Multi-functional Friction and Wear Testing Machine
I. Equipment Introduction and Application
This equipment features two motion modes, including rotational and reciprocating test modules, which can be easily replaced to meet a wider range of testing requirements.
(1) Rotational Module
The equipment operates in a rotational mode to realize various friction contact forms and lubrication conditions. It is used to simulate friction tests between different tribological pairs, with multiple configurations such as pin-on-disc, end-face friction pair, and ball-on-disc friction pair. It can perform point, line, and surface friction simulation tests.
It is suitable for evaluating the friction and wear performance of materials such as lubricants, metals, coatings, surface coatings, plastics, rubber, and ceramics. It meets the requirements of users in petroleum and chemical industry, machinery, energy, metallurgy, aerospace, and other tribology-related fields for the development and testing of high-end oil and grease products, as well as new material development and process research.
(2) Reciprocating Module
The equipment operates in reciprocating mode, mainly used for friction and wear performance testing of materials and surface coatings.
It adopts an industrial control computer system for real-time monitoring and control of the entire test process. The test force is automatically maintained with constant loading and supports dynamic variable loading (sine wave, triangle wave, square wave, trapezoidal wave), ensuring stable and reliable loading.
It can simulate point, line, and surface contact friction forms under reciprocating motion, enabling measurement of friction force, wear volume, and other parameters under different loads, frequencies, lubrication conditions, and temperatures.
The system can be expanded with corrosion resistance functionality to simulate testing under deep-sea environmental conditions.
II. Structural Overview of the Testing Machine
The testing machine mainly consists of a drive system, load loading system, rotational module, reciprocating module, friction pair clamping mechanism, signal acquisition & processing system, and electrical control system.
2.1 Drive System
The main shaft is driven by a servo motor and servo speed control system. The rated torque of the motor is 5 N·m, with stepless speed regulation and a high-speed accuracy of 1%.
The servo motor power is 1.5 kW, directly connected to the spindle base, ensuring no torque loss. The upper part of the spindle base can be replaced with a concentric or eccentric wheel to achieve rotational or reciprocating motion.
2.2 Load Loading System
The loading system is driven by a stepper motor, transmitting motion via an arc-tooth synchronous belt, pulley system, and precision ball screw, guided by linear guide rails.
It drives the loading seat to move vertically. A linear guide, force sensor, and compression spring are installed on the upper surface of the loading seat. When moving upward, the loading seat contacts the upper specimen holder and compresses the spring, thereby generating the test load between the friction surfaces.
2.3 Reciprocating Module
This module consists of an eccentric adjustment wheel, connecting rod, main shaft rod, linear fixing device, and reciprocating friction pair assembly.
2.4 Rotational Module
This module includes a driving pulley, driven pulley, synchronous belt, rotary spindle base, and rotational friction pair assembly.
2.5 Rotational Friction Pair Mechanism
Custom friction pair configurations can be developed according to customer requirements to expand the testing capability of the machine.

Standard configurations include:
l Ball-on-disc (point contact)
l Pin-on-disc (line contact)
l Flat-on-flat (surface contact)
