A cage and roller assembly in a hardened thrust bearing race is restrained within the race by heating a plurality of circumferentially widely separated parts of the race lip to soften the lip parts and bending the softened parts over the cage of the cage and roller assembly. An apparatus for assembling the thrust bearing includes a pair of electrodes located to apply a current through the lip to soften the lip and a form punch which is constructed to bend the softened part of the lip over a cage...

A thrust washer for a mounting assembly disposed below an opening in a deck for mounting a faucet above the opening in the deck. A plurality of water lines extend through the opening in the deck to be connected to the faucet. The thrust washer being wider than the opening in the deck and formed in the shape of a "W" with a central opening at its midpoint for connection thereof to the mounting assembly. The thrust washer has a pair of outer legs defining wings which create an enlarged space above...

A gas turbine engine which is used for aircraft propulsion, is provided with a pair of thrust deflecting doors which, when deployed, deflect the exhaust gases onto some path other than axially of the engine, so as to spoil the thrust. The doors are waisted in profile. To prevent some of the exhaust gases from missing the doors, when deployed, and thus reducing their functional efficiency, plane flaps are provided on the jet pipe, which can be moved into the gas stream when the doors are deployed...

The precision rotatable polygonal mirror of a laser scanning system is fixed to one of a pair of spaced flanges of a rotatable shaft, and has one surface supported upon a fixed air bearing. A floating air bearing is formed to define a differential piston which is pressurized to load the bearing and provide the desired air film bearing thicknesses. The two part thrust bearing has a net effective axial dimension that varies to significantly decrease required tolerances, to minimize moments introdu...

A thrust bearing has a plurality of bearing pads each provided on its back side with a pivot, and a support on which the pads are disposed in the circumferential direction. An integral carrier is mounted on the support. The carrier has leg portions and a resilient portion and definies a squeeze film damper portion between the rear surface thereof and the opposing surface of the support. The pads are carried tiltably by the carrier through the pivots.

A novel thrust bearing is provided in which a spiral element having a disc shape is loosely interposed between a pair of flat elements one of which is rotatable and the other of which is stationary, the spiral element having a spiral groove pattern on each of the opposite surfaces of the disc with the patterns on the respective surfaces reverse in relation to each other in their spiral direction.

A thrust bearing is disclosed for enabling relative rotation between coaxial first and second members. The thrust bearing includes a pressure transmitting washer for transmitting axial thrust pressure between the members, the washer being disposed coaxially relative to the members. The washer defines a first central aperture through which the first member extends, the washer being disposed adjacent to the second member. A flexible spring for transmitting axial thrust pressure between the first m...

Thrust augmentation apparatus for a propulsive gas jet 11 including: an outer augmentor housing 15 and an inner augmentor housing 21 arranged coaxially with the jet 11. A minor air flow 25 is drawn into the inner passage 24 by an ejector effect, that flow 25 driving turbine vanes 28 projecting inwardly but terminating short of the jet 11. The vanes 28 transmit drive to fan blades 13 in the outer housing 15 to promote a thrust augmenting air flow 14. As an alternative to turbine vanes 28, gas sco...

Gas turbine engines, usually of the kind which include ducted fans, have cowl structures which generate drag inter alia by virtue of their frontal area. Where the cowl is of very large diameter i.e. in the order of 3 to 4 meters, if known devices such as thrust reverser cascades are installed in them, the frontal area and weight of the structure would be unacceptable. The invention provides a cowl structure of the magnitude mentioned hereinbefore, in which an improved cascade is installed. The o...

Thrust pipe for disposition in a passage in the ground by advance of the pipe axially through the passage includes a plurality of pipe segments disposed in end-to-end relation one to the other. Each pipe segment includes an inner pipe section having a diametrically enlarged end for telescopically receiving the opposite end of an adjacent inner pipe section. The pipe segments each include an outer pipe section, substantially enveloping a corresponding inner pipe section. The outer surface of the ...
