Methods and systems for a mechanically driven pump are provided. The mechanically driven pump may apply a piston simultaneously to operate as a guillotine blocking valve and a component to transfer motive force. A spring may apply a force to the piston to oppose a force that is applied to the piston via a cam lobe. The mechanically driven pump exhibits a differential pressure at a calibrated orifice during two working phases of the pump (expansion and compression), which provides for a non-zero volumetric efficiency of the mechanically driven pump.

Compact volumetric pump

A gearbox including: a fixed housing; a first wheel housed in the fixed housing; a second wheel housed in the fixed housing; a duct, where the duct is fixed to the gearbox; and a baffle interposed between the first wheel and the second wheel, wherein the duct is configured to transport a fluid to the first wheel, wherein the baffle is configured to transport fluid from the first wheel to the second wheel, and wherein the baffle is fixed to the fixed housing.

Lubricant system including a baffle

The present disclosure relates to a lubricant collection assembly, comprising:

Lubricant collection assembly

A fluid distribution system is disclosed herein for mechanical systems, such as vehicle transmissions with forced lubrication. The fluid distribution system may comprise: a fluid distribution system, comprising: a fluid distribution device positioned in a hollow shaft comprising a coaxial passage and a plurality of radial channels, the fluid distribution device comprising: a cartridge coaxial with the hollow shaft, comprising a first circular side having a coaxial inlet opening and a second circular side having a plurality of tube openings positioned equidistantly from an axis of rotation of the hollow shaft; and a plurality of pipes, each pipe extending from one of the plurality of tube openings parallel to the axis of rotation of the hollow shaft, where a length of each pipe corresponds to axial positions of the plurality of radial channels axially spread apart along the hollow shaft.

Fluid distribution system and device

Methods and systems are provided for a lubricating apparatus for a gearbox. In one example, an apparatus may include a curved shroud enclosing a portion of a gear, a first side oil collector and a second side oil collector, an oil reservoir having a first end fluidly coupled to the first side oil collector and a second end fluidly coupled to the second side oil collector, and a metering orifice fluidly coupling the oil reservoir to the curved shroud. The oil reservoir further includes at least two U-turns between the first end and the second end, and walls of the oil reservoir having multiple cavities.

Systems and methods for gearbox fluid reservoir

A lubrication assembly and operating method are provided herein. The lubrication assembly includes a rotating component an axial recess positioned on an axial side of the rotating component, and a lubricant conveyor that remains stationary relative to the rotating component and extends into the axial recess to form a gap between axial recess and the first lubricant conveyor. The lubricant conveyor directs a lubricant toward the axial recess during rotation to generate a lubricant spray focused in a targeted direction.

Lubrication assembly with a lubricant conveyor

Methods and systems are provided for a lubricant distribution assembly comprising a rotating component with a recessed circumferentially surrounded by a radially outer section, the radially inners side of which forms a surface of an undercut groove. The lubricant distribution assembly further includes a lubricant sump separated from the rotating component by a wall, a hollow tube that delivers lubricant from the lubricant sump to the lubricant distribution assembly and a lubricant deflector positioned within an upper portion of the lubricant distribution assembly and which lies in a plane that is parallel to a first axial side of the rotating component.

Systems for lubricant distribution

A lubricant or fluid distributor may have a housing made in one piece and comprising an inner wall and an outer wall. The inner wall encloses an inlet chamber fluidly connected with an outside of the housing through a fluid inlet. A main chamber may be formed in between the outer wall and the inner wall, the main chamber fluidly connected with the inlet chamber and fluidly connected with the outside of the housing through one or more fluid outlets. A lubricant fitting member may be encapsulated within the inlet chamber. A system with the lubricant or fluid distributor may have a part to be lubricated.

Distributor for a lubricant or fluid and a system with a distributor

A system and method for lubrication system are provided. The lubrication system includes a floater container including a floater compartment that contains a buoyant floater, where the floater container is coupled to a housing bulkhead and where the floater container includes an inlet opening in a first wall that is off-axis from a horizontal plane and forms an angle with a second wall. Further, the housing bulkhead includes an outlet opening positioned lower than the inlet opening and provides fluidic communication between the floater compartment and a rotating component compartment that contains a rotating component.

Lubrication system with a flow regulating floater container

The present disclosure relates to methods and systems for 3D printing. In one example, a 3D multi-layer structure is printed with a cavity distributed over multiple layers of a first filamentary material and shaped as a double-headed rivet. Further, the cavity is filled with a second filamentary material in a vertical direction to form a filament-based rivet, the vertical direction perpendicular to the plane of the multiple layers.
