With its strong universality, wide compatibility and high cost performance, it has become a core transmission component in industries such as general manufacturing, light industrial processing, ventilation and water supply, and packaging machinery, providing reliable and economical power support for the standardized and efficient upgrading of industrial production. As a mainstream export product of Weigao, this series has been sold to more than 80 countries and regions around the world, winning widespread recognition from global customers with its stable and reliable general performance.
II. Core Advantages: Five Core Strengths, Creating Universal Transmission Benchmarks
1. Efficient Transmission, Energy-Saving Operation
Adopting precision-ground helical gears with mature tooth profile optimization technology, the series achieves meshing accuracy up to GB/T 10095.2 Class 6 standard. The parallel axis transmission structure with optimized center distance ensures smooth gear meshing, with transmission efficiency reaching 93%-96% for two-stage transmission and 91%-94% for three-stage transmission, effectively reducing energy loss compared to traditional general-purpose reducers. The smooth meshing characteristics of helical gears minimize operating noise, with the noise level ≤75dB at 1m distance, creating a comfortable working environment for general workshops.
2. Model-Specific Positioning, Strong Universality
The two core models of the series have clear positioning to cover general transmission needs: F models are designed for standard general-load scenarios, with a lightweight housing structure, suitable for most general manufacturing equipment such as small conveyors and fans; FA models adopt a compact flange-mounted design, optimizing the installation space, ideal for equipment with limited layout space such as packaging machinery and small processing machines. The standardized design of the two models ensures strong compatibility with mainstream motors and auxiliary components in the market, realizing quick matching and application.
3. Reliable Load-Bearing, Durable Operation
Gears and transmission shafts are made of high-quality 40Cr alloy steel, processed through carburizing, quenching and precision grinding processes. The surface hardness reaches HRC 58-62, and the core hardness is HRC 30-35, ensuring good wear resistance and fatigue strength. The optimized gear tooth width design increases the effective meshing area by 30% compared to traditional general-purpose models, with rated output torque ranging from 50N·m to 5000N·m. The one-piece cast iron housing with reasonable rib layout has good structural rigidity and shock absorption capacity, which can effectively disperse transmission stress and ensure a service life of more than 10 years under normal maintenance and general load operation conditions.
4. Simple Installation, Flexible Configuration
The series supports mainstream installation modes in the market, including base-mounted and flange-mounted (B5/B14), which can be flexibly selected according to equipment layout requirements. The output shaft is configured with a standardized solid shaft with flat key or spline solid shaft, which is compatible with motors with power ranging from 0.12kW to 75kW and reduction ratios of 2.5-300 (two-stage/three-stage combination). The standardized interface design facilitates quick connection with motors and working machines, reducing installation difficulty and time cost.
5. Easy Maintenance, Cost-Effective Operation
Equipped with a reliable double-lip oil seal + O-ring sealing system, the reducer achieves IP54 protection level, which can effectively prevent the intrusion of dust and water vapor in general industrial environments and avoid oil leakage. The internal oil circuit is reasonably designed to ensure sufficient lubrication of transmission components, and the product can work normally in the operating temperature range of -20℃ to +85℃. The modular design makes component disassembly and maintenance simple; centralized oil filling and drainage ports facilitate lubricating oil replacement. It is recommended to use 220# general industrial gear oil, with the first oil change after 500 hours of operation and regular maintenance every 5000 hours thereafter. The high universality of spare parts and low maintenance cost effectively reduce the total operation cost of customers.
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# general industrial gear oil; the first oil change is after 500 hours of operation, and regular maintenance and oil change are performed every 5000 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 caused by misalignment. It is recommended to use 220# general industrial gear oil for lubrication; check the oil level regularly to ensure it is within the standard range. Replace the lubricating oil after the first 500 hours of operation, and perform comprehensive maintenance every 5000 hours thereafter, including checking gear meshing status, sealing performance and tightening fasteners. If abnormal phenomena such as excessive noise, overheating or oil leakage occur during operation, stop the machine immediately for inspection and troubleshooting to avoid further damage to the equipment.
