DRS Wheel Block Heavy-Duty Travel Unit 42CrMo Cast Iron

DRS Wheel Block System Heavy-Duty Travel Units with High Load Capacity

1. Powerful driving ability:

Large torque output: The optimized planetary gear reduction mechanism can provide very large output torque to drive heavy equipment to travel smoothly on various road conditions (including ramps).

High power density: The compact structure achieves high power transmission in a limited space.

2. Excellent load-bearing capacity:

Heavy-duty design: The key components such as the housing, axle, and bearings are made of high-strength materials (such as alloy steel) and reinforced design, which can withstand the huge dead weight and working load of the equipment.

Optimized bearing arrangement: Large-sized, high-load-bearing tapered roller bearings or specially designed bearing combinations are used to effectively disperse the load and ensure stable operation of the axle.

3. High reliability and long life:

High-quality materials and manufacturing processes: Key gears are usually made of high-quality alloy steel, which is processed by high-precision processes such as carburizing quenching and grinding. They have extremely high surface hardness and fatigue strength and good wear resistance.

Sturdy box structure: The box is usually made of cast steel or welded steel structure with good rigidity, which can effectively protect the internal gears and bearings and reduce deformation.

Reliable sealing system: It adopts multiple seals (such as skeleton oil seals, labyrinth seals, O-rings) to effectively prevent the intrusion of external pollutants such as water, sand, dust, etc., and prevent the leakage of internal lubricating oil. The protection level usually reaches IP67 or higher, which is particularly suitable for harsh environments such as ports and mines.

Efficient lubrication: It is designed with reasonable lubrication oil channels and sufficient oil storage space to ensure that gears and bearings work in a good lubrication state, reduce wear and extend life. High-performance gear oil is usually used.
