...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...

... with grease, corn oil, VG100, and VG32 were used to investigate the lubrication characteristics. During the test, temperature was measured in the specimen by a K-type thermocouple to determine the temperature increase induced by heat generation due to plastic deformation. In the present investigation...

...A. K. Pogosian; T. R. Martirosyan The development of new types of high-pressure plastic lubricants using natural minerals is of much importance. The effects of surfactant proportion and the structure of the nanoparticle thickener surface on the tribological properties of the bentonite-based grease...

...Xiaobin Lu; M. M. Khonsari A series of experiments was performed to study the behavior of grease-lubricated journal bearings. The results reveal that an oscillatory bearing undergoes a transition from boundary, to mixed, and to hydrodynamic regime. Another distinct feature is friction hysteresis...

...Xiaobin Lu; M. M. Khonsari A series of experimental results is presented to explore the frictional characteristics of a grease-lubricated journal bearing. Load, grease type, and bushing material are varied to examine their effects on the friction coefficient. The results attest to the existence of...

...S. Kondo; R. S. Sayles; M. J. S. Lowe The paper describes an experimental technique combining optical interferometry and ultrasonic attenuation to measure the bulk modulus (compressibility) and film thickness profiles of oil and grease films entrapped between a stationary steel ball and a sapphire...
