“…Although cylindrical roller bearings with ribs can bear axial loads in the same way as tapered roller bearings, there are not as many studies on their performance when axial loads act on them as tapered roller bearings. Stuhler et al 20 investigated the slip behavior for full-complement cylindrical roller bearings subjected to combined radial and axial loads. They also investigated the relationship between the slip and smearing damage of the bearings.…”

Tapered roller bearings are often used to support pinions in gear units of electric trains. On the other hand, recently, the application of cylindrical roller bearings with ribs has also been proposed, in which the internal clearance changes little depending on the operating conditions. This study aims to elucidate the effect of differences in just these two types of pinion bearings on the performance of gear units and thereby verify the applicability of cylindrical roller bearings with ribs to railway gear units. Tapered roller bearings and cylindrical roller bearings with ribs of the same dimensions were subjected to rotational tests in the same gear unit. The results showed that the effects of the atmospheric temperature on the maximum temperature, the maximum rate of temperature rise, and the torque of the bearings were not significantly different between the tapered roller bearings and the cylindrical roller bearings with ribs. As the atmospheric temperature decreases, the maximum temperature decreases, and the maximum rate of temperature rise and the torque increase. On the other hand, the endplay values had a significant effect on these values in the tapered roller bearings, while they had little effect on the cylindrical roller bearings with ribs.

Mechanical system often involves the finite line contact of key components such as rolling element bearings and gear pairs. Different contact models have been developed to predict the load-displacement relationship and contact pressure distribution, but there usually exists a trade-off between the accuracy of simulation results and computational cost. An improved slicing technique is presented in this work. According to the half-space theory, a tri-linear fitting model is developed to express the load-displacement relationship and coupling behavior in slices of contact region, which is originally controlled by a spatial convolution. The improved slicing technique is thus formulated based on the tri-linear model. A modified Newton-Raphson algorithm is adopted to solve the free boundary problem of the improved slicing technique. The improved slicing technique is validated to be able to correctly predict the load-displacement relationships and the contact pressure distributions of different contact profiles, especially for contact pressure concentrations which other slicing techniques are unable to predict accurately. The computation speed of the proposed method is much faster than the semi-analytical method and is of the same order of other slicing technique. The high accuracy and low computational cost enable the proposed method to be applied in the on-line calculation of rolling element bearings and other sophisticated mechanical systems.
