Influence of essential parameters on the radial clearance and stress-strain states in ball bearings
Šperka, Václav ; Vrbka, Jan (referee) ; Fuis, Vladimír (advisor)
Master thesis is focused on the research of influence of selected substantial parameters on stress – strain states in the deep groove radial ball bearing. The influence of radial load is analyzed, such as the influence of size of the bearing and row of the bearing, also influence of radial clearance is quantified. Next, the influence of thermal distribution in the bearing is analyzed for different combinations of thermal distributions and radial clearances. Conclusions from analyses are then used in the last task – suggestion of radial clearance for customer – specified assembly. Problem is solved using the finite element method (FEM) in pre/post processor MSC.Patran and solver MSC.Marc. To make analyses faster the substantial parameters are implemented in the algorithm for automatic generation of the bearing calculation (batch file).The theme of this thesis was commissioned by ZKL - Research and development, a. s.

The assembly gap influence on the stress and strain at the radial ball bearing
Rašovská, Hana ; Prášil, Jiří (referee) ; Vrbka, Jan (advisor)
This master thesis deals with the influence of assembly clearance on strain and stress in the radial ball bearing. The theme of this thesis was commissioned by ZKL - Research and development, a. s. For six different assembly clearances and selected ball bearing was made force-loaded static analysis of global computational models. Subsequently was made a static analysis of local computational models loaded by strain according to the results of global models. The output of analysis of local models was sizes of stress, which led to the analysis of bearing with two other models of material. For the solution of the problem was used pre/post processor Patran and solver MSC.Marc.
