... interference and acoustic emission (AE) were employed as experimental methods to investigate simple sliding point contact intermittent motion. The lubrication state transition of full film-starvation-wear in the contact area was observed and the experimental results confirmed the correctness...

...Surojit Poddar; N. Tandon This present article evaluates the state of starvation in a journal bearing using acoustic emission (AE) and vibration measurement techniques. A journal bearing requires a constant supply of oil in an adequate amount to develop a hydrodynamic film, thick enough to separate...

.... 14 07 2012 21 06 2013 This paper deals with vibration and acoustic emission (AE) measurements evaluating the separation of the balls and raceways with lubricating film in a linear-guideway–type recirculating ball bearing (linear bearing) under grease lubrication. In the experiments...

...Hiroyuki Ohta; Shinya Hayashi; Soichiro Kato; Yutaka Igarashi This paper deals with effects of grease types on vibrations and acoustic emissions (AEs) of linear-guideway type recirculating ball bearings with a millimeter-sized artificial defect in the carriage. First, the vibration and AE of one...

...Hiroyuki Ohta; Kazuya Matsuura; Soichiro Kato; Yutaka Igarashi This paper deals with vibrations and acoustic emissions (AEs) of linear-guideway type recirculating ball bearings with a millimeter-sized artificial defect in the carriage. The vibration and AE of one normal bearing without a defect...

...R. I. Raja Hamzah; Khamis R. Al-Balushi; D. Mba This paper presents experimental findings on the generation of acoustic emission (AE) from operational spur and helical gears as a function of specific film thickness ( λ ) . The latter was varied while the gears were operating by spraying liquid...

...R. I. Raja Hamzah; D. Mba This paper presents experimental results correlating acoustic emission (AE) activity and the specific film thickness ( λ ) for operational spur gears. This relationship was established by spraying liquid nitrogen onto a rotating gear wheel, thereby reducing its operating...

...Norio Tagawa; Noritaka Yoshioka; Atsunobu Mori This paper describes the effect of ultra-thin liquid lubricant films on air bearing dynamics and flyability of nano-spacing flying head sliders in hard disk drives. The dynamics of a slider was monitored using Acoustic Emission (AE) and Laser Doppler...
