Spur gear wheel

straight-toothedinternal-toothedcarbon steel

Overview

Hansheng Automation's carbon steel gears are precision transmission components designed for demanding, high-performance applications. Manufactured using Power Skiving (Kashifuji KPS30) and controlled heat-treatment processes, these gears deliver accurate profiles and stable running for automation, robotics, medical devices and industrial equipment.

Key features and capabilities

• High-precision manufacturing: ISO/DIN Level 5 accuracy (equivalent to AGMA 12/13) for low noise, minimal runout and high-speed stability.
• Advanced cutting: Power Skiving (Kashifuji KPS30) enables internal and external gear machining, hard skiving after heat treatment, and cutting near shoulders or interference features.
• Material options: medium carbon steels (AISI 1045 / S45C / C45), carburizing alloys (20CrMnTi, AISI 8620) and high-strength alloys (42CrMo / AISI 4140) for high-torque applications.
• Heat treatment & surface options: carburizing & quenching, nitriding, induction hardening, tempering; finishes include precision grinding, black oxide, zinc plating and phosphate coating.
• Durability: tooth flank hardening and finishing for wear resistance and improved shock-load performance.

Production & process highlights

• Complete workflow: DFM review, precision blank preparation (CNC lathes & milling), gear cutting (Kashifuji KPS30), heat treatment, finishing (grinding or hard-skiving) and final inspection.
• Available technologies: Gear Skiving (Kashifuji KPS30), hobbing, precision grinding; capability to hard-skive after heat treatment to correct distortion.
• Customization: full support for custom designs of spur, helical and internal ring gears from prototype to mass production.
