Cageless, Multilayered, Full Complement Axial Tapered Roller Bearing · 模型 170922
Third of several different rolling element bearing concepts I came up with back in late 2013 – early 2014. Unlike the first and second designs, this one is an axial bearing, meant to primarily support axial loads. However, it likewise features the unique trait of employing 3 stacked layers of intermeshing interspersed rolling elements rather than just one. But these are now tapered cylinders rather than uniform cylinders or spheres and are arranged in a radial pattern converging on the bearing's axis of rotation rather than being arrayed parallel to it. As with the other two bearing concepts, the middle layer of rollers serves as a sort of rolling, load bearing cage keeping consecutive rolling elements in each of the other two rows from coming into contact with one another (while its own consecutive rollers are, in turn, likewise being kept separated by those in the other two rows). The middle layer of elements also conveys load between the other two as well, as in the other two designs. It's necessary for the rollers to be tapered because, due to their arrangement, they need to roll in a circle around the bearing's centre while pointing to it rather than in a straight line, always parallel to the bearing's axis of rotation and never pointing to it, as in the radial roller bearing concept. As such, the end of each roller which faces the centre of the bearing needs to have a diameter which is proportionally smaller than its opposite end, which is facing away. So that it naturally wants to roll in a circle rather than in a straight line. As with the first bearing concept, the bearing should inherently automatically adjust for slight differences (owing to manufacturing tolerances) in the respective diameters of its various rolling elements. It should also inherently automatically spread the axial load evenly across all of its rollers. If rollers in the top and bottom layers in a particular sector of the bearing are experiencing higher load than elsewhere or than the average over all of the bearing's rolling elements then they get pushed down (and closer together) in that area. In the process, they also cause rollers in the middle layer to get pushed out sideways and closer together elsewhere in the bearing. Which, in turn, causes corresponding rollers in the top and bottom layers elsewhere in the bearing to get spread apart away from each other and get pushed up against the bearing's axial load, of which they consequently pick up a larger propo...
