Ltd., Nanjing, 210000, Jiangsu, China Abstract: As one of the widely used mechanical components, roller bearings directly influence the performance of the main machine. Due to the complex contact conditions between the rollers and the races, it is still rather challenging to quantitatively estimate the load-carrying capability of the non-standard bearings. Two commonly used methods, i.e., the analytical or semi-analytical methods and the finite element methods are compared in the present study. By combining the two methods, a computation tool was developed to calculate and optimize the load-carrying capability of roller bearings. A typical type of slew bearing was analyzed and its static loading curve, dynamic loading curve and the bolt loading curves were generated as an example. It was shown that the method is very efficient and reliable. Development and deployment of the software would provide valuable assistance to design and optimize new roller bearings.
