2186796 Auger Shaft for S1900 S2100-3

Product Overview

The auger shaft of a paver is the core transmission component of the material distribution system. Installed inside the hopper, it evenly conveys asphalt mixture to the front of the screed through the rotation of spiral blades, ensuring consistent material distribution across the paving width. Made of high-strength alloy material, it has excellent wear and impact resistance, adapting to the continuous friction of mixture and harsh working conditions at construction sites. Linked with the drive motor and reducer, the auger shaft can flexibly adjust its speed according to paving speed, avoiding material accumulation or interruption. With a compact structural design and good sealing performance, it can effectively prevent mixture particles from entering bearings and causing jamming. Routine maintenance only requires regular cleaning of blades and inspection of bearing conditions, making it a key device to ensure continuous and stable paving operations and improve pavement forming quality.

Working Principle

The operation of the paver auger shaft centers on uniform material distribution and adapting to paving rhythm. During operation, the auger shaft starts with the conveying of asphalt mixture in the hopper. The drive motor transmits power through the reducer to drive the spiral blades on the shaft to rotate synchronously. By virtue of spiral thrust, the blades push the mixture in the hopper to both sides or the middle in a directional manner, quickly filling the material distribution space in front of the screed and ensuring consistent material thickness across the paving width. The speed of the auger shaft can be flexibly adjusted according to the paver's travel speed: higher speed when the paver moves fast to avoid material interruption, and lower speed when it moves slow to prevent material accumulation. Its good sealing structure can block mixture particles from entering the bearings, ensuring stable rotation of the shaft and providing a uniform and continuous material foundation for the subsequent compaction and forming of the screed.
