Document Type and Number:
WIPO Patent Application WO/2019/069886
Kind Code:
A1
Abstract:
Provided is a two-way-rotating scroll compressor with which the life of a synchronous drive mechanism can be extended. This compressor comprises a synchronous drive mechanism that transmits drive force from a drive-side scroll member to a driven-side scroll member so that the drive-side scroll member and the driven-side scroll member undergo rotational movement in the same direction and at the same angular speed. The synchronous drive mechanism is provided with a crank pin (15) and a roller bearing (18) that rotatably supports a shaft (15b) of the crank pin (15). The roller bearing (18) is provided with an inner ring (18b) that is fitted over the shaft (15b) and an outer ring (18a) that is fitted over a first side plate (27) which supports the shaft (15b). A seal member (40), which extends to a side part of the inner ring (18b), is fixed to a side part of the outer ring (18a).
