Stand for Measuring Temperatures of the Main Gears of Automobile Differential

Abstract

This paper deals with the design of a universal stand for measuring of the temperature of the main gear of automobile differential and other operation parameters of light automobile gearboxes. The stand is designed for loading of gearboxes in almost real operating conditions. The stand can be used for measurements of main operating parameters of a gearbox but the temperature and thermal parameters of gearbox parts are most important. Emphasis is placed on the measurement of temperature near surfaces of gear teeth. During the measurements on this stand, it is possible to have realistic operating conditions as during real performance of automobile gearbox: the main operation parameters are real mounting of gearbox (real mounting rigidity) and real drive by combustion engine (irregularity of rotation). The goal of this paper is a short conceptual study of an easy stand for measuring temperatures of gears and other operation parameters of automobile gearbox operating in almost realistic conditions.
