Guomao ZLY Series Hard Tooth Surface Cylindrical Gear Reducer

Guomao ZLY Series is a high-performance hard tooth surface cylindrical gear reducer specifically engineered for heavy-load and high-speed industrial scenarios. As a core transmission component in heavy industries, it integrates robust structural design, precision manufacturing technology and reliable performance, providing stable and efficient power transmission support for large-scale industrial equipment operating under harsh conditions.

In terms of structural design, the ZLY Series adopts a one-piece housing made of HT200 high-strength cast iron. After precision casting and aging treatment, the housing effectively eliminates internal stress, ensuring excellent rigidity, impact resistance and heat dissipation capacity. This enables the reducer to withstand strong vibrations and heavy loads during long-term operation without deformation. The core gear system is crafted from high-quality 20CrMnTi alloy steel, which undergoes strict gas carburizing, quenching and precision grinding processes. The tooth surface hardness reaches HRC58-62, and the gear accuracy is upgraded to Class 5, realizing smooth meshing, low wear and reduced operating noise.

In performance, the series boasts outstanding indicators that meet heavy-industry demands. Its per-stage transmission efficiency is no less than 96%, minimizing energy loss and improving the overall operational efficiency of the supporting equipment. It covers a wide parameter range, with input power from 0.75kW to 160kW, maximum output torque up to 20,000N.m, and a transmission ratio range of 8 to 400, which can be flexibly combined to meet extreme low-speed and high-torque operation requirements. Equipped with a multi-layer sealing structure, it achieves an IP54 protection level, effectively preventing oil leakage and the intrusion of dust, moisture and other impurities.

The ZLY Series supports flexible installation modes such as foot mounting and flange mounting, easily matching with three-phase asynchronous motors, frequency conversion motors and other power units. It is widely applied in metallurgy, mining, building materials, transportation and chemical industries, perfectly adapting to conveyors, mixers, crushers and other heavy-duty equipment. Backed by strict factory testing, its main components have a service life of over 20,000 hours, featuring convenient maintenance and low operating costs, making it a cost-effective transmission solution for heavy industries.
