This paper is concerned with torsional vibration in the design, development, and fault diagnosis and correction of machine systems. The physical behavior of torsional vibrations in shafting systems and sources of torsional ...

High speed gear drives can be reliable if all the factors influencing their design, application, and operation are considered during the design stages. This paper will discuss the parameters used by gear engineers and the ...

The purpose of this paper is to present some user guidelines for the selection, operation, and maintenance of mechanical end face seals in chemical, petrochemical, and petroleum operations. Though the exact seal requirements ...

Steam turbines employed as mechanical drivers require special design features. The problems confronting a turbine designer arc blade and shaft vibrations, bending and centrifugal stresses, torsional analyses as well as ...

This paper describes and economically justifies one major oil company's utilization of a total Integrated Mechanical Inspection Program as an alternative to high maintenance costs and reduced plant productivity.

The creep properties of gas turbine blades will deteriorate with prolonged service exposure. This deterioration is primarily due to internal microstructural changes and the formation of creep voids or cavitation. Development ...

The presentation will cover fluid film bearing fundamental theory and design criteria. Since the subject is extensive, the design portion will be restricted to hydrodynamic (self-acting) bearing mode using liquid lubricants. ...

This paper deals with the development of the turbomachinery industry in Japan for the past five years. The machinery discussed includes gas turbines, gas expanders, turbochargers, steam turbines, compressors, blowers, and ...

The problem of steam turbine rotor whirling following uprating of a stable design and the measures taken to define the problem and implement a solution are described. Nearly identical units installed at several of Union ...
