Abstract
A bearing assembly is provided with an improved mounting for a temperature sensor for monitoring a temperature of a race of the bearing. The assembly includes a temperature sensor assembly mounted to the race of the bearing and a thermal insulator arranged to thermally insulate the sensor from heat exchange with the surrounding environment and/or neighbouring components to which the bearing or assembly is mounted, in order to improve accuracy, reliability and speed of response of the temperature sensor readings.
Claims23
A bearing assembly comprising:
- a bearing, having a first race and a second race;
- a temperature sensor assembly, comprising a temperature sensor, mounted to one of the first race and the second race;
- a first thermal insulator arranged to thermally insulate the temperature sensor from its surroundings;
- and
- a housing for the temperature sensor;
- wherein the temperature sensor and the first thermal insulator are located between the housing and the race of the bearing.
