Drive Characteristics of Viscous Oil Film Considering Temperature Effect

Abstract

Taking account of temperature and the effect of pressure difference and inertia force on oil film, the analytic solutions for pressure, radial velocity, and transferred torque were derived. The results show that considering the effect of temperature, the pressure reduces at the same radius and inertia force makes the pressure decrease. Compared with the pressure decrease caused by the inertia force, the radial velocity caused by the pressure difference is very small and can even be neglected. As the rotational velocity difference increases, the transferred torque also increases. Meanwhile, the transferred torque reduces when considering the effect of temperature.
