Aerostatic bearing spindle for use in e.g. electrostatic varnishing machine, has housing surrounding and supporting bush, and flexible supporting device arranged between bush and housing, where supporting device is electrically conductive

摘要

The spindle (1) has a bearing bush (20) arranged in such a manner that it surrounds an outer circumference surface of a rotating shaft (10). A housing (30) surrounds and supports the bearing bush. A flexible supporting device (40) e.g. mesh unit, is arranged between the bearing bush and the housing, where the flexible supporting device is electrically conductive. The flexible supporting device has an O-ring (41) and a conductive material (71) with an electrical conductivity, which is mounted in a surface of the O-ring.
