▎ 摘　　要

NOVELTY - The bearing has a silicon dioxide film (2) fixedly connected with a bearing body (1). An outer surface of the bearing body is formed with a silicon dioxide hole. The silicon dioxide film is coated with a conducting graphene function film (3). The conducting graphene function film is formed with a K-shaped structure thermocouple film. A signal transmitting and processing device is connected with a graphite end and a nickel-chromium end. The electroconducting graphene functional film is coated with a silicon nitride protective film (4). USE - Composite film system structure temperature self-sensing bearing. ADVANTAGE - The bearing has better bearing performance, and has accurate detection characteristics and better heat transmission property characteristics, and provides better technical condition. DESCRIPTION OF DRAWING(S) - The drawing shows a front view of a composite film system structure temperature self-sensing bearing.
