Description

S-Series Helical Worm Gear Reducer: Efficient Transmission, Accurately Empowering Industrial Upgrades

I. Product Overview: Innovative Design, Reshaping Transmission Experience

Weigao’s S-Series Helical Worm Gear Reducer is a high-precision speed reduction unit integrating helical gear and worm transmission technologies, tailor-made to fulfill the power transmission demands of industrial machinery. Embracing a modular design concept, this product skillfully merges the efficient meshing capability of helical gears with the large reduction ratio merit of worm transmission. It not only resolves the drawbacks of traditional reducers, such as bulky size and high energy consumption, but also maintains stable output in low-speed and heavy-load applications. Boasting a compact structural arrangement, superior transmission efficiency, and broad adaptability, it serves as a core power component in sectors like automated production lines, logistics and conveying equipment, and construction machinery, offering solid support for the efficient and intelligent transformation of industrial production. As a flagship export product of Weigao, this reducer series has been distributed to over 80 countries and regions worldwide, securing widespread acclaim from global clients.

II. Core Advantages: Four Highlights, Defining Transmission Benchmarks

1. High Efficiency & Energy Saving, Low Transmission Loss

Crafted from premium alloy materials and processed via precision gear grinding techniques, the helical gears and worms achieve meshing accuracy compliant with GB/T 10095.2 Class 6 standards. This ensures a transmission efficiency of 92%-96%, cutting energy consumption by 15%-20% compared to conventional worm reducers. The distinctive helical tooth profile design mitigates meshing impact and noise, keeping operational noise below 75dB and fostering a quiet workshop environment.

2. Stable Heavy-Load Performance, Strong Load-Bearing Capacity

The worm features a multi-start right-hand rotation design, enabling multi-point contact transmission with helical gears. This design increases the contact area by 30% compared to traditional structures, with a rated output torque ranging from 50N·m to 5000N·m, allowing it to effortlessly handle severe working conditions like low-speed heavy loads and frequent start-stop cycles. The casing is produced through an integrated cast iron casting process, boasting high rigidity and excellent seismic performance. It effectively disperses stress concentration during transmission, thereby prolonging the product’s service life.

3. Flexible Adaptability, Easy Installation

This product provides diverse installation options, including horizontal, vertical, and flange mounting. The output shaft can be configured with flat key, spline, or hollow shaft structures, compatible with motor power ranging from 0.12kW to 75kW and a reduction ratio of 5 to 1000. It can be flexibly combined based on the power requirements of different equipment. The modular design of its components simplifies subsequent maintenance and replacement, lowering equipment downtime costs.

4. Corrosion & Wear Resistance, High Reliability

Key transmission components undergo surface carburizing and quenching treatment, reaching a hardness of HRC 58-62, which endows them with exceptional wear and corrosion resistance. The sealing system adopts a double skeleton oil seal + labyrinth seal configuration, achieving an IP54 protection level (IP65 available upon customization). This effectively prevents the ingress of dust and oil contamination, making it suitable for harsh industrial environments. With proper maintenance, the service life can exceed 10 years.

III. Application Fields: Comprehensive Coverage, Empowering Multi-Industry Development

Thanks to its multi-scenario adaptability, Weigao’s S-Series Helical Worm Gear Reducer has been extensively utilized across various industrial sectors:

Automated Equipment: Robot joints, automated production lines, manipulators, etc., delivering precise speed control and power output;

V. Installation and Maintenance: Scientific Operation, Extending Equipment Life

During installation, ensure the coaxiality error between the reducer and the motor is ≤0.1mm to avoid component wear caused by transmission deviation. Regularly inspect the lubricating oil level; 220# medium-load industrial gear oil is recommended. Replace the oil after the initial 500 hours of operation, and conduct maintenance every 5000 hours thereafter. If the equipment generates abnormal noise or vibration, shut it down immediately for inspection, focusing on the gear meshing condition and sealing system to ensure stable equipment operation.

VI. Conclusion: Driven by Quality, Empowered by Innovation
