Helical / Spur Gear Shaft for Mud Pump & Heavy Duty Gearbox
Product Overview
The helical/spur gear shaft is a core high-torque transmission component designed for the power end of oilfield drilling mud pumps and large industrial gearboxes. It meshes with the gear ring to transmit power, converting high-speed rotation from the motor into low-speed, high-torque power to drive the reciprocating motion of the mud pump piston, ensuring stable and efficient mud circulation during drilling operations. This gear shaft is widely compatible with 3NB, F, UNB and other mainstream mud pump models, as well as heavy-duty industrial gearboxes for mining, metallurgy and other industries.
Key Features & Advantages
- Premium Material & Forging ProcessThe gear shaft is forged from high-strength alloy steel (42CrMo, 20CrMnTi, 40CrNiMo) with integral forging technology, delivering exceptional tensile strength, impact resistance, and fatigue resistance. It can withstand extreme high-load, high-impact working conditions in long-term continuous operation, effectively extending the service life of the entire transmission system.
- Precision Machining & Heat TreatmentAdopting CNC gear hobbing, grinding, and shaving processes, with strict control of tooth profile accuracy, pitch error, and surface finish. The gear teeth are carburized and quenched to achieve a surface hardness of HRC 58-62, with a core hardness of HRC 30-40, ensuring perfect wear resistance and impact resistance.
- Optimized Tooth Design
- Helical Gear Version: Smooth meshing, low noise, high load-bearing capacity, suitable for high-speed and heavy-load transmission.
- Spur Gear Version: Simple structure, easy manufacturing and maintenance, suitable for medium and low-speed heavy-load transmission.
- Strict Quality Inspection100% non-destructive testing (ultrasonic, magnetic particle) for material defects, gear accuracy testing, dynamic balance testing, and load testing before delivery, ensuring 100% product reliability and compliance with API 7K, ISO, AGMA international industry standards.
- Customized SolutionsWe provide fully customized gear shafts according to customer drawings, parameters, and application scenarios, supporting different modulus, number of teeth, shaft diameter, and material requirements, to meet the special needs of various mud pump models and heavy equipment.
