Guomao Reducer GS Series Geared Motor Introduction
Guomao GS Series Geared Motor is a high-performance transmission device integrating helical gear and worm gear technology, designed for multi-industry precision power transmission. With its compact vertical structure, reliable performance and flexible adaptability, it has become a trusted choice for equipment requiring space-saving and stable operation, providing efficient power support for various industrial scenarios.
Core Structural Advantages
The GS Series adopts a highly modular design, enabling flexible matching with various types of motors and power input devices. The same model can be adapted to multiple power motors, and easy combination between different models meets diverse transmission requirements. Its housing is made of high-strength cast iron, ensuring excellent load-bearing capacity and impact resistance while maintaining a compact volume. The gear system consists of one-stage helical gears and one-stage worm gears—gears and shafts undergo gas carburizing, quenching and precision grinding, with tooth surface hardness reaching HRC58-62, while worms use high-wear-resistance alloys, significantly enhancing durability.
Outstanding Performance Metrics
Efficient and low-noise operation: The single-unit transmission efficiency reaches up to 89%, with precision-machined components and meticulous assembly ensuring smooth operation and low noise.
- Wide parameter range: It covers an input power of 0.12-22kW, a maximum output torque of 4200N.m, and a fine-divided transmission ratio range of 1.26-33000, achieving extremely low output speeds through combined units.
- Strong load capacity: It can withstand large radial loads and axial loads up to 10% of the radial force, adapting to heavy-load operation scenarios.
- Stable environmental adaptability: Suitable for ambient temperatures of -10℃ to 40℃ and altitudes below 1000 meters, supporting forward and reverse operation without industry restrictions.
Flexible Installation & Wide Applications
Installation is not limited by position, with multiple options including foot mounting (GS type), flange mounting (GSF type), hollow shaft mounting (GSA type) and combined flange-hollow shaft mounting (GSAF type). Derivative models such as input shaft type and anti-rotation arm-equipped type further expand application scenarios. It is widely used in food processing, packaging machinery, environmental protection equipment, logistics conveyors and medical devices, relying on long service life (main components ≥20000 hours) and easy maintenance to reduce user operating costs.
