Demag hollow shaft wheel set is a drive system that highly integrates the drive motor, reducer, and travel wheel. It adopts a hollow shaft connection structure - the motor output shaft is directly inserted into the hollow shaft in the reducer or wheel block, and a keyless connection is achieved through devices such as tensioning discs. This structure replaces the traditional complex transmission forms such as couplings and keyways, simplifies installation and improves operating stability. Due to its compact structure, high transmission efficiency, and convenient installation, it is widely used in rail transport vehicles, overhead cranes, automated conveying platforms and other fields, and is one of the core components for improving the stability of rail travel systems.
Why choose a hollow shaft structure?
1. Simple structure and convenient installation
The hollow shaft structure eliminates intermediate transmission components such as couplings and bearing seats, reduces failure points, reduces installation complexity, and facilitates maintenance and replacement.
2. Higher transmission efficiency
The hollow shaft connection structure has good rigidity, high torque transmission efficiency, low operating vibration, and low noise, and is especially suitable for automated rail systems that require precise operation.
3. Save installation space
Since the motor can be directly inserted into the wheel box, the entire drive unit is more compact and adapts to narrow installation spaces. It is an ideal choice for low-profile equipment such as rail transport vehicles, AGV/RGV, etc.
4. High adaptability
It can be applied to motors of various brands (such as SEW, ABB, Nord), with good versatility and flexibility.
Technical advantages of DEMAG travel wheel block system
Demag wheel set combines high-precision processing with modular design concepts, and has the following significant advantages:
• High-strength cast steel structure, strong load-bearing capacity, impact resistance, and long life;
• Maintenance-free bearing system, adaptable to heavy load and high-frequency operation scenarios;
• Modular wheel set design, easy to replace and expand the system quickly;
• Surface hardening or polyurethane rubber wheels are optional to meet the requirements of different ground materials (rails, concrete floors, etc.);
• With the variable frequency drive system, it runs more smoothly and achieves stepless speed regulation.
• It can be customized according to the size of the transport platform, running speed, and track gauge requirements.
