Abstract
A stuffing gland for shafts subject to relatively high pressures acting thereon in one longitudinal direction and comprising a flange disposed around the outer periphery of the shaft and having one side thereof open to the high pressure acting on the shaft, the flange being connected with the shaft for transmitting the force created by the pressure acting thereon to the shaft ina longitudinal direction opposed to the action of the high pressure surrounding the shaft, the area of the flange open to the high pressure being equal to the cross sectional area of the shaft for balancing the forces acting of the shaft for ease of operation of the shaft.
Claims6
A stuffing gland for a shaft subjected to relatively high pressures and comprising first plate means secured around the outer periphery of the shaft and having a central bore provided therein surrounding the shaft, outwardly extending circumferential flange means provided around the outer periphery of the shaft and disposed in the central bore, second plate means secured adjacent the outer surface of the first plate means for retaining the flange means in said central bore, pressure chamber means provided between the second plate means and one side of said flange means, means provided for relieving pressure at the opposite side of said flange means, passageway means extending through the first plate means for communication said relatively high pressures to the pressure chamber means, and the area of the flange means exposed to the pressure in the pressure chamber means being equal to the cross sectional area of the shaft for balancing the forces acting on the shaft.
