Analysis on Oil Film Temperature Field of Hydro-Viscous Variable Speed Clutch

Abstract:

According to the structure and working principle of hydro-viscous variable speed clutch, the energy equation of oil film between the friction discs is derived. After solving the pressure and velocity of oil film, the analytic solution of energy equation and the oil film temperature distribution is acquired. It is shown that the temperature rise of oil film is proportional to the square of angular speed difference and the forth power of friction disc radius, and is inversely proportional to the flow flux and the film thickness. The above conclusions have important significance to reasonably choose lubricant oil and the friction disc material, and ensure the normal work of hydro-viscous variable speed clutch.
