Key Advantages
Space-Saving Parallel Layout: Offers a slim, compact envelope along the driven axis, permitting installation where right-angle or inline space is restricted.
High Torque Density: Delivers up to 21,477 N·m, offering a wide engineering window from light automation to heavy processing.
Broad Ratio Spectrum (3.77–228.9): Precise reduction steps allow exact output speed tuning without over-sizing the drive motor.
High Interchangeability: Standardized footprint and shaft dimensions match international leading brands for seamless field replacements.
Flexible Modular Customization: Compatible with standard IEC motors, brake motors, variable frequency drives (VFD), and specialized dual-voltage configurations.
Industry Applications
Material Handling & Logistics: Belt conveyors, roller tracks, chain conveyors, sorters, and transfer systems.
Bulk Material Machinery: Bucket elevators, screw feeders, and continuous drag chain systems.
Packaging & Automated Machinery: Footprint-restricted automated assembly lines, packaging machinery, and palletizers.
Metal Processing & General Industry: Agitators, industrial mixers, auxiliary drives, and metal processing equipment.
Output Shaft Options
Solid Output Shaft: Machined with standard keyways for rigid couplings, chain sprockets, belt pulleys, and external gear drives.
Hollow Output Shaft: Allows direct slip-on mounting onto the driven machine shaft, eliminating flexible couplings and saving axial space.
Shrink Disc Connection: Optional heavy-duty, keyless clamping element for hollow-shaft configurations, providing zero-backlash torque transmission and easy removal.
Mounting Options
Foot Mounting: Rigid base connection for machinery featuring a dedicated gearbox platform.
Flange Mounting: Direct bolt-circle flange attachment for enclosed machine housings or vertical drive setups.
Shaft-Mounted Installation: Suspended installation directly on the driven shaft, supported by a torque arm to absorb reaction forces-ideal for belt and chain conveyors.
Step-by-Step Engineering Selection Process
Define Operating Parameters: Confirm required input motor power (kW), motor speed (rpm), required output speed (rpm), and continuous/peak output torque (N·m).
Calculate Reduction Ratio: Transmission Ratio = Input Motor Speed / Required Output Speed (1,500 rpm motor ÷ 30:1 ratio ≈ 50 rpm output speed).
Verify Overhung / Shaft Loads: Calculate external radial and axial loads for belt, chain, or sprocket drives to verify bearing lifetime.
Evaluate Operating Conditions: Account for daily operating hours, starting frequency, shock loads, and ambient temperatures.
Select Mechanical Configuration: Choose output shaft style (solid/hollow), mounting method (foot/flange/shaft-mount), and motor options (e.g., brake motor, inverter duty).
OEM Capabilities
We provide comprehensive configuration flexibility tailored to global OEM requirements:
Electrical Options: Custom voltage/frequency (220V–690V, 50Hz/60Hz), IP55/IP66 enclosure, Class F/H insulation, IE3/IE4 premium efficiency motors, brake motors, and forced-cooling blowers.
Mechanical Modifications: Custom shaft diameters/lengths, special flange dimensions, custom torque arms, and high-temperature or food-grade oil seals.
Surface Protection: Multi-coat epoxy paint systems for corrosive, high-humidity, or outdoor industrial environments.
Quality Control
Gear Tooth Inspection: Precision testing on automated gear measuring centers to verify profile, pitch, and lead accuracy.
Dimensional Alignment: Housing bore tolerances, shaft alignment, and bearing fits are measured via coordinate measuring equipment before assembly.
Assembly Validation: Gear mesh contact patterns and backlash clearances are verified prior to housing closure.
No-Load Running Test: 100% of finished units undergo bench running tests to measure noise, vibration, seal integrity, and oil tightness.
Final Pre-Shipment Audit: Full inspection against customer PO specs, electrical voltage, and nameplate markings.
Export Packaging Standards
Anti-rust oil treatment applied to all exposed steel shafts and mounting surfaces
Sealed protective moisture-proof plastic wrapping.
Reinforced IPPC-certified ISPM15 fumigation-free wooden cases for international sea/air freight.
Frequently Asked Questions
Q: What is the warranty period for the G Series Geared Motor?
A: We provide an 18-month warranty (or 12 months from machine commissioning) backed by complete technical support and spare parts supply.
Q: Can you provide 3D CAD models before placing an order?
A: Yes. Our engineering team provides STEP or IGES files within 24 hours to help you confirm mechanical space and mounting compatibility.
Q: What is your standard lead time for batch orders?
A: Standard configurations ship in 10–15 business days. Customized or OEM batch orders typically ship in 20–25 business days.
Q: Can these gearmotors be operated with Variable Frequency Drives?
A: Yes. All motors can be equipped with inverter-duty windings and independent cooling fans for low-speed, high-torque continuous operation under VFD control.
