The Guomao GM series heavy-duty gear reducer is engineered for continuous heavy-load operation, frequent startup and variable impact load working conditions. Precision carburized and ground hard tooth surface gears deliver outstanding contact fatigue resistance, bending strength and wear resistance, which can cope with instantaneous torque spikes from heavy machinery startup and operation. Covering an ultra-wide speed ratio range from 1.3 to 33000, this series realizes ultra-high speed reduction and near-direct drive low reduction output, meeting diversified speed matching demands of various industrial equipment. The casing adopts an integrated rib reinforcement design to improve overall structural rigidity, effectively restrain vibration and noise during long-time full-load operation, protecting bearings and gear pairs from fatigue damage. The split upper and lower box structure facilitates routine inspection, gear maintenance, bearing replacement and periodic oil change, minimizing production line downtime caused by equipment maintenance. Optimized internal oil circuit and heat dissipation structure stabilize the internal working temperature under sustained heavy-duty operation, avoid high-temperature degradation of lubricating oil and sealing components, and extend the overall service life of the gearbox. High-strength bolt fasteners are used for all flange connections to maintain stable sealing and structural reliability under long-term alternating loads. With a peak output torque up to 50kN·m, it maintains stable torque output under short-time overload conditions.
GM series industrial gear reducer is widely used as main drive transmission equipment for bulk material conveying, mining machinery, metallurgical equipment, concrete mixing, grain processing and port handling machinery. Typical application scenarios include heavy-duty belt conveyors, bucket elevators, mining crushers, metallurgical roller tables, concrete mixers, port stacker-reclaimers, biomass pellet extruders and large industrial stirring equipment. Benefiting from the ultra-wide speed ratio coverage and flexible power matching from low-power fine drive to medium-power heavy drive, it also fits precision automation equipment, packaging machinery, food processing equipment, environmental protection stirring devices and light industrial transmission equipment. It provides stable low-speed high-torque or high-efficiency medium-speed power output for general heavy-duty production lines in chemical industry, building materials and environmental protection fields.
