Tooth Material Reciprocating Friction Testing Machines

1. Product introduction

The test machine is mainly used to determine the frictional properties of slide rails and specific metals at approximate PV values. In addition, the machine can also be used to evaluate the friction and wear performance of lubricants, metals, plastics, coatings, rubber, ceramics and other materials under the condition of high linear velocity. The friction sub-form is mainly point and surface, and the surface contact friction.

All data is recorded by the computer for reference and printing, and the data can be converted to Excel format.

3. Structure principle of testing machine

1. Main technical requirements and satisfaction: (horizontal motion assembly selection)

In order to meet the technical requirements of 2, the product is intended to adopt the following scheme

3.1 The testing machine is composed of normal loading system, horizontal lever, torque force measuring system, temperature control system, cooling and lubrication device, electrical control cabinet and computer real-time data acquisition and control system (including software);

The main body of the testing machine is mainly composed of the main body frame, horizontal frame, normal spindle and its driving system, test force application device, friction torque and displacement high-precision sensing and measuring system, test force measurement and friction temperature measurement system, etc. The normal loading system of the testing machine adopts lever + weight, which has high accuracy and good reliability. Horizontal loading system using linear motor as the loading system, high control accuracy, corresponding fast, the host frame using larger quality cast iron, high natural frequency, shock absorption and seismic performance is good, the box seat is also the use of iron parts after CNC boring the electric spindle firmly locked in the box seat, which can improve the stability of loading work.

3.2 The function of the cooling and lubrication device is mainly to cool and lubricate the actuator so that the actuator can work stably and reliably for a long time. (Suitable for oil testing)

3.3 The computer real-time data acquisition and data processing control system is an intelligent system with the specially prepared control software to manually set, collect, monitor and output the test parameters, which can avoid the artificial influence of the test results and improve the accuracy of the test results.

3.5 The measurement of friction force adopts the high-precision force sensor of American Shiquan Company;

3.6 Under the condition of full lubrication and cooling, the product can fully meet the technical requirements of continuous operation for 1 hour.

3.7 This product can be tested on "pin-disk", "ring-disk", "ring-block" and other friction pairs, and can work under dry friction and oil lubrication; The form and size of the friction pair can be designed according to user requirements, easy to operate, easy to load and unload samples, and attached special tools.

3.8 The test temperature was measured by infrared non-contact thermometry produced by Chinese Academy of Sciences.

3.9 According to technical requirements, real-time acquisition and processing of test parameters such as friction torque, load fluctuation and friction temperature rise generated during test operation are carried out through intelligent instruments and specially prepared computer software, and corresponding test curves are given. Test data can be saved and converted into Excel tables for reference and printable output.
