Example Embodiment

[0034] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in a variety of different ways defined and covered by the claims.

[0035] As an embodiment of the present invention, the present invention provides a rotary support lubrication structure of a rotary compressor. Such as Figure 4 The slewing support lubrication structure shown includes a crankshaft. The crankshaft is provided with an oil passage 8 extending in the axial direction of the crankshaft. The crankshaft includes a first shaft section 4, a second shaft section 5, and a first shaft section 4 and a second shaft section. The eccentric shaft section 6 between the shaft sections 5; the upper end surface and the lower end surface of the cylinder (not shown) of the rotary compressor are respectively provided with a first bearing 1 and a second bearing 2, the first bearing and the second bearing Support the fi...

Abstract

The invention provides a rotary supporting lubrication structure of a rotary type compressor, which comprises a crankshaft, an oil duct extended along the axial direction of the crankshaft is provided in the crankshaft, the crankshaft comprises a first shaft t segment, a second shaft segment and an eccentric shaft segment; a first bearing and a second bearing are respectively arranged on an upper end face and a lower end face of a cylinder of the rotary type compressor, the first bearing and the second bearing are respectively support the first shaft segment and the second shaft segment, the eccentric shaft segment is positioned in the cylinder, an annular oil chamber is arranged between a first annular contact part and a second annular contact part; a first end of the first shaft segment is contacted to the annular oil chamber arranged in the first bearing, the contact part of the first bearing and the crankshaft is divided into a first contact part and a second contact part, so that lubricating oil can lubricate the first contact part and the second contact part through the annular oil chamber, and the good lubrication effect can be reached.

Description

Technical field [0001] The invention relates to the field of rotary compressors, and more specifically, to a rotary support lubrication structure of a rotary compressor. Background technique [0002] figure 1 It shows a schematic diagram of a rotary support lubrication structure of a rotary compressor in the prior art. Such as figure 1 As shown, the slewing support lubrication structure includes a crankshaft supported on the first radial sliding bearing 1 and the second radial sliding bearing 2 to ensure that the crankshaft can stably and reliably achieve refrigerant compression under the drive of the motor . Wherein, the lower end of the eccentric section of the crankshaft conflicts with the end surface of the second radial sliding bearing 2 so that the end surface of the second radial sliding bearing 2 forms a thrust surface 3 to prevent the crankshaft from moving in its axial direction. [0003] figure 2 A schematic diagram showing the lubrication structure of the slewing sup...
