Abstract

1362976 Bearings LIDKOPINGS MEKANISKA VERKSTADS AB 8 Dec 1971 [14 Dec 1970] 56999/71 Heading F2A [Also in Division B3] A fluid bearing comprises two relatively movable elements and means for supplying fluid to the bearing which include a throttle formed by adjacent surfaces of the elements, the arrangement being such that variation in the separation of the opposed surfaces of the elements varies the flow of fluid to the surfaces. As described the bearing constitutes the slide of a machine tool. One bearing element 52 is secured to a reciprocating table 48, and is located in a groove 54 in the support 55, which forms the other bearing element. Pockets 4, 5, 6 are formed in the surface of one of the elements to which fluid is fed under pressure to form with the other element a fluid bearing. Each pocket has a corresponding pocket formed in the surface of the same element which is remote from the surface of the first pocket. The pairs of corresponding pockets are supplied from a common source 32. Fluid is led into a pair of restrictors comprising a central groove 13 in the surface of the element having the pockets surrounded by a land 26, which is surrounded by a groove around which is a further land. Fluid is fed into the central groove and passes over the land into the surrounding groove from which there is a passage which communicates with the pocket located in the face opposite that having the throttle.
