A turbo-compressor including a variable vane that adjusts the flow rate of a fluid, a drive shaft that is connected to the variable vane and is rotated to drive the variable vane, a motor that rotationally drives the drive shaft, and a coupling that couples the drive shaft with an output shaft of the motor. Between the drive shaft and output shaft and the coupling, a vibration isolation means is arranged to connect the drive shaft and output shaft to each other so that they rotate together and allow the drive shaft and output shaft to move in a vibration direction.

The present invention relates to a rotational force driving assembly and a process cartridge used for being engaged with a rotational force driving head inside an electrophotographic image forming device. The rotational force driving assembly can comprise a hub, a rotational force receiving component, a side plate, and an axis offset adjusting mechanism. When the axis offset adjusting mechanism is not subjected to external force, the axis offset adjusting mechanism enables the axis of the rotational force receiving component to be parallel and offset to the axis of the hub. When the axis offset adjusting mechanism is subjected to external force, the rotational force receiving component extends out to be engaged with the rotational force driving head.

A drive system of a header for an agricultural vehicle. The header includes a plurality of driven devices. The drive system includes a shaft configured for conveying motive power from the agricultural vehicle to the header, a gearbox configured for being located on the header and for transferring motive power to the plurality of driven devices, and a torque damper. The torque damper is operably connected in between the shaft and the gearbox. The torque damper is configured for reducing a magnitude of a torque spike.

Transmission device (100), for example for a watch mechanism (110), in particular for a winding train (100, 201) of a watch movement (120), including an input element (6) intended to be driven only in a first direction, an output element, a first mechanical connection arranged such that the displacement of the input element in a first direction causes the displacement of the output element in a second direction, and a second mechanical connection (9′, 9) arranged such that the displacement of the input element in the first direction causes the displacement of the output element in a third direction, the third direction being opposite the second direction.

A drive-side rotor is rotated synchronously with a crankshaft. A driven-side rotor is rotated integrally with a camshaft. An internal gear section is formed at the driven-side rotor. An Oldham coupling includes: a driven Oldham flange that is formed at the drive-side rotor; a drive Oldham flange that is formed at the planetary rotor; and an Oldham intermediate that is configured to synchronize rotation of the driven Oldham flange and rotation of the drive Oldham flange while permitting eccentricity between the driven Oldham flange and the drive Oldham flange. There is satisfied a relationship of θ2<θ1 where: θ1 is a maximum tilt amount of the planetary rotor relative to the driven Oldham flange; and θ2 is a maximum tilt amount of the planetary rotor in a clearance formed at the Oldham coupling.

An Oldham coupling includes: a driven Oldham flange that is formed at a drive-side rotor; a drive Oldham flange that is formed at a planetary rotor; and an Oldham intermediate that is configured to synchronize rotation of the driven Oldham flange and rotation of the drive Oldham flange.
