Performance Advantages

High Energy Efficiency: Helical-worm combined gearing minimizes sliding friction, delivering significantly higher thermal capacity and drive efficiency than standard worm drives.

Smooth & Quiet Operation: Precision-ground gearing reduces operational noise, vibration, and backlash.

Wide Speed & Ratio Coverage: Multiple gear ratio combinations achieve precise output speeds down to 0.04 r/min.

Compact Integrated Assembly: Directly coupled motor and gearbox housing save valuable footprint within machine frames.

Industrial Applications

Belt & Screw Conveyors

Stable speed reduction and continuous output torque for bulk handling.

Agitators & Industrial Mixers

High radial load capacity suitable for fluid and powder agitation.

Bucket Elevators & Hoists

Reliable power transmission for vertical material lift mechanisms.

Drying & Rotating Drums

Smooth, controlled low-speed rotation under variable process loads.

Paper & Packaging Machinery

Quiet operation and precise power delivery for processing equipment.

Water & Wastewater Treatment

Heavy-duty drives for water screws, clarifiers, and surface aerators.

Mounting Positions & Output Configurations

Select the mechanical connection style that matches your driven equipment layout:

Solid Shaft: Ideal for direct connection using external flexible couplings, sprockets, pulleys, or gear wheels.

Hollow Shaft (Keyed): Allows direct shaft-mounted installation onto the driven machine's input shaft to save installation space.

Shrink Disc Connection: Heavy-duty hollow shaft option for keyless, backlash-free clamping torque transmission.

Flange Mounting

B5 or B14 output flanges for direct bolt-on connection to machinery walls or agitator housings.

Foot Mounting

Traditional bottom foot-mounted configuration for rigid bedplate attachment.

Torque Arm

Supports reaction torque on shaft-mounted configurations, reducing stress on driven machine bearings.

Custom Engineering

We offer tailored engineering for OEM machine builders and specialized project replacements:

Customized output shaft lengths, diameters, and spline profiles
Non-standard mounting flange dimensions and bolt patterns
Specialized electrical options: Brake motors, variable frequency drives (VFD duty), multi-voltage inputs
Heavy-duty synthetic lubrication for extreme low/high ambient temperature environments
Custom anti-corrosion paint coatings for marine or chemical exposure
Specialized mechanical interface designs based on customer 2D/3D machinery drawings

Quality Assurance

Quality control checks are integrated into every phase of assembly:

Incoming Inspection

Metallurgical and dimensional testing of raw gear blanks and housing castings.

In-Process Checks

Gear tooth profile and lead measurements via automated gear inspection centers.

Assembly Control:

Controlled bearing preload and backlash settings during gearbox build.

Final Performance Testing

100% of finished units undergo no-load running checks to measure noise, vibration, seal integrity, and temperature rise.

Export Packaging

Protective Coatings

Exposed shafts and machined surfaces are treated with anti-rust oil and shrink-wrapped.

Moisture Protection

Sealed plastic wrapping with desiccant packs prevents corrosion during ocean transit.

Structural Packaging

Heavy-duty, ISPM-15 compliant export wooden cases or reinforced steel-band pallets prevent movement.

Project Logistics

Clear shipping marks, lifting indicators, and custom packing slips support rapid customs clearance.

Frequently Asked Questions

Q: What power range and frame sizes does the G Series cover?

A: The G Series covers motor power ratings from 0.12 kW up to 30 kW across frame sizes GS37, GS47, GS57, GS67, GS77, GS87, GS97, and GS100.

Q: Are G Series gearboxes dimensionally compatible with major European gear motor brands?

A: Yes, the G Series utilizes standardized shaft, footprint, and flange dimensions, making it a direct drop-in replacement for standard international helical-worm gearboxes.

Q: Why choose a helical-worm gearbox over a standard single-stage worm gearbox?

A: Combining an initial helical gear stage with a secondary worm stage significantly reduces sliding friction loss. This results in up to 30% higher mechanical efficiency, reduced heat generation, and lower power consumption.

Q: Can I request 2D/3D CAD models for my machine design?

A: Yes, our engineering department provides 2D dimensional drawings and 3D CAD files (STEP/IGES) upon request.

Q: What output options are available for shaft-mounted applications?

A: We provide keyed hollow shafts, hollow shafts with shrink discs, torque arms, and output mounting flanges.
