Estimating the term…
The present invention relates to an improved rotor balancing system which allows for fine tune onsite adjustment for turbomachinery. The rotor balancing system comprises a rotor element having a row of locating slots and a device for reducing windage effects caused by the locating slots and protruding anti-rotation pins. In a preferred embodiment, the device for reducing windage effects comprises at least one balancing ring which partially or fully covers the locating slots and internal slots for engaging and disengaging that does not protrude outbound of the ring. Each balancing ring is preferably provided with two integrally formed anti-rotation members for engaging the locating slots. Each balancing ring is also preferably provided with a slot in a weighted portion of the ring for receiving a tool for positioning the balancing ring in a desired position. A method for positioning the balancing ring on a rotor element using the slot and the tool is also described herein.
A rotor balancing system for turbomachinery comprising:
A method for positioning a balancing ring on a rotor element comprising the steps of:
A rotor balancing system for turbomachinery comprising:
An improved balancing ring for use in a rotor balancing system comprising a first end, a second end spaced from said first end when said ring is in a relaxed state, a weighted portion, and a slot machined in said weighted portion to receive a tool for facilitating positioning of said ring in a rotor element.
