Rotating machines are widely used as components of various industries around the world, and its normal operation rotating is important. Thus, condition monitoring fault diagnosis have considerable attention in recent years. Industrial statistics illustrate that 40% total large machine breakdowns happened due to broken bearings, while for small machines, analogous number reaches up 90%. This stu...

This paper presents the concept of Multi-Function Operating Machine mainly carried out for production based industries. Industries are basically meant for Production of useful goods and services at low production cost, machinery cost and low inventory cost. Today in this world every task have been made quicker and fast due to technology advancement but this advancement also demands huge investm...

Acoustic Emission (AE) is being extensively used as a Non Destructive Technique (NDT) for diagnosis of rotating components. The main theory behind this diagnosis is that while rotation, acoustic energy level of defective portion in rotating element is different. In the present study a signal processing technique is proposed to identify the variation in acoustic signal and results are verified f...

Abstract In view of the problems such as difficulty in and high cost vibration signal collection rotating mechanical shaft, this paper proposes a low-cost, fast, stable reliable hydraulic turbine wheel online monitoring scheme specially designed to imbalance dynamic balance counterweight shaft. Three high-frequency wireless acceleration sensors are installed on shaft monitor signals three direc...

Fatigue evaluation is one of the most concerning issue in the design of mechanical parts subject to alternative forces. Fatigue life estimation is more complicated when loads act on different axes. This paper shows the stress analysis result of the steel shaft of a high-speed microgenerator rotor with 47750 rpm and 100kW which has been carried out with analytical stress formulation. The shaft i...

Corrosion is one of the major problems in the industry especially on machinery since it weakens the structure of the machinery part and causes the mechanical failure. This will stop the production and increase the maintenance cost. In this study, the corrosion behaviour of gas nitriding on a screw press machine shaft made from AISI 4140 steel was investigated. Pitting corrosion was identified a...

The torque measurement usually comes from strain gauges bonded on a shaft. The main concern in this measurement is due to the fact that these gauges are also rotating and the integration of electronic on rotating parts is definitely a blocking point. To overcome these limitations, the architecture of our device is mainly composed of two targets, two position sensors, a proof body and a compact ...

There will be presented a model of a passive magnetic bearing. The model uses the ring with molecular current as a source of external magnetic field (the unmovable magnet mounts in a case of machine). The next ring with molecular current moves in external field generated by unmovable ring (the magnet connects with the shaft of machine). The density of magnetic field is obtained from the Biota-S...

The aim of this study was to determine how shaft length affects golf driving performance. A range of drivers with lengths between 1.168 m and 1.270 m, representing lengths close to the 1.219 m limit imposed by R&A Rules Limited (2008), were assembled and evaluated. Clubhead and ball launch conditions and drive distance and accuracy were determined for seven category 1 golfers (handicaps 0.21 +/...

In this paper, an analysis of electromagnetic–mechanical characteristics according to the shaft materials a permanent magnet synchronous motor was performed. general, electric rotating at high speed uses various materials, considering mechanical rigidity and electromagnetic characteristics. However, because material has significant influence on performance non-magnetic magnetic performed shaft....
