Abstract

The invention provides a scroll compressor which comprises a crankshaft, an upper end ring and a balance block, wherein the crankshaft is internally provided with a through eccentric through hole, and the side wall of the crankshaft is provided with an inclined oil channel; the upper end ring is fixedly connected with the crankshaft, the upper end ring is provided with an oil channel connecting part matched with the inclined oil channel, and the inclined oil channel is communicated with the eccentric through hole and the oil channel connecting part; the balance block is fixedly connected with the upper end ring and the balance block is provided with an oil deposition part communicated with the oil channel connecting part. According to the scroll compressor, partial lubricating oil reflowing from a main support frame is intercepted, is stored in the oil channel connecting part and the oil deposition part and is conveyed through the inclined oil channel of the crankshaft, so that the lubricating oil can be sufficiently supplied to all parts needing to be lubricated, the defect that the lubricating oil is supplied from the lower end of the crankshaft is overcome, the time of supplying oil upwards to the compressor is shortened, and the oil supply capability of the compressor is improved.

Description

technical field [0001] The present invention relates to a scroll compressor. Background technique [0002] Scroll compressors are high-efficiency, low-noise compressors widely used in the field of air conditioning. A fully enclosed scroll compressor generally consists of the following parts, that is, a shell forming a closed space, a compression mechanism for compressing refrigerant, and an electric motor for powering the compression mechanism. Such as figure 1 Shown is a schematic cross-sectional view of an existing scroll compressor. The compressor adopts a centrifugal oil supply method. The crankshaft 90 has a long and narrow eccentric through hole 910. An oil suction rotary vane 150 is installed at the lower end of the eccentric through hole 910. The lower end of the crankshaft 90 is straight. Insert it into the bottom oil groove Y1, the motor drives the crankshaft 90 to rotate clockwise, and the oil suction rotary vane 150 fixed at the lower end of the eccentric throu...
