Non-Newtonian effects on the coastdown phenomenon of hydrodynamic journal bearings
D. Sheeja,B.S. Prabhu +1 more
TL;DR: In this paper, the behavior of a rotating system after its power supply is cut off is called the coastdown phenomenon, and an experimental investigation was carried out on a rotor rig with a single rotor.

Development of low cost instrumentation to monitor coasting-down time of rotating shaft
TL;DR: The development of a low cost on-line instrumentation to achieve condition monitoring technique of coast-down time is discussed and it is envisaged that, the availability of such affordable instrumentation may give the much needed thrust to researchers for further refinement of this technique.

Wear Characteristics of Plain Hydrodynamic Journal Bearings During Repeated Starting and Stopping
TL;DR: In this paper, the onset and development of wear in plain hydrodynamic journal bearings under repeated cycles of starting and stopping has been studied experimentally and it was found that the wear caused easily discernable but localized changes in diametral clearance, surface finish, and roundness of the bearing's bore.

The Behavior of Plain Hydrodynamic Journal Bearings During Starting and Stopping
TL;DR: In this article, the behavior of plain, hydrodynamic journal bearings during starting and stopping under a steady load was investigated and the starting behavior indicated that a rapid buildup of hydrodynamynamic forces occurred in all cases.

Coastdown Time as a Mechanical Condition Indicator for Vertical Axis Motors with Grease-Lubricated Ball Bearings
T. L. Daugherty,R. J. Craig +1 more
TL;DR: In this article, a technique was presented to assess the mechanical condition of vertical axis electric motors equipped with grease-lubricated ball bearings by comparing observed and predicted rotor coastdown times.
