130104000256A019 Gear Ring Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 130104000256A019 gear ring is the core component of the outer ring of the planetary transmission in a speed reducer. It works in conjunction with the sun gear, planetary gears, and planet carrier to form a speed reduction transmission unit. By limiting the rotation trajectory of the planetary gears, it achieves speed reduction and torque increase, and stabilizes power output, directly affecting the transmission efficiency of the speed reducer and ensuring smooth operation of the equipment during travel and rotation.
This SANY original gear ring is forged from high-strength alloy, heat-treated and precision-machined internally, resulting in standard tooth profile, precise roundness, and a robust structure, suitable for harsh working conditions such as heavy-load start-stop and high-frequency vibration. Old gear rings are prone to wear, tooth breakage, and tooth deformation, leading to abnormal transmission noise, power slippage, torque loss, and in severe cases, causing the reducer to seize and stop. This product can be replaced in situ without damage, suitable for equipment maintenance, overhaul, and bulk stocking, effectively restoring transmission performance and reducing operation and maintenance costs and downtime.
