摘要： A cage segment is for a rolling-element bearing cage, particularly for large rolling-element bearings. The cage segment includes a first side element and a second side element that are connected by a first bridge and a second bridge. At least one pocket is formed between the first and second bridges which is suitable for receiving at least one rolling element. The cage segment is manufactured from sheet metal.

摘要： A spacer includes opposite first and second portions facing one another, and at least two spaced reinforcing beams connected to the first and second portions and extending transversally with respect to the portions, the reinforcing beams being disposed both on one side of the first and second portions. The spacer further includes at least one abutting beam connected to the first and second portions, extending transversally with respect to the portions and located on the side opposite to the reinforcing beams. The first and second portions delimit together with the reinforcing and abutting beams a pocket configured to receive at least a contact roller.

摘要： A roller bearing comprises an outer ring, an inner ring, a plurality of rollers arranged between said outer ring and said inner ring; and a plurality of retainer segments having a plurality of column parts extending in a direction along a shaft so as to form a pocket for holding said roller. A connection part extends in a circumferential direction so as to connect the plurality of column parts, and continuously lined with each other in the circumferential direction between said outer ring and said inner ring, in which a corner of a circumferential end face is chamfered. Also provided is a spacer arranged between the circumferentially arranged first retainer segment and last retainer segment, wherein a chamfered part is provided at a corner of a circumferential spacer end face of the space. The roller bearing can be used in a main shaft support structure of a wind-power generator.

摘要： A split bearing cage for a rolling-element bearing assembly includes a first bearing cage segment and a second bearing cage segment each having two side ring sections axially spaced apart by a plurality of bridges. Adjacent pairs of the bridges define rolling-element receiving pockets for receiving rolling elements of the rolling-element bearing assembly and for holding the rolling elements spaced apart from each other and for guiding the rolling elements. The first bearing cage segment is connected to the second bearing cage segment via a swivel joint that may be formed of a bolt element on a first end of the first bearing cage segment and an at least partial eyelet on the first end of the second bearing cage segment.

摘要： A cage of a cage and rollers includes engaging projecting portions that are provided on outer circumferential surfaces of rim portions, the engaging projecting portions being configured to be elastically deformed when the cage is inserted into a support hole of a rocker arm to thereby allow the cage to be contracted in diameter and to be elastically restored to be brought into engagement with the rocker arm after the cage is inserted in the support hole, to thereby position the cage properly in relation to an axial direction relative to the rocker arm. The cage and rollers can be assembled to the rocker arm while being positioned properly in relation to the axial direction so that the cage and rollers and the rocker arm can be formed into a rocker arm unit, and the cage and rollers can easily be assembled to the rocker arm.

摘要： 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.

摘要： 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.

摘要： A roller bearing comprises an outer ring, an inner ring, a plurality of rollers arranged between the outer ring and the inner ring, and a plurality of retainer segments having a plurality of column parts extending in a direction along a shaft so as to form a pocket for holding the roller, and connection parts and extending in a circumferential direction to connect the plurality of column parts, and continuously lined with each other in the circumferential direction between the outer ring and the inner ring. The column part is positioned at an circumferential end of the retainer segment. Here, a circumferential outer side end face of the column part positioned at the end is flat, and a circumferential inner side end face of the column part positioned at said end is provided with a recess recessed in the circumferential direction to reduce the thickness of the column part.
