Abstract

The invention provides a coupler for improving the oil pumping effect, a compressor and an air conditioning unit. The coupler comprises a sleeve-shaped coupler body; the first end of the coupler bodyis used for sleeving a first shaft body, and the second end of the coupler body is used for sleeving a second shaft body. The coupler body is provided with an oil guiding groove, the oil guiding groove communicates with a free space in the coupler body to form an oil pool structure, and the oil pool structure is used for supplying oil to the first shaft body and the second shaft body. By applyingthe technical scheme of the invention, the oil pumping amount of shafts connected with the coupler can be effectively improved, the problems of serious abrasion, insufficient heat dissipation and thelike of the shafts and structures therewith caused by oil leakage due to insufficient oil supply are avoided, and the performance and stability of the compressor are indirectly improved.

Description

technical field [0001] The invention relates to the technical field of transmission devices, in particular to a coupling, a compressor and an air-conditioning unit for improving the oil pumping effect. Background technique [0002] In the structure of the existing rotary compressor that uses a coupling to connect multiple crankshafts, due to the increase in the number of crankshafts, the crankshaft located above the coupling cannot directly pump oil in the oil pool of the compressor, and only the crankshaft at the bottom pumps oil. It is far from meeting the pump oil requirements of the upper crankshaft. [0003] In this way, the upper crankshaft will be in a state of insufficient pump oil supply for a long time, resulting in severe wear and insufficient heat dissipation of the structural parts of the pump body due to lack of oil, which will shorten the service life and affect the performance of the compressor. Contents of the invention [0004] The embodiment of the pres...
