Working principle of a double-drum roller

【文章概要】The use of the loading roller significantly reduces the operator’s workload. The design of the double‑drum roller allows it to be operated more conveniently in the same working environment. However, due to the miniaturization of its components, even minor malfunctions can lead to issues if the machine is not maintained properly. Now, let’s take a look at how the double‑drum roller works!

The use of the loading roller significantly reduces the operator’s workload. The design of the double‑drum roller allows it to be operated more conveniently in the same working environment. However, due to the miniaturization of its components, even minor malfunctions can lead to issues if it is not maintained properly. Now, let’s take a look at how the double‑drum roller works!

In general, when a double-drum roller is operated under overload conditions, the positions of its component particles shift, and the shapes and orientations of the component elements also change. The inability of these components to return to their original states is referred to as plastic deformation.

The plastic deformation of load roller components primarily manifests as bending, torsion, and other forms. After deformation, the compaction machinery is prone to malfunctions such as abnormal noises. When a component, subjected to cyclic loading over an extended period, develops cracks that eventually lead to fracture or pitting, this phenomenon is referred to as fatigue failure. The operating principle of the load roller is as follows:

Fatigue damage in load‑carrying rollers commonly occurs in components subjected to cyclic loading, such as gears, bearings, shafts, springs, and rods. Under the action of cyclic contact stresses, the surface layer hardens, initiating microcracks; subsequently, the pressure generated by lubricant ingress into these cracks promotes crack propagation, ultimately leading to fracture and pitting.

Detailed precautions for common malfunctions of double-drum rollers. With many years of experience in the manufacturing and processing of road rollers, we operate our own roller production facility, ensuring high-quality service and products while providing customers with comprehensive support.

Maintenance methods for the main clutch of a double‑drum vibratory roller. Rollers play an important role in our daily lives, and we take good care of them to ensure they keep working. Today, we hope this information will be helpful to everyone.

The vibratory roller shall be maintained every six months.

During maintenance, please replace the lubricating oil in the vibrating wheel; ensure thorough cleaning when changing the oil. The oil capacity of the vibration chamber is 14 liters. During testing, the oil supply line should be positioned at a 38° angle to the horizontal, with oil overflow from the drain hole serving as the reference point.

Main clutch maintenance

In addition to regularly adjusting the clutch’s operating mechanism, the main clutch should also be adjusted so that the front ends of its three release levers lie in the same plane and maintain a proper clearance—0.4 to 0.7 mm—from the release bearing’s jewel.

The connection and disengagement of the double‑drum roller should be smooth and gentle; avoid applying excessive force. When engaging the clutch, allow the clutch pedal to return to its original position until the clutch is fully engaged. To disengage the clutch, press the pedal all the way down until the clutch is completely disengaged. During operation, keep the clutch in a semi‑engaged state to prevent overheating and clutch failure. Regularly inspect the clutch to ensure that the friction plates and pressure plate surfaces remain free of oil or grease.
