I.Application
This testing machine primarily uses rolling friction to evaluate the tribological properties of coatings, plastics, non-metals, metals, powder metallurgy, ceramics, and other engineering materials, as well as their surface-modified materials, under specified test conditions. It can conduct tests at room temperature under various conditions, including oil-free and oil-immersion lubrication, and with variations in load, speed, time, friction pair materials, surface roughness, and hardness. It can be used to measure parameters such as material temperature rise, coefficient of friction, friction force, and friction torque. It is equipped with various friction pairs, including end faces and pin discs. Users can also develop other types of friction pairs according to the machine's friction pair mounting interface dimensions for research on the principles of friction and wear, as well as experimental methods.
Meets the follow testing standards:
*ASTM D3702-94(2020) Thrust Washer Wear Test
*ASTM G99-17 Pin/Disc Wear Test Method
*ASTM D6425/D7217 (SRV Test)
*ISO 20623 (Four-Ball Test)
*GB/T12583 Determination of Extreme Pressure Properties of Lubricants (Four-Ball Test)
*GB3142 Determination of Carrying Capacity of Lubricants (Four-Ball Test)
*SH/T0189 Determination of Anti-Wear Properties of Lubricating Oils (Four-Ball Test)
*SH/T0202 Determination of Extreme Pressure Properties of Lubricating Greases (Four-Ball Test) and other national standards.
Features
The machine consists of a base and frame, a spindle and its AC servo drive system, a friction pair disk and sample clamping device, a closed-loop servo application system for the test force, electronic measurement systems for various test parameters, a computer and data acquisition boards, and dedicated control software. The spindle is driven by an AC servo motor and its control system. This system can achieve constant torque output across its entire speed range and operate smoothly at extremely low speeds, thus enabling stepless speed regulation of the spindle over a wide range to meet the needs of different researchers.
The test force is applied using a closed-loop servo system. Its magnitude is set by the operator on the computer interface and automatically controlled to maintain a constant force. The applied force is smooth, reliable, and constant, thus avoiding the influence of test force fluctuations on the test results. This system is implemented by a servo system and a speed control system. The machine's spindle speed, revolutions (test cycle), test force, friction torque, friction coefficient, friction force, friction pair temperature, test time, and other parameters are all controlled by a computer. Test data is collected in real time and corresponding test curves (such as temperature-time curves, friction force-time curves, etc.) can be plotted. The data can be stored, retrieved, and printed out at will. The data is authentic and reliable, and is not affected by human factors.
