The radial widths of these two shoulders are both symmetrical about the centerline of the thrust bearing such that on-bottom thrust loads are transferred non-eccentrically to the thrust bearing, thereby avoiding twisting loads on the thrust bearing races, increasing the effective on-bottom load capacity of the thrust bearing and extending its service life.

  • Publication number: 20120213458
    Abstract: The replaceable bearing for a conveyor roller is installed in a bearing housing, which is removably installed within the end of the conveyor roller. The bearing housing threads into a mating insert or sleeve, which is permanently installed within the end of the conveyor roller. Alternatively, the inside of the conveyor roller may be threaded and the bearing housing threaded directly into the conveyor roller, if roller wall thickness is sufficient. The outer face of the housing includes a plurality of notches so that a mating wrench engages the notches to thread the housing and its bearing into or out of the end of the roller. The replaceable bearing allows the bearing and its housing to be replaced while retaining the conveyor roller.

  • Publication number: 20120135812
    Abstract: A shaft support for a first rotating shaft and a second rotating shaft. The shaft support includes a housing, a first bearing, and a second bearing. The housing includes a first portion, a second portion, and a transition portion connecting the first portion and the second portion. The first bearing is coupled to the first portion. The first bearing rotatably supports the first shaft and resists at least a portion of a first radial load exerted on the first shaft. The second bearing is coupled to the second portion and rotatably supports the second shaft. At least a portion of the first radial load is transmitted to the transition portion from the first bearing.

  • Publication number: 20120134609
    Abstract: Disclosed is a coupling structure of a bearing for an EPS motor to eliminate a gap caused by a tolerance between the bearing and a pocket of a housing of the EPS motor, thereby improving assembling precision and reducing noise, the coupling structure supporting rotation of a rotating shaft through the bearing coupled to a lower portion of the housing and including a bearing pocket bent upwards from a lower surface of the housing and having a cylindrical space to support an outer circumference of the bearing at an inner wall thereof, whereby a gap between the inner wall of the bearing pocket and the outer circumference of the bearing is eliminated by deforming the inner wall towards an inner circumference thereof by caulking, coupling force between the bearing and the housing can be increased, and thereby reliability in assembly and operation of the motor is improved.

  • Publication number: 20120128279
    Abstract: A method for assembling a set of bearing assemblies 100 onto a mill roll 10 and for establishing a required bearing setting. The mill roll 10 is configured to receive a set of bearing assemblies 100 at each axial end, with the bearing rolling elements 100A contained within supporting chocks 102 adapted for placement within a mill housing. The chock assembly 102R and bearing assembly 100 at a first end of the roll are positioned first, and coupled to the first end an axial center rod 22 passing through an axial bore 24 of the roll 12. The chock assembly 102L and bearing assembly 100 at the second end of the roll 12 is then positioned onto the opposite end of the roll 12, and a connecting sub-assembly 300, 400, 504A is secured to the second end of the axial center rod 22. The connecting sub-assembly engages the second chock assembly 102L and bearing assembly 100, and is adjusted to achieve a desired bearing setting for both bearing assemblies 100 through the center rod 22.
