Product Features
Wear-resistant torque reinforcement
Laser-hardened involute splines (HRC55+) improve torque transmission efficiency, while wear-resistant keyways reduce inner shaft wear (suitable for pinion gears in heavy-duty gearboxes).
The double-top-line locking structure at the shaft end (200% design torque without loss of locking) eliminates the risk of slippage in open transmission scenarios such as construction machinery.
Precision Heat Treatment and Quality Inspection
Vacuum carburizing layer depth ±0.005mm (HRC60-62), -196°C deep cryogenic treatment improves wear resistance by 30% (suitable for high-speed requirements of robot joints).
Zeiss coordinate measuring machine full inspection (tooth profile error ≤4μm), achieving ISO 5-grade precision (meeting precision requirements for aviation instruments and other applications).
Full-parameter customization capability
Module range: 0.1–5.0 mm , Gear tip diameter supports 3mm-300mm, tooth count: 8–25 (including designs with fewer than 14 teeth), pressure angle: 20°/25° selectable.
Special material customization: 17-4PH stainless steel (corrosion-resistant), 7075 aluminum alloy (lightweight model car small gears).

FAQ
Q: How to customize non-standard module pinion gears?
A: Customization is available for the full module range from 0.1 to 5.0 mm. For example, 0.2 mm micro-module gears use precision hobbing technology combined with POM material to reduce processing costs. Please provide the module, tooth count, or operational requirements (e.g., torque of 100 N·m), and we will provide material and process solutions.
Q: How to avoid root cutting when the number of teeth on a small gear is less than 17?
A: We use a positive displacement design (e.g., displacement coefficient x=0.176 when Z=14), thickening the tooth root by 25%, and enhance tooth surface hardness to HRC62 through vacuum carburizing to ensure bending strength ≥900 MPa.
Q: How to select pinion parameters for high-speed applications?
A: We recommend 20–40 teeth (to reduce impact) + 1–1.5 mm module + β=15° helical tooth design, paired with G1.0 dynamic balancing (residual imbalance ≤0.5 g·mm/kg), which can reduce noise levels in machine tool spindle pinions to below 65 dB.
