This article explains the operation, advantages, design aspects, and application areas of these advanced gear solutions for robotic arms.to optimally equip robotic arms with integrated multi-stage planetary gears.
Integrated multi-stage planetary gears are an established technology for more precise and powerful robotic arms in reduced space. These compact gears for robots combine multiple gear stages in one housing, leading to a high power density. For example, such integrated gear solutions for robotic arms allow welding robots from manufacturers like KUKA to perform movements with a repeatability of less than 0.05 millimeters. The integration results in a significant performance increase.
The significance of these robot gears lies in their ability to transmit high torques while enabling precise movements. A planetary gear distributes the load across multiple planetary wheels, increasing load capacity and minimizing backlash. This is particularly relevant for robot arms with dynamic load changes and high accelerations, where an integrated multi-stage planetary gear plays to its strengths. Delta robots in the packaging industry handle over 200 parts per minute with Neugart NDF gears. The design of the planetary gear for the robotic arm affects cycle time and productivity. The selection of optimal gears with servo motors is crucial for specific requirements.
Core components of an integrated multi-stage planetary gear for robotic arms include a central sun gear, multiple planetary gears, a planet carrier, and a ring gear. In multi-stage planetary gears several of these arrangements are connected axially in series to achieve higher overall gear ratios.
