  • Publication number: 20130074619
    Abstract: A rotary shaft positioning device is a simplified structure provided with rotating and positioning actions. The rotary shaft positioning device includes a housing defined with a tank chamber, a rotator disposed in the tank chamber of the housing, and a reactor. The housing is formed as a type of geometrical section. The rotator including a limiting portion is rotated while being accompanied by the rotation of the rotary shaft. The reactor is configured in between the tank chamber of the housing and the rotator to constantly press on the rotator, so that the reactor and the rotator form an interference status therebetween. The reactor and the rotator relatively form a frictional resistance to attain a positioning action when the rotary shaft is rotated, thereby reducing the complication of the positioning assembly device and improving the overlength of the assembling configuration of the positioning mechanism in conventional skills.

  • Publication number: 20090000407
    Abstract: A control device is provided for a technical system (17), e.g. for a shift-by-wire vehicle transmission. The control device includes a control (actuating) element, e.g. a rotary knob (1), with at least two shifting positions. The control element (1), itself, can rotate without limitation, whereas the control device has at least one stop device (2, 3), which can be adjusted in a controlled manner and which limits the angle of rotation (W) of the control element (1).

  • Patent number: 6594619
    Abstract: An apparatus is described for detecting the early signs of cycle-induced fatigue and thereby predicting failure of the rotating disk in turbo-machinery. It identifies asymmetrical growth of hub-blade diameter as a predictor of incipient crack growth. Tip measurements are processed through specialized algorithms to detect such asymmetry during operation, providing a real-time, non-destructive method of prediction. The sensors can be housed within the machinery case, and are capable of operating in harsh environments while maintaining adequate stand-off distance, making the entire apparatus robust enough for conditions in high-speed turbo-machinery.
