Frequently Asked Questions
Get answers to common questions about our gear shaft manufacturing services and capabilities.
What is the difference between hobbing and gear shaping?
Hobbing is a continuous generating process where both the hob and workpiece rotate simultaneously, making it highly efficient for external gears. Gear shaping uses a reciprocating cutting motion and can produce both internal and external gears, making it more versatile for complex geometries but typically slower than hobbing.
What accuracy grades can you achieve for gear teeth?
We can achieve DIN quality grades 4 through 8, depending on the manufacturing process and requirements. Precision ground gears can reach DIN 4 quality, while hobbed gears typically achieve DIN 6-8 quality. The specific grade depends on module, diameter, face width, and application requirements.
What heat treatment options are available for gear shafts?
We offer comprehensive heat treatment services including carburizing with case depths from 0.5mm to 3.0mm, induction hardening for selective hardening, through hardening (quench and temper), nitriding for improved wear resistance, and stress relieving. The choice depends on material, application loads, and performance requirements.
What is your typical lead time for custom gear shafts?
Lead times vary based on complexity, quantity, and material requirements. Prototype parts typically require 2-4 weeks, while production quantities range from 4-12 weeks. Rush orders can often be accommodated with our expedited processing. We provide detailed scheduling during the quotation process.
Can you manufacture gear shafts with internal splines or keyways?
Yes, we have complete capabilities for internal features including splines (involute and straight-sided), keyways, internal gears, and complex bore geometries. Our broaching and EDM capabilities allow us to produce intricate internal profiles with tight tolerances.
What materials do you recommend for high-load applications?
For high-load applications, we typically recommend case-hardening steels such as 8620, 9310, or 16MnCr5 with carburizing treatment. These materials provide a hard, wear-resistant surface while maintaining a tough core for impact resistance. Material selection depends on load types, operating environment, and fatigue requirements.
Do you provide design assistance for gear shaft optimization?
Yes, our engineering team provides comprehensive design support including gear geometry optimization, material selection guidance, manufacturing process consultation, and cost reduction analysis. We use advanced simulation software to optimize designs for strength, noise, and manufacturing efficiency.
What quality certifications and inspection reports do you provide?
We provide complete certification packages including material certificates, dimensional inspection reports, gear analysis data, surface finish measurements, and hardness testing results. Our ISO 9001:2015 and AS9100D certifications ensure comprehensive documentation and traceability for all parts.
