COUNTERBALANCE ASSEMBLY FOR SCROLL COMPRESSOR, AND SCROLL COMPRESSOR

WIPO Patent Application WO/2021/203638

A1

A counterbalance assembly for a scroll compressor, and a scroll compressor (1). The scroll compressor (1) comprises a compressor mechanism and a drive shaft (16). A counterbalance assembly (5) comprises: a bushing, the bushing (51) being arranged between a drive linking part and a drive part; and a counterbalance component (50), the counterbalance component (50) comprising a base mounted on the bushing (51) or integrally formed with the bushing (51) and a counterbalance part (502) extending out from the base. The counterbalance part (502) rotates along with the drive shaft (16) and thus has an oil mixing face (5022) that acts as a windward face. At least one oil inlet (5027) is provided on the oil mixing face (5022), at least one oil outlet (5028) is arranged on a top end face (5023) of the counterbalance part (502), and at least one oil passage (5029) extending from the at least one oil inlet (5027) to the at least one oil outlet (5028) is arranged inside the counterbalance part (502). The present structure is able to provide better balance of motion and is able to implement better oil mixing and oil transmission effects, while at the same time markedly reducing the power consumption of oil mixing, and being simple in structure and easy to process and manufacture.
