摘要： A rolling bearing has an inner and an outer bearing ring. Each bearing ring has an inner and an outer shell surface. The roller bearing has rolling elements, which roll on raceways provided on the respective shell surfaces of the bearing rings, and a sealing disc connected to one of the bearing rings and operatively connected in a sealing manner to the other bearing ring. To connect the sealing disc to the bearing ring, one of the shell surfaces of the one bearing ring includes a first connecting means and the sealing disc includes a second connecting means. The first connecting means provide a rotating engagement in which the second connecting means engage in a connected state of the bearing ring and the sealing disc.

摘要： Methods and systems for an axle are described. The axle may be a steering axle that is coupled to wheels that may move to change a steering angle of a vehicle. In one example, the axle includes two bearings that are arranged similarly so as to reduce a height of an axle. The two bearings may be tapered wheel bearings so that vertical and lateral wheel loads may be supported via an actual total of two bearings per wheel.

摘要： In a tapered roller bearing in which a segment holder divided into a plurality of segments in a circumference direction is used in an inner ring assembly, which is incorporated into an outer ring, guide claws are provided on an outer-diameter side of adjacent columnar portions of each pocket of a holder to allow the tapered rollers to be inserted into the pockets from an inner-diameter side of the segments. An engaging portion is provided on a large-diameter-side lateral-surface of a large-diameter-side arc-shaped portion of the segment. A connecting member, which is to be wound around on a large-diameter side of the segments arranged in a ring shape, is made to pass through the engaging portion, and ends of the connecting member are removably connected together by a fastening member, so that adjacent segments are butted together and fixed.

摘要： An axial bearing assembly is provided having a first washer forming a first raceway and including a radially inner retention flange, and a second washer forming a second raceway axially spaced apart from the first raceway, with the second washer including a radially outer retention flange. A cage including a radially inner rim, a radially outer rim, and a plurality of segments extending between the radially inner and outer rims defining a plurality of rolling element pockets is located between the first and second raceways. Rolling elements are located in at least some of the pockets. The radially outer rim of the cage includes a circumferentially extending groove on a radially outer surface. Outer retention tabs extend from the radially outer retention flange into the circumferentially extending groove.

摘要： A roller for a control surface of an aircraft includes a roller shaft, a primary roller coupled to the shaft, and a roller assembly coupled to the shaft. The shaft includes a longitudinal axis, a mounting end that couples with a roller fitting of the control surface, and a roller end. The primary roller can rotate about the longitudinal axis, and can engage and roll along a first surface of a track. The roller assembly includes a secondary roller having a longitudinal roller axis and configured to engage and roll along a second surface of the track. The roller assembly also includes a housing that retains the secondary roller while allowing the secondary roller to rotate about the longitudinal roller axis. The housing is movably coupled to the roller end of the roller shaft with three degrees of rotational freedom relative to the roller end of the roller shaft.

摘要： A rolling bearing having concentric bearing rings supported on one another rotatably with respect to each other by means of at least one row of rolling elements and have bearing races for the rolling elements of the at least one row of rolling elements. The invention further relates to a material transfer- or construction machine, such as a crane or cable excavator, having such a rolling bearing. Providing different bearing race corrections in different angular sectors of the bearing rings and/or providing the bearing race correction only in a fraction of the circumference of the bearing rings is advantageous over the conventional use of a bearing race correction that is constant over the circumference. A bearing race correction that is limited to one sector or that is different from sector to sector, or that is not constant over the circumference, enables the bearing rings to adapt to expected loads.

摘要： A spindle nut retainer is used with a spindle with a flat portion on its threaded end. The flat portion interrupts the threads on the threaded end. A washer with a mating flat portion is slidably mounted over the threaded end and a nut is removably threaded to the threaded end of the spindle against the washer to set the preload on bearings. The nut retainer overlays a plurality of the corners of the nut and engages the threaded portion of the spindle with tangs. A majority of the tangs are flexed or bent to remain in biased contact with the threads on the spindle. Some of the tangs are located over the flat portion and remain unbent. The tangs resist rotation of the nut by engagement with the flat portion where it meets the threads.

摘要： A bearing arrangement for guiding a motor shaft for supporting axial and/or radial forces of a vertical turbine pump. The bearing arrangement includes a bearing comprising an inner ring which can be non-rotatably connected to the motor shaft and an outer ring, an oil sump filled with an oil, within which the bearing is arranged at least partially immersed in the oil, and an inner oil deflector which is non-rotatably connected to the inner ring and deflects oil conveyed between the inner ring and the outer ring back into the oil sump as a result of rotation of the bearing.
