Crossed Helical Gears

Crossed helical gears, also called screw gears, are helical gears that mesh with non-parallel, non-intersecting shafts. They transmit power between shafts at an angle, typically 25° to 90°, and are used where layout space is limited and smooth, quiet transmission is required.

Raydafon produces crossed helical gears with module 0.8-4 mm and shaft angle adjustable from 25° to 90°. Ground tooth surface and transmission efficiency over 90% are standard on the production range. Custom module, tooth number and shaft angle are supported against customer drawings.

Material options include high-strength alloy steel, stainless steel, aluminum bronze, nylon and wear-resistant engineering plastics. Material selection depends on load, speed, corrosion resistance and noise requirements.

Crossed helical gears are used in compact automation equipment, laptop cooling fans, dental chair adjustment systems, automotive engine auxiliary drives such as water pumps and generators, and smart curtain transmission devices. Any application requiring non-parallel shaft transmission in limited space can use crossed helical gears.
