· Industrial Appliions Of Optical Shaft Encoders Edmister, Brian W. 00:00:00 The development of the microprocessor and minicomputer for industrial process control has made the optical shaft angle encoder a natural choice for a position feedback transducer. Many of these appliions, however, require the encoder to operate reliably in extremely hostile environments. In .
The Whirling of Shafts Unit, "MEER", is a unit manufactured by EDIBON to demonstrate and determine different modes of oscillation and resonance of shafts with continuous distribution of mass under different conditions.
Whirling of shafts : Whirling of light flexible shaft with an unbalance disk at the centre of its length with and without damping, discussion of the speeds above and below the critical speed, uniform shaft with and without unbalanced masses attached along its length (by Rayleigh Method) for simply supported and fixed ends.

The set up is designed to study the whirling of shafts. The setup consists of a sturdy frame, variable speed motor bearing holders etc. Different bearing can be fitted in bearing block to have different end conditions (i) both end fixed, (ii) one end free and one end fixed etc. A variable speed motor is provided to drive the shaft along with speed control unit as the test is ...
pumps for industrial appliion. twice at the 1st and 2nd Workshop by Acosta et al. [ref. 2, 31. ... The test pump is a singlestage, vertical shaft, centrifugal type. The mechanism of the forced whirling motion is illustrated schematically in fig. 1. The impeller is supported overhung by two selfalignment roller bearings, which are mounted separately on the upper and lower whirl plates, on ...
· As described above, for a shaft in torsion, the shear stress varies from zero at the center of the shaft (the axis) to a maximum at the surface of the shaft. When the surface reaches the elastic limit and begins to yield, the interior will still exhibit elastic behavior for some additional amount of torque. At some point, the applied torque causes the shaft to enter its plastic region, where ...

C) Carbon dioxideWater done clear. D) AmmoniaWater done clear. View Solution play ...
Fig. 3 illustrate a shaft undergoes whirling; in (a), a whirling shaft is shown in its deflected configuration, and in (b), the situation occurring in xy plane is sketched. As the spin speed is equal to the whirl speed, the zone of the cross section of the shaft subjected to tensile stresses (shaded part close to point B) remains always

· The hydrodynamic film forms with shaft rotation, so an appropriate fluid must always be present during operation to keep the bearing and rotor surfaces separated. If the fluid flow is lost or interrupted during operation, the bearing surface will come in contact with the shaft and be damaged. The fluid used in most hydrodynamic bearing appliions is a mineral oil or synthetic lubricant. The ...
Supplied with the apparatus is a set of test shafts of different length and diameter to show how these properties affect whirling and its 'critical speed'. Also supplied is a set of weights to show how concentrated loads affect whirling. One weight has an extra hole to make it an eccentric load. This helps to show the phase difference between the load and the deflection (you need the ...
