High-Performance Gear Reducers for Heavy Machinery

Equipped with advanced production facilities and manufacturing processes, Fedia possesses comprehensive testing capabilities and strong technical expertise. Our gear reducers are widely recognized and trusted by customers and exported to over 20 countries. We welcome your consultation and look forward to establishing a long-term and stable cooperative relationship with you.

Feida gear reducers are precision mechanical transmission devices usually installed between a power source (e.g., an electric motor, an internal combustion engine, or a hydraulic motor) and a working machine, converting high-speed, low-torque input into low-speed, high-torque output. They transmit power through the meshing of gears with different numbers of teeth. When a small gear drives a larger gear, the output speed decreases, while the output torgue increases.

Main Components

Housing: Supports and protects the internal gears, shafts, and bearings; contains the lubricating oil and helps dissipate heat. Common materials include cast iron, cast steel, and aluminum alloys.
Gears: Serve as the core transmission components of a reducer; transmit power and achieve speed reduction. Depending on the design and application, gear types may include spur gears, helical gears, herringbone gears, bevel gears, and worm gears.
Shafts: Support the gears and transmit torque. Common types include input shafts, intermediate shafts, and output shafts. The strength, stiffness, and alignment accuracy of the shafts directly affect the reducer's operating performance.
Bearings: Support rotating shafts, reduce friction, and withstand radial or axial loads.
Seals: Prevent lubricant leakage and keep dust, water, and other contaminants from entering the housing.
Lubrication Oil: Reduces friction and wear between gears and bearings while helping dissipate heat.
Common Accessories: Include breathers, oil-level indicators, drain plugs, sight glasses, and temperature monitoring devices.

Main Types

Our gear reducers can be classified into several types according to their gear structures, transmission methods, and applications. These types include spur, helical, bevel, worm, and planetary gear reducers.
