Understanding the performance of materials under rolling contact conditions is crucial in the fields of materials science and engineering. Whether it is bearings, gears, or rail transit wheels and rails, these critical components are subjected to complex rolling contact stresses. As a professional testing equipment, the Pinkui TE72 double roll testing machine can simulate pure rolling or sliding rolling motion conditions, providing reliable data support for material wear and rolling contact fatigue research. Today, let's talk about the wide application of this testing machine in various industries, and how it helps engineers and researchers solve practical problems.

　　The working principle and technical characteristics of TE72 double roll testing machine

The TE72 double roll testing machine adopts a 'suspended' roller design, with the testing roller installed at the end of the testing spindle of the testing machine, instead of using a fully suspended mode. The main advantage of this design is that the test roller is easy to install, and when disassembling the test roller, the bearing can be removed without removing it. The testing machine is equipped with two motors, one for power input and the other for absorbing transmitted power. By adjusting the main and auxiliary drive speeds separately, the desired sliding ratio can be obtained.

In terms of technical parameters, the load range of TE72 is 20N-8KN, the rotational speed is 30-6000 rpm, the slip to roll ratio can reach 0-100%, the roller diameter range is 100-200mm, and the lubricating oil temperature is controlled from room temperature to 150 ℃. These broad parameter ranges enable it to simulate various practical operating conditions.

　Application in Materials Science Research

In the field of materials science, the TE72 double roll testing machine is an important tool for studying the frictional properties of materials. It can be used to study the wear and rolling contact fatigue performance of materials under different oil temperatures, speeds, and loads under pure rolling or sliding motion conditions. After the roller axle box is electrically insulated, the contact resistance can also be measured, providing more dimensional data for the study of material surface properties.
