Product Description
The pinion shaft is the workhorse of any gearbox or drive system. As the input gear, it endures high rotational speeds and is the first point of contact for transmitting immense torque. For heavy industrial applications, a helical pinion shaft offers the ultimate combination of strength, smooth power transmission, and quiet operation.
Yile Machinery specializes in manufacturing custom, large-module helical pinion shafts from your technical drawings, engineered for maximum performance and service life in the most demanding environments.
Unlike spur gears with straight teeth, helical gears have teeth that are cut at an angle. This design provides significant advantages in high-load applications:
Higher Load Capacity: The angled teeth engage gradually, distributing the load across multiple teeth at once. This increases the total torque capacity and reduces stress on individual teeth.
Smoother & Quieter Operation: The gradual engagement and disengagement of the teeth result in a smoother, quieter operation with less vibration compared to spur gears.
Increased Strength: The angled tooth profile provides greater bending strength, making helical pinions ideal for handling heavy and shock loads.
A high-performance pinion shaft is the product of a precise and controlled manufacturing process. We ensure quality at every stage.
We begin with a solid billet of high-strength forged alloy steel, such as 42CrMo (AISI 4140) , 34CrNiMo6 (AISI 4340) , or 18CrNiMo7-6. The forging process creates a superior, continuous grain structure that provides exceptional resistance to fatigue and impact—critical for a long-lasting pinion.
To withstand intense contact stress and wear, the pinion must be hardened. We utilize specialized heat treatment processes:
Carburizing & Quenching: Creates an extremely hard (HRC 58-62) outer case on the gear teeth for maximum wear resistance.
Quenching & Tempering: Develops a strong, tough core that can absorb shock loads without fracturing.
After heat treatment, the shaft is finished with high-precision processes:
CNC Machining: The shaft body and bearing journals are machined to exact tolerances.
Precision Gear Grinding: The hardened gear teeth are ground on a CNC gear grinding machine. This critical final step corrects any minor distortions from heat treatment and produces a highly accurate tooth profile and a super-fine surface finish, ensuring a perfect mesh and extended operational life.
We are equipped to handle your most demanding custom pinion shaft requirements:
Large Module Gears: We have extensive experience with large module pinions for heavy-duty applications.
Long Shafts: Our facilities can accommodate the manufacturing of long and complex pinion shafts.
Full Customization: We manufacture directly from your engineering drawings and specifications to create a perfect replacement or new component for your machinery.
