Core Product Advantages
Compact Right-Angle Layout: Saves linear installation space by orienting the motor 90° relative to the driven shaft.
Integrated Plug-and-Play Drive: Factory-assembled motor and gearbox eliminate manual alignment and reduce installation labor.
Reverse Self-Locking Function: High-ratio units (1:30 and above) offer static self-locking capability, providing an extra mechanical safety factor in inclined conveyors and hoist machinery.
Low Noise & Vibration: Precision tooth profile grinding ensures smooth operation (< 65 dB noise level), suitable for quiet indoor environments.
Flexible Mounting Configuration: Supports all-angle installation (B3, B5, B14, torque arm) with solid or hollow shaft options.
Industry Applications
Belt & Modular Conveyors: Controlled speed and right-angle footprint for logistics, packaging, and food processing lines.
Roller Conveyor Drives: Drive shaft interface for warehouse distribution and pallet handling systems.
Packaging Machinery: Precise indexing and power transmission in wrapping, cartoning, and labeling machines.
Agitators & Mixers: Reliable torque multiplication for liquid mixing and chemical processing tanks.
Automation & Hoisting Equipment: Compact power units for door operators, scissor lifts, and rotary index tables.
Structural Construction
The G Series features an integrated drive layout housing high-grade mechanical components:
AC Motor: High-efficiency copper-wound motor with optimized thermal dissipation fins.
Worm Shaft: Carburized and ground 20CrMnTi alloy steel shaft for high durability.
Worm Gear: Wear-resistant ZCuSn10Pb1 tin bronze wheel for smooth meshing and low friction.
Bearings & Seals: High-precision bearings paired with NBR/FKM oil seals to eliminate oil leakage.
Housing: Lightweight, high-tensile aluminum alloy or rigid cast iron structure providing heat dissipation and structural rigidity.
Installation & Operating Guidelines
Ensure a rigid, flat mounting surface to avoid housing stress or misalignment.
Maintain exact alignment with driven shafts; avoid excessive hammering on output shafts to protect internal bearings.
Verify supply voltage matches motor nameplate specs and check fan rotation direction.
Run under no-load conditions first to monitor operating sound, vibration, and temperature before applying full load.
Customizable Options
Mechanical: Special shaft extension lengths, custom keyways, spline shafts, custom flange sizes, stainless steel shafts.
Electrical: Special voltages (110V – 690V), dual-frequency (50/60Hz), DC electromagnetic brakes, external cooling fans (forced ventilation), incremental encoders.
Protective Coatings: Epoxy washdown coatings, anti-corrosion marine paints, food-grade synthetic lubricants.
Quality Control
Our manufacturing facilities operate under ISO9001 quality management standards to ensure international interchangeability and long service life.
CNC Gear Processing: Worm shafts are induction-hardened and thread-ground. Worm gears are hobbed using CNC equipment to achieve ISO/DIN Class 6-7 gear precision.
Precision Housing Machining: CNC machining centers process housings in a single setup to maintain concentricity and precise shaft alignment.
100% Factory Inspection: Every assembled unit undergoes a running test verifying noise, vibration, thermal rise, sealing integrity, and electrical performance before shipment.
Technical Documentation, Inspection & Export Packaging
Document Package Supplied: Specification data sheets, 2D DWG / 3D STEP drawings, factory test report, motor nameplate certificate, and operating/maintenance manual.
Export Packaging: Units are treated with anti-rust oil, wrapped in protective moisture-barrier film, and packed in heavy-duty export-grade wooden cases compliant with ISPM 15 heat-treatment standards.
Frequently Asked Questions
Q: What information do I need to provide for a complete model selection?
A: Provide motor power (kW), required output speed (rpm) or torque (N·m), voltage/frequency, output shaft type/size, mounting orientation, and application environment.
Q: Can your G Series gearboxes directly replace my current gearbox brand?
A: Yes. Provided the mounting dimensions, shaft diameter, and performance ratings match, our units are standard drop-in replacements. Share your existing unit's nameplate photo or drawing for instant verification.
Q: Do high reduction ratios provide self-locking capability?
A: Yes. Ratios of 1:30 and higher generally offer static self-locking, preventing the load from back-driving the motor. For dynamic self-locking or critical safety hoisting, an external motor brake is recommended.
Q: Can I obtain 3D CAD models before placing an order?
A: Yes. We provide free 2D (DWG/DXF) and 3D (STEP/IGES) CAD files to design engineers for integration checking before order confirmation.
