Abstract:
The dynamic characteristics analysis theory is founded and a software is developed with Matlab tool. Taking type 3182120 bearing as an example, the nonlinear relation between the radial stiffness of the bearing and the parameters of the bearing such as the rotational speed, the radial tightening and the radial load is analyzed up to the rotating speed of 15 000 r/min. The results show that the radial stiffness intenerates nonlinearly with the rising of rotating speed owing to the centrifugal force. The radial stiffness increases with the enhancement of radial tightening. Under a certain tightening, the roller will be divorced from the inner ring when the rotating speed reaches a certain value. The effect of radial load to radial stiffness can be neglected. The analysis theory, method and software of dynamic characteristic parameters for the double row cylindrical roller bearing with taper hole provide a powerful tool for the dynamic design of machine tool.
