Product Description
Helical-tooth planetary gear reducer
This planetary gear reducer features high-strength alloy gears and an integrated precision housing design, delivering core advantages including high-precision transmission (accuracy up to 1-5 arc minutes), high torque output, and low-noise operation. It is compatible with various servo motors and stepper motors. Its compact structure and flexible installation effectively enhance equipment transmission efficiency and operational stability, making it a core transmission component in industrial automation.
| High-precision helical gear structure High load capacity, high transmission smoothness High transmission accuracy, low noise Spur gears: The line of contact is straight, with typically low contact ratios (generally 1.0–1.5) Helical Gears: The line of contact is helical. The meshing coefficient is divided into the tangential meshing coefficient and the axial meshing coefficient, with the total meshing coefficient being significantly higher (reaching 2.0–3.0 or higher). Under equivalent module conditions, the load capacity of helical gears is twice that of straight-cut gears. |
