WIPO Patent Application WO/2020/052141

Kind Code:

A1

Abstract:

Provided are a liquid spraying ring (40) and a refrigerant lubricating bearing assembly. The liquid spraying ring (40) comprises a ring body (41), wherein the ring body (41) is provided with a liquid storage cavity (411) and a plurality of liquid guide holes (412); the liquid storage cavity (411) surrounds an axis of the ring body (41) for one circle, inlets of the liquid guide holes (412) are in communication with the liquid storage cavity (41), and outlets of the liquid guide holes (412) face towards an end face of a bearing (30) to be lubricated; and the plurality of liquid guide holes (412) are uniformly distributed at intervals in the circumferential direction of the ring body (41). By means of arranging the liquid storage cavity (411), which surrounds the axis of the ring body (41) for one circle, to be in communication with each of the liquid guide holes (412), the refrigerant is dispersed into each of the liquid guide holes (412) through the liquid storage cavity (411), and the outlets of the plurality of liquid guide holes (412) are uniformly distributed at intervals in the circumferential direction of the ring body (41), so that the liquid spraying ring (40) can uniformly spray a liquid onto the bearing (30) to be lubricated, thereby improving the lubrication effect.
