bevelhelical gearcoaxial

Product Introduction The Shaft Output Square 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 square housing and a square 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. - Square Housing and Flange Structure: The gearbox housing and output flange are designed in a square configuration. Screws are fastened upward from the bottom and secured to the mounting structure. - 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. - 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 requirements. - Exceptional Load Capacity: Multi-tooth meshing distributes loads evenly. Carburized and quenched gears paired with needle roller bearings enable output torque up to several thousand Nm and superior shock resistance. - Low Noise and Stable Operation: Patented noise-reduction technology and helical tooth rolling meshing design reduce operational noise while ensuring smooth, vibration-free performance. - Durability and Maintenance Free Design: High-grade seals and permanent lubrication technology ensure a gear lifespan exceeding 20,000 hours, even in harsh environments with high temperatures or dust exposure.
