<p>Previous retention arrangements have suffered from fretting or high contact stresses as a result of rolling between members retained by a retainer ring 23 in the form of a split ring. In order to address these problems a retainer arrangement is provided in which a retainer 33, 43, 53 is arranged at an inclined angle relative to a mounting axis for members such as a coverplate 31, 41 and mounting disc 32, 42. In such circumstances, in view of the angular presentation of the retainer, distribution of axial thrust loads can be aligned and through shaping of the retainer in terms of symmetry it will be understood centrifugal loads can be balanced as required. Typically, the retainer as indicated will be a split ring and the retainer for assembly and disassembly will be moved in a displacement direction consistent with the inclined angle so that the retainer enters a recess 35, 45 to allow disassembly or assembly of the members 31, 41, 32, 42.</p> |
