I. Product Overview: Customized Modular Design, Leading Transmission Performance
Weigao’s F-Series Parallel Axis Helical Gear Reducer, covering key models including FH, FH..B, FA..B, FF, FAZ, and FAF, is a high-performance power transmission device specifically developed for medium to heavy-duty parallel axis drive scenarios. Based on a reinforced modular design platform, this series integrates high-strength helical gear transmission technology and optimized load-bearing structural layout, achieving an excellent balance of high torque output, stable operation and compact volume. It effectively solves the pain points of traditional parallel axis reducers such as insufficient load capacity under heavy-duty conditions and poor structural stability, and can maintain reliable power transmission in complex working environments involving frequent start-stop, impact load and long-term continuous operation. With its model-specific structural advantages and broad compatibility, it has become a core transmission component in industries such as construction machinery supporting, mining equipment, bulk material handling, and heavy-duty manufacturing, providing strong power support for the high-efficiency and stable upgrading of industrial production. As a key export product of Weigao, this series has been exported to more than 80 countries and regions around the world, winning wide trust from global customers with its robust performance.
II. Core Advantages: Six Core Strengths, Shaping Transmission Excellence
1. High-Precision Transmission, Stable Operation
Adopting high-precision grinding helical gears with optimized tooth profile and lead correction technology, the series achieves meshing accuracy up to GB/T 10095.2 Class 5 standard. The parallel axis transmission structure with reinforced bearing support ensures uniform force distribution during gear meshing, reducing transmission backlash to ≤4arcmin (precision models can be customized to ≤2arcmin). The transmission efficiency reaches 94%-97% for two-stage transmission and 92%-95% for three-stage transmission, effectively reducing energy loss during power transmission. The smooth meshing of helical gears and optimized housing structure design minimize operating noise, with the noise level ≤73dB at 1m distance, creating a stable and quiet working environment.
2. Model-Specific Optimization, Strong Adaptability
Each model in the series is tailored for specific working conditions: FH models are designed for heavy-duty continuous operation, suitable for large-scale conveying equipment; FH..B models feature a reinforced housing structure, adapting to high-impact load scenarios such as mining machinery; FA..B models adopt a compact flange-mounted design, ideal for equipment with limited installation space; FF models are optimized for multi-angle installation, suitable for complex layout requirements; FAZ and FAF models focus on high-speed precision transmission, matching the needs of automated heavy-duty processing lines. This targeted model design ensures that the product can exert optimal performance in different industrial scenarios.
3. Robust Load-Bearing Capacity, Long Service Life
Gears and transmission shafts are made of high-strength 20CrNiMo alloy steel, processed through integral carburizing, quenching, tempering and precision grinding processes. The surface hardness reaches HRC 61-65, and the core hardness is HRC 32-38, which gives the components excellent wear resistance, fatigue resistance and impact toughness. The optimized gear tooth width and modulus design increase the effective meshing area by 40% compared to standard models, with the rated output torque ranging from 150N·m to 15000N·m. The one-piece cast iron housing with enhanced rib reinforcement design has strong structural rigidity and shock absorption capacity, which can effectively disperse transmission stress and prevent housing deformation, ensuring a service life of more than 12 years under normal maintenance and heavy-duty operation conditions.
4. Flexible Installation, Easy Configuration
The series supports a variety of installation modes to meet diverse layout needs, including base-mounted, flange-mounted (B5/B14), small flange-mounted and torque arm-mounted. The output shaft can be configured with multiple options 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 with power ranging from 0.37kW to 132kW and reduction ratios of 2.8-380 (two-stage/three-stage combination), realizing personalized configuration according to the power and speed requirements of different equipment.
5. Advanced Sealing System, Wide Environmental Adaptability
Equipped with a multi-layer composite sealing system composed of high-temperature resistant double-lip oil seal, labyrinth seal and O-ring, the reducer achieves IP55 protection level (IP65 can be customized according to needs). This sealing structure can effectively prevent the intrusion of dust, water vapor, corrosive gas and other impurities, and avoid oil leakage, ensuring stable operation in harsh environments such as high temperature, high humidity, dusty mines and outdoor construction sites. The rational internal oil circuit design and optional forced lubrication system ensure sufficient lubrication of all transmission components, enabling the product to work normally in the operating temperature range of -25℃ to +95℃.
6. Convenient Maintenance, Cost-Saving Operation
The modular design of the product makes the disassembly, assembly and maintenance of components more convenient, and the high interchangeability of spare parts reduces maintenance difficulty and time cost. The centralized oil filling port, oil drainage port and transparent oil level observation window facilitate daily lubrication management and oil level inspection. It is recommended to use 220#/320# heavy-duty industrial gear oil; the first oil change is after 600 hours of operation, and regular maintenance and oil change are performed every 6000 hours thereafter. The high reliability and long service life of the product effectively reduce the frequency of maintenance and replacement, lowering the total operation cost of customers.

V. Installation and Maintenance: Scientific Operation, Maximizing Performance
During installation, ensure that the coaxiality error between the reducer and the motor is ≤0.1mm and the parallelism error ≤0.08mm to avoid abnormal wear of gears and bearings caused by misalignment. Select the appropriate lubricating oil according to the working conditions: use 220# industrial gear oil for normal temperature and medium load, and 320# heavy-duty industrial gear oil for high temperature and heavy load. Regularly check the oil level and oil quality; replace the lubricating oil after the first 600 hours of operation, and perform comprehensive maintenance every 6000 hours thereafter, including checking gear meshing status, sealing performance, bearing temperature and tightening fasteners. If abnormal phenomena such as excessive noise, obvious vibration, oil leakage or overheating occur during operation, stop the machine immediately for inspection and troubleshooting to avoid further damage to the equipment.
