Underlying Mechanisms

Innenverzahnungen, die aufgrund der Elektromobilität zunehmend im Fokus stehen, lassen sich mithilfe des Wälzschälens produktiv herstellen. Um diese Produktivität weiter zu steigern, müssen die wirkenden Verschleißmechanismen untersucht und verstanden werden. Der Beitrag behandelt die experimentelle Temperaturuntersuchung des Wälzschälens mit anschließender Modellierung der Wärmeverteilung, welche als erster Schritt zum Mechanismenverständnis angesehen werden kann.   Internal gears, which are increasingly in focus due to electromobility, can be manufactured productively with the help of power skiving. In order to further increase the productivity, the wear mechanisms have to be investigated and understood. This paper discusses the experimental temperature analysis of power skiving by subsequently modelling the heat distribution. This process can be seen as a first step towards understanding the underlying mechanisms.

Flank Face

An analytical temperature distribution along the cutting edge and on the flank face of a drill is obtained using Tsueda’s and Loewen and Shaw’s equations after modifications. Experimental temperature distributions are also investigated and the effects of a pilot hole and the heat sink are evaluated. Agreement between the analytical and experimental results is fairly close except near the chisel edge and near the drill periphery. The use of workpieces containing a pilot hole provides a method to account for the discrepancy between the analytical solution and the experimental results near the chisel edge while some explanation is offered to describe the discrepancy near the drill periphery.

Temperature Distributions

Transient internal temperature distributions of vaporizing droplets have been carefully measured, using fine thermocouples at 1 atm. and 1000 K. Droplet diameters are fixed at 2000 ± 50 μm with Reynolds numbers being 17, 60 or 100. Fuels tested are JP-10, n-decane and JP-10 thickened with polystyrene. The effects of Reynolds number and liquid viscosity on internal temperature distribution and heating mechanism have been examined. Experimental results indicate that liquid viscosity or circulation intensity strongly affects the temperature distribution and heating mechanism. In contrast, the temperature distributions associated with the three different Reynolds numbers have shown little difference for both low- and high-viscosity cases. For the low-viscosity JP-10 droplets at Reynolds numbers up to 100, where the vortex model of Sirignano and coworkers (Prakash & Sirignano 1978; Tong & Sirignano 1983) has been claimed to be applicable, the vortex model appears qualitatively correct but quantitatively inaccurate. Physical reasons for the deviation have been discussed. Solutions of the full Navier-Stokes equations appear to accord better with the experimental temperature distributions. Circulative heat transport decreases progressively as liquid viscosity increases. A semi-empirical effective conductivity model for high-viscosity cases yields a very good simulation of the experimental temperature distributions at all the Reynolds numbers when proper effective conductivity factors are chosen. A discussion on internal droplet dynamics and heating mechanisms in physical terms has been provided.
