Title: Aerostatic or hydrostatic bearing
IPC: F16C32/06
Filed: 1970-08-26
Abstract: 1327776 Externally pressurized bearing NETHERLANDS APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY TRADE & COMMERCE 26 Aug 1970 [29 Aug 1969] 41058/70 Heading F2A An externally pressurized bearing comprises a bore 1 and a shaft 2 rotatably mounted therein, means for feeding fluid lubricant between the surfaces of the bore and shaft and a ring whose axis is parallel with the axis of the shaft and which is radially movable under the influence of lubricant flowing past it to control the distribution of lubricant between the surfaces of the bore and shaft. In one embodiment (Fig. 1) the ring 5 is mounted for radial movement at one end of a journal portion of a shaft. Pressurized lubricant is introduced into the bore at the end of the journal remote from the ring and flows between the journal and bore and then between the ring and bore. On radial displacement of the journal in the bore, the flow of lubricant over the journal ceases to be uniform, thereby decreasing the resistance to flow at one radial location. As a result the pressure gradient and the pressure on the ring changes causing it to take up an eccentric position in the bore where it offers a greater resistance to the lubricant at the radial location where the journal offers a lower resistance. In an alternative embodiment (Fig. 5, not shown), the shaft is located in a bore in a sleeve in which there are ports for supplying lubricant, the ring being arranged around the outside of the sleeve.
