  • Patent number: 11066957
    Abstract: An axial-flow fluid machine provided with: a retainer ring holding a stationary blade train; a casing supporting the retainer ring; and an eccentric pin. An engagement part of the casing has a protruding section protruding to the retainer ring side. An engagement part of the retainer ring has a pair of wall plate sections forming a groove into which the protruding section is put. In the casing, a penetration hole is formed extending in a radial direction so as to be centered about a penetration center position that is biased to an axial upstream side in a region of the casing where the engagement part is formed. In the engagement part of the casing, a portion on an axial downstream side relative to the penetration hole exists in the entire circumferential area. The eccentric pin is inserted into the penetration hole.

  • Patent number: 5236031
    Abstract: A pneumatic radial tire for construction vehicle comprises a carcass of a radial structure comprised of at least one rubberized steel cord carcass ply body and its turnup portion, and a stiffener rubber arranged above a bead core between the carcass ply body and its turnup portion. In order to improve the bead portion durability of this tire, a cord distance between the carcass ply body and its turnup portion passes through greatest value, minimum value, maximum value and smallest value from the vicinity of the bead core outward in the radial direction of the tire and heights of the carcass ply body corresponding to the above minimum and maximum values as well as height of the turnup end measured from the base line satisfy particular relations to a flange height FH of the standard rim.

  • Patent number: 5180457
    Abstract: A pneumatic radial tire for construction vehicles comprises a radial carcass of rubberized steel cord ply, a stiffener rubber disposed on a bead core, and at least two reinforcing layers of rubberized fiber cord fabrics having different cord directions as a bead portion reinforcement. This reinforcing layer satisfies the particular height relations to the carcass ply and its turnup portion.
