Internal Geometry Optimization of Angular Contact Ball Bearings
Journal Title: Machine Design - Year 2017, Vol 9, Issue 4
Abstract
Globally is known that cutting machine tools are challenged with increasing the performances as well as productivity, accuracy, product quality. All of these challenges are depend of various criteria, as is spindle set stiffness. Behavior of this assembly beside the main spindle, is very affected by ball bearing characteristic, as are ball bearing stiffness and dynamic capacity. Consequences of insufficient these two characteristic are not only inaccurate parts, but as well decreasing estimated lifetime of rolling bearings and vibration problem. Agricultural engineering involves a wide range of machines, equipment and implements. This ranges from tillage machines, tractors, tedders and balers to powerful harvesting equipment such as forage harvesters or combine harvesters. Even if the machines are very different, the operating conditions are always harsh. For the past several decades, significant efforts have been devoted to modeling and analysis of rolling-element bearings to aid in their design and application. [1] Commercial computational software with ability in field of finite element analysis and optimization has been used in order to obtain analysis how radius value of inner and outer groove affects to ball bearing behavior. Results from numerical study demonstrate that variation of both groove radius and their ratio has considerable effect to stiffness and dynamic capacity. Therefore, optimizing the values of groove radius can improve rolling bearing behavior.
