“…Thus, the use of automatic temperature control means of bearing assemblies should be based on the development of measuring equipment based on microcontrollers and software that allows measuring and comparing not only the temperature value but also the rate of its change [14][15][16][17][18][19][20]. It is necessary to develop an appropriate subroutine in the software algorithm to eliminate errors of the second kind when setting a stable temperature.…”

The article developed a methodological basis for implementing automatic diagnostics based on thermal analysis of bearing assemblies. The diagnostic criteria of the technical operation condition and the procedure for determining the temperature ratio inside and outside the bearing unit based on the finite element analysis (FEA) of stable thermal conductivity have proven to be justified. Method of simulation of stable thermal conductivity of bearing units using KOMPAS-3D software and APM FEM finite element analysis module is proposed. The developed method was tested in practice and verified based on the results of theoretical and experimental studies. The developed method enables the determination of the relationship between the observed temperature on the surface of the bearing units and the friction temperature in the wear zone.

“…KS Kim et al 14 estimated the equilibrium temperature on an angular contact ball bearing in a spindle system, considering the frictional torque of the bearing, which was calculated using the finite element method (FEM). IA Zverev and AR Maslov 15 studied the spindle speed and load, and the preliminary tension of the bearing was found to have deep effects on the frictional and thermal characteristics of a spindle. However, the currently developed dynamic models of spindle-bearing systems did not consider the small thermal deformations of ceramic in some hightemperature environments.…”

Ceramic bearings have a good dynamic output performance under an ultra-high, ultra-low temperature due to their small deformation property. Based on the Harris and Palmgren empirical equation, this article establishes the thermal transfer model of a ceramic motorized spindle. The thermal deformation of a ceramic angular contact ball bearing is calculated. A dynamic and thermal coupling model of the ceramic motorized spindle is built using the Hertz contact theory, which can determine the optimal preload force under different rotating speed conditions. The influence of different temperatures, preload, and rotation speeds on the bearing vibration characteristics was studied. The accuracy of the dynamic and thermal coupling model was verified by the motorized spindle experimental platform. The results show that the thermal deformation of the bearing is an important influencing factor for the output of the dynamic characteristics. Considering the thermal displacement of the bearing, the simulation accuracy of the ceramic motorized spindle-bearing system is in good agreement with the experimental results. By adjusting the bearing preload, the parameters of the rotating speed can effectively reduce the temperature rise and suppress the vibration. The spindle-bearing system model provides a theoretical basis for the dynamic development of a high-speed ceramic bearing.
