Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for a 15m diameter girth gear?
A: Lead time depends on the specific requirements and current production schedule. Typically, it ranges from 4 to 6 months. Please contact us for an accurate estimate based on your order. -
Q: Can the gear be manufactured with different tooth profiles (e.g., involute, cycloidal)?
A: Yes, we can machine standard involute profiles as well as custom profiles per your design. The module 30 specification is standard, but we can adjust the tooth geometry as needed. -
Q: What is the maximum hardness achievable after heat treatment?
A: Through quenching and tempering, we can achieve surface hardness in the range of 280–320 HB. For higher hardness (e.g., 350–400 HB), additional surface hardening processes like nitriding are available upon request. -
Q: Do you provide installation and after-sales support?
A: We offer technical documentation, on-site installation guidance (if required), and a standard warranty period. Our team can assist with troubleshooting and spare parts supply. -
Q: Is the gear suitable for wet grinding environments (e.g., slurry)?
A: Yes, the forged alloy steel with proper sealing and corrosion protection can withstand wet conditions. We recommend discussing your specific environment for additional coating or material options. -
Q: What certifications do your products hold?
A: Our factory is certified under ISO9001, ISO14000, OHSAS18001, SA8000, and many others. We can provide a certificate of conformity with each shipment. -
Q: How do you ensure the gear's balance and smooth operation?
A: Every gear undergoes dynamic balancing after machining. We also perform run-out and tooth contact pattern inspections to guarantee smooth meshing and low vibration. -
Q: Can you supply a complete drive system including pinion and bearings?
A: Yes, we can supply the matching pinion gear, shaft, and bearings as a package. Please inquire for a complete system quotation.
