12 Ton Traveling Device Mining Locomotive Wheel Set Leaf Spring Suspension Integrated Gearbox

12-ton mining locomotive wheel set is a complete drive assembly engineered for underground rail haulage and industrial track transportation. Designed for 12-ton battery or trolley locomotives, this integrated unit combines the wheel pair, two-stage reduction gearbox, large and small bevel gears, and wheel flange into a single robust assembly. Manufactured from high-strength alloy steel with precision machining and heat treatment, it delivers reliable torque transmission, high load-bearing capacity, and long service life under the demanding conditions of mining and tunnel operations.

The wheel set assembly is manufactured through a series of precision processes: alloy steel billets are forged and normalized to relieve internal stresses; wheel blanks are machined on CNC lathes to achieve the Φ680 mm rolling circle diameter and flange profile; bevel and spur gears are cut on precision gear hobbing machines, then carburized and hardened to achieve surface hardness of HRC 58-62 while maintaining a tough core; the gearbox housing is cast or fabricated from steel plate and precision-machined for bearing bore alignment; all components are assembled with heavy-duty bearings, seals, and lubricated for long-term operation; the completed assembly undergoes run-in testing to verify smooth rotation, proper gear meshing, and leak-free sealing.
