Title: Hydraulic machine
Inventor: NAGAFUJI TOMOTAKE
IPC: F04D29/66
Filed: 1981-11-13
Abstract: PURPOSE:To reduce the vibration stress to be produced in a vane by selecting Zr and Zg to be in the predetermined relation such as Zg=10, 15, 16, 20, 24, 25, 30 for Zr=5, assuming Zr is the number of vanes of a runner in a hydraulic machine while Zg is the number of the guide vane.

Title: Ring packing for gland packing
Inventor: UEDA TAKAHISA
IPC: F16J15/24
Filed: 1989-07-14
Abstract: PURPOSE:To prevent adhesion of a seal member to a packing box and to decrease a fastening force for generating an enough deepmost part pressure by a method wherein a reinforcing ring having an outer diameter lower than that of a seal part is engaged with a recessed part formed by mutually inclinably and axially notching the outer peripheral surfaces of a pair of adjoining annular seals. CONSTITUTION:The outer peripheral surface of an annular seal member 1 having elasticity is notched axially inclinably, and a notch recessed part having an approximately right angled apex is formed in the peripheral edge parts of the adjoining seal member 1. A reinforcing member (ring) 2 having high rigidity and approximately in the shape of a triangle in cross section and having an outer diameter slightly lower than that of the seal member 1 is engaged with the notch recessed part. This constitution reduces a friction force between a ring packing P1 and a packing box B and decreases bearing damping since even when an axial compression force is exerted on the annular seal member 1, the surface thereof is expanded toward the outer peripheral side and the seal member is prevented from adhesion to the packing box B. Further, propagation of a fastening force against the seal member 1 is smoothed, and the unbalance of an amount of axial fastening against the seal member 1 is prevented from occurring.
