A friction damping cast component and method of production are disclosed. The components may be rotary, such as a cast brake rotor, or may be non-rotary, such as a cast suspension part or a cast engine block. Regardless of the type of component, a two-part vibration-damping insert having a thin metal core and a thin metal sheath is provided. The sheath fully encompasses the core in such a way that a dry sliding friction contact develops at their interfaces. The outer surface of the sheath with the metal core inside is rigidly bonded to the cast material that surrounds it during the casting process. The sheath surfaces may have a number of openings that allow a limited infiltration of molten cast iron material just inside the immediate vicinity of the sheath openings for spot rigid bonding between the surrounding cast material and the insert surfaces during casting.

In one aspect of the present disclosure, a module is disclosed for use with a digital image capturing device (DICD) including an integrated sensor-lens assembly (ISLA). The module includes a cradle configured for connection to a housing of the DICD, and at least one dampener that is configured for positioning between the module and the housing of the DICD to reduce vibrations transmitted to the ISLA.

Dampers and a fuel delivery systems including such dampers are disclosed. The damper includes a first component and a dampening component. The first component is coupled to a first tubular element and includes a first extended hollow section. The dampening component is coupled to a second tubular element. The dampening component includes a first end portion including a plurality of slits. The first end portion is disposed within the first extended hollow section to frictionally couple the first end portion to the first extended hollow section.

A positioning apparatus for positioning a tactile or optical roughness sensor, a probe or some other measuring instrument with respect to a workpiece can be secured to a movement device of a coordinate measuring machine. The positioning apparatus has a drive that produces a relative movement between two parts of the positioning apparatus, and an inhibiting device, which inhibits the relative movement between the two parts. For this purpose, the inhibiting device has a first friction element and a second friction element each having unlubricated friction surfaces. The friction surfaces are pressed against one another with a normal force that is not variable during the operation of the positioning apparatus. A coefficient of sliding friction that is less than 0.15 acts between the friction surfaces in the case of dryness and without lubrication. Typically, the inhibiting device is arranged in a flexspline of a strain wave gearing.

Described herein are energy absorbing apparatuses and methods of their use that utilize varying energy absorbing relationships between the apparatus members to absorb an energy input. The energy absorbing process occurs via a material forming process.

A damping device for a shaft in rotation around an axis of rotation parallel to a direction (A). The said damping device includes a support, a plate, a collar, and clamping means. The said support is stationary and is provided with a first opening, with the said plate being provided with a second opening and the said collar being provided with a third opening. The said shaft passes simultaneously through the said first, second, and third openings with, respectively, a first radial gap, a second radial gap, and a third radial gap, with the said third radial gap being smaller than the said first and second radial gaps. The said collar is movable with respect to the said support in a plane perpendicular to the said direction (A), with the said clamping means pressing the said plate against the said collar and the said collar against the said support.

The present disclosure provides a damping hinge structure and a foldable electronic device. The damping hinge structure includes a housing, a shaft that is mounted in the housing and includes a first end and a second end opposite to the first end, an actuating structure that is mounted on the shaft between the first end and the second end and enclosed in the housing and is configured to drive the shaft to rotate relative to the housing, and a damping structure configured to damping rotation of the shaft driven by the actuating structure.
