The product features stable transmission, low noise, compact structure, and strong adaptability, capable of stably operating in temperature ranges from -10℃ to +40℃. It is widely applied in textile, food, packaging, machine tool feeding, and light industrial conveying equipment, providing efficient and reliable power transmission support for global general industrial production lines.
II. Core Advantages
1. Precision Helical Bevel Gear Transmission, Stable & Low Noise
Adopting one-stage precision helical bevel gear transmission design, the gear unit achieves accurate 90° right-angle power conversion with actual transmission ratios of 1:1, 1.5:1, 2:1, 2.5:1, and 3:1 for flexible selection. Gears are made of high-quality 20CrMnTi alloy steel, processed by carburizing and quenching, and precision grinding, with tooth surface hardness reaching HRC 58-62 and roughness ≤Ra 0.8μm. The optimized tooth profile design ensures a meshing contact area of over 95%, effectively reducing transmission impact and noise. The no-load operating noise is ≤65dB at 1m distance, and the transmission efficiency is as high as 94%-96%, realizing energy-saving and quiet operation for general industrial equipment.
2. Standard B14 Flange Mounting, Modular & Flexible Adaptation
The unit adopts standardized B14 flange mounting design, with flange interface complying with IEC international standards, enabling direct and reliable connection with motors and driven equipment without additional adapter brackets. The modular housing structure supports multiple configuration combinations, including single horizontal shaft, double horizontal shaft, single vertical shaft, and double vertical shaft, fully adapting to different layout requirements of industrial production lines. The compact overall design reduces installation space occupation by 30% compared with traditional right-angle reducers, making it especially suitable for equipment with limited installation space such as small conveyors and precision machine tools.
3. High-Rigidity Cast Iron Housing, Reliable & Durable
The housing is made of high-quality HT250 cast iron, formed by integral casting and precision machining, ensuring excellent structural rigidity and impact resistance. Key stress-bearing parts are optimized through structural simulation, effectively dispersing transmission loads and avoiding housing deformation under rated working conditions. The surface is treated with anti-rust and anti-corrosion painting, which can adapt to general industrial environments such as dust and moderate humidity. Equipped with high-precision deep groove ball bearings, the shaft system operates stably with a service life of more than 20,000 hours under normal working conditions, ensuring long-term reliable operation of the transmission system.
4. Integrated Lubrication System, Convenient Maintenance
The gear unit adopts integrated oil bath lubrication design, with factory-filled special extreme pressure gear oil, enabling immediate use after installation. The housing is equipped with a transparent oil level observation window, a centralized oil filling port, and a quick-opening oil drain port, facilitating daily lubrication inspection and oil change operations. The lubrication system is optimized for long-term operation, with a recommended oil change cycle of 4000 hours under normal working conditions, greatly reducing maintenance frequency and downtime cost. Sealing parts adopt high-temperature and wear-resistant oil seals, effectively preventing oil leakage and ensuring clean operation environment.
III. Typical Application Fields
- Textile Industry: Textile machine transmission systems, yarn winding machine driving mechanisms
- Food & Packaging Industry: Automatic packaging machine conveying systems, food processing line driving devices
- Machine Tool Industry: Precision machine tool feeding systems, small machine tool auxiliary transmission mechanisms
- Light Industry Conveying: Small belt conveyor drives, assembly line transmission systems

V. Installation & Maintenance
Adopt B14 flange standardized installation, ensure the flatness of the mounting surface ≤0.02mm/m to avoid additional stress on the shaft system. During installation, check the coaxiality between the input/output shaft and the connected equipment to ensure smooth transmission. Select appropriate lubricating oil according to the working environment: use 220# extreme pressure industrial gear oil for normal temperature conditions. Regularly check the oil level through the observation window, and replace the lubricating oil every 4000 hours of operation or once a year. Keep the surface of the housing clean to facilitate heat dissipation. Stop the machine immediately for inspection if abnormal noise, oil leakage, or excessive temperature rise occurs during operation.
