A sealing device employing a magnetic fluid for sealing off a vacuum side and an atmosphere side includes two rolling bearings disposed on both sides of the magnetic fluid seal. The magnetic fluid fills the lubrication part of the rolling bearing disposed toward the vacuum side and a magnet is attached to the outer ring toward the vacuum side of said rolling bearing. A ring-shaped yoke formed from a magnetic material and freely fitting into a rotation shaft is attached to the side of the magnet opposite the outer ring of the rolling bearing.

The present disclosure discloses a magnetic liquid sealing device adapted to axial and radial displacements of connection, which includes: an end cover; a rubber-sealing-ring equipped first clamping plate fixed on the end cover by a first screw and a second screw; a rubber-sealing-ring equipped second clamping plate installed in a groove of the end cover; a fundamental sealing structure fixed on the rubber-sealing-ring equipped second clamping plate by a third screw and a fourth screw, so as to be isolated from the end cover by the rubber-sealing-ring equipped first clamping plate and the rubber-sealing-ring equipped second clamping plate. The device isolates the connected component from the magnetic liquid sealing structure by the two clamping plates, such that the axial and radial deformations and displacements of the connected component will not be loaded on parts in magnetic liquid sealing structure, prolonging the service life of the magnetic liquid sealing.

A drive module (1, 1a) includes an axle casing (2) and a shaft (3) rotatably mounted in an interior space (11) of the axle casing (2). Two bearing units (6, 6a) lie opposite each other and are secured in the axle casing (2) in an axial direction. Each bearing unit (6, 6a) includes an inner bearing ring (7, 7a) fixedly connected to the shaft (3), an outer bearing ring (8, 8a) fixedly connected to the axle casing (2), and rolling elements (9, 9a) arranged between the inner bearing ring (7, 7a) and the outer bearing ring (8, 8a). A lubricating fluid is present at least in the interior space (11). The lubricating fluid forming a fluid reservoir at a bottom of the interior space (11). The axle casing (2) includes a fluid opening extending, in each case, from the interior space (11) to a respective bearing unit (6, 6a) for conducting the lubricating fluid to the rolling elements (9, 9a). At least one conduction device is fluidically connected to the fluid reservoir and is configured for conducting the lubricating fluid the interior space (11) to the respective fluid opening.

An object of the present invention is to provide a fishing reel wherein a bearing rotatably supporting a drive shaft securely shuts out water from its interior so as to maintain stable sealing and thus smooth rotation for a long period wherein such a bearing can be readily built in. In accordance with one aspect, the fishing reel of the present invention includes a drive shaft to be rotationally driven for winding a fishing line around a spool. The drive shaft is rotationally supported by a magnetic fluid sealed bearing having an inner ring magnetic fluid retained between an inner ring and a polar plate retaining a magnet and/or between the inner ring and the magnet, and an outer ring magnetic fluid retained between an outer ring and the polar plate retaining the magnet and/or between the outer ring and the magnet.

Systems, devices, uses and methods relating to magnetorhological materials including carbon nanotubes, such as single-walled and multi-walled carbon nanotubes, are disclosed. Uses of magnetorheological materials such as in motion damping/vibration isolation are also disclosed.
