  • Method and system for measuring wedge tightness
    Publication number: 20050284241
    Abstract: A method for measuring wedge tightness in an electromechanical device includes providing a top ripple spring that includes a conductive portion and a non-conductive portion, positioning the top ripple spring at least partially within a stator slot defined within the electromechanical device, mapping a profile of the top ripple spring, and using the mapped profile to determine the wedge tightness in the electromechanical device.

  • Device and method for installing turbine generator stator wedges
    Patent number: 6708395
    Abstract: A tool for driving a stator slide under a stator wedge within a radial slot of a stator core includes a frame including a pair of elongated rail members, the frame provided with a pair of handles at respective opposite ends of the elongated rail members. A force application cart is located between the rail members, the force application cart having a drive block thereon. A drive is connected to the frame, substantially intermediate opposite ends of the frame, the drive having an on/off trigger located on one of the handles. A lead screw is threadably engaged at one end with the force application cart and connected at an opposite end to the drive such that the drive rotates the lead screw when actuate; wherein in use, rotation of the lead screw causes axial movement of the force application cart and the drive block along the elongated rail members.
