High-Performance Helical Gears for Precise and Quiet Power Transmission
Helical gears are the preferred choice for industrial applications requiring high speeds, heavy loads, and quiet operation. Unlike standard spur gears, the teeth of a helical gear are cut at an angle to the axis of rotation. This design allows for a more gradual and continuous tooth engagement, resulting in superior mechanical performance and durability.
Smooth and Silent Operation: The angled teeth engage progressively, distributing the load more evenly and eliminating the noise and vibration typically associated with straight-cut gears. This makes them ideal for high-speed gearboxes.
Increased Load-Carrying Capacity: Due to the inclined teeth, helical gears have a longer total contact line and a higher contact ratio. This allows them to transmit significantly more torque and withstand higher shock loads than spur gears of equivalent size.
Versatile Transmission Layouts: Our helical gears can be designed for both parallel shaft and crossed-axis (helical gears at 90 degrees) configurations, providing flexibility for complex mechanical designs.
Premium Materials & Precision Grinding: TINVO utilizes high-grade alloy steels such as 42CrMo, 20CrMnTi, and 18CrNiMo7-6. Every gear is precision-ground using advanced CNC equipment to achieve DIN 6 or AGMA 11+ accuracy grades.
Optimized Heat Treatment: To ensure maximum fatigue resistance and surface hardness (HRC 58-62), we provide expert-level Carburizing, Quenching, and Nitriding processes tailored to your specific application needs.
FAQ
Helical, herringbone, or single-helical — which should I specify?
Single-helical gears generate axial thrust and need a matching thrust-bearing arrangement. Herringbone (double helical) gears cancel that thrust within the gear and run quieter, at the cost of more complex manufacturing. Helical gears are the standard middle-ground choice — decide on load profile, axial-thrust tolerance, and lubrication regime.
What materials and surface hardness can TINVO deliver?
Alloy steels 42CrMo, 20CrMnTi, and 18CrNiMo7-6, with Carburizing, Quenching, or Nitriding for surface hardness HRC 58–62 and the core toughness your duty cycle needs.
What size and accuracy range can TINVO hold?
Up to maximum diameter 1M and maximum modulus 25, with tooth-surface accuracy to Level 5 and gear accuracy of DIN 6 / AGMA 11+ via precision CNC grinding. Higher precision classes are available on inquiry.
Can TINVO make helical gears for both parallel-shaft and 90° crossed-axis layouts?
Yes — we design helical gears for both parallel-shaft and crossed-axis (helical gears at 90 degrees) configurations, so tell us the shaft layout in the RFQ.
What should a helical-gear RFQ include?
Drawing (module, helix angle, tooth count, bore, keyway), material spec, heat-treatment tier, surface finish, and gearbox duty cycle. With these we reply with a candidate grade and finish-accuracy recommendation.

Customization
For industrial gearboxes, helical gear procurement typically happens as part of a power-transmission refit or new-mill expansion. Helical gears, herringbone gears, and single-helical gears are three distinct choices that mill engineers weigh against load profile, axial-thrust tolerance, and lubrication regime. TINVO supplies helical gears sized to drawing + module spec + heat-treatment tier; share your gearbox duty cycle and shaft-speed in the RFQ and we reply with a candidate grade and finish-accuracy recommendation.
