Engineering Advantages
Quiet, Smooth Transmission: Precision helical tooth geometry ensures progressive mesh engagement, reducing operating noise and vibration.
High Mechanical Efficiency: Up to 96% or higher per gear stage, reducing operating energy costs.
Extensive Ratio Flexibility: Ratios up to 33,000 cover applications ranging from high-speed mixers to ultra-low-speed heavy conveyors.
Robust Thermal & Load Capacity: High-grade alloy gearing and heavy-duty housing materials dissipate heat rapidly and absorb shock loads.
Global Interchangeability: B5 flange dimensions align with international mounting standards for easy replacement of existing gear units.
Industry Applications
Belt & Screw Conveyors: Controlled speed and steady continuous torque for bulk material handling.
Bucket Elevators & Hoists: Reliable vertical power transmission under heavy starting loads.
Mixers & Agitators: High output torque capability for continuous fluid and chemical processing.
Material Transfer Systems: Compact drive design for automated warehouse transfer cars and turntables.
Industrial Processing Equipment: Custom machinery requiring motor speed reduction with high mechanical efficiency.
Gearbox Stages
Single-Stage
Designed for lower reduction ratios requiring higher output speeds and compact overall length.
Two-Stage
Balances moderate reduction ratios with high mechanical efficiency across general industrial machinery.
Three-Stage
Engineered for high reduction ratios, generating maximum torque multiplication and low output speeds.
Output Shaft Options
Solid Output Shaft
Machined with standard keyway; ideal for coupling connections, chain sprockets, V-belt pulleys, and spur gears.
Hollow Output Shaft
Enables direct shaft-mounting onto the driven machine shaft, saving space and eliminating external couplings.
Motor Electrical Options
Motors are modularly paired with the gearbox to match regional power grids and severe duty environments:
Configurable for global power supplies (230/400V, 460V, 575V at 50Hz or 60Hz).
Windings reinforced for variable-frequency drive operation across wide speed ranges.
IP55 standard for dust and water resistance; IP65/IP66 available for washdown environments.
Spring-applied DC electromagnetic brakes, forced cooling fans for low-speed VFD operation, and integrated PTC/PT100 thermistors.
Quality Control
Quality and reliability depend on strict manufacturing controls across all processing stages:
Gear Cutting & Carburizing: Gears are cut from high-grade 20CrMnTi alloy steel and case-hardened to achieve superior surface hardness (58 to 62 HRC) and a tough ductile core.
Precision Gear Grinding: Tooth flanks are CNC ground to ISO Class 5/6 precision, minimizing backlash and operational noise.
Housing & Shaft Machining: Machined on CNC horizontal machining centers to maintain precise centerline concentricity and bearing seat tolerances.
Assembly & Final Inspection: 100% of assembled units undergo oil-leak checks, running noise audits, vibration checks, and dimensional verification prior to packaging.
OEM Customization & Drop-In Replacements
Direct Replacement Support: For existing installations, provide the nameplate data, existing model code, or photo. Dimensionally equivalent units can be configured for direct drop-in replacement.
OEM Design Support: Full 2D dimensional outlines and 3D STEP files are supplied for seamless integration into customer CAD assemblies prior to ordering.
Final Inspection, Protective Packaging & Delivery
Pre-Shipment Verification: Inspection checks confirm exact gear ratio, motor electrical ratings, flange tolerances, keyway alignment, direction of rotation, and factory oil fill levels.
Export Packaging: Machined flange faces and shaft extensions receive anti-rust coatings and protective covers. Gearmotors are packaged in heavy-duty export plywood cases or palletized with heat-shrink wrap suitable for long-distance ocean and air freight.
Technical FAQ
Q: What information is required to get an immediate technical quote?
A: Provide motor power (kW), required output speed (or ratio), output torque, B5 flange size, shaft type (solid/hollow), operating voltage/frequency, and order quantity.
Q: Can you provide 3D CAD models before we place an order?
A: Yes. STEP and IGES 3D CAD files, along with 2D dimensional drawings, can be provided upon request for engineering verification.
Q: Are your gear motors compatible with Variable Frequency Drives?
A: Yes. All motors can be ordered with inverter-duty insulation (Class F/H) and optional forced cooling fans for continuous low-speed VFD operation.
Q: Can you match standard international brands for direct replacement?
A: Yes. Our engineering team can cross-reference mounting dimensions, shaft extensions, ratios, and motor frame sizes to provide a direct drop-in replacement unit.
