A thrust bearing which is formed by stamping a plate made of a bearing alloy material or a plate having a bearing alloy layer has an annular shape. The thrust bearing is disposed in a circumferential direction and has a plurality of recesses and projections deformed in the direction of the thickness of the bearing. The thrust bearing may have a positioning and retaining portion.

A thrust bearing characterized by simplicity of construction and improved life and including a pair of bearing races with a cage and rolling elements positioned between the races. Arcuately spaced lugs integrally formed on one bearing race extend in an axial direction and are provided with latching members thereon to engage the other bearing race and thereby hold the bearing races and the cage in assembled relation. An improved one-piece cage is disclosed having portions on each face of the cage...

A hybrid hydraulic-pneumatic thrust generator wherein pneumatic action is used for cocking and for cushioning while hydraulic action is used for providing the driving force. The output can be increased by reducing the cocking or cushion gas pressure required to dislodge the poppet valve from its seated position in the driving port by introducing pressurized oil into the driving port between the poppet valve and poppet actuator. The thrust generator of this invention has a relatively flat thrust ...

Disclosed is a thrust retaining device for positive axial securing of a part on a smooth shaft or within a smooth bore without shoulders, threads, grooves or holes. The thrust retaining device for use on a shaft includes a contractible inner collar ring for retaining thrust by having one end positioned against the part to be secured, an outer collar ring to be placed over the inner collar ring for contracting it, and loading screw means attached to the outer ring for applying axial force to the ...

An improved thrust bearing particularly suited for use in applications wherein the bearing is subjected to cocking loads in addition to thrust loads. The bearing includes first and second relatively rotatable members with one of the members including a thrust collar. The other of the members includes a groove receiving the thrust collar and a bearing surface is interposed between the thrust collar and the groove. The groove, collar and bearing surface are constructed and arranged such that a cle...

A thrust bearing for use with a shaft having a collar mounted thereon, comprising a base ring, a thrust bearing shoe having a leading edge connected to a trailing edge by an inner diameter edge and an outer diameter edge and having a working face with a bearing liner on its surface, a series of shoes positioned on the base ring, a shoe pivot on each shoe allowing the shoe to pivot in any direction, an oil distribution groove formed in the working face near the leading edge of the shoe and extend...

For a long dual mixer nacelle housing a fan-jet engine powering aircraft, a pair of concentric sleeves sandwiching the cascades to effectuate thrust reversal are synchronously deployed axially to communicate the fan discharge air in the duct with ambient through the cascades. A rack and gear connection between sleeves permits the independent linear motion of each of the sleeves so that the actuation of one automatically actuates the other without the necessity of attaching both to each other.

A thrust unit for a space vehicle has a container in which an electrolyte is electrolyzed to produce combustible gases (for example, water producing hydrogen and oxygen). At a predetermined pressure the gases are ignited and combustion products are exhausted from the container through a thrust nozzle. The pulsed nature of the thrust unit operation, and the duration of each pulse, are such that overheating of the unit is avoided.

A thrust bearing or tapered-land thrust bearing including a plurality of lubricant feeding nozzle holes. At least one of the nozzle holes is disposed in close proximity to the leading edge of a tapered surface of a bearing surface of the thrust bearing. By this arrangement, hot oil carryover can be minimized and the temperatures of a film of lubricant formed between the bearing surface and a thrust collar positioned there-against and a bearing body of the thrust bearing can be reduced. Thus the ...

A thrust reverser for a fan jet engine having a splitter in the fan duct in a plane with the fixed cascades is designed with blocker doors positioned to block flow between the splitter and the outer wall when in the deployed position. The splitter and supports are positioned to simultaneously uncover the cascades and block flow in the remaining portion of the duct. This design contemplates elimination of the blocker door drag links that typically extends into the duct passageway.
