1、 Product introduction:
The ring block friction and wear tester is used to test the friction and wear performance of the sample by means of linear contact sliding friction. Operating principle: the driving part is a standard rotating ring, and the driven part is a fixed rectangular block of standard size. The bearing capacity of lubricant and the friction and wear performance of friction pair materials are evaluated by measuring the width of strip wear mark on the rectangular block of passive test piece under different loads and the friction and friction coefficient between friction pair materials. Under the condition of oil-immersed lubrication, evaluate the lubricating performance of various lubricants, especially applicable to the simulation evaluation of the anti-abrasion performance of the gear oil of medium and high-end vehicles, and can be used for the research on the wear performance of various metal, non-metallic materials and coatings.
The ring block wear tester, also known as Timken friction tester, was developed by Timken from 1935 to 1972 for testing lubricating oil and grease. It is mainly used to test the bearing capacity of lubricating oil and distinguish the extreme pressure performance of lubricating oil. The extreme pressure performance is represented by OK value. It is used to evaluate the friction performance of lubricating oil and grease. The extreme pressure, wear resistance and friction performance test shall comply with GB/T12444, GB/T3960, GB/T11144, ASTM D2782, ASTM D2509, IP 240 and IP 326.
The new ring block testing machine produced by Hengxu adopts a new split structure with novel appearance. The loading load is directly applied by a servomotor through precise deceleration, conversion and buffering to overcome the fluctuation and error of lever loading. The test parameters are set in a unit manner, which is convenient for operation and accurate and reliable test readings. The machine adopts a modular structure design. The computer, software, industrial control module and actuator are combined in an independent control cabinet to reduce the overall vibration of the equipment during fierce friction of the ring block friction pair and complete the control of the entire test process. The test data can be collected in real time and corresponding test curves can be drawn. The test data or curves can be stored, retrieved, printed and output at will.
The advantages of friction and wear equipment of Hengxu Company are analyzed as follows:
1. Loading mode: this type of testing machine is the first servo motor loading machine introduced by our company in the industry, with strong controllability, low failure rate, stable and reliable performance after years of continuous improvement. The double floating bearing technology, gapless guide technology and buffer cross balance technology are all guarantee for accurate and stable test force, reduce system error, and ensure the accuracy of real-time tracking measurement of test force and friction force;
2. Main structure: during the friction test, the impact of vibration of the motor and accessory parts on the abrasion marks shall be minimized. Therefore, we adopt the integral main body, thickened support plate, and Taiwan Dongyuan servo motor to drive the main shaft. The relevant transmission components also adopt imported precision bearings;
3. Electrical part: the equipment adopts independent embedded industrial controller, industrial metal touch screen and acquisition independent analysis module, which can effectively ensure the impact on the performance of the control part when the equipment vibrates at high speed or when the oil film breaks;
4. Control software: generally, real-time acquisition can be realized by software, but we are self-developed special software (for the software transformed from universal material testing machine), and professional test schemes can be established according to different standards.
5. Service team: Adhering to the principle of "innovation and focus" and aiming at "providing high-quality and cutting-edge inspection equipment for the society", we not only produce this type of equipment (enterprises without R&D strength randomly assemble according to drawings), but also have independent technical service departments (over 100 colleges and universities cooperate in research and development of friction and wear tester for many years). Specific problems can be analyzed and solved in real time. At the same time, Hengxu Testing Machine - Research and Exhibition Center invested and constructed by us in the National New Material Industrial Park has been put into operation, providing a solid base for the later R&D and expansion of the company (there are potential safety hazards, quality and service problems in rented plants and unlicensed production enterprises).
