This paper presents a model able of predicting the working temperature of the hydraulic fluid in the case volume and outlet port of axial piston machines. For the first time the working temperature is estimated accounting for the mechanical losses associated with the viscous flow in the lubricating interfaces and the churning motion of the oil in the machine casing; which are calculated in the model. The paper illustrates a thorough comparison between the calculated and the measured case and outlet port temperature for a wide range of operating conditions

Keywords: Axial piston machines; Heat transfer; Churning losses; Case temperature
