Abstract:

Many model test systems are used to determine such as friction coefficient, wear and lubrication the tribological properties of materials under different operating conditions. In this paper, the design and manufacturing of the Pin on Disk wear test apparatus (PDATD)is aimed with reference to ASTM G-99 standards. Care has been taken to ensure that parameters such as different lubrication conditions, load, speed, and different oil temperatures can be adjusted in the test setup. The loading arm is designed to be adjustable so that the load applied in the experimental setup affects the test sample with the same load intensity. In the loading arm mechanism, a rolling bearing and appropriate spaced fit classes are selected to allow the arm to move freely. Finite element and analytical method analyzes were carried out for stress and deformation changes in the loading arm. Gripping and screw connections were used on the disk so that the test samples could be easily mounted. It is possible to use both pin and spherical elements as counter surface elements in the PDATD. Thermocouples suitable for temperature change in the opposite element and temperature measurement under oily test conditions were mounted on the test rig. In addition, in the study, the current values of the drive motor that enables the rotation of the disk were added to the electronic card connection required for measurement, and its relationship with the friction force was tried to be studied.
