Radial Ball Bearings with Angular Contact in Machine Tools

Vibrational Analysis of a Ball Bearing

The project presents an analysis of the vibrational behavior of a deep groove ball bearing with a structurally integrated force sensor. The miniaturized force sensor, accommodated within a slot on the bearings outer ring, provides online condition monitoring capability to the bearing. Analytical and finite element models are developed to predict the sensor output due to bearing dynamic load and...

Test Analysis of Friction Moment between Ball and Cage of Miniature Bearing at Very Low Speed

In some applications, especially for the attitude control of navigation system, the friction moment of instrument ball bearings is one of the much more important factors. Its magnitude and fluctuation affect not only the energy transfer but also the accuracy of signal transfer even though the bearings work at very low speed. Experimental analysis showed that the cage rotated with a minor fluctu...

Film Stiffness Analysis for Angular Contact Ball Bearings Considering Thermal Effect

In order to more accurately calculate the film stiffness of angular contact ball bearing, it is necessary to establish the film stiffness calculation model that is consistent with reality. The frictional heat exists in high-speed ball bearings, and can impact on oil film thickness and stiffness. The calculation model of film stiffness of an angular contact ball bearing taking account of the eff...

Dynamic Behaviour of Ball Bearing Applications with Constrained Damping Layers

Rolling bearing noise has become an aspect of increasing importance for the performance of rotating machinery, like electric motors and gearboxes. Generally, two aspects are important with regard to bearing noise, i.e. the transmission characteristics and the vibration generation characteristics. A potential source of vibrations are for example manufacturing imperfections of the di erent bearin...
