II. Core Advantages: Six Core Strengths, Shaping Transmission Excellence
1. High-Precision Transmission, Stable Operation
Adopting high-precision grinding helical gears with advanced tooth profile correction technology, the series achieves meshing accuracy up to GB/T 10095.2 Class 5 standard. The parallel axis layout with optimized center distance ensures uniform force distribution during gear meshing, reducing transmission backlash to ≤3arcmin (customizable to ≤1arcmin for precision models). The transmission efficiency reaches 95%-98% for two-stage transmission and 93%-96% for three-stage transmission, minimizing power loss. The smooth meshing characteristics of helical gears keep operating noise ≤70dB at 1m distance, creating a quiet and efficient production environment.
2. Model-Specific Optimization, Strong Adaptability
Each model in the series is optimized for targeted scenarios: FAZ..R and FAF..R models are designed for high-speed precision transmission, ideal for automated production lines; FA..R models excel in medium-load continuous operation, suitable for general manufacturing equipment; F..R models feature enhanced load-bearing capacity, adapting to heavy-duty processing scenarios; FHZ and FHF models are equipped with special sealing structures, optimized for dusty and humid working environments. This targeted design ensures that each model can exert optimal performance in its respective application scenario.
3. Robust Load-Bearing Capacity, Long Service Life
Gears and shafts are made of high-strength 20CrMnTi alloy steel, processed through integral carburizing, quenching and precision grinding, with surface hardness up to HRC 60-64 and core hardness HRC 30-35, ensuring excellent wear resistance and impact toughness. The optimized gear tooth width design increases the effective meshing area by 35% compared to standard models, with rated output torque ranging from 80N·m to 12000N·m. The one-piece cast iron housing with rib reinforcement design enhances structural rigidity, effectively dispersing transmission stress and preventing deformation, ensuring a service life of over 12 years under normal maintenance.
4. Flexible Installation, Easy Configuration
The series supports multiple installation modes including base-mounted, flange-mounted (B5/B14), and torque arm-mounted, compatible with various motor connection methods. The output shaft offers diverse configurations such as solid shaft with flat key, spline solid shaft, hollow shaft with locking disk, and hollow shaft with involute spline. It can be flexibly matched with motors of 0.25kW-110kW power and reduction ratios of 2.5-360 (two-stage/three-stage combination), meeting the personalized configuration needs of different equipment.
5. Advanced Sealing System, Wide Environmental Adaptability
Equipped with a composite sealing structure of double-lip oil seal + labyrinth seal + O-ring, the reducer achieves IP55 protection level (IP65 available for customization). This structure effectively blocks the intrusion of dust, moisture and corrosive media, ensuring stable operation in harsh environments such as high temperature, high humidity and dusty workshops. The rational internal oil circuit design and forced lubrication option (for high-speed models) ensure sufficient lubrication of all transmission components, enabling normal operation in the temperature range of -30℃ to +90℃.
6. Convenient Maintenance, Cost-Saving Operation
The modular design enables quick disassembly and assembly of components, with high interchangeability of spare parts, greatly reducing maintenance time and labor costs. Centralized oil filling and drainage ports and oil level observation windows facilitate daily lubrication management; it is recommended to use 220#/320# industrial gear oil, with oil change intervals of 500 hours for the first use and 6000 hours for subsequent regular maintenance. The high reliability and long service life of the product significantly lower the total cost of ownership for customers.

V. Installation and Maintenance: Scientific Operation, Maximizing Performance
During installation, ensure the coaxiality error between the reducer and the motor is ≤0.1mm and the parallelism error ≤0.08mm to avoid abnormal wear of gears. Select lubricating oil according to the working temperature: use 220# industrial gear oil for normal temperature (0℃-40℃) and 320# for high temperature (40℃-90℃). Check the oil level regularly to ensure it is within the standard range; replace the oil after the first 500 hours of operation, and perform comprehensive maintenance every 6000 hours, including checking gear meshing status, sealing performance and tightening fasteners. If abnormal phenomena such as excessive noise, overheating or oil leakage occur, stop the machine immediately for inspection and troubleshooting.
