  • Hydraulically controlled cone disc continuously-variable transmission
    Patent number: 7955202
    Abstract: The invention concerns a continuously variable cone disc transmission with sets of discs mounted on drive and driven shafts. The sets of discs are each hydraulically adjustable axially in their distance from each other whereby the traction train circulating between them is able to adjust to different running circles and thereby enabling a continuously variable transmission. The pressure fluid needed for the hydraulic actuation is supplied to the pressure cylinders by a pump through a control valve. This control valve is actuated hydraulically by a pressure supply that is need-adjusted by a proportional-pressure reduction valve. In the event of a functional failure and consequent loss of the regulating pressure, the control valve is automatically arrested in position, so that the control valve is prevented from giving a command for the sudden change of the transmission ratio into an extreme position.

  • In on or relating to rotating machines
    Patent number: 7949479
    Abstract: A rotating machine, has a rotary component, which includes a memory device for storing data relating to the past use of the component. The data are associated with rotational speed and ambient temperature, which are detected by detectors either on or off the rotary component. The stored data may be the raw temperature and speed data as sampled over time, which are then used to derive values of low-cycle fatigue and creep damage. These fatigue and creep values are, in turn, correlated with the load profiles of the component to arrive at a value of elapsed lifespan for the component. Alternatively, the stored data may be the fatigue and creep values and/or, preferably, values of elapsed and remaining lifespan of the component. In a second embodiment the detectors are located on the machine casing along with an evaluation unit.
