ABSTRACT:
In an elastic coaxial coupler, a cylindrical body of a first member is fitted through an opening in a second member seating said second member upon a flange on the first member. A circumferential groove in the cylindrical body has a conical groove surface confronting a surface of the second member adjacent the opening in the second member. An O-ring in tension around the cylindrical body at the circumferential groove, is drawn into the circumferential groove by the radial force component of the O-ring tension force and is compressed between the conical groove surface and the surface of the second member adjacent the opening in the second member, to securely frictionally engage the second member to the flange of the first member. In an application of this elastic coaxial coupler to a hard disk drive, the first member is the hub of a disk assembly and the second member is the hard disk. In a different application of this elastic coaxial coupler to a hard disk drive, the first member is the rotor of the disk motor and the second member is the hard disk hub.
