A sealing device comprises a first insert body and a second insert body. The first insert body has an annular first frame, and a first sealing part coupled to the first frame. The second insert body has an annular second frame having a diameter smaller than that of the first frame, and a second sealing part coupled to the second frame. The second insert body rotates relative to the first insert body. The first insert body and the second insert body are arranged such that a gap is formed between the first sealing part and the second sealing part. The second sealing part has a first surface facing the first sealing part and spaced apart from the second frame in a first axial direction; and a first baffle protruding toward the first sealing part from the end of the first surface in the outer radial direction thereof.

A bearing unit having a radially outer ring which is stationary, a radially inner ring, rotatable around a central rotation axis (X) of the bearing unit, provided, in an end portion thereof, with at least two segments of circular sectors separated by at least two grooves, a row of rolling elements interposed between the radially outer ring and the radially inner ring, and a collar for clamping the radially inner ring on to a shaft; each circular sector segment is provided with a lip having a thickness (s) and a step having a thickness (s+s1), wherein the thickness (s+s1) of the step is greater than the thickness (s) of the lip.

A rolling bearing capable of achieving reduction in torque is provided. The rolling bearing includes an inner ring and an outer ring disposed coaxially with each other, a rolling element disposed between the inner ring and the outer ring, a seal member configured to cover an area between the inner ring and the outer ring from an outside in an axial direction, and filled grease disposed between the rolling element and the seal member. The filled grease includes a first ring-like part which extends to form a circumferential shape centering on a common axis of the inner ring and the outer ring, and which has contact with one of the inner ring and the outer ring, and a second ring-like part which extends to form a circumferential shape centering on the common axis, which is connected to the first ring-like part at an outer side in the axial direction, and which has contact with the seal member.

Provided is a seal for a bearing arrangement for sealing an interior space between at least two parts of the bearing arrangement rotatable relatively to each other, and in which the interior space contains a lubricant, whereby the seal includes a seal part which is shaped for conveying the lubricant with a direction component pointing into the interior space.

A drive train for an electric machine is provided. The drive train includes a shaft. The shaft has a front end and a rear end and which is supported in a housing via a front bearing and a rear bearing, wherein the front bearing including a front bearing outer ring and a front bearing inner ring, and the rear bearing including a rear bearing outer ring and a rear bearing inner ring). The drive train includes a first cover mounted to the housing and being configured to seal a rear side of the front bearing, wherein the first cover is mounted to the housing by an auxiliary support which connects the first cover to the housing, a second cover mounted to the housing and being configured to seal a front side of the rear bearing, a third cover mounted to the housing and being configured to seal the rear bearing.

A support structure associated with a nacelle of a wind turbine, wherein the support structure includes a bearing having an outer ring and an inner ring is provided. The bearing is surrounded by a bearing housing and a bearing cover. The bearing cover is coupled to the bearing magnetically. In some embodiments, the bearing cover may be coupled to the outer ring of the bearing by bolting. The thickness of the outer ring of the bearing may be increased to accommodate one or more protrusions. The protrusions are composed of a magnetic material and configured to receive a bearing cover.

One embodiment is a bearing carrier assembly including a circular shield having top and bottom surfaces; and a number of bearing separators integrated with the bottom surface of the shield, wherein each pair of bearing separators defines a receptacle for receiving and retaining a bearing therewithin and wherein the shield blocks the received bearings from debris and retains lubricant around the received bearings. Each of the bearing separators may include a spacer element for separating adjacent ones of the bearings. The bearing carrier assembly may be made up of a number of carrier sections that interconnect to form the bearing carrier assembly.

A wheel case for a vibrating device for vibrating aggregate material includes a housing configured to contain a quantity of lubricating oil and a wheel positioned in the housing and mounted to a shaft of the vibrating device. The wheel includes: an inwardly facing side; an outwardly facing side; an eccentric weight mounted to the inwardly facing side or the outwardly facing side; and a plurality of bearings positioned in an annular bearing channel configured to permit the wheel to rotate about a spindle of the shaft. The wheel case also includes a dam mounted to the wheel at least partially covering the annular bearing channel, positioned such that the lubricating oil collects in the annular bearing channel during rotation of the wheel, and such that the collected lubricating oil remains in the annular bearing channel when rotation of the wheel ceases.

A sealing device comprises a first insert body and a second insert body. The first insert body has an annular first frame, and a first sealing part coupled to the first frame. The second insert body has an annular second frame having a diameter smaller than that of the first frame, and a second sealing part coupled to the second frame. The second insert body rotates relative to the first insert body. The first insert body and the second insert body are arranged such that a gap is formed between the first sealing part and the second sealing part. The second sealing part has a first surface facing the first sealing part and spaced apart from the second frame in a first axial direction; and a first baffle protruding toward the first sealing part from the end of the first surface in the outer radial direction thereof.
