In power transmission design, when you need to connect two non-parallel, non-intersecting shafts to achieve smooth, high-torque transfer, Crossed Helical Gears (Skew Gears) are the irreplaceable core component. Utilizing unique point-contact mesh geometry and high-precision manufacturing, our custom crossed helical gears deliver efficient, quiet, and compact drive solutions for automation equipment, robotics, and precision instruments.
Key Advantages & Performance Highlights
-
Flexible Spatial Configuration: Specifically engineered for non-intersecting shaft angles (typically 90 degree). A single gear pair directly transfers power across staggered shafts without complex multi-gear combinations, saving valuable spatial real estate.
-
Smooth & Ultra-Quiet Operation: Involute helical teeth ensure a gradual, progressive mesh. This significantly dampens operational noise and vibration, making them ideal for noise-sensitive environments.
-
High Precision & Wear Resistance: Machined via high-precision CNC gear hobbing and tooth profile grinding, paired with carburizing or nitriding surface treatments to mitigate point-contact wear and extend service life.
-
Versatile Material Pairing: Supports material combinations like “Steel on Steel,” “Steel on Bronze,” or “Steel on Engineering Plastics (e.g., PEEK/POM)” to reduce friction coefficients while achieving self-lubrication and weight reduction.
