System Introduction
The drive shaft mechanical seal test system (also known as "square machine") developed by TMC Solutions Automotive Testing Factory includes electric drive system, mechanical seal loading system and hydraulic power source, which can complete universal joint, spline wear fatigue test and drive shaft fatigue life test .
This year, TMC Solutions Automotive Testing Factory has carried out a comprehensive technical upgrade to the mechanical seal test system of the drive shaft, optimized the design of the hydraulic loader, adopted the company's latest research and development of hydrostatic bearing technology, and improved the sprocket wear test drive device, which can achieve highly dynamic motion process.
The newly upgraded system is driven by an AC variable frequency motor and loaded by a hydraulic loader. The advanced test software can accurately simulate the working conditions of the drive shaft on the vehicle through parameter setting. And the loading accuracy is high, and the durability test of four specimens can be carried out at the same time.
Test Item
Universal joint wear fatigue test
Spline wear fatigue test
Fatigue life test of drive shaft assembly
System Features
High loading accuracy: using non-contact torque sensor, high loading accuracy and long service life.
Accurate speed regulation: The motor speed regulation is smooth, the speed regulation range is large, and the speed control precision is high.
Wide test range and high efficiency: covering the test requirements of passenger car half shafts, heavy truck drive shafts and special drive shafts, forming a series of products; the system adopts servo closed-loop control, and the loading waveform can be freely set according to the test requirements; The software system program has a high degree of openness and can be combined with multiple parameters according to the experimental requirements.
Good vibration resistance and durability: It adopts linear sliding structure with low friction, which is suitable for high-speed reciprocating motion and is resistant to vibration; it adopts special hydrostatic support for loading oil cylinder, which can resist strong side load.
Quiet: The hydraulic oil source is specially designed to control the test sound below 75dB.
Energy saving: The hydraulic system can adapt to variable output, reduce system energy consumption, and comprehensively save more than 60% of energy.
Safety: It has complete safety detection, alarm and protection functions (infrared temperature detection, pressure detection, liquid level detection, blockage alarm, displacement detection, mechanical limit, electrical limit, etc.); the protective cover has high strength and good safety performance.
