H.Yanar,M.Demirtas and G.Purcek, A New Multi-Functional Tribometer: Application of Block-on-Ring Test Module , TurkeyTRIB'18, 2nd International Conference On Tribology,18-20 April,2018 in Istanbul, TURKEY
Abstract:This paper presents a new-designed tribometer (UTS TRIBOMETER T30M) with block-on-ring test module for especially characterizing the tribological behaviors of materials of sliding bearing used in applicationssuch as connecting rods and cranks in internal combustion engines, steam and water turbines, air compressors and centrifugal pumps. This tribometer with block-on-ring module allows users to make tribological tests in both dry and lubricating conditions according to ASTM-G77-98 standards at temperatures starting from room temperature up to 150 °C with an accuracy of 2 °C by adapting a plate type heater. Themodule can be easily adapted to the tribometer and removed after the tests, and it has a well-designed special arm for measuring the friction force.The friction force is precisely measured by inductive sensors placed on thisarm. The tribometer has its own software called Turquoise which allows users to control the experimental parameters such as applied load, rotational speed (rpm) and diameter of the shaft, sliding distance and test duration. The friction force obtained during the test are presented graphically via this software. The module simulates different configurations such as half-bearing and specimens with conform or non-conform contact surfaces.In addition, itallows user to leakage test of oil seal in lubricating conditionsvia the specially designed holder according to ISO standards.Furthermore, this tribometer simulates the different contact pin/ball-on-disk and test types such as circular(ASTM-G99) and linear reciprocating (ASTM G133). Tribometer can be operated with or without lubricant according to appropriate standards in all modules. Also, it is possible to adapt an environmental chamber to the tribometer in order to do the tests in the different atmospheric conditions. Keywords:Multifunctional tribometer, block-on-ring module, bearings.
