A lock for use with an assembly is provided. The assembly includes an inner race having a bore with a generally tapered periphery. The bearing assembly supports a shaft. The bearing lock includes a sleeve having a generally cylindrical internal periphery adapted for cooperation with the shaft and a generally tapered external periphery that cooperates with the bore. The sleeve conforms from a first condition whereby the internal periphery defines a first diameter to a second condition whereby the internal periphery defines a second diameter different than the first. The bearing lock also includes a collar that cooperates with the sleeve to urge the sleeve from the first condition to the second condition. The collar conforms from a first condition whereby the generally cylindrical internal periphery defines a first diameter to a second condition whereby the internal periphery defines a second diameter substantially different than the first.

A driving force transmission mechanism includes a worm gear unit as a brake disposed between a driving motor and an electrically driven input gear, and is configured such that when a driving force is applied from the driving motor to the electrically driven input gear through the worm gear unit, an outer ring which rotates together with the electrically driven input gear becomes locked to an inner ring through rollers so that the driving force is transmitted to an output gear, which rotates together with the inner ring, and when a driving force is applied to a manually driven input shaft, the outer ring and the inner ring are unlocked from each other by an unlocking piece which rotates together with the manually driven input shaft, and thereafter, the driving force is transmitted to the inner ring and the output shaft.

A viscous clutch includes a housing, an input device rotationally fixed to the housing, a rotor, a working chamber, a reservoir, a valve, and a quick disconnect bushing. The housing has a base, a cover, and a housing hub connected in in a rotationally fixed configuration. The input device is a pulley, a sprocket, and/or a gear. The rotor has a rotor disk and a rotor hub connected in a rotationally fixed configuration, and a central opening extends entirely through the rotor hub. The reservoir is carried by the housing and overlaps the input device in an axial direction. The quick disconnect bushing is removably secured to the rotor hub at the central opening and permits a rotationally fixed engagement between the rotor and an item driven by the clutch, such as an output shaft.

A linear actuation screw having a first end portion, a second end portion on an opposite side as the first end portion, and a sloping intermediate portion between the first end portion and second end portion. The first end portion has a threaded outer wall having a generally constant first diameter over at least a portion of its length and is configured to advance a nut or a sliding member along at least a portion of the first end portion. The second end portion has a threaded outer wall having a generally constant second diameter that is different from the first diameter and is configured to receive a motor fastening nut around it in order to secure the linear actuation screw to a motor. The sloping intermediate portion includes an outer wall that is generally smooth and continuous over at least a majority of the area of the outer wall.

The claimed invention concerns a holding device for application of a sealing member (21) on a shaft (23). The holding device (22) includes a connecting mechanism (26, 27) adapted to connect the sealing member (21) on the shaft (23). The connecting mechanism includes an annular body (24) that comprises an inner surface (24a) which, in an axial direction, is arranged at gradually decreasing radial distance from the shaft (23). The connecting mechanism comprises at least a clamping element (26) arranged in a space between the inner surface (24a) of the annular body and the shaft (23), and a displacement mechanism (27) adapted to displace the clamping member in said axial direction relative to the annular body (24) to a position in which the inner surface (24a) of the annular body presses the clamping element to the shaft. The claimed invention also relates to a mechanical sealing device including such a holding device and a hydrodynamic machine having such a mechanical sealing device for applying a sealing member on a shaft.

The present invention relates to a coupling assembly (1) for fixedly connecting a rotational member (2) to an end section (3) of a hollow shaft (4). It may e.g. be used for connecting the main shaft (4) of a wind turbine (28) to a planet carrier (2) of a coaxial planetary gear system. The coupling assembly (1) comprises a shrink ring (6) and a coupling element (7). The shrink ring (6) has an outer diameter corresponding to the inner shaft diameter (d) and a conical surface (14) for connecting the shrink ring (6) and the coupling element (7). The coupling element (7) comprises an annular groove (18) with a groove diameter corresponding to the outer shaft diameter (D) and a conical surface (20) matching the shrink ring (6). When in use, the hollow shaft (4) is arranged in the groove (18) and connected to the coupling element (7) by axially extending bolts (9). Hereby a torque can be transferred by both the shrink connection and the bolts fastened into the hollow shaft. The coupling element (7) preferably comprises an outer flange (26) to which the rotational member (2) can be fastened.
