Core functions and roles
This small gear is usually installed inside the walking gearbox or vibration wheel reduction mechanism of the roller, and is a key meshing component in the power transmission chain:
Power transmission: responsible for transmitting the rotational power output by the hydraulic motor or engine to the large gear or subsequent transmission shaft.
Variable speed torque increase: By using a specific gear ratio for one or more stages of reduction, the output torque is significantly increased, providing strong walking traction or high-frequency vibration force for the road roller.
Material and Manufacturing Process
As the core gear that can withstand heavy loads, high speeds, and frequent impacts, it has extremely high mechanical performance:
High quality alloy steel: usually made of 20CrMnTi or similar high-strength alloy carburizing steel, with a tough core that is not easily broken.
Precision machining: The tooth surface undergoes high-precision grinding to ensure smooth meshing and low noise; And after deep carburizing and quenching treatment, the surface hardness is extremely high, with excellent resistance to pitting corrosion and wear.
Application scenarios and working conditions
XCMG XDH080J is a 0.8-ton miniature double steel wheel roller. With its small size and strong maneuverability, this small gear is mainly used in the following high-frequency operation scenarios:
Municipal road maintenance and upkeep
In asphalt pavement repair, compaction around manhole covers, and other projects, the roller needs to frequently perform forward and backward reversing operations, and the small gear tooth surface needs to withstand the severe impact of alternating loads.
Backfilling and compaction of trenches
In the narrow trench backfilling operation after pipeline laying, equipment often operates in a semi clutch or high load state, requiring small gears to have strong anti overload and anti adhesive capabilities.
Site leveling and foundation compaction
In the compaction operation of the foundation cushion layer in the basement roof, parking lot or square of the community, the equipment is in a continuous vibration state for a long time, and the small gear needs to maintain stable power output under high-speed operation.
