Abstract

771,892. Face-plates and tables; lubricating slides. ESCHER WYSS AKT.-GES. July 7, 1954 [July 16, 1953], No. 19944/54. Class 83 (3). [Also in Group XXXIV] A slide-track 2, Fig. 1, e.g. for the face-plate 9, Fig. 2, of a vertical-lathe, has distributed therein a number of pressure-chambers 4 filled with lubricant and enclosed by guidetracks 2<SP>1</SP>, there being a number of lubricant feed-devices 6, each being separately connected to at least one of the chambers to maintain a film 14 between the guide-tracks and the plate. The plate may be supported additionally by a slide-track 1 having chambers 3 similarly fed with lubricant. The quantities of lubricant supplied to the feed-devices 6, while maintaining a substantially constant ratio between each other, are varied in dependence on the sliding-speed of the plate, whereby the thickness of film 14 remains constant. Pumps 8 supply the conduits 12 from a reservoir to which the lubricant is returned via channels 15. A single pump may supply all the chambers through distributing means, and the thickness of the film may be measured by a feeler which regulates the pump. A supply-system comprises a battery of pumps 36, Fig. 5, driven from a common shaft 37, having feed-devices 35, and drawing lubricant from reservoir 38. Shaft 37 is coupled to a shaft 37a connected by gears 48, 47 to a shaft 37b. A motor 45 is coupled to shaft 37b through a free-wheel 53 and the motor 40, which drives the face-plate 29, is coupled to said shaft through a free-wheel 54, whereby the pumps are driven by motor 45 when the face-plate is stationary or when motor 40 is rotating at a lower speed than motor 45. For rotation of motor 40 and the face-plate in the opposite direction, shaft 37 is driven by motor 40, when its speed exceeds that of motor 45, by gearing 50 and a freewheel 55.
