Product 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.
