Abstract
A rotor assembly and a compressor are provided. The rotor assembly has a crankshaft, a rotor core, a balance weight and an oil baffle shield. The rotor core is provided with a vent hole. The vent hole extends through the rotor core along an axial direction of the rotor core. The balance weight is located at one end of the rotor core approximate to an oil sump of the compressor. The oil baffle shield is arranged to cover the balance weight and is provided with a central opening. The crankshaft extends through the central opening. An accommodating space is defined between the oil baffle shield and the rotor core. The accommodating space is communicated with the vent hole.
Claims11
A rotor assembly applicable to a compressor, comprising:
- a crankshaft;
- a rotor core provided with a vent hole, wherein the vent hole extends through the rotor core along an axial direction of the rotor core;
- a balance weight arranged at one end of the rotor core towards an oil sump of the compressor;
- and
- an oil baffle shield comprising an annular oil baffle portion with a circumferentially constant radial section geometry, wherein the oil baffle shield is configured to at least partially cover the balance weight and is provided with a central opening, wherein the crankshaft extends through the central opening with clearance to form a gap for refrigerant and oil to flow between the crankshaft and the central opening,
- wherein an accommodating space is defined between the oil baffle shield and the rotor core, and the accommodating space is communicated with the vent hole, the oil baffle shield configured to communicate a mixture of refrigerant and oil through the vent hole.
