Custom Large Crown Wheel & Pinion Sets | Straight Bevel Gears

Precision-Engineered for High-Torque, Right-Angle Drivetrains

In any differential or right-angle gearbox, the crown wheel and pinion set is the heart of the system. These gears must transmit immense torque, withstand shock loads, and operate smoothly and quietly for thousands of hours. The precision of their design and manufacturing is the difference between a reliable drivetrain and a catastrophic failure.

Yile Machinery is an OEM manufacturer specializing in heavy-duty, custom-forged crown wheel and pinion sets. We produce precision-matched straight bevel gears engineered for maximum strength and durability in the most demanding industrial and automotive applications.

Key Features & Benefits:

• Superior Strength Through Forging: Our gears begin as high-quality forged steel blanks, not simple bar stock. This process aligns the steel's grain structure to the gear's shape, creating a component with exceptional resistance to shock loads and tooth-bending fatigue.

• High-Performance Gear Steels: We utilize specialized carburizing steels like 20CrMnTi, which are designed for gear applications. These alloys provide an ideal base for creating a gear with a super-hard surface and a tough, ductile core.

• Optimized for Durability with Heat Treatment: Every gear set undergoes a precise carburizing and quenching heat treatment process. This creates an extremely hard (HRC 58-62), wear-resistant tooth surface while maintaining the core's toughness to absorb impacts without fracturing.

• Precision Gear Cutting for Smooth Operation: Using advanced gear hobbing and milling processes, we cut the gear teeth to exacting standards. This ensures a perfect mesh between the crown wheel and pinion, resulting in efficient power transfer, low noise, and extended service life.

• Supplied as Lapped & Matched Sets: A crown wheel and pinion are not individual parts; they are a single system. We machine, heat-treat, and finish them as a matched pair, lapping them together to guarantee a perfect contact pattern and optimal performance right out of the box.

• Complete OEM Manufacturing: From your technical drawings, we manage the entire production cycle—forging, machining, heat treatment, and final inspection—to deliver a finished gear set that meets your exact specifications.
