The shaft and gear set is the foundational mechanical heart of an external hydraulic gear pump. Consisting of a precision-matched drive gear (integrating the input shaft) and a driven gear (idler gear), this assembly executes critical system processes:
- Hydraulic Flow Generation: As the drive shaft rotates the meshing gears, fluid is drawn from the inlet port, trapped between the gear teeth and the housing walls, and forcibly discharged into the high-pressure system lines.
- Matched-Set Precision: RCHC shafts and gears are manufactured and supplied strictly as matched pairs. This ensures perfect involute tooth profiles mesh flawlessly, reducing internal fluid pulsation, minimizing operating noise, and preventing localized friction wear.
- High Torque Transmission: Engineered to withstand rapid pressure spikes and continuous rotational fatigue under full system load configurations (exceeding 3,000 PSI / 207 bar).
2. Premium Material & Metallurgical Engineering
RCHC enforces strict material controls and surface finishing protocols to counter mechanical bending and gear tooth pitting:
- Base Core Material: Forged from premium high-strength Alloy Steel (AISI 8620 / 20CrNiMo), renowned for its superior core toughness and resistance to high torsional shocks.
- Advanced Case Hardening: All gears undergo precision gas carburizing and heat treatment, achieving a deep case hardness of HRC 58-62. This process yields an incredibly hard, wear-resistant outer shell while maintaining a ductile inner core to resist fracture under shock loads.
- Precision Tooth Grinding: Gear teeth profiles are finished on state-of-the-art CNC grinding machines. This provides a clean profile finish that minimizes backlash, dramatically optimizes volumetric output, and prevents early thrust plate scoring.
