Bearing cage segment, antifriction bearing, and assembly method
A bearing cage segment for a rolling-element bearing includes at least one sliding surface on which a surface of at least one rolling element of the rolling-element bearing is rotatable, a first support element, such as an axial projection on an axial side of the cage segment having a radially open radially facing channel, at a first radial position for supporting a first band section of a band clamp during an assembling of the rolling-element bearing, and at least one second support element at a second radial position different from the first radial position for supporting a second band section of the band clamp.
MILKING PLATFORM
A rotary milking platform 1 has a deck 2, a circular upper beam 4 connected to and supporting the deck, a circular lower beam 6 and a series of carriages 5 connected end to end to form a ring between the beams. The platform is formed such that the upper beam 4 is arranged to rest and rotate on the ring of carriages 5 to rotate the deck 2. Each carriage has at least one carriage roller 10, and each roller 10 arranged to rotate on the lower beam 4. Each roller 10 also has a retention flange 11 at only one side. The flanges 11 of some of the rollers 10 are at or adjacent an inner side of the ring, and the flanges 11 of others of the rollers are at or adjacent an outer side of the ring. The rollers 10 of the ring are arranged such that at least one roller is oriented with its flange 11 on an opposite side to another of the flanged rollers immediately adjacent to it. The flanges prevent the carriages from moving off the lower beam 4 when the platform 1 is in use. Further, at least some of the carriages can be disconnected from the ring and swung laterally to be moved free of the beams 4, 6 for maintenance, repair or replacement.
Cage segment, segmented cage, and bearing
A cage segment for a bearing rotatable around an axis of symmetry that defines an axial direction and able to receive a plurality of rolling elements and having an inner and outer walls that extend circumferentially in the form of a of cylinder. A plurality of radial beams extend globally radially with respect to the axis and connecting the inner and outer walls. Each axial radial beam having a central portion and two end portions that are opposite with respect to the central portion. The central portion being symmetrical with respect to a plane of symmetry. The plane of symmetry of the at least one end portion cooperating with a rolling element to center the segment, forms with the plane of symmetry of the central portion an angle which is not equal to zero.
Cage
A cage of a roller bearing includes at least two cage segments, wherein each cage segment is formed from two side pieces, which are disposed at an axial distance from one another, and from a plurality of webs that are circumferentially distanced from each other and that connect the side pieces in the axial direction, wherein each cage segment forms an arc of a given arc length, the plurality of webs includes a center web, which maintains a distance of half the given arc length from the circumferential ends of the respective cage segment, and wherein the center web is penetrated by a bore the center axis of which approximately runs through the center of gravity of the cage segment, and which is configured to accommodate a radially outwardly directed moving device in a releasable manner.
CAGE SEGMENT, SEGMENTED CAGE, AND BEARING
A cage segment for a bearing rotatable around an axis of symmetry that defines an axial direction and able to receive a plurality of rolling elements and having an inner and outer walls that extend circumferentially in the form of a of cylinder. A plurality of radial beams extend globally radially with respect to the axis and connecting the inner and outer walls. Each axial radial beam having a central portion and two end portions that are opposite with respect to the central portion. The central portion being symmetrical with respect to a plane of symmetry. The plane of symmetry of the at least one end portion cooperating with a rolling element to center the segment, forms with the plane of symmetry of the central portion an angle which is not equal to zero.
Rolling-element bearing
A rolling bearing includes an inner ring, an outer ring, a plurality of rolling elements disposed between the inner ring and the outer ring, and a plurality of cage segments separating circumferentially adjacent ones of the plurality of rolling elements. Each of the cage segments has an axial bridge portion and side plates at axially opposite ends of the bridge portion, each of the side plates having a convex end and a concave end circumferentially spaced from the convex end. The convex end of a first one of the side plates contacts the concave end of a second one of the side plates.
ROLLING-ELEMENT BEARING
A rolling bearing includes an inner ring, an outer ring, a plurality of rolling elements disposed between the inner ring and the outer ring, and a plurality of cage segments separating circumferentially adjacent ones of the plurality of rolling elements. Each of the cage segments has an axial bridge portion and side plates at axially opposite ends of the bridge portion, each of the side plates having a convex end and a concave end circumferentially spaced from the convex end. The convex end of a first one of the side plates contacts the concave end of a second one of the side plates.
