Embedded Water-lubricated Bearing Temperature Wireless Monitoring System

Abstract

For the ship lubrication system, different water temperatures not only affect the viscosity coefficient of the water, but also cause additional thermal deformation of the rubber bearing, and in serious cases, it also affects the normal operation of the ship lubrication system. However, the water film has a closed area, various bearing structures, complex operating conditions, and limited existing monitoring methods, resulting in accurate temperature data that is not easy to obtain. In order to solve the above problems, a thin-film temperature sensor was proposed to be embedded in the water-lubricated bearing and wireless communication technology was applied, and a monitoring system was developed to achieve real-time monitoring of the bearing temperature signal. Firstly, the temperature monitoring system and bearing system are described, then the temperature sensor is calibrated, and finally the system is designed and tested through software and hardware. The results show that the method of the wireless temperature monitoring system in this paper is feasible.
