Custom Geared Drums for Hoists & Winches

Integrated Gear and Drum Manufacturing for Maximum Torque and Reliability

In high-torque hoisting and pulling applications, a standard bolt-on ring gear can be a point of failure. For ultimate strength and performance, the gear teeth must be an integral part of the drum itself.

Yile Machinery is a specialist manufacturer of custom helical geared drums. We machine high-precision gear teeth directly into the surface of heavy-duty winch and hoist drums, creating a single, monolithic component engineered for maximum power transmission and exceptional service life in the most demanding environments.

Key Features & Benefits:

• Integrated Design for Ultimate Strength: By cutting the gear teeth directly into the drum body, we eliminate the need for bolts or welds, creating a seamless component with no weak points. This design ensures maximum torque transfer and resistance to shear stress.

• Precision Helical Gear Cutting: We utilize advanced 5-axis CNC machining centers and gear hobbing technology to produce precise helical gear profiles. This ensures smooth, quiet, and efficient engagement with the drive pinion, even under extreme loads.

• High-Strength Materials: Our geared drums are manufactured from high-quality forged or rolled steel alloys (e.g., 42CrMo, 34CrNiMo6) chosen for their excellent tensile strength, toughness, and fatigue resistance.

• Optimized Tooth Hardening: The gear teeth undergo a specialized induction hardening process to achieve superior surface hardness and wear resistance, while the drum core remains tough and ductile to absorb shock loads.

• Large Diameter & Custom Fabrication: We have the capability to manufacture large-diameter geared drums, complete with integrated flanges, cable grooves, and bearing journals, all machined to your exact engineering specifications.
