Roller support video
Rolling bearings, as a basic form of support in building structures, have an ideal force transmission mode that only transfers vertical loads from the upper structure, while releasing horizontal internal forces generated by factors such as temperature changes. The performance of rolling bearings depends on the rolling friction performance of the rollers, and there is currently relatively little research in this area both domestically and internationally. This article focuses on a unidirectional rolling bearing for a certain project, and tests its rolling friction performance under vertical load, lateral horizontal load, and the combined action of vertical load and lateral horizontal load. Through experimental research, the influence laws of vertical pressure on the bottom roller and lateral horizontal pressure on the rolling friction coefficient of the side roller have been mastered. At the same time, the experimental results also indicate that under the combined action of vertical and horizontal loads, the measured frictional force of the bottom roller and side roller working together is slightly greater than the combined frictional force of the bottom roller and side roller working separately. The research results provide a basis for the design of structures with this type of support form
