Document Type and Number:
WIPO Patent Application WO/2024/082797
Kind Code:
A1
Abstract:
The present application provides a bearing lubricating structure and a rotating device. The bearing lubricating structure comprises a rotating member; a plurality of bearing bushes, the plurality of bearing bushes being arranged in an annular array around the rotating member; and a plurality of heat-insulation oil supply assemblies, the heat-insulation oil supply assemblies being located between adjacent bearing bushes, wherein each heat-insulation oil supply assembly comprises an oil spraying pipe and an oil separation plate, the oil separation plate is in contact with the rotating member, and the oil spraying pipe supplies oil to at least one side of the oil separation plate. According to the present application, the heat-insulation oil supply assemblies are arranged between adjacent bearing bushes, and the adjacent bearing bushes are separated by means of the oil separation plates of the heat-insulation oil supply assemblies, such that the phenomenon that hot oil is transmitted between every two adjacent bearing bushes is avoided, and the amount of cold oil entering the bearing bushes can be increased while the amount of hot oil entering the bearing bushes is reduced, thereby facilitating reduction of the working temperature of the bearing bushes; in addition, the oil spraying pipe supplies oil to the bearing bushes for lubricating in a spraying mode, such that there is no need to soak the rotating member and a bearing in a lubricating medium, thereby avoiding foam and oil mist caused by agitation of the rotating member.
