Guomao Reducer GK Series Geared Motor Introduction
Guomao GK Series Geared Motor is a high-performance transmission device integrating helical and spiral bevel gear technology, designed for multi-industry power transmission needs. With its compact structure, high efficiency and flexible installation, it has become a reliable choice for precision transmission in harsh working conditions, delivering stable power support for various industrial equipment.
Core Structural Advantages
The GK Series adopts a highly modular design, enabling flexible matching with various 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 two-stage helical gears and one-stage spiral bevel gears, processed through gas carburizing, quenching and precision grinding, which enhances tooth surface hardness and wear resistance.
Outstanding Performance Metrics
- High efficiency and low noise: The single-unit gear efficiency is no less than 95%, with precision-machined components and meticulous assembly reducing operating noise significantly.
- Wide parameter range: It covers an input power of 0.12-200kW, a maximum output torque of 18,000N.m, and a transmission ratio range of 1.26-33,000, achieving extremely low output speeds through combined units.
- Strong load capacity: It can withstand large radial loads and axial loads up to 15% of the radial force, adapting to heavy-load operation scenarios.
- Stable adaptability: Suitable for ambient temperatures of -10℃ to 40℃ and altitudes below 1,000 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, flange mounting and shaft mounting. The series offers 12 models such as GK (solid shaft, foot-mounted), GKF (solid shaft, B5 flange-mounted) and GKA (hollow shaft, shaft-mounted), along with derivative types with anti-rotation arms. It is widely used in environmental protection, food processing, packaging, metallurgy, machinery tools, photovoltaic and medical industries, powering conveyors, lifting devices, mixers and other key equipment.
Backed by strict factory testing and mature manufacturing processes, the GK Series ensures a main component service life of no less than 20,000 hours under proper use. It combines reliability, efficiency and cost-effectiveness to provide high-quality transmission solutions for global industrial customers.
