Abstract
Abstract In a radial bearing suitable for use with a machine shaft having an adjustable support structure which can compensate for undesirable operational forces, a bearing housing surrounds upper and lower bearing sleeves in which the lower sleeve and an adjustment member are positioned in a hemispherical bearing support. In turn, this support rests on the bottom plate of a bearing support block. Adjustment of the bearing sleeves is effected by having a space intermediate the bottom plate and the hemispherical bearing support continuously lubricated via a high pressure lubricating system. Additional lubricating medium in the gap between the shaft and bearing sleeves, serves to provide lubrication to the bearing support, as operational speed is attained and the high pressure oil system is turned off.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
106 words
Radial bearing for machine shafts comprising a bearing housing disposed about a shaft; bearing sleeve means having upper and lower sections, respectively, disposed within said bearing housing, said lower section being seated in place by a separate hemispherical bearing support; bearing block means; a ball-cuplike recess provided in said bearing block means adapted to seat said hemispherical bearing support; and means intermediate said hemispherical bearing support and said bearing block means for providing a lubricating medium therebetween, including adjustment means disposed intermediate said lower section and said bearing support, said adjustment means having a generally U-Shaped configuration and being adapted to cooperate with said lower section.
Claim 2
Dependent Claim
106 words
Radial bearing for machine shafts comprising a bearing housing disposed about a shaft; bearing sleeve means having upper and lower sections, respectively, disposed within said bearing housing, said lower section being seated in place by a separate hemispherical bearing support; bearing block means; a ball-cuplike recess provided in said bearing block means adapted to seat said hemispherical bearing support; and means intermediate said hemispherical bearing support and said bearing block means for providing a lubricating medium therebetween, including adjustment means disposed intermediate said lower section and said bearing support, said adjustment means having a generally U-Shaped configuration and being adapted to cooperate with said lower section.
Claim 3
Dependent Claim
27 words
Radial bearing as claimed in claim 1, wherein said adjustment means are provided with longitudinally extending members which cooperate with lateral recess means in said lower section.
Claim 4
Dependent Claim
27 words
Radial bearing as claimed in claim 1, wherein the top surface of said hemispherical bearing support includes a cylindrically shaped recess adapted to receive said lower section.
Claim 5
Dependent Claim
27 words
Radial bearing as claimed in claim 1 wherein the top surface of said hemispherical bearing support includes a cylindrically shaped recess adapted to receive said adjustment means.
Claim 6
Dependent Claim
24 words
Radial bearing as claimed in claim 1, including shims disposed between said lower section and said adjustment means for adjusting said bearing sleeve means.
Claim 7
Dependent Claim
38 words
Radial bearing as claimed in claim 1, wherein fitting members having spherical contact surfaces are disposed between said upper and lower sections of said bearing sleeve means and are adapted to permit adjustment with respect to said shaft.
Claim 8
Dependent Claim
80 words
Radial bearing for machine shafts comprising a bearing housing disposed about the shaft as well as a sleeve divided in a horizontal plane, into upper and lower bearing sleeves, the lower bearing sleeve being supported by a separate bearing support the underside of which is shaped hemispherically with a smaller radius of curvature than that of the bearing sleeve, a bearing block, said bearing support being disposed in a corresponding ball-cup shaped recess of said bearing block under liquid friction.
Claim 9
Dependent Claim
80 words
Radial bearing for machine shafts comprising a bearing housing disposed about the shaft as well as a sleeve divided in a horizontal plane, into upper and lower bearing sleeves, the lower bearing sleeve being supported by a separate bearing support the underside of which is shaped hemispherically with a smaller radius of curvature than that of the bearing sleeve, a bearing block, said bearing support being disposed in a corresponding ball-cup shaped recess of said bearing block under liquid friction.
