<p>A flexible coupling (1) for transmitting torque has concentric inner (2) and outer (4) coupling members. The inner member (2) has a plurality of angularly spaced first projections (8) extending towards the outer member (4). The outer member (4) has a plurality of angularly spaced second projections (9) extending inwards towards the inner member (2). The first and second projections (8,9) define between them a plurality of pockets (11). An elastomeric coupling element (12) is disposed in each pocket (11). The coupling element (12) has a trilobe shape with a peripheral profile that is generally triangular with three sides (16), the three sides (16) being interconnected by three arcuate lobes (15). The radius of curvature of each side (16) is greater than the radius of curvature of each lobe (15).</p> |
