Main reducer (differential) assembly test system

Main reducer (differential) assembly test bench is used for main reducer and differential assembly series product development tests and corresponding product performance and life span inspections. . Main functional features:
On the basis of fully meeting the relevant test requirements, this plan also fully considers the technological advancement, accuracy, reliability, and ease of maintenance of the equipment.
Energy-efficient: Using advanced energy feedback technology to reduce equipment energy consumption.
Using high-precision measurement sensors and high-precision actuators to ensure the accuracy of measurement and control.
The equipment structure and material selection fully guarantee the test intensity requirements. Key components are made of world-class brand products, and have complete fault status monitoring and automatic protection to ensure safe and reliable operation of the equipment.
The use of highly integrated and modular drive units, operating units, and test units makes the entire system a combination of modules, making the system easier to use, interchange, manage, and maintain.
The control part of the test bench is divided into manual control and computer control. In both control modes, the functions of the entire test bench can be realized
The test bench has emergency stop function and automatic monitoring function. In the automatic monitoring state When the parameters monitored by the test bench exceed the set value, the test bench will automatically stop and have a manual emergency stop button function. For fault alarms, the diagnosis results can be displayed on the control cabinet or computer, and the troubleshooting methods of common faults are introduced in the instructions

Scope of technical application

Technical Performance
The control part of the test bench is designed following the modular design principle, making the control part of the test bench simple, reliable and highly flexible
The test bench can implement program loading, within limited The input, output speed, torque, speed difference between the two wheels, test temperature °C, current gear position of the differential and other test parameters of the differential can be set arbitrarily within the range, and the entire test process can be automatically completed according to the set test program, and Real-time monitoring and recording of test data and graphics.
The control program for differential test can be compiled and modified separately, and the parameter settings are easy to understand. Control and monitoring data (such as speed r, torque, speed difference r, temperature ℃) can be detected, displayed, recorded in real time on the control cabinet and computer, and error prompts can be provided.
The test software should be able to set each test parameter through the user interface, allowing users to customize, store and execute real-time data collection during the test process. The computer screen displays various test data in real time, drawing time-test force, loading torque-locking coefficient and other curves, and fully automatic data processing
The test data can be saved in a variety of file formats and can be imported and downloaded from a variety of software. Processing
A special test result data processing program, through which functions such as data retrieval and printing of completed tests can be realized, and the test data can also be exported to the computer for analysis of test data, etc.
The data acquisition and automatic control systems can operate continuously for hours and hours.
The test has a differential test function. The speed difference between the two sides can be adjusted from ~ according to the test requirements
When doing the self-locking differential test, the torque on one and two sides can be measured and the self-locking coefficient curve can be drawn
br/> For ordinary differentials, the torque and speed of the output end can be controlled to ensure the speed difference between the two sides and complete the differential life test.
