GT4000 - Mine gear reducer Test system - Main features

01 Functional Modularization

All the platform building is modular in function, and the platform combination is built in back-to-back mode. In the form of module combination, the test system is concentrated in one. Customers can increase or decrease the test modules according to the different test objects.

02 Advanced means of measurement

Advanced real-time measurement and control system is adopted, including input electrical parameters test, rotational speed torque test, etc. The sampling rate of torque and rotational speed is up to 1000Hz, which meets the requirements of high precision and rapid response of the test system. Moreover, transient data and eigenvalue data are provided to facilitate the comprehensive analysis of test process data by software in the later stage.

The test items are complete

According to the test requirements stipulated by national standards, the test items can be increased or decreased according to the configuration module, which can meet the test items for various types of tests

04 Driving system

The induction motor is used as the driving input of the system, which improves the dynamic response characteristics of the system's torque and speed and provides the measuring range and accuracy, improves the driving performance (positive/reverse), reduces the response time of loading, and can load any load curve and highly simulate the real-time operation of the gearbox.

05 Loading system

Asynchronous motor is used as the system load, according to the characteristics of the tested parts, high-precision torque and speed sensors are used to improve the data dynamic response adoption rate. Vector /DTC mode is used to load the system, which can be loaded according to the required high-speed dynamic loading characteristics, so as to highly simulate the real-time operation condition of the transmission output.

06 Humanized design

Adopt professional gearbox test bench, fixture has fast clamping function, and convenient loading and unloading, can adapt to different gearbox installation, system operation recommended to use the cabinet + computer desk control mode, can complete the unit set complete all test operation layout.

08 Customized test software

The test system test software developed by Sichuan Chengbang software research and development team categorizes the software interface and process according to the national standard test items to reduce repeated tests and greatly improve the work efficiency of test personnel. It also has the functions of real-time curve drawing, transient value capture, trend curve drawing and analysis, multi-parameter combination display, qualification determination, report export and so on.
