II. Core Advantages: Five Core Strengths, Leading Transmission Standards
1. High Transmission Efficiency, Energy-Saving Operation
Adopting precision-ground helical gears with optimized tooth profile modification technology, the F-Series achieves meshing accuracy up to GB/T 10095.2 Class 5 standard. The parallel axis transmission structure minimizes power loss during operation, with a transmission efficiency of 94%-98% for two-stage transmission and 92%-96% for three-stage transmission, significantly reducing energy consumption compared to conventional parallel axis reducers. The smooth meshing of helical gears effectively lowers operation noise, with a noise level ≤72dB at 1m distance, creating a more comfortable and environmentally friendly workshop environment.
2. Strong Load-Bearing Capacity, Stable Operation
Key components such as gears and shafts are made of high-strength alloy steel, processed through integral carburizing, quenching and tempering treatment, with a surface hardness reaching HRC 60-64, ensuring excellent wear resistance and fatigue strength. The optimized gear contact design increases the effective meshing area by 40% compared to standard structures, with a rated output torque ranging from 120N·m to 18000N·m. The integrated cast iron housing features high rigidity and good shock absorption, which can evenly disperse the transmission stress and avoid deformation, ensuring long-term stable operation even under heavy-load and continuous working conditions.
3. Diversified Models, Flexible Adaptation
The F-Series offers a complete range of models to meet diverse application needs: FHZ..R and FHF..R models are suitable for high-precision transmission scenarios; FH..R and FH..BR models excel in heavy-load operation environments; FA..BR and FF..R models are optimized for special installation requirements. It supports multiple installation methods including base-mounted, flange-mounted, small flange-mounted and torque arm-mounted, and the output shaft can be configured as solid shaft (flat key/spline) or hollow shaft (locking disk/involute spline). The series is compatible with motor power ranging from 0.37kW to 160kW and reduction ratio of 2.8-400 (two-stage/three-stage combination), enabling flexible matching according to different equipment requirements.
4. Reliable Sealing, Wide Environmental Adaptability
Equipped with a multi-layer sealing system consisting of high-quality oil seals and labyrinth seals, the reducer achieves an IP55 protection level (IP65 customizable), which can effectively prevent the intrusion of dust, moisture and oil leakage, ensuring stable operation in harsh industrial environments such as dusty mines and humid ports. The rational internal oil circuit design ensures sufficient lubrication of all transmission components, and the product can work normally in an operating temperature range of -25℃ to +90℃, with strong environmental adaptability.
5. Easy Maintenance, Cost-Effective Operation
Benefiting from the modular design, the components of the F-Series are highly interchangeable, facilitating quick disassembly, inspection and replacement during maintenance. The centralized oil filling and drainage ports simplify the lubricating oil replacement process, reducing maintenance time and labor costs. With standardized production and strict quality control, the product has a service life of more than 12 years under normal maintenance, greatly reducing the total operation cost of customers.

V. Installation and Maintenance: Scientific Operation, Maximizing Service Life
During installation, ensure that the parallelism error between the reducer and the motor shaft is ≤0.08mm to avoid abnormal wear of gears caused by misalignment. It is recommended to use 320# heavy-duty industrial gear oil for lubrication; check the oil level regularly to ensure sufficient lubrication of transmission components. Replace the lubricating oil after the first 800 hours of operation, and perform regular maintenance every 6000 hours thereafter, including gear meshing inspection, seal integrity check and fastener tightening. If abnormal heating or vibration occurs during operation, stop the machine immediately for inspection to prevent further damage to the equipment.
