ABSTRACT:
This patent relates to pillow blocks, which are constructed to include one or more roller bearings disposed in tangential relation to the primary shaft at one or more positions around its periphery. Each roller bearing is mounted to rotate about its own stud, so that it acts as a cam follower. In some embodiments the roller bearings are disposed singly, or in pairs, in three positions spaced-apart 120 degrees around the periphery of the shaft. A particular feature of the invention is a device for fine tuning the tangential contact between a roller and the surface of the primary shaft by utilizing a flexible bearing support plate supporting at least one bearing. The plate can move radially to control the radial distance of the bearing.
