Abstract
Flexible joint means for fluid conduits comprises an outer tubular member, an inner tubular member having an end portion positioned within the outer member and a bearing assembly acting between the outer and inner members. The bearing assembly comprises first and second bearings each of laminated construction comprising interleaving layers of elastomeric material and reinforcement material. The bearings are disposed on opposite sides of an annular collar associated with an inner member and act between the collar and a pair of axially spaced annular flanges associated with an outer member. Collar and flanges extend axially and radially such that one bearing is disposed radially inwards of the outer bearing. The radially inner bearing includes elastomeric material having a higher modulus of elasticity than the elastomeric material of the outer bearing such that the bearings have substantially similar axial stiffnesses.
