    摘要: In a non-machining method for manufacturing a solid-bottomed or internally flanged bearing race, especially for rolling contact bearings, the starting material is in the form of a band. For the economical manufacture of this bearing race with an annular groove of extremely precise cross-sectional shape which reduces the wall thickness of the bearing race, and which is situated at the transition from the bottom or flange portion to the race portion, a flat roundel is first stamped from the band. Then a concentric annular groove is worked into one of the planar surfaces of the roundel, while the opposite planar surface thereof is supported on a planar supporting surface. Lastly, the roundel is deep-drawn in a die to form a bearing race having a solid bottom. The end face of the drawing punch concentrically engages the roundel's planar surface that is encompassed by the annular groove. This end face has a diameter that is equal to or greater than the diameter of the radially inner edge of the annular grooves and smaller than the diameter of the radially outer edge of the annular groove.

    摘要: The present invention is a device for securing a shaft or the like in a hub, wherein an annular groove is provided on the shaft or in the hub to accommodate an elastic securing ring of round cross-section. A shoulder is provided on the hub or shaft radially facing the annular groove and the hub or shaft has an adjusting member displaceable in axial direction with a conical face axially facing the shoulder. This face together with the shoulder forms an annular recess widening towards the opening of the groove. The floor of the annular groove on the side of the adjusting member is at a radial distance from the shaft or hub at least as great as the thickness of the securing ring.

    摘要: A sliding seal ring for a drill bit comprising at least one cutter rotatably mounted on a journal forming part of the drill bit body. The seal ring is made of elastic metallic strip material and is of spiral configuration with the spirals in overlapping relation. The seal ring is mounted under axial tension between the pocket in an edge ring and the drill bit body and rotates with the cutter. In one form of the invention, the spirals are in abutting relation to provide a complete seal. In another form the spirals are open to define gaps permitting flow of flushing liquid to cool and lubricate the bearings supporting the cutter on the trunnion.
