Product Overview
3028422 Hydraulic Pump Gear (GEAR,HYDRAULIC PUMP) is a high-precision drive transmission gear specially matched for Cummins series diesel engine power steering hydraulic pumps. As the core power transmission part of the engine steering hydraulic system, it undertakes torque transmission and driving operation of the hydraulic pump, converting engine power into hydraulic pressure to ensure sensitive and labor-saving vehicle steering. This hydraulic pump gear effectively solves common steering system faults such as abnormal gear noise, jitter, insufficient steering power, hydraulic pump idle running and transmission failure caused by worn teeth, gear fatigue and poor meshing of old gears. It maintains stable hydraulic pump operation and smooth steering performance for long-term engine running.
Core Product Advantages
1. High-Hardness Alloy Steel Material: Adopts premium alloy steel with overall quenching and tempering heat treatment, featuring high surface hardness and strong impact resistance. It resists long-term high-load meshing wear and is not easy to tooth collapse or deformation.
2. Precision Gear Tooth Machining: Adopts CNC fine hobbing and grinding process with smooth tooth surface and accurate tooth profile. The meshing clearance is uniform, ensuring stable transmission, low running noise and no jitter or stuck phenomenon.
3. Excellent Fatigue Resistance: Optimized gear root transition design disperses meshing stress, effectively avoiding gear root fracture and fatigue damage under frequent start-stop and high-load operation, greatly extending service life.
4. High Temperature & Lubrication Adaptability: Stable mechanical performance in high-temperature engine working environment, compatible with high-pressure hydraulic oil lubrication. It maintains accurate meshing state without thermal deformation.
5. Anti-Corrosion & Oxidation Resistance: Surface anti-rust and passivation treatment prevents oxidation and corrosion, adapts complex engine working conditions, and keeps gear tooth precision for a long time.
6. Standard Specification Matching: Standard dimension 19cm*19cm*10cm and 2.107KG weight perfectly match Cummins engine hydraulic pump assembly, realizing accurate meshing and plug-and-play replacement without secondary modification.
7. Strict Factory Quality Testing: Finished gears pass gear precision detection, hardness test and meshing operation test, with stable batch quality for engine steering system maintenance and fleet bulk procurement.
