...A. Dindar; A. S. Chimanpure; A. Kahraman A tribo-dynamic model of ball bearings is proposed to predict their load-dependent (mechanical) power losses. The model combines (i) a transient, point contact mixed elastohydrodynamic lubrication (EHL) formulation to simulate the mechanics of the load...

...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...

...Shuyun Jiang; Hebing Mao The oil-air lubrication system has been widely used for rolling ball bearing. However, as the rotation speed increases, the temperature rise will increase dramatically, resulting in shortening the service life of the ball bearing. The existing literature has offered...

...Ali Kahirdeh; M. M. Khonsari A method for detection of wear in thrust ball bearings coated with molybdenum disulphide ( MoS 2 ) is presented. It employs an energy feature obtained from time-frequency representation of the vibration signal. Extensive experimental studies are conducted to verify...
