摘要： A turning system for rotating equipment, comprises a motor configured for speed control; a gear connected to the motor, the gear is further connected to the rotating equipment, the motor and gear are configured for rotating the rotating equipment at speeds less than the normal operating speed of the rotating equipment; and a controller configured to perform a method, wherein the method comprises a sequence of steps including, rotating the rotating equipment from a standstill an angular amount of rotation, stopping rotation after moving the angular amount of rotation, and maintaining the rotating equipment at a standstill for a period of time; and repeating the sequence of steps. By performing the sequence of steps after the rotating equipment comes to a standstill, bowing or sagging of the rotating equipment can be prevented, and the rotating equipment is ready to startup at anytime.

摘要： A device for fixing the position of adjustable vane rows of a turbomachine is disclosed. The device is intended for use with a turbomachine in which the guide vanes of a row of adjustable guide vanes are coupled together by a synchronizing ring. The device includes a support arm and at least one ring fixing set including a holding member and a fixing bolt. The fixing bolt is provided and dimensioned to engage an opening at the circumference of the synchronizing ring and to fix the position of the synchronizing ring and thus of the adjustable guide vanes coupled to the synchronizing ring.

摘要： A turbine blade tip shroud has a first cutter tooth extending from a tip rail from one of the upstream side and the downstream side of the tip rail and adjacent the leading edge of the body. The tip shroud also includes a second cutter tooth extending from the tip rail from the other side of the tip rail at a position axially distant from the first cutter tooth. The cutter teeth are thus axially offset. The tip shroud can be initially manufactured with this shape or may be modified from a used tip shroud having, for example, opposing cutter teeth near a leading edge of a body of the tip shroud. Various tip shroud surface profiles, which are expressed in terms of Cartesian coordinates, are also provided.

摘要： A coupling for a turbomachine, including a first and a second disc attached along an axis, and extending in majority respectively from a first and from a second side of a median plane normal to the axis, the first and the second discs being provided respectively with first and second teeth mutually engaging through the median plane to form a curvic connection. Several first teeth each include a first protuberance jutting out towards the axis while extending from the second side; several second teeth each include a second protuberance jutting out towards the axis of rotation while extending from the first side; the first protuberances are spaced apart from the second protuberances along the axis; at least one blocking member is brought to be supported against the first and second protuberances to block axially the first element relatively to the second element.
