheet chamber (2) so that the internal volume of the slide-sheet chamber (2) changes between a maximum volume V2 and a minimum volume V1. The oil pool (5) communicates with the oil supply hole via a slide-sheet oil supply path (3). The ratio of the maximum volume V2 to the minimum volume V1 satisfies the following relationship: 35%≤V1/V2≤85%.
