摘要： A seal assembly for sealing a space between a housing and a component against a liquid medium includes a seal element fixedly connectable to the housing, the seal element including a seal lip that is movable at least in a radial direction, the seal lip being disposed at an angle with respect to the radial direction and a support element in abutment with the seal lip. The support element and the seal element are configured such that a pressure exerted on the seal lip by the liquid medium is transmittable in the radial direction to the support element, and the seal assembly also includes a further seal assembly on a side of the support element axially opposite the seal element, the further seal assembly including a first seal having a first seal body and a second seal having a second seal body.

摘要： A rolling element bearing having a first ring element, a second ring element (3), a plurality of rolling elements arranged in a space between the first and the second ring elements such that the first and the second ring elements can rotate relative each other around a rotational axle. The bearing further includes a sealing ring for sealing off a circumferential opening of the space between the first and the second ring element. The sealing ring is connected to the first ring element and further arranged to rotate relative the second ring element of the rolling element bearing. The sealing ring provides a power generating system that provides at least one pick-up element arranged to generate electrical power when the rolling element bearing rotates. The power generating system is located completely within the circumferential opening of the space.

摘要： A bearing ring having an elongated sensor element that runs along at least a part of a surface of the bearing ring. The connection between the sensor element and the bearing ring is established by a metallic metal material connected by material bonding with the bearing ring as well as with the sensor element. To improve the life of the bearing a sensor element is arranged in a groove that is machined in the bearing ring. The groove extends from the surface of the bearing ring. The metallic material includes or is connected with a flat metallic strip. The flat metallic strip is arranged at or in the surface of the bearing ring and covers the groove.

摘要： The invention relates to a cover device for at least sectional closing of an underwater opening in a hull of a watercraft, in particular an opening of a transverse channel of a thruster. According to the invention the cover device includes at least one variable-volume hollow chamber lip including at least one buoyancy body, and the at least one hollow chamber lip is shiftable into an expansion state or into a shrinkage state by supplying or removing a fluid, in particular air. As a result of the variable-volume or inflatable cover device a more reliable and simultaneously lower-maintenance operation of the cover device is given. In addition, the invention has a thruster, in particular a bow or stern-thruster, as subject matter.

摘要： The present invention defines a method of determining a vertical profile signal of a rail surface that includes, obtaining a vertical acceleration signal acc1, by measuring vertical acceleration of a bogie of a rail vehicle that runs on the rail surface; processing the vertical acceleration signal to obtain a vertical velocity signal; determining the vertical profile signal of the rail surface, by using the vertical acceleration signal and the vertical velocity signal as inputs to a simulation model of the bogie, the model having an unsprung mass connected to a sprung mass, the vertical acceleration signal acc1 represents the vertical acceleration of the unsprung mass; and measuring a linear velocity signal of the rail vehicle, the linear velocity signal is used in the step of determining to convert the vertical profile signal from the time domain to the distance domain.

摘要： A self-aligning roller bearing having inner and outer bearing ring elements and at least one row of roller elements disposed in between. The inner bearing ring element having a retaining flange provided on a first axial side of the roller bearing being configured for preventing the roller elements from falling out from the roller bearing. The roller bearing having a first sealing ring element located at the first axial side for sealing the first axial opening, the first sealing ring being rotatable in relation to the inner bearing ring and seals against a sealing mating surface of the inner bearing ring. The retaining flange has at least one filling slot configured for allowing the roller elements to be inserted in-between the inner and the outer bearing ring elements during assembly of the roller bearing, and the sealing mating surface being axially outside the at least one filling slot.

摘要： A railcar adapter for connecting a railcar body to a bearing is provided. The railcar adapter includes an adapter body having two lateral channels each delimited by a pair of opposed lugs adapted to cooperate with the railcar body, an inner surface acting as a bearing seat for the bearing and an outer surface in radial contact with the railcar body. The inner surface includes at least one central groove located on a first axis of symmetry of the railcar adapter emerging in each lateral channel. The inner surface further provides a second central groove located on a second symmetry axis of the railcar adapter, perpendicular to the first symmetry axis.
