Abstract

1330484 Bearings SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 7 Oct 1970 [9 Oct 1969] 47734/70 Heading F2A A rotatable member, e.g. the drum of a rotary stone crusher, is supported by a plurality of individual hydrostatic bearing units acting on a bearing ring of the member and mounted so as to be self aligning with respect to the envelope of the bearing ring, the fluid supply system being such that constant bearing clearance is maintained. The member is supported by two types of bearing unit 14, 15 arranged symmetrically about the centre of the member as shown in Fig. 3. Both types of unit have a base 16 having at its upper end a cylinder in which is located a piston 17 integral with the part which engages the bearing ring 13. The piston has a spherical surface to allow angular movement relative to the cylinder thereby providing for self alignment with the bearing ring. The piston is allowed to pivot on a ball 25 seated in the base 16. Bearing fluid is supplied to the units by independently driven pumps 31, 32, 33, 34 via ducts 19, and thence to the bearing surface via ducts 22. In the outer bearing units 15 fluid is also supplied via duct 30 to a cylinder 26 where it acts on a piston 27a attached to a rod 28. When fluid is supplied the rod is raised, lifting the ball 25 from its seat, thereby raising the upper bearing part. The cylinder 26 in unit 15 communicates with a similar cylinder in unit 14 via duct 29. The piston 27 in unit 14 has a smaller diameter than that of piston 27 and therefore the rod 28 is raised to a lesser degree than the rod in unit 15. Piston 27 is, however, permitted a larger stroke than piston 27a. If the rotatable member is subjected to uneven load, the clearance between the bearing ring and one of the outer units is decreased, thereby impeding outflow from the bearing pad 21. The consequent increase in the supply duct is communicated to the cylinder 26 in unit 14 and causes further raising of the rod 28, thereby lifting the bearing pad of unit 14 to counteract the increase in load on the one side of the bearing.
