A method for balancing a rotating assembly of a gas turbine engine includes removing a stator vane from a section of the gas turbine engine. Removing the stator vane provides access to a rotating assembly of the gas turbine engine. The method further includes at least one of adding, removing...
Rotating automotive, industrial and agricultural machine assemblies are also candidates: brake rotors, pump rotors, combine rotors and cylinders.Turbine Metrology offers an expanding range of industry-leading hardware and software products for gas turbine, jet engine, and high performance automotive ...
The gas-turbine engine110in accordance with FIG. 1 is a generally represented example of a turbomachine where the invention can be used. The engine110is of conventional design and includes in the flow direction, one behind the other, an air inlet111, a fan112rotating inside a casing, an in...
It is now general practice to dynamic balance every turbine wheel and impeller assembly before fitting to the engine. Maintenance engineers, while having a background in the theory of vibrations caused by unbalance, must now know the practical side of dynamic balancing, since it is almost ...
A clothes washing machine is provided with an oscillating washing assembly including a rotating drum capable of being driven at various rotating speeds and provided with a plurality of annular hollow bodies secured to the drum. A plurali... I Haberl,M Trangoni - US 被引量: 39发表: 1999年 ...
According to the loads acted on crankshaft of internal combustion engine and its mathematical simulation based on the continuous beam theory and three moments mechanics, a group of calculating equations and the computer program used for analysing engine balance are derived and exercised with practical ...

In the same way, balancing can be conceptualized as a procedure by which the mass distribution of an armature is verified by measuring the vibration generated while it is rotating at a speed similar to its working speed. If necessary, this is corrected to ensure that the residual unbalance is...
Keywords: rotating devices; defects; shaft bow; diagnosing; balancing 1. Introduction A drastic level of vibration produces noise and reduces machine performance; it diminishes the machine’s service life and reliability and can even result in dangerous difficulties. As a result, many sophisticated co...
Hard disk drives contain a plurality of magnetic heads coupled to rotating disks. The disk pack rotates the disk surfaces in a hard disk drive. Imbalances in the disk pack adversely affect communication to and from the rotating disk surfaces. Therefore, disk packs must be balanced to minimize ...
