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.

Dissimilar Aluminum Alloys

Microstructural characterization and temperature analysis have been performed in friction stir welding (FSW) of A383 and 5052 dissimilar aluminum alloys. Marked difference in microstructure was observed between joints with different arrangements of materials. The temperature at four points on each side of the joint line was measured during FSW in various conditions. In addition, an analytical model assumed that the work generated by the rotation of the tool led to the work for stirring materials and heat generation of the material and the tool. The temperature of the retreating side (RS) for the joint of the advancing side (AS):A383/RS:5052 was about 50K higher than that of AS, while the temperatures of AS and RS for the joint of AS:5052/RS:A383 were almost the same. The experimental temperature could be calculated reasonably by using the model with assumption of the work for stirring the material.

Air Control

For controlling emergency escaping by a bus driver in the case of air control door cannot be opened normally, the paper presented a multi-manual emergency escaping system of pneumatic bus door. Bus driver and passenger can control doors expediently. The pneumatic circuit of the system and its overall arrangement is discussed. A manual control device with special valve core structure is designed. The working performance of the manual shift directional valve is analyzed. The results indicate that driver and passengers can control the bus doors under the state of abnormal condition via manual control devices in series connection rapidly. Driver and passengers control is without mutual interference. Manual shift directional valves are convenient, reliable and fast.

Effects Of Temperature

This paper presents an overview of thermal and mechanical analysis performed on the tubesheet joint of a 45 inch diameter feed/effluent heat exchanger to determine the effects of temperature on the joint operation. Two methods of analysis are used, a new analytical approach and Finite Element Analysis (FEA). The analysis determined a potential problem with the operation of the joint in the intended service and a method of improvement was proposed. Some pitfalls of the methods of analysis, for both the analytic method and FEA, are presented. The comparison between the analytic approach and FEA clearly outlined the advantages of each method in determining the operability of heat exchanger joints.
