NGC MHB Series Standard Industrial Gearbox Introduction

The MHB Series Standard Industrial Gearbox, developed by Nanjing High Speed Gear (NGC) on a dedicated modular platform, represents a leap forward in heavy-duty power transmission solutions. Engineered to address the drawbacks of traditional gearboxes—such as bulkiness and oil leakage—this series integrates advanced design concepts and precision manufacturing, delivering exceptional performance across harsh industrial environments.

At its core, the MHB Series adopts a modular design philosophy, enabling high interchangeability of key components and flexible customization. This design not only shortens delivery cycles but also reduces maintenance costs significantly. Compared with conventional counterparts, it achieves a 25%-30% weight reduction under the same power transmission capacity, optimizing host equipment design and lowering overall ownership costs for manufacturers and end-users.

Precision is paramount in the MHB Series. Gears are crafted from high-quality alloy steel, undergoing carburizing, quenching, and precision grinding processes. Advanced tooth profile and helix modification technologies ensure uniform load distribution, while root shot peening enhances bending strength. These features collectively boost load-carrying capacity, minimize noise and vibration, and extend service life. The series complies with international standards including ISO1328-1995 for gear accuracy, ISO6336-2006 for strength calculation, and ANSI/AGMA6010-E88, guaranteeing global compatibility.

Key technical parameters of the MHB Series are tailored for versatility: torque range of 6.6–470 kN.m, speed ratio of 14–250, and center distance of 405–1,980 mm. It supports multiple mounting configurations (horizontal/vertical) and output modes (solid/hollow shaft), with optional accessories like backstops, oil heaters, and cooling systems to meet diverse operational needs. Enhanced sealing structures prevent oil leakage and dust ingress, adapting to high-dust, heavy-load conditions.

Widely adopted in material handling and metallurgy industries, the MHB Series has proven its reliability in blast furnace feeding systems, slag conveying lines, and mine belt conveyors for giants like Baoshan Iron & Steel and Shenhua Group. It seamlessly replaces outdated ZY/DY series gearboxes without modifying installation dimensions, offering a cost-effective upgrade path. With a design life of 10 years and consistent performance in -40℃ to +45℃ environments, the MHB Series stands as a benchmark for durable, efficient industrial gearboxes.
