摘要： A method and device for fitting an angular contact roller bearing, including an inner bearing ring having an inner race arranged on the outer peripheral surface of the inner bearing ring and inclined with respect to the axis of rotation of the bearing, and a rim delimiting said race at the smallest diameter thereof, an outer bearing ring having an outer race arranged on the inner peripheral surface of the outer bearing ring and inclined with respect to the axis of rotation of the bearing, and a rim delimiting said race at the greatest diameter thereof, and also including a plurality of roller bearing elements arranged between the bearing rings and roll on the races and are held at uniform distances from one another in the circumferential direction by a bearing cage. The outer peripheral surface of the inner bearing ring and the inner peripheral surface of the outer bearing ring are in each case cylindrical and extend outside the races at least in some sections coaxially with respect to the axis of rotation of the bearing, and the races of both bearing rings are in each case integrated conically into the cylindrical peripheral surfaces, such that the rims which are produced and in each case delimit the races on one side are in each case formed in one piece with the bearing rings. The fitting of the angular contact roller bearing takes place according to an eccentric pivot fitting method the deep groove ball bearing eccentric fitting method.

摘要： A method and device for assembly of an angular contact roller bearing, including an inner bearing ring having an inner raceway arranged on the outer peripheral surface of the inner bearing ring, at an angle to the bearing rotation axis, and a rim delimiting said raceway at the smallest diameter thereof, an outer bearing ring having an outer raceway arranged on the inner peripheral surface of the outer bearing ring, also at an angle to the bearing rotation axis, and a rim delimiting the raceway at the largest diameter thereof, and a plurality of rolling element bodies, arranged between the bearing rings and rolling on the raceways thereof held at regular distances in the circumferential direction by a bearing cage. A tangent to the outer shell surface of the inner bearing ring and a tangent to the inner shell surface of the outer bearing ring are flat at least in the region of the raceways, and extend at inverse to the bearing rotation axis, and the raceways of both bearing rings are each conically formed in the peripheral surfaces such that the rims thus produced and delimiting each of the raceways on one side are consequently each integral with the bearing rings. The bearing is assembled according to an eccentric-pivot assembly method borrowed from the eccentric assembly method known for grooved ball bearings.

摘要： A spherical roller bearing having a specific pitch circle diameter (PCD) that includes an outer ring, an inner ring, a plurality of roller elements arranged in first and second roller rows, each roller element providing an axially inner end, and a cage for guiding the roller elements in the first and second roller row, the cage having a plurality of cage pockets. One of the roller elements disposed within each cage pocket. Each respective cage pocket has a bottom that faces the axially inner end of the roller element in each cage pocket. A radially inner end of the cage pocket bottom contacts the axially inner end of the roller element only at a location radially equal to the specific PCD, the cage pocket bottom angled such that the cage pocket bottom abuts the axially inner end of the roller element at an angle such the contact is not flush.

摘要： A bearing holder is to be formed by injecting a melted resin, from a plurality of resin injection gates provided at a peripheral edge portion of a substantially annular cavity formed in a molding die, into the cavity. At least one column portion is provided with a resin reservoir capable of reserving therein the melted resin. A cross-sectional area of a communication portion of the resin reservoir configured to communicate with the column portion is equal to or smaller than ¼ of a cross-sectional area of the resin injection gate.
