Abstract

1301109 Hydrostatic bearing pads CATERPILLAR TRACTOR CO 22 Dec 1969 [17 Jan 1969] 32396/72 Divided out of 1301108 Heading F2A [Also in division F1] An hydrostatic bearing pad 35, which is tiltably mounted in a pocket 36 having a source 38 of pressurized fluid, has a central recess 57 which is surrounded by two annular bearing lands 65, 63 having between them an annular recess 64, the outer bearing land being surrounded by a non-bearing land 60 in which is formed bleed notches (61, Fig. 6, not shown) there being passages 66 connecting the annular recess with the pressurized fluid source in the pocket and exhaust passages 67, 68 communicating with the central recess. There may be a recess 62 located between the outer bearing land and the non-bearing land.
