Frequently Asked Questions (FAQ)
-
Q: What is the advantage of using 42CrMo4 alloy for ring gears?
A: 42CrMo4 offers excellent strength, toughness, and wear resistance. It is commonly used in heavy-duty gears where high fatigue strength and resistance to shock loads are required. -
Q: How is the HRC 55-60 hardness achieved?
A: After precision casting, the gear undergoes controlled heat treatment (quenching and tempering) to achieve the specified surface hardness while maintaining core toughness. -
Q: What does DIN 6 precision grade mean in practice?
A: DIN 6 corresponds to a medium-high accuracy level per ISO 1328. It ensures tight tolerances on tooth profile, pitch, and runout, suitable for most industrial applications requiring smooth operation. -
Q: Can you supply ring gears with outer diameter larger than 1500 mm?
A: Yes, for larger sizes we can discuss customized solutions based on our production capabilities. Please contact us with your specific OD and module requirements. -
Q: Do you offer custom tooth profiles or modifications?
A: Absolutely. We can adjust the tooth profile, add tip relief, root relief, or other modifications according to your design. Minimum order quantities may apply. -
Q: What is the typical lead time for a standard ring gear?
A: Lead time depends on size and quantity. For standard modules and ODs, it typically ranges from 30 to 60 days. Custom orders may require longer. We will provide a precise schedule upon inquiry. -
Q: How do you ensure product quality?
A: We follow a strict quality control system: incoming material inspection, in-process casting inspection, post-heat treatment hardness testing, and final dimensional/gear inspection using CMM and gear testers. -
Q: What certifications do you have for this product?
A: Our factory is certified under ISO 9001, ISO 14000, OHSAS 18001, and other standards. The ring gear itself is manufactured to meet DIN 6, and we can provide a certificate of conformity upon request.
