These reducers are designed for demanding applications requiring high torque, reliability, and modular flexibility. The series emphasizes advanced modular design, making it suitable for heavy-load machinery in industries such as mining, cement production, steel mills, and conveyor systems.
Compact and Lightweight: Modular design, small size and light weight, facilitate integration into space-constrained equipment.
High Reliability: Utilizing high-quality bearings and seals, and optimized oil flow, it withstands heavy-duty and demanding operating conditions with a low failure rate.
Easy Maintenance:Modular construction simplifies assembly and disassembly, as well as parts replacement, reducing maintenance time and costs.
Long Service Life: Precision machining and high-strength materials ensure a service life that reaches domestically advanced levels and offers exceptional durability.
Superior Performance: High torque output, efficient deceleration, excellent thermal and mechanical stability, and smooth operation.
High Cost-Effective: Optimizing heavy-duty performance and affordability, it is suitable for medium- and heavy-duty industrial applications.
1. What is the GM Series Reducer?
The GM Series is a line of modular cylindrical gear reducers optimized for heavy-duty use. It features a compact design with high torque output, suitable for applications requiring speed reduction and torque multiplication. The series includes 19 cabinet sizes, forming 64 reducer models, and is comparable to international brands like SEW in performance and reliability.
2. What are the key design standards and features?
Standards: Based on JB/T8853-2001 (Cylindrical Gear Reducer), JB/T9002-1999 (Transducer for Freighter), and GB/T10095.1-2001 (Involute Cylindrical Gear Accuracy).
Features: Modular combination design for small size, light weight, easy maintenance, and long service life. Includes extended bearing life, excellent oil circulation, and advanced sealing. Manufactured using tools like NILES grinding machines, OKUMA machining centers, and inspected with gear detection centers and 3D coordinate measuring instruments.
Advantages: High reliability from decades of design experience, reaching domestic advanced levels in mechanical, thermal, and performance properties.
3. What are the technical parameters and specifications?
Power Range: Typically 0.12 kW to 160 kW (varies by model; consult catalog for exact pairings).
Reduction Ratios: Common ranges from 1:5 to 1:400, depending on stages (single, double, or triple reduction).
Torque Output: Up to 50,000 Nm in larger models.
Mounting Options: Foot, flange, or shaft mount.
Lubrication: Oil bath standard; synthetic oils recommended for high loads. For precise specs, refer to the Guomao GM Series catalog.
4. What applications are GM Series reducers suitable for?
Ideal for heavy-duty industrial uses like conveyors, cranes, mixers, and freight elevators. They excel in environments needing robust power transmission, such as mining, metallurgy, and food processing, where downtime must be minimized.
5. How do I select the right GM Series reducer for my application?
Calculate required torque: Output torque = Input power × 9550 / Input speed (in rpm).
Factor in service factor (1.0-2.5 based on load type: uniform, variable, or shock).
Use reduction ratio to match motor speed to load requirements.
Consider thermal ratings for continuous duty. Guomao provides selection software and charts; input motor HP, desired output speed, and load type for recommendations.
6. What maintenance is required for GM Series reducers?
Daily/Weekly: Check oil levels and listen for unusual noises.
Monthly: Inspect seals, vents, and mounting bolts for tightness.
Annually: Change oil (use ISO VG 220-320 grades), clean filters, and align shafts.
