Gear Ring
Gear ring Features
High-precision tooth profile: CNC hobbing and grinding processes ensure smooth transmission and low noise.
High load-bearing capacity: Optimized tooth profile design effectively improves torque transmission capacity.
Diverse structures: Available with internal gear ring and external gear ring , spur gears, and helical gears.
High-quality materials: Utilize high-quality steels such as 42CrMo, 50Mn, and C45 for both strength and toughness.
Heat treatment enhancement: Tooth surfaces undergo induction hardening or full heat treatment for high hardness and long life.
