The research of influence of operation temperature on the thermal expansion
and main parameters of radial ball bearings is presented in this paper. The
main bearing parameters are identified in accordance with the increasing
requests concerning stability and load capacity. A series of Finite Element
Analyses is performed for quasi-static analysis of all identified bearing
parameters during contact period in referent temperature. Then, the
dependence of bearing material characteristics on the operation temperature
is discussed. Few series of Finite Element Analyses are performed for a
particular radial ball bearing type, with characteristics in accordance with
manufacturer specifications, for several operation temperatures. These two
problems analyses include consideration of relation between the initial
radial clearance, thermal expansion strains and contact deformations of the
parts of the bearing assembly. The results for radial ball bearing parameters
are monitored during a ball contact period for different temperatures and the
appropriate discussion and conclusions are given. The conclusions about the
contribution of developed procedure in defining the optimum operation
temperature range are shown.
