Custom machining alloy external and internal spur gear OEM

Categories: ,
We are a professional foreign trade precision manufacturing factory specializing in custom spur gear machining, non-standard external spur gear and internal spur gear OEM/ODM production. Equipped with advanced CNC gear hobbing, gear shaping and precision grinding equipment, together with standardized heat treatment and full quality inspection systems, we deliver high-precision, high-strength, low-backlash spur gears for general industrial transmission, automation equipment and gearbox systems. With stable dimensional accuracy, excellent meshing performance and reliable batch consistency, we serve global machinery manufacturers, automation enterprises and overseas trading companies, providing one-stop spur gear customization, manufacturing and export services.

1. Customizable Spur Gear Types & Core Parameters

We provide full-spec custom processing of standard and non-standard spur gears, covering external spur gears and internal spur gears in various sizes and structures. All technical parameters can be fully customized according to customer 2D drawings, 3D models or sample standards to adapt to different speed, torque and assembly structure requirements.
  • Custom Parameter Range: Module 0.5–12, customizable tooth number, pitch diameter, addendum circle, dedendum circle, pressure angle, shaft hole diameter, keyway size and tooth width. Supports micro small-module precision gears and large-module heavy-duty spur gears for industrial equipment.
  • Main Product Range: External spur gear, internal spur gear, spur gear shaft, integrated gear shaft, plate-type spur gear, thickened heavy-load spur gear, hardened precision spur gear pair and non-standard custom gear assemblies.
  • Precision Grade: Stable ISO 6–9 precision standard, low tooth runout, minimal transmission backlash and high meshing uniformity, fully meeting high-precision and high-stability transmission requirements for industrial machinery and automated equipment.

2. Industrial-Grade Material Options

To adapt to diverse overseas industrial working conditions, load levels and environmental requirements, we provide multiple professional material solutions for custom spur gears, balancing strength, wear resistance and cost performance:
  • 45# Carbon Steel: Good toughness, easy processing and cost-effective, suitable for medium-speed and medium-load conventional industrial transmission equipment.
  • 40Cr / 42CrMo Alloy Steel: High hardness, strong torsion resistance and excellent fatigue resistance. After quenching and tempering treatment, it is widely used for heavy-load, long-term continuous operation spur gears.
  • 20CrMnTi Carburizing Steel: Hard tooth surface and tough core structure, outstanding wear resistance and impact resistance, ideal for frequent start-stop and high-load impact working scenarios.
  • Copper Alloy: Self-lubricating, low noise and anti-wear, suitable for high-end precision equipment requiring stable and silent transmission.
  • Nylon / POM Engineering Plastic: Lightweight, corrosion-resistant and low-noise, widely used for low-load, anti-corrosion and food-grade environmental protection transmission equipment.
Available surface treatments: blackening, galvanization, high-frequency quenching, carburizing hardening, precision tooth grinding, anodizing and anti-rust coating. Effectively improve surface hardness, abrasion resistance and corrosion resistance, adapting to complex overseas working environments such as high temperature, humidity and dust.

3. Professional Machining Technology & Quality Control

Spur gears feature straight-tooth parallel meshing, requiring high tooth profile accuracy and tooth spacing consistency. We adopt standardized gear hobbing, gear shaping and finish grinding processes for both external and internal spur gears to ensure stable transmission, high efficiency and low backlash operation.
  • High-Precision Tooth Profile Control: Strict tooth profile and tooth spacing calibration ensures uniform meshing contact, stable linear transmission and high power transmission efficiency.
  • Professional Internal Gear Machining: Adopt dedicated gear shaping process for internal spur gears to avoid tooth deformation, ensuring accurate inner ring tooth profile and smooth assembly matching with planetary gear sets.
  • Stable & Efficient Transmission: Optimized tooth surface finishing reduces meshing friction and impact vibration, realizing high-efficiency, stable and low-noise operation during long-term continuous running.
  • Strict Batch Interchangeability: Unified processing standards and full dimension inspection ensure consistent precision of batch products, convenient for customer assembly, replacement and equipment maintenance.

4. Industrial Application Scenarios

Custom external and internal spur gears are the most widely used basic transmission components, suitable for various industrial straight-line parallel transmission systems:
  • Industrial Gearboxes & Reducers: Matching spur gear pairs and internal gears for planetary reducers, gear motors and industrial transmission boxes.
  • Automation Machinery: Transmission gears for automated assembly lines, packaging machinery, textile machinery and logistics conveying equipment.
  • General Mechanical Equipment: Driving gears for machine tools, printing machinery, woodworking machinery and food processing equipment.
  • Heavy-Duty Industrial Machinery: High-strength wear-resistant spur gears for mining machinery, construction machinery and agricultural equipment.
  • Precision Intelligent Equipment: Low-backlash precision spur gears for testing instruments and small precision transmission devices.

5. Professional Foreign Trade Export Service
