Bearing unit manufacturing device and bearing unit manufacturing method
A manufacturing device manufactures a bearing unit including an inner ring member outwardly fitted onto an end portion of a shaft main body of an inner shaft on one side in an axial direction and fixed by a swaged portion extending from the end portion. The manufacturing device includes: a rotating mechanism including a rotor which holds the other side of the inner shaft in the axial direction from below and rotates the inner shaft about a center axis of the inner shaft while the center axis is aligned with an up-down direction, the rotor being mounted below a processing area of the bearing unit; and a swaging mechanism mounted above the processing area and including a punch which is brought into contact with the swaged portion to plastically deform the swaged portion.
ROLLER BEARING, RETAINER SEGMENT OF ROLLER BEARING FOR SUPPORTING MAIN SHAFT OF WIND-POWER GENERATOR, AND MAIN SHAFT SUPPORT STRUCTURE OF WIND-POWER GENERATOR
A tapered roller bearing (31a) has a plurality of retainer segments (11a, 11d) each having a pocket to house a tapered roller (34a), and arranged so as to be continuously lined with each other in a circumferential direction between an outer ring (32a) and an inner ring (33a). The retainer segment (11a, 11d) is formed of a resin containing a filler material to lower a thermal linear expansion coefficient. In addition, a clearance (39a) is provided between the first retainer segment (11a) and the last retainer segment (11d) after the plurality of retainer segments (11a, 11d) have been arranged in the circumferential direction without providing any clearance. Here a circumferential range (R) of the clearance (39a) is larger than 0.075% of a circumference of a circle passing through a center of the retainer segment (11a, 11d) and smaller than 0.12% thereof at room temperature.
Device for monitoring a set of bearings
A device monitors the operating temperature of at least one set of bearings in a plurality of sets of bearings. The at least one set of bearings is arranged between a shaft and a carrier. The carrier has at least one temperature sensor that senses the temperature of the at least one set of bearings and generates a signal representative of an operating temperature of the at least one set of bearings. The at least one temperature sensor is operatively electrically connected to at least one controller. The controller processes the signal from the temperature sensor, including determining the operating temperature of the respective at least one set of bearings and whether the operating temperature of the respective at least one set of bearings exceeds at least one threshold temperature. The controller memory holds a unique identifier associated with the at least one bearing set.
METHOD FOR INSTALLING A BEARING ASSEMBLY ON A STATIONARY COMPONENT
A method for installing a bearing assembly on a stationary component where the bearing assembly includes a bearing carrier, a stationary bearing ring rotationally secured to the bearing carrier and a rotatable bearing ring supported for rotation relative to the first bearing ring. The method includes inserting a portion of the bearing carrier into an opening in the stationary component or inserting a portion of the stationary component into the bearing carrier, using an alignment tool to position at least two exposed radial surface portions of the stationary bearing ring with a surface of the stationary component to produce a temporary alignment of a rotational axis of the stationary bearing ring with a central axis of the stationary component, after producing the temporary alignment, attaching the bearing carrier to the stationary component in a manner that maintains the alignment, and removing the alignment tool from the bearing ring.
