Low power consumption high speed heavy load tilting pad bearing with cold temperature characteristics

Abstract

The application discloses a low-power-consumption high-speed heavy-load tilting-pad bearing with cold temperature characteristics, belongs to the technical field of tilting-pad bearings, and aims at solving the technical problems of poor self-lubricating performance and cold temperature characteristics of the prior art tilting-pad bearing and improving the cold temperature characteristics of the tilting-pad bearing. The low-power-consumption high-speed heavy-load tilting-pad bearing with cold temperature characteristics comprises a shell, a plurality of tilting pads are arranged on the inner side of the shell along the length direction of the shell, and a plurality of liquid guide holes are arranged on the outer side of the shell and correspond to the plurality of tilting pads. The tilting pad comprises a pad sleeve, a ball support is arranged at the top center of the pad sleeve, a plurality of communication grooves are arranged at the top of the pad sleeve and are in communication with the internal cavity of the pad sleeve, and the two ends of the communication grooves extend to the outer sides of the pad sleeve. The application optimizes the structure of the tilting pad, effectively improves the self-lubricating performance of the tilting-pad bearing, and shows good cold temperature characteristics under high-speed rotation.
