37、Load 2 Figure 31 27 7 11,12 7 3,8,9,1 O Description An assembly consisting of the adapter sleeve, locknut and lockwasher or lockplate. An axially slotted sleeve with a cylindrical bore, a tapered outside surface and a male screw thread at its small end. Use (with a locknut and a lockwasher) for the
38、mounting of a bearing with tapered bore on a cylindrical outside surface of a shaft. A rolling bearing which, by reason of design or execution, is intended for use in the general struc- ture of an aircraft, including its control systems. See External Aligning Bearing. A ring used between an aligning
39、 outer ring and a housing bore, having a spherical inside surface matching the spherical outside surface of the outer ring. A housing washer having a spherical back face to accommodate permanent angular misalign- ment between its axis and the axis of its housing. A bearing outer ring having a spheri
40、cal outside surface to accommodate permanent angular mis- alignment between its axis and the axis of its housing. A washer used between an aligning housing washer and the thrust supporting surface of a housing, one face of which has a concave spher- ical surface matching the spherical back face of t
41、he aligning housing washer. A radial rolling bearing with a nominal contact angle greater than 0 up to and including 45“. See Radial Bearing. The arithmetical mean of the axial distances through which one of the rings or washers may be displaced relative to the other, from one axial extreme position
42、 to the opposite extreme position, without being subjected to any external load. The mean value includes displacements with the rings or washers in different angular positions relative to each other and with the set of rolling elements in different angular positions in relation to the rings or washe
43、rs. A load acting in a direction parallel with the bear- ing axis.

Ball Grade Basic Dynamic Radial (Axial) Load Rating Basic Rating Life Cage Cage Pocket Cage Prong Cage Stay Cam Follower Capped Bearing Center Rib Chamfer A specific combination of dimensional, form, sur- face roughness and sorting
46、 tolerances for balls. That constant stationary radial load (constant ventric axial load) which a rolling bearing can theoretically endure for a basic rating life of one million revolutions. In the case of a single row angular contact bearing, the radial load rating refers to the radial component of
47、 that load which causes a purely radial displacement of the bear- ing rings in relation to each other. The rating life associated with 90% reliability. A bearing part which partly surrounds all or sev- eral of the rolling elements and moves with them. Its purpose is to space the rolling elements and
48、 generally also to guide and/or retain them in the bearing. An aperture or gap in a rolling bearing cage to accommodate one or more rolling elements. A cantilever cage bar projecting from the annular body of a rolling bearing cage or from one part of a two-piece cage. One of several parts used to join the two annular parts of a two-piece cage and to maintain them at a specified distance from each other. See Track Roller 11,12 A rolling bearing which is fitted with one or two seals, one or two shields or with one seal and one shield. 15,23 A central integra
