  • Patent number: 5007746
    Abstract: A thrust bearing is provided with resilient mounting tangs in the form of one or more axially and radially projecting leaf springs. Each leaf spring is shaped with a wedge-like camming surface which facilitates the insertion and centering of each tang within a mounting recess formed in a bearing housing. As the tang is wedged and cammed within its mounting recess, the leaf spring is resiliently deflected and compressed therein to securely anchor the bearing in place.

  • Patent number: 4383719
    Abstract: A journaled bearing assembly including a pair of semicircular half shells defining a sleeve bearing with an outer surface and an inner bearing surface with the surfaces extending axially between laterally spaced opposite ends and circumferentially between oppositely disposed parting faces with the bearing surface being concave and the outer surface being convex axially between the ends while in the free state and held at gage diameter. In the free state the terminal portions adjacent the parting faces are on a longer radius than the radius of the central portion. When held at gage diameter the terminal portions are on a radius equal to the radius of the central portion. The bearing sleeve is disposed in a bearing housing with the bearing surfaces in engagement with a journaled portion of a shaft. The bearing housing includes clamping members in clamping engagement with the outer surfaces of the half shells to apply radical forces to the half shells.
