Compliant mounting systems, devices, and methods for mounting a vehicle engine to a vehicle structure or base include a top mount, a lower mount, a center trunnion mount, and an aft mount which are configured to react forces transmitted by the engine to the vehicle structure. Metallic and elastomeric elements can provide vibrational and force isolation characteristics. Stops (e.g., snubbing elements) allow for a specific range of motion before internal mount structures contact each other to act as a conventional hard mount. Fluid elements and compressible gas-filled spaces/bladders may be incorporated to provide fluid damping behaviors to complement the metallic and elastomeric elements.

A motor support comprises two coaxial rings (20; 22) and an element for limiting the tilting of the inner ring relative to the outer ring. The limiting element comprises a finger (26) projecting from a first of the rings (20; 22) and housed in a receptacle (28) in the second of the rings (20; 22). An axial end-stop in the receptacle (28) limits the movement of the finger (26) in the receptacle (28) in the direction of the common axis (A) of the two rings (20; 22). The axial end-stop comprises a spigot (32) extending from a base (38) of a peg (36) through a wall (45) of the receptacle. The base (38) of the peg (36) is fixed to the second ring. The spigot (32) has a projection (44) capable of abutting against the wall (45) of the receptacle (28).

An assembly for supporting and guiding a drive shaft for an aircraft turbine engine includes a bearing support having a cylindrical housing for receiving an outer ring of a bearing, and a device for rotationally retaining a first portion of the outer ring which is detached from its attachment to the bearing support. When the detachment occurs, the free outer peripheries of the first teeth of the first portion cooperate by wedge effect in the tangential direction with complementary inner surfaces of the housing of the bearing support and/or the free inner peripheries of the second teeth inside the housing cooperate by wedge effect in the tangential direction with complementary outer surfaces of the outer ring.

An assembly is provided for a piece of rotational equipment with an axis. This assembly includes a static structure, a bearing within a bore of the static structure, and a centering spring mounting the bearing to the static structure. The static structure is configured with the bore, a slot, a first slot surface and a second slot surface. The slot extends radially into the static structure from the bore. The slot extends axially within the static structure between the first slot surface and the second slot surface. The centering spring includes an annular hub and a mounting tab. The annular hub is within the bore. The mounting tab projects radially from the annular hub into the slot.

An attachment system intended to equip a wall (17), the system including a nut intended to receive a screw (31) of which the orientation is normal to the wall (17), the screw (31) passing through an element such as an outer panel (32) in order to attach the element to the wall (17). The attachment system comprises a socket (26) having a threaded cylindrical outer face (34) intended to be screwed into a hole (29) passing through the wall (17) and having dimensions greater than the dimensions of the fastener that the repair socket (26) replaces, the socket (26) carrying, in the central region of same, a nut (28) receiving the attachment screw (32).

An exhaust-gas turbocharger (1) having a turbine housing (2), having a compressor housing (3), having a bearing housing (4), which has a bearing housing axis (L), and having a connecting device (5), for connecting the bearing housing (4) to the compressor housing (3) and/or the turbine housing (2). The connecting device has a plurality of connecting elements (6) which each have a connecting element end face (7). The number of bores (8) in the compressor housing (3) corresponds to the number of connecting elements (6). The bores (8) and the connecting elements (6) inserted into the bores (8) are arranged at an acute angle (α) with respect to the bearing housing axis (L), and the connecting element end faces (7) rest on an associated bearing surface (9) of the bearing housing (4) and/or turbine housing (2).

A pumping system featuring a pump chamber configured with a central portion having a tangential outlet, and configured with a tubular coupling end portion having inwardly flexible rim portions on one side; and a mounting base, having a circular portion with an inner circumferential rim configured to receive and engage the inwardly flexible rim portions of the tubular coupling portion of the pump chamber so as to be rotationally coupled to the pumping chamber so that the pumping chamber may be rotated 360° in relation to the mounting base.

A gas turbine engine rotor having an axis, comprising: a body about the axis having an inner surface, a seat having an outer seat edge at a first radial location surrounded by the inner surface at a second radial location, a lip along the inner surface having an inner lip edge spaced axially away from the seat to define a gap, the lip at a rated axial location between the inner lip edge and the seat facing toward the seat at a normal angle; a damper in the gap having first and second damper surfaces, the first damper surface adjacent the seat; and a split ring in the gap adjacent the second damper surface, having an outer ring edge spaced from the inner surface, engaging the lip at the rated axial location and resiliently expandable against the lip deflects the split ring to load the damper against the seat.

A pump cartridge comprising an external housing including a lateral wall, a first fin extending from a first side of the lateral wall, and a second fin extending from a second side of the lateral wall. The second side of the lateral wall may be opposite the first side of the lateral wall, such that the fins are on opposite sides of the lateral wall. The pump cartridge may be part of a pumping system further comprised of a chassis comprising a pump basin including an interior side wall, a first tab extending inwardly from the interior side wall, and a second tab extending inwardly from the interior side wall and opposed to the first tab. The first fin of the cartridge is reversibly engageable with the first tab of the chassis and the second fin of the cartridge is reversibly engageable with the second tab of the chassis.
