Abstract: A torsional vibration damper includes a common axis of rotation extending along an axial direction, an input part, an output part, rotatable relative to the input part in a limited manner with torque transmission, and a ramp system. The ramp system includes an axially displaceable component, a plurality of rolling elements for converting rotation of the input part relative to the output part into an axial shifting of the axially displaceable component, and a plurality of energy storage elements. The plurality of energy storage elements are arranged distributed along a circumferential direction, extend along the axial direction, and are elastically deformable in the axial direction.

Abstract: Mechanisms to realize lightweight rotational joints having independently adjustable compliance in one or more degrees of freedom are presented herein. In addition, robotic systems incorporating one or more compliant rotational joints as described herein are also presented. In some embodiments, a robotic structure includes a member having adjustable rotational compliance. One or more compliance elements are arranged around a rotational joint. The position of the one or more compliance elements relative to the rotational joint is adjusted to change the overall joint compliance. In some embodiments, the change of position of the one or more compliance elements relative to the rotational joint changes both the induced displacement of the compliance element for a given angular displacement of the rotational joint and the length of the moment arm from the rotational joint to the compliance element.

Abstract: A rotary device includes a first rotor, a centrifugal element, a first urging member, and a second urging member. The first rotor includes a guide surface and is disposed to be rotatable. The centrifugal element is attached to the first rotor. The centrifugal element is radially movable along the guide surface by a centrifugal force acting thereon in rotation of the first rotor. The first urging member is configured to urge the centrifugal element. The second urging member is configured to urge the centrifugal element in a direction opposite to a direction of urging by the first urging member. The first and second urging members are further configured to rotate the centrifugal element toward the guide surface.

Abstract: An internal combustion engine system includes an internal combustion engine, an exhaust system, an exhaust gas recirculation circuit and a turbocharger including a first turbine interacting with a first compressor for charging air to the internal combustion engine. An exhaust gas recirculation passage is arranged to divert exhaust gases from the internal combustion engine upstream the first turbine and to debouch the exhaust gases downstream the first compressor. The internal combustion engine includes a bleed air channel which is located to divert compressed air at a location in or down¬stream from the first compressor and upstream of the internal combustion engine. A second turbine is arranged for receiving bleed air from the bleed air channel to recover energy from the bleed air channel. A vehicle including such an internal combustion engine system is also provided.

Abstract: According to one embodiment, an apparatus for manufacturing a display device, includes: a first holding section configured to hold a first substrate; a second holding section configured to hold a second substrate; a turning section configured to turn the first holding section such that the first substrate and the second substrate face each other; a support section configured to support the first holding section after the turning; an adjustment section; and an elevation section. The adjustment section is provided at an upper end of the support section and is configured to adjust a distance between the first holding section after the turning and the upper end of the support section. The elevation section is configured to elevate the second holding section and attach the first substrate and the second substrate via an adhesive layer.

Abstract: A rotating torque transmission buffered shaft is provided with a casing tube, a shaft tube and a lock mounting member. The casing tube is formed with a receiving space and the inner walls of both ends of the casing tube are formed with a first inner screw thread and a second inner screw thread respectively. The shaft tube is installed within the receiving space and the middle section of the shaft tube is formed with a screw thread portion corresponding to the first inner screw thread. The lock mounting member is engaged and locked on the second inner screw thread. The rotating torque transmission buffered shaft is applicable to ships and vehicles for public transportation. The buffered shaft can absorb and balance intense rotating torque generated instantly, and can reduce the torque difference generated during the operation due to the linkage between the engine and the transmission device.

Abstract: A flexible shaft coupling has first and second hubs, each of which is provided with flanges and connected to a transmission shaft. The flange of the first hub has spring holes extended therethrough. A cover is fixed to the second hub so that the flange of the first hub is held between the cover and the flange of the second hub, and the cylindrical part of the first hub extends through the cover. A plurality of coil spring sets each comprises multiple barrel-shaped coil springs. Each of the coil springs is supported in the spring hole so that the adjoining end faces thereof are in contact and in series with each other.

Abstract: A connecting assembly for transmitting torque between a rotational part (11) having through-holes (13) and an attaching flange (17). Bolts (21) pass through the through-holes (13) and are threaded into threaded holes (18) to bolt the rotational part (11) and the attaching flange (12) together to transmit torque. The bolts (21) have a bolt shank (23) and a threaded portion (24), wherein the diameter of the shank (D1) is greater than the diameter of the threaded portion (D2). The through-holes 13, on the inside, include radial projections (15, 16) which reduce the cross-section and which are radially deformed when the bolts (21) are inserted and threaded in, so that bolts (21), by way of the bolt shank (23), rest in a play-free way against the projections (15, 16) in the through-holes (13) of the rotational part (11).
