A MECHANICAL JOINT FOR DAMPING VIBRATION

摘要

A mechanical joint for interconnecting e.g. the arm and body of a vibration damping coupling for cables comprises a housing formed in the body in which is received the end (3b) of the arm (3), and a plurality of rubber spheres (2) located between the arm and the housing. The arm is retained within the housing by a pin (6) which passes through a biconcave hole (7) in the arm to permit pivotal movement of the arm about three orthogonal axes. Rotation of the arm about any axis causes compression of at least two spheres. The spheres are not subject to shear forces.
