A thrust bearing adapted for high and low pressure loading for supporting an end of a shaft for rotation about its longitudinal axis comprising a ball bearing confined in concentric relation at the end of the shaft to be supported and a part recessed into the end of the shaft which rests against the ball bearing structured to dissipate heat and of a composition such that at high loads and high velocity, it functions as a solid lubricant and at low loads and low velocity, it functions as a solid.

A gas turbine engine having variable geometry flow controllers therein for controlling mass flow in accordance with engine operation includes a rotor with a wide variation in thrust forces thereon during different phases of engine operation countered by a variable axial load integrating device having a rotating hydraulic thrust compensating piston mounted forwardly of the rotor in association with a rotor thrust bearing and further including means for generating a centrifugal head in accordance ...

This invention is a tilting thrust pad bearing in which bearing pads 11 are supported on individual pillars 19 which themselves bear on supporting bars 23, carried by rockers 24. The supporting bars and rockers are identical components and can be used in different numbers for large diameter and small diameter bearings, while yet where they support one another, there can be one point or two point connection by virtue of an arcuate ridge 41 at one end of each component, and a slightly domed surfac...

A thrust bearing for a shaft is disclosed including a shaft thrust collar arranged in steps. The stepped construction features an inside bearing surface and an outside bearing surface axially offset from the inside bearing surface. In the bearing body for each bearing surface, spring supported bearing units are provided. Each bearing unit consists of a bearing segment, a knuckle washer, and a flexible supporting bridge connected with each other by a connecting pin. Separate oil delivery and disc...

A rotary torque transmission device has at least one pair of balls or rollers transmitting a torque load through respective contact points or lines with driving and driven members of the device and a contact point or line with each other. The contact points (or lines) do not lie on the same line (or plane) whereby the torque load produces an offset force. This is resisted by resilient means and increases with the torque load until the force overcomes said resistance and causes substantially fric...

A thrust bearing configuration for rotary applications includes a shaft (12) having an external surface (14) and a housing (16) having an internal surface (18). The housing and the shaft are adapted for relative rotational movement. Inner bearing support members (22) extend radially outwardly from the external surface of the shaft in axially spaced relation. Outer bearing support members (26) extend radially inwardly from the internal surface of the housing. A bearing pad (24, 28) is disposed be...

A rocket engine thrust chamber comprising a combustion chamber having its fuel inlet-mixing section and thrust nozzle section formed of integrally interconnecting pyrolyzed graphite filaments so oriented and extended that the fibers thereof individually interconnect the thrust nozzle throat and fuel inlet-mixing sections of the engine, and provide more effective heat conduction from the nozzle throat section to the fuel inlet-mixing section. Accordingly, the temperature of the nozzle throat sect...

A device for augmenting the thrust from the prime thrust unit of a vessel wherein the thrust unit is surrounded by a shroud having a flared entrance placed in close proximity to the hull of the vessel so that the velocity of fluid being drawn into the shroud increases thus reducing the pressure of fluid acting on the leading face of the flared entrance to augment the thrust of the prime thrust unit.

An electromechanical thrust actuator including a cylinder having a cavity with a longitudinal axis, a piston received in the cavity for displacement relative to the cylinder along the axis, and electromechanical drive means disposed in the cavity and connecting to the cylinder and the piston for axially displacing the piston relative to the cylinder, wherein the electromechanical drive means includes a ring member disposed in the cavity and movable relative to said cylinder, a torsion spring dis...

The invention relates to axial thrust bearings for rotating shafts of electrical machines wherein large end thrusts are produced. A source of hydraulic pressure is provided, coupled with a pair of hydraulic pads mounted on each side of a flange on the shaft to apply counter forces maintaining the shaft in a neutral position.
