Robots
Correctly painted

Modern, fully-automatic painting lines for the automotive, telecommunications or aircraft industry are highly specialised systems. The requirements for the painting technique and thus the robots which are used vary depending on the industry and the application. However, one factor is always the same: While emphasis is primarily placed on precise repetition and pinpoint placement of heavy loads for pick and place applications in the handling area, a painting robot may never deviate from the specified path. This must also take place at a specific speed with absolute precision. Even the slightest vibrations or fluctuations in velocity result in uneven colour application and a poor first-run rate. In a concrete application, the Nabtesco precision gear RV-100C with a hollow shaft diameter of 71 mm proved to be the ideal choice. The large hollow shaft could be used to route the supply lines.

In addition, the gear had all the impressive features which have made Nabtesco the world market leader:

• High transmission precision
• Vibration-free through two-stage reduction
• Backlash well below one angular minute
• Reliable and wear-resistant
• Double-end support and a symmetric gear design
• High rigidity
• Shock load resistance of up to five times the rated torque
• Integrated angular ball bearings
