Product Description
Yile Machinery specializes in the manufacture of high-performance spiral bevel gears designed to transmit power through a right-angle (90°) drive. Engineered for superior strength and smooth, quiet operation, our custom bevel gears are the ideal solution for the most demanding industrial gearboxes and powertrain systems.
Unlike straight bevel gears, the curved teeth of a spiral bevel gear engage gradually. This continuous contact ensures a smoother, quieter, and more efficient transfer of power.
Higher Torque Capacity: The spiral design allows for greater tooth surface contact, enabling the transmission of higher loads and torque.
Reduced Vibration and Noise: The gradual engagement minimizes impact, resulting in significantly lower noise and vibration, even at high speeds.
High-Strength Design: Ideal for applications involving high shock loads and heavy-duty use.
The performance of a gear is defined by its material. We manufacture our premium bevel gears from high-grade forged alloy steels to ensure maximum reliability.
Featured Material: 30CrNiMo8 (1.6580)
This high-tensile nickel-chromium-molybdenum alloy steel is chosen for its exceptional properties:
Extreme Toughness and Strength: Provides outstanding resistance to shock loads and fatigue.
Excellent Hardenability: Allows for deep and uniform hardening for superior wear resistance.
Performance Under Stress: Ideal for critical components subjected to high dynamic and torsional stresses.
We also manufacture gears from other high-quality alloys, including 42CrMo (AISI 4140) and customer-specified materials, always starting with forged blanks for a superior grain structure and strength.
A perfect bevel gear is not just a single part; it's half of a perfectly matched set. Our manufacturing process is optimized to create precision-lapped gear sets for optimal contact and performance.
Forging & Material Preparation: We begin with a quality-inspected forged blank, which is heat-treated to refine its metallurgical structure.
Precision CNC Machining: The blank is precision-turned and machined to establish all critical mounting surfaces and dimensions.
Advanced 5-Axis Gear Cutting: We utilize advanced 5-axis CNC gear cutting machines to generate the complex spiral tooth geometry with exceptional accuracy.
Controlled Heat Treatment: The gear undergoes a specialized heat treatment process (e.g., carburizing and hardening) to achieve a hard, wear-resistant surface while maintaining a tough, ductile core.
Precision Grinding & Lapping: After heat treatment, the gear teeth are precision ground to correct any minor distortions. Critically, the gear and its matching pinion are lapped together as a set, creating a perfect, mated contact pattern for their entire service life.
Final Quality Assurance: Each gear set is tested for its contact pattern (using marking compound) and subjected to rigorous dimensional and material inspection.
