Circular Flange high precision Reduction Planetary Gearbox

●  Introduction

The Shaft-Output Circular-Flange Planetary Gearbox is a planetary gear transmission system with a vertical 90-degree layout between the input and output shafts, both positioned on the same plane. The gearbox features a circular housing and a circular output flange. Power transmission and speed reduction are achieved through multi-stage gear meshing. Its compact and space-efficient design makes it ideal for general industrial applications with spatial constraints or requiring vertical input-output orientation.

Features

● Circular Housing and Flange Design

The gearbox housing and output flange adopt a circular structure. Screws are fastened vertically downward from the top, and additional flanges can be customized on the circular output end to meet specific customer requirements.


● 90-Degree Input-Output Configuration
The perpendicular shaft arrangement optimizes space utilization and redirects output torque.


● High-Efficiency Helical and Bevel Gears
Utilizes helical gears combined with an integrated bevel gear set, maintaining over 90% efficiency in multi-stage transmission.


● Ultra-High Precision and Low Backlash
Precision ground gears and a collet-style locking mechanism minimize backlash to ≤2 arcminutes (1/30 of a degree), meeting servo systems' stringent positioning accuracy demands.


● Exceptional Load Capacity
Multi-tooth meshing design evenly distributes loads. Carburized and quenched gears paired with needle roller bearings deliver output torque up to several thousand Nm and outstanding impact resistance.


● Noise Reduction and Vibration-Free Stability
Patented noise-reduction architecture and helical tooth rolling meshing technology reduce operational noise to minimal levels while ensuring smooth, vibration-free performance.


● Extended Durability and Zero Maintenance
Premium seals and lifetime lubrication technology ensure a gear service life exceeding 20,000 hours, even in extreme environments with high temperatures or heavy dust exposure.
