In infrastructure construction, such as highways, municipal projects, and airport runways, rollers are critical equipment for pavement compaction. Their performance directly impacts the strength, stability, and service life of the road. The ability of rollers to consistently and stably deliver compaction performance depends on high-quality spare parts. From the core components that transmit power to the working mechanism parts that ensure precise compaction, each part plays a crucial role in the operation of the roller. This series will systematically review relevant information about roller spare parts, providing comprehensive guidance from identifying types to purchasing tips and maintenance methods. In the previous article, we analyzed the importance of roller spare parts. In this article, we will explore common types of roller spare parts.
Powertrain Spare Parts
The powertrain is the “power transmission link” of a roller, and its spare parts directly affect the equipment’s power output and operating efficiency. These include engine spare parts (such as pistons, connecting rods, fuel injectors, and air filters), clutches, transmission spare parts (such as gears, bearings, and synchronizers), drive shafts, and drive axles. The engine is the power source, and its fuel injectors, fuel filters, and other components ensure complete fuel combustion, improving engine efficiency. The gears and bearings within the transmission are precision-driven and robust, ensuring smooth power transmission and minimizing energy loss. For fully hydraulic rollers, the hydraulic transmission system’s hydraulic pump, hydraulic motor, and other components are core components, their performance determining the roller’s travel speed and operating power.
Vibration System Parts
The vibration system is the core operating system of a vibratory roller, and the performance of its components directly determines compaction performance. It primarily includes the vibratory motor, vibratory shaft, eccentric weight, vibratory bearing, and shock absorber. The vibrating motor provides power for the vibration system. Its output torque and speed stability affect the vibration frequency. The quality and installation accuracy of the eccentric weight determine the vibration amplitude, which is directly related to the compaction depth and intensity. The vibrating bearing must withstand high-frequency vibration and heavy loads and must possess excellent wear resistance and fatigue resistance. The shock absorber reduces the transmission of vibration to the frame and cab, protecting other equipment components and the operator.
Working Attachment Spare Parts
Working attachment spare parts vary depending on the roller type and are key components that directly enable compaction. Working attachment spare parts for static rollers primarily include steel drums, axles, and rims. The steel drum surface undergoes special treatment for excellent wear resistance and smoothness, ensuring smooth compaction. Working attachment spare parts for tire rollers primarily involve compacting tires. Tire pressure, tread pattern, and wear resistance are selected based on the working material and road surface requirements. Furthermore, working attachment lifting system spare parts, such as hydraulic cylinders and hydraulic locks, enable flexible raising and lowering of the drum or tire to meet the needs of various operating scenarios.
Brake and Steering System Spare Parts
Brake and steering system spare parts are core components that ensure safe operation of road rollers. Brake system spare parts include the brake pedal, brake pump, brake pads, and brake hoses. The wear resistance of the brake pads and the pressure stability of the brake pump directly affect braking performance. Steering system spare parts mainly include the steering cylinder, steering tie rod, steering knuckle, and steering pump. The steering cylinder enables precise steering angle control, while the steering tie rod and steering knuckle must possess sufficient strength and rigidity to ensure reliable steering. For large road rollers, spare parts such as the hydraulic pump and control valve of the power steering system can reduce operating effort and improve steering flexibility.
Hydraulic and Electrical System Spare Parts
Hydraulic system spare parts are widely used in road rollers and include hydraulic pumps, hydraulic cylinders, hydraulic valves (such as relief valves and reversing valves), hydraulic hoses, and hydraulic oil filters. The hydraulic pump supplies pressurized oil to the entire hydraulic system. Hydraulic valves control the direction, pressure, and flow of the hydraulic oil, ensuring the coordinated operation of all hydraulic actuators. Hydraulic oil filters filter impurities from the oil, protecting precision components such as the hydraulic pump and motor. Electrical system spare parts include batteries, generators, starter motors, sensors, and instrument panels. Sensors monitor parameters such as engine speed, oil temperature, and oil pressure in real time, while the instrument panel provides a visual display of this information, allowing operators to easily understand the equipment’s operating status.
