Input secondary gear

Product Introduction

The secondary input gear is a core intermediate transmission component of the loader’s gearbox. It connects the primary input gear to the subsequent transmission components, receiving power from the primary gear and performing secondary reduction and torque conversion. This ensures smooth power delivery to the output end, guaranteeing seamless power transitions for the machine’s operation.

Forged from 20CrMnTi alloy carburized steel, it undergoes precision processes such as carburizing and quenching, precision grinding, and aging treatment. This results in high tooth surface hardness and sufficient tooth root toughness, making it resistant to tooth breakage, wear, and failure. The precise tooth profile and uniform meshing clearance ensure smooth transmission, low noise, impact resistance, high speed resistance, and resistance to high-temperature oil corrosion. Overall precision meets original factory standards, ensuring strong interchangeability. It can directly replace original vehicle parts without modification and is compatible with the assembly and repair of various loader gearboxes.

Application Scenarios

• Construction Sites: Earthwork excavation, backfilling, road construction; frequent gear shifting, low-speed heavy-load operation; stable gear meshing without slippage or skipping.
• Mining and Quarrying: Heavy-load climbing, bumpy road conditions; withstands continuous high-torque impact; pressure-resistant, wear-resistant, fatigue-resistant; not easily damaged during long-term operation.
• Sand and Gravel Yards, Coal Yards, and Mixing Plants: Continuous high-frequency loading and transportation around the clock; slow temperature rise and minimal attenuation under high load; low failure rate.
• Complete Machine Matching and Maintenance: Compatible with 3-ton, 5-ton, 6-ton, and 7-ton wheel loader gearbox repair and replacement; new machine installation; compatible with mainstream models.
• Harsh Working Conditions: Adaptable to dusty, high-oil-temperature, and high-frequency vibration conditions; corrosion-resistant and not easily deformed; suitable for complex construction site operation scenarios.
