Product Characteristics
Integrated Cast Housing For Ultra-High Torque
Thick ductile iron monoblock casting with full reinforcing ribs. Reinforced thickened flange & output shaft. Multiple planet gears evenly share loads, supporting heavy torque up to thousands kN·m and sudden shock loads.
Multi-Stage Combined Modular Design
Combinable 2/3 planetary stages with optional front helical or bevel reduction unit. Ratio range 25–4000, frame sizes 16 to 34 complete. Heavy-duty hollow shaft, solid shaft and spline output versions available.
Independent Forced Circulation Lubrication
Standard external oil pump with dedicated cooling circuit, circulating industrial grease for extreme temperatures. Vertical and heavy horizontal units equipped with separate oil compensation tank to prevent dry abrasion of far-end bearings inside large housing.
Product advantages
High Torque Density For Heavy Machinery
Delivers several times higher torque than worm and parallel shaft reducers with identical dimensions. Ideal for mining conveyors, large mixers, stacker-reclaimers and port cranes; single unit replaces multiple small gearboxes.
Stable Round-The-Clock Operation
Thick hardened gears and large oil chamber provide sufficient heat dissipation. No rapid grease degradation under 24/7 full-load operation, cutting heavy production line downtime and economic loss.
Complete Heavy-Duty Industrial Attachments
Matched heavy-duty torque arms, oversized support bases and thick motor adapter flanges. Compatible with high-power asynchronous, variable frequency and servo motors for high reaction force & big radial load conditions.

FAQ
Q:Can large planetary gearbox withstand frequent shock start-stop?
A:es. Multiple planets distribute impact stress and cast housing resists deformation. Double-sided heavy torque arms are recommended under extremely violent shock conditions.
Q:What key parameters should be checked when selecting large reducers?
A:Focus on rated output torque, peak shock torque, thermal capacity and allowable radial load of output shaft. Heat dissipation calculation is essential for high temperature and high duty cycle environments.
Q:What heavy machinery uses large planetary gearboxes?
A:Large belt conveyors, vertical & horizontal mixing tanks, mining mill auxiliary drives, port stacker-reclaimers, heavy automated warehouses, cement conveying equipment and lifting winch mechanisms.
