Abstract:

：Aiming to rotational accuracy of cylindrical roller bearing, the radial runout of outer ring of assembled bearing is studied by numerical computation, and form error of outer ring raceway is experimentally investigated. According to the motion and geometric relationships among bearing components, a mathematical model for cylindrical roller bearing is developed to investigate the influence of roundness error (i.e., amplitude, order) of outer ring raceway, the number of roller and radial clearance on rotational accuracy of cylindrical roller bearing. The model is validated to be reasonable by theory calculation results. The results indicate that the roundness error of outer ring raceway has a significant impact on rotational accuracy of cylindrical roller bearing. When the roundness error order and number of roller satisfy certain conditions, the rotational accuracy of cylindrical roller bearing significantly decreases. When the surface waveform of outer ring raceway changes sharply, the influence of the number of roller on rotational accuracy of cylindrical roller bearing is obvious. The roundness error of outer ring raceway is experimentally investigated. The results show that the roundness error of outer ring raceway is subject to normal distribution. Amplitude and order of roundness error change exponentially. The function relation between the radial runout of outer ring and harmonic distribution parameters of outer ring raceway is obtained. This function relation is used to predict the radial runout of outer ring.
