Abstract

994,530. Bearings. PHILIPS' GLOEILAMPENFABRIEKEN. N. V. March 25, 1963 [March 28, 1962], No. 11688/63. Heading F2A. [Also in Division B3] In a fluid bearing, one of the parts is provided with at least one magnet and the other part is provided with at least one magnet or is made at least partly of ferromagnetic material, so that the co-operating faces of the two parts are drawn towards each other. In an embodiment as shown in Figs. 3 and 4, the fluid bearing is also a rectilinear bearing and comprises a fixed member 31 and a movable member 33. The former being of ferro-magnetic material and the latter being of non-magnetic material, having magnets 35, 37 inserted therein, and having ducts therein which are connected to a pressurized-air supply (not shown). The pressurized-air is passed to the clearances between guiding faces 47, 43 and 45, 41 of the fixed and moving members so as to form an air-cushion therebetween. The magnets may be positioned so as to balance thrust caused by a machining operation, for example, are preferably inserted in the smaller of the relatively movable members; and may be electro-magnets. The co-operating faces of the members may be curved as shown in Fig. 5. The clearance between the members may be maintained constant by using a known feeler device with variable capacitor so as to vary the energizing current of the electromagnets.
