15 Ton Wheel Excavator Axle
1. The drive axle is configured with a two - stage deceleration transmission arrangement.
2. The main reducer makes use of equal - height tooth epicycloid bevel gear. This kind of gear is characterized by high strength, high transmission efficiency, and it also operates with low noise.
3. The NGW - type planetary gear transmission is structured in a rational and compact way.
4. The axle is crafted from ductile iron casting, endowing it with excellent rigidity and a large load - bearing capacity.
5. A closed multi - disc wet brake is employed for braking. It operates hydraulically and releases by spring force. The braking performance is stable, ensuring safety and reliability.
6. It is applicable to 15 - ton wheel excavators.
Introduction：
The 15-ton wheeled excavator's axle features a two-stage reduction drive structure. The axle housing is made of cast iron. The main reduction mechanism uses cycloid bevel gears, and the wheel-side reduction mechanism uses an NGW-type planetary transmission mechanism. Braking is performed using a closed wet disc brake system, ensuring safety and reliability.
