Patent number: 7249893Abstract: A rolling bearing and a rod end bearing are provided with a tilt mechanism and a rotary mechanism that are mutually independent. The tilt mechanism has a non-lubricated type spherical sliding bearing structure. The rotary mechanism has a rolling bearing structure which may or may not be sealed. By means of the non-lubricated type spherical sliding bearing structure, a tilt of the shaft center is made possible, and by means of a sealed rolling bearing structure, problems such as a lubrication oil leak are avoided, and carrying out high speed rotation and continuous rotation become possible. Because the sealed rolling bearing structure of the rotary mechanism does not call for a shaft center tilt function at all, the material of the seal can be chosen such that it emphasizes sliding resistance and high durability.Type: GrantFiled: February 21, 2003Date of Patent: July 31, 2007Assignee: Minebea Co.

Patent number: 4060331Abstract: A ball-joint coupling comprises a male coupling member and a female coupling member. The male coupling member includes a ball to which a layer of elastomeric material is bonded. A part-spherical cap is received on the ball over said elastomeric layer and is bonded to such layer. The female coupling member has a part-spherical socket to receive the cap. Retaining means are operative between the cap and the female coupling member to prevent relative rotation of the cap in the socket at least in the horizontal plane, so that relative movement between the male and female coupling member results in deformation of the elastomeric layer and consequent damping of the movement.Type: GrantFiled: May 21, 1976Date of Patent: November 29, 1977Assignee: Societe PaulstraInventors: Michel Domer, Jean-Yves Hay

Patent number: 3978276Abstract: There is disclosed a spacer-damper for electrical transmission cables or the like. A rigid spacer composed of mating half-sections has defined at its extremities hollow spherical sockets for receiving the spherical end portions of individual cable connector structures. The opposite ends of the connectors are fashioned for effecting a gripping connection with a cable. A resilient damping material is interposed between the spherical connector end portions and their associated receiving sockets and the damping material is secured to both the ball and the socket so that on pivoting of the connector arm attendant cable vibration or oscillation the damping material is placed in shear to effect a damping action.Type: GrantFiled: May 2, 1975Date of Patent: August 31, 1976Assignee: Preformed Line Products CompanyInventors: James C. Poffenberger, William F. Corkran, Ralph B. Siter, Jr., Raymond J. Champa
