Abstract: For replacing in particular a used main bearing of a wind turbine, a bearing housing is first pulled axially off the main bearing along a rotor shaft, then the used main bearing is divided and disassembled. A new main bearing is assembled around the rotor shaft and the original bearing housing is pushed axially back onto the main bearing. During the replacement of the main bearing, the rotor shaft is supported on a machine carrier by means of a holding device, wherein the holding device is arranged at least partially in the region between a bearing seat and a hub-side end region of the rotor shaft.

Abstract: A device for measuring a thrust load acting on a rotor of a hermetically sealed kneader includes displacement sensors (19) and a load-calculating member. The displacement sensors (19) are configured to measure relative displacement along the axial direction of an outer ring-fixing member (17), which is for fixing the outer ring (16) of one end of a bearing (6), or a casing (18) with respect to an inner ring-fixing member (20), which is for fixing the inner ring (13) of the one end of the bearing (6), or the rotor (5). The load-calculating unit calculates the thrust load acting on the rotor (5) by multiplying the relative displacement measured by the displacement sensors (19) by a conversion coefficient.

Abstract: A bearing assembly includes a housing having an interior cavity, an opening, and an inward facing seal mounting surface. The assembly includes a bearing and a shaft mounted in the bearing for rotation about a central axis. The assembly includes a seal positioned axially between the interior cavity and the exterior of the housing to inhibit contaminants from entering the housing and damaging the bearing. The seal has a bearing side, an opening side, and a gap surface facing a corresponding surface that is either an outward facing surface of the shaft or thee inward facing seal mounting surface of the housing. The gap surface is spaced from the corresponding surface by a clearance gap. The width of the clearance gap increases from the bearing side to the opening side to direct fluid in the clearance gap away from the interior cavity as the shaft rotates.
