275002361 main reducer assembly for XCMG XP225H single drum roller

Short Description:

275002361 Main reducer assembly is the core middle transmission component of XCMG XS225H single-drum roller. Different from the wheel-side reducer that undertakes terminal power output, this main reducer is responsible for primary deceleration and torque conversion of the whole drive system. It matches the transmission output power, distributes power to the left and right wheel-side reduction mechanisms stably, and is the key power transfer hub to ensure the coordinated operation of the roller’s walking and compaction system.

description

Part Number: 275002361
Applicable Model: XCMG XS225H Single-Drum Roller
Product Name: Main Reducer Assembly
Core Structure: Primary spiral bevel gear reduction + integrated differential unit
Main Material: Ultra-high strength carburized alloy steel + cast alloy housing
Core Function: Primary speed reduction, torque amplification, equal power distribution
Lubrication Mode: Forced circulation + splash composite lubrication
Sealing Form: Multi-channel combined sealing structure
Matching Parts: Drive axle housing, half shaft assembly, wheel-side reducer

Specially suitable for XCMG XS225H single-drum roller. It is fixedly installed in the middle section of the drive axle, adapting to medium and high torque continuous output, frequent start-stop switching of construction working conditions, long-term alternating vibration, and complex and harsh working environments such as gravel road surfaces and muddy foundation compaction operations.

advantages

Professional primary reduction ratio design, which can efficiently convert engine power, reduce the operating load of the wheel-side secondary reduction system, and extend the overall service life of the drive system.
Precision paired spiral bevel gear set, with uniform meshing stress, low transmission noise and high power conversion efficiency, avoiding power loss during compaction operation.
Integrated differential structure with optimized stress design, which can adapt to the speed difference of left and right wheels during steering and walking, ensuring flexible steering and stable straight-line driving.
Adopts composite lubrication and multi-layer sealing technology, which solves the problems of poor lubrication and oil leakage of the middle transmission part under long-term vibration working conditions.
Integral cast high-rigidity housing, strong compression and impact resistance, not easy to deform under overall load, and high operation stability.

maintenance & replacement tips

Regularly check the lubricating oil level and oil quality of the main reducer, replace the special gear oil regularly, and avoid dry grinding and insufficient lubrication.
Pay attention to abnormal noise and jitter during equipment operation to judge the meshing state of the internal gear set in time.
Check the sealing parts regularly to eliminate oil leakage and prevent dust and muddy water from entering the cavity to wear parts.
Avoid long-term overload operation and sharp turning with heavy load, so as to prevent excessive gear stress and tooth surface damage.
Use original 275002361 main reducer assembly to ensure the matching accuracy of the middle transmission system and stable power output of the whole machine.
