Abstract
Systems and methods for connecting misaligned pipe sections, where two sets of variably spaced bearings enable the transfer of evenly distributed pressure from a collar member to a coupling member. One embodiment comprises a misalignment coupling that includes first and second coupling members, a collar, and two sets of bearings. The collar is positioned around the second coupling member and has a flange for coupling to a flange of the first coupling member. The bearings are positioned in an annular space between the second coupling member and the collar. The two sets of bearings have variable spacing and are interleaved, with one set contacting the collar and one set contacting the second coupling member. When the flanges are secured to each other, contact pressure is transferred from the collar through the bearings to the second coupling member, thereby applying contact pressure between the first and second coupling members.
