Contact stiffness and damping of spiral bevel gears under transient mixed lubrication conditions
Friction, 2021 Existing studies primarily focus on stiffness and damping under full-film lubrication or dry contact conditions. However, most lubricated transmission components operate in the mixed lubrication region, indicating that both the asperity contact and film ...

Lubrication properties of nylon mixed with lubricants.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1987 Plastics are used widely as sliding parts. In order to investigate the effect of the varied lubricants mixed in the nylon rollers, experimental equipment was designed and manufactured. In the experiment on the friction of the nylon roller, a nylon roller was rotated contacting with a steel roller in the same direction.
