Product Description
Yile Machinery is a premier manufacturer of custom forged steel spur gears for demanding industrial power transmission applications. By starting with a forged blank, we produce gears with superior strength, impact resistance, and fatigue life compared to components machined from standard bar stock or castings. We deliver a finished, precision-machined gear ready for integration into your industrial gearboxes, pumps, and heavy machinery.
A gear is only as strong as the material it's made from. The forging process creates a component that is fundamentally tougher and more reliable.
Superior Strength & Toughness: Forging aligns the grain flow of the steel to the shape of the gear, eliminating the weak points found in standard bar stock. This results in exceptional resistance to shock loads and tooth breakage.
Increased Fatigue Life: The refined grain structure created by forging significantly increases the gear's ability to withstand cyclic loading, leading to a longer operational lifespan.
Guaranteed Material Integrity: The forging process helps to reveal and eliminate internal material defects like porosity or inclusions, ensuring a solid and reliable component.
Material Selection: We begin with certified carbon and alloy steels, including C45 (AISI 1045) for general applications and higher-strength alloys like 42CrMo (AISI 4140) for more demanding loads.
Die Forging: The raw material is heated and forged in a die to create a "near-net shape" blank. This critical step establishes the optimized grain flow that provides superior strength.
CNC Machining: The forged blank is precision-machined on CNC lathes and mills to create the bore, hub, faces, and any required features like keyways or lightening holes.
Precision Gear Cutting: Using state-of-the-art CNC Gear Hobbing or Gear Shaping machines, we cut the spur gear teeth to precise AGMA or DIN quality standards, ensuring smooth, quiet, and efficient operation.
Selective Heat Treatment: To maximize wear resistance, the gear teeth can be selectively hardened via induction hardening or flame hardening. This process creates a very hard outer surface (typically 50-58 HRC) to resist wear, while the core of the gear remains ductile and tough to absorb impacts.
We manufacture spur gears tailored to your exact requirements. Customization options include:
Dimensions: Outside Diameter, Face Width, and Hub Configuration
Gear Parameters: Module, Diametral Pitch, Pressure Angle, and Tooth Count
Material: C45, 40Cr, 42CrMo, and other alloys upon request
Bore: Plain, Keyed, Splined, or Tapered Bores
Heat Treatment: Specific hardness and case depth requirements
