Product Introduction: Oil Pump Gear Oil pump gear is the core transmission component of the forced lubrication system on triplex mud pumps, widely applied in oilfield drilling, geological prospecting and horizontal directional trenchless engineering. Paired with pump housing, bearings and gear shafts, it rotates to deliver lubricating oil to crankshaft, crossheads, piston rods and other power-end moving parts. Manufactured from high-hardness alloy steel via precision forging, gear hobbing and overall quenching & tempering, this gear features high surface hardness, strong wear resistance and outstanding fatigue resistance. Accurate tooth profile machining ensures smooth meshing with mating gears, low running noise and stable oil supply flow without oil supply interruption under long-term heavy-load operation. Optimized tooth clearance design reduces friction heat during high-speed rotation and avoids abnormal tooth surface abrasion, pitting or tooth breaking. Strict dimensional tolerance control guarantees perfect assembly clearance with gear shafts and oil pump shells, preventing oil leakage and insufficient lubrication pressure. Surface anti-corrosion treatment adapts to complex working environments mixed with lubricating oil, mud and chemical additives. Standard specifications provide excellent interchangeability, compatible with most mainstream mud pump lubrication assemblies. Compact structure supports quick disassembly and replacement during routine maintenance, cutting equipment downtime. It ensures full and uniform lubrication of all transmission components, effectively lowering mechanical wear and heat accumulation, extending the service life of power-end core parts. It is an indispensable key component to maintain stable and safe operation of mud pump power assembly.
