摘要： PURPOSE:To provide an elastic wheel capable of restraining an elastic body which composes the elastic wheel from heating and reserving heat and also maintaining stability and durability of the elastic body during its high speed travel. CONSTITUTION:A wheel plate 2 integrated with a wheel axis 1 and a wheel plate 4 integrated with a tire 3 are commonly held between compound bodies A metal stiffening plates 5 are laid thereon and the compound bodies A, are fixed to the wheel plate 2, 4 by means of bolt/nut clamps 6. The compound bodies A are of a laminated body formed by sticking and laminating alternately high rigidity thin plates (0.1 to 5.0mm thick) such as steel plates, and high molecular visco-elastic layers (0.02 to 5.0mm thick) of a rubber or a synthetic resin. In this elastic wheel, vibration of a vehicle is absorbed by the high molecular visco-elastic layers of the compound body A, when a vehicle load actuates to the compound body A while taking the load as a force towards the shearing direction and the compression direction. The shearing deformation of the high molecular visco-elastic layers occurring at that time can be kept small and the heating may be restricted to the minimum.

摘要： PURPOSE:To provide a vibration damping material displaying favorable vibration damping properties in a wide temperature range. CONSTITUTION:A magnetic, polymeric and viscoelastic sheet is formed of a composition constituted of rubber-elastomer, viscous resin, a plasticiser and magnetic powder, in a magnetic composite vibration damping material which is constituted by sticking the magnetic, polymeric and viscoelastic sheet 3 containing the magnetic to a constraint plate 1 such as a metallic plate by an adhesive agent 2. Since in a constituent vibration damping material, magnetic, polymeric and viscoelastic sheet 3 is provided with not only holding of suction force by magnetic force to a vibration source 4 but also surface adhesion, favorable vibration damping effect is displayed in a wide temperature range by a synergistic effect of both magnetic force and adhesion.

摘要： PURPOSE:To improve the extensibility, tear strength, tensile strength and modulus by using rubber, fibrous polytetrafluoroethylene, a vulcanizing agent, and an inorganic filler as constituents. CONSTITUTION:A polytetrafluoroethylene powder and an inorganic filler are kneaded under a high shear force to give a fibrous polytetrafluoroethylene powder and to disperse the inorganic filler among the fibers. 100 pts.wt. rubber is mixed with the polytetrafluoroethylene in an amount of 1-20 pts.wt. and a vulcanizing agent.

摘要： PURPOSE:To provide a composite damping material capable of being simply mounted to a vibrator in a detachable manner and reduced in the temp. dependence of damping characteristics and capable of developing effective damping capacity within a wide temp. range by containing a magnetic powder in at least one plate composed of a rigid body and/or at elast one polymer viscoelastic layer of a laminate and magnetizing the same. CONSTITUTION:Anti-corrosion films 2 composed of iron phosphate are formed to both surfaces of a metal plate 1. Next, a primer is applied to both surfaces of the anti-corrosion films 2 to form primer layers 3. A rubber solution is applied to the primer layer 3 on the single surface side of the metal plate and vulcanized to form a rubber layer 5 containing 80wt.% of strontium ferrite. The composite damping material constituted as mentioned above is brought into close contact with a magnetizing yoke on the side of the magnetic powder- containing rubber layer 5 to be subjected to magnetizing treatment by a condenser magnetizer. A magnetized pattern is formed so that N-poles and S-poles are alternately arranged on the plane of a magnetic body in a stripe form and the interval thereof is set to 1 - 10mm. As a rigid material other than the metal plate 1, a ceramic type one to which sintering treatment is applied or a synthetic resin one such as fiber reinforced plastic is used but the Young modulus thereof is desirably 300kgf/mm or more.

摘要： PURPOSE:To sufficiently develop control action due to slip friction even when an adhesive or pressure-sensitive adhesive comes into contact with a vibration body or when the vibration body is independently used as a structural material by a adding a magnetic powder in a plate composed of a rigid body and/or a polymer viscoelastic body and providing one or more contact surface closely bonded only by magnetic force provided by magnetization. CONSTITUTION:In a laminate formed by laminating a plate composed of a metal being a riged body and/or a rigid body other than a metal having Young's modulus of 300kgf/mm or more and/or a polymer viscoelastic body, a rubber layer 3 containing a magnetic powder and molded into a sheet shape by a press mold is formed to the single surface of the metal plate 1 through an adhesive layer 2. The rubber sheet of the rubber layer 3 is subjected to the magnetization treatment by a condenser magnetizing device in such a state that the surface thereof opposite to the surface bonded to the metal plate is closely brought into contact with a magnetizing yoke after the molding of the sheet but before the bonding to the metal plate. A magnetizing pattern is formed by single surface multipole magnetization so that S-poles and N-poles are alternately arranged on a flat surface in a stripe pattern and the interval thereof is 1-10mm.
