Design and function
The construction of our rotary atomiser is based on an aerostatic air bearing system that consists of radial and axial bearings fitted with micro jets. The radial bearing has a high load capacity of up to 96 N at the front end of the shaft, specially designed for use with robots (up to 3G). The bearing surfaces are made from special materials with very good failsafe running capability to be able to cope with shaft touch down. A pneumatic radial turbine drives the atomisers. The turbine blade geometry has been perfectly adapted to air inflow and exhaust speeds. The turbine air inlet
has been designed to ensure minimum pressure drop, from the connection right up to the blade. This means that the turbine blades are exposed to higher pressure, and this leads to considerably improved performance. A high-contrast axial encoder ring has been incorporated for speed sensing with an operating wavelengths of 880 nm or 650 nm.
