Guomao GX Series Planetary Speed Reducer Overview
Guomao GX Series Planetary Speed Reducer is a high-performance transmission device built on the classic NGW planetary gear structure, specially developed for heavy-load and precision transmission scenarios in the environmental protection industry and beyond. With its compact and lightweight design, exceptional load-bearing capacity and stable operation performance, it has become a core component in key environmental protection projects, providing reliable power support for efficient and continuous production operations.
In structural design, the GX Series features a scientific modular layout, which effectively reduces the overall volume and weight while maximizing torque output density. The housing is made of high-strength ductile iron, undergoing precision casting and heat treatment processes to ensure excellent rigidity, impact resistance and heat dissipation. This enables the reducer to adapt to the harsh working conditions of environmental protection equipment, such as frequent load changes and long-term continuous operation.
The core gear system is crafted from high-quality 20CrMnTi alloy steel, processed through gas carburizing, quenching and precision grinding. The tooth surface hardness reaches HRC58-62, and the gear accuracy is upgraded to Class 5, realizing smooth meshing, low wear and ultra-low noise operation. Its transmission efficiency is as high as 97% or more, minimizing energy loss and improving the overall operational efficiency of supporting equipment.
In terms of parameters, the GX Series covers a wide range to meet diverse needs, with a maximum input power of 132kW, a maximum output torque of 1830kN.m and a transmission ratio of up to 2522. It supports flexible installation modes and is perfectly matched with various motors. Widely applied in environmental protection fields such as food waste treatment, sewage disposal and solid waste processing, it also adapts to heavy-load scenarios in metallurgy and building materials industries, featuring easy maintenance and long service life.
