Abstract:

This paper presents a new method, called data fitting method based on numerical results, to calculate the contact deformation between logarithmical crowned roller and raceway of rolling bearings. First, the contact deformations between logarithmically crowned roller and raceway are analyzed and numerically calculated according to influence coefficient method, and then a fitting formula based on the calculated contact deformations is obtained by means of multiple linear regression method. The formula includes the dimensions and logarithmic crowned parameters of bearing together with the load parameter, and can be used for fast calculation of contact deformation between logarithmical crowned roller and raceway in low and medium load conditions, so that the formula is suitable to efficiently analyze the dynamics characteristics of arbitrary logarithmic crowned rolling bearing.
