600kW One-to-One Forced air cooling Gearbox and Axle Performance Testing and Reliability Testing Bench

600kW One-to-One Forced air cooling Gearbox and Axle Performance Testing and Reliability Testing Bench

The gearbox performance test bench is mainly used to complete the performance test and reliability test of the transmission, drive axle, etc., and can meet the test requirements of the test piece such as efficiency test, dynamic test, performance test, reliability test, etc. The gearbox durability test bench is mainly composed of the input end dynamometer system (drive and load), the output end dynamometer system (load and drive), the feedback variable frequency inverter system, the control system, the data acquisition system, the bench mechanical system, the oil station system, the video monitoring system, etc.

1. 600kW One-to-One Forced air cooling Gearbox and Axle Performance Testing and Reliability Testing Bench Components

• Electric dynamometer:

The electric dynamometer is used as a loading/dragging device for the motor to load/drag the transmission; the electric dynamometer is mainly composed of an AC motor host, a torque flange, an electric dynamometer mounting base, etc. The motor of the electric dynamometer uses SSCD series high-torque products; a torque measuring device is installed on the electric dynamometer for torque measurement; at the same time, an encoder is installed on the electric dynamometer for speed measurement.

• Variable frequency inverter system:

The DTC series frequency conversion control system is used to control the electric dynamometer; the system operates in four quadrants to control the electric dynamometer for loading. The electric energy generated after loading is fed back to the DC bus through the variable frequency inverter system to drive the electric dynamometer.

• XLP2000 control system and control software:

Our company's XLP2000 numerical control system is used for the overall control of the test bench; the XLP2000 control system communicates with the variable frequency inverter system through the bus to complete the setting and control of each working condition of the test bench; the XLP2000 control system receives various parameters collected by the system through the CAN bus, and at the same time the XLP2000 control system integrates external auxiliary equipment, centralizes communication and control; the entire test process can be completed automatically.

• Data Acquisition System:

Equipped with corresponding temperature sensors and temperature acquisition modules, it is used to collect parameters such as the temperature of each part and the temperature of the lubricating oil, and upload the collected data to the XLP2000 control system through the bus to realize data display, recording and processing.

• Coupling and protective cover:

A universal joint transmission shaft is used to connect the transmission shaft system; a protective cover is installed on the upper part of the rotating parts such as the coupling for protection. The coupling is connected to the tested transmission through the tooling to complete the connection of the transmission system of the entire test bench.

• Lubricating oil station

This solution uses the SLE-2120G lubricating oil station to provide constant pressure, constant flow, and constant temperature lubrication for the UUT. The device uses Siemens PLC as the main control unit, which can meet the lubricating oil supply under different setting conditions;

• Adjustable transmission bracket

The adjustable transmission bracket is connected to the transmission through a special connector to form a whole. The height of the transmission can be adjusted up and down by adjusting the lifting screw on the mounting bracket, thereby achieving three-dimensional adjustability of the transmission support; a special adapter tool is installed on the transmission bracket to fix the test piece.

• Cast iron plate

The cast iron plate in this solution is a plane reference carrier made of high-strength cast iron HT250, which has the characteristics of reliable accuracy, stable use and convenient transportation.

• Monitoring system

The monitoring system is equipped with a high-definition night vision camera, a video recorder and an LCD display, which can monitor the product status in real time during product testing.

2. 600kW One-to-One Forced air cooling Gearbox and Axle Performance Testing and Reliability Testing Bench Working Principle

The drive system outputs power to drive the gearbox according to the preset working conditions, the load system simulates the actual load, and the data acquisition system transmits parameters to the control system in real time, and the control system dynamically adjusts the drive and load accordingly. Video monitoring and sealing testing work together, and after the test, the transmission efficiency, load-bearing capacity and other indicators are calculated through data analysis to complete the performance evaluation. ​
