An analysis of the influence of the change of temperature of a rotor’s system with bearings of sliding friction to the work of a searching system is presented in this paper. Experimental research to gauge the clearance of change between a rotor and bearing subject to change of temperature and frequency of rotor’s rotating is also presented. A special rig and special implements of measurement for doing measurements is included. Experimental measurements done according to the specially made up methodology is in this paper. Also, the article describes and gives the principal system of measurement and analysis methodology to do the experiment and an analysis was done of results and the gauge of consistent pattern of changes of the searched parameters.
