This invention is a tilting thrust pad bearing in which bearing pads 11 are supported on individual pillars 19 which themselves bear on supporting bars 23, carried by rockers 24. The supporting bars and rockers are identical components and can be used in different numbers for large diameter and small diameter bearings, while yet where they support one another, there can be one point or two point connection by virtue of an arcuate ridge 41 at one end of each component, and a slightly domed surface 43 at the other end of each component. |

DETAILED DESCRIPTION I claim: 1.
A thrust bearing comprising a ring of thrust pads, supporting bars, each supporting one of said thrust pads, and a ring of rockers, each adjacent pair of said rockers having ends overlapping and supporting respective ends of one of said supporting bars, all of said rockers and said supporting bars being identical components, the improvement comprising that said overlapping parts of said ends at one side of said components are each formed with an arcuate ridge, in such a way that where respective ends of a rocker and supporting bar overlap, there are two abutment regions where said ridges cross one another, while at the other side of said rocker and said supporting bar, said components are shaped such that there is a single abutment region.
2.
The bearing of claim 1 in which said overlapping ends of said identical components are of convex rounded shape when seen in the direction of the bearing axis.
3.
The bearing of claim 2 in which said rockers are shaped and arranged to be capable of rocking in relation to a bearing housing about a generally radial line.
4.
The bearing of claim 3 in which said supporting bars are shaped and arranged to rock in relation to their thrust pads about a generally radial line.
5.
The bearing of claim 4 in which said identical components are each formed with a ridge defining the radial rocking line.
6.
The bearing of claim 5 in which said thrust pads are shaped and arranged to be capable of rocking about a generally radial line in relation to their supporting bars.
7.
The bearing of claim 6 further comprising a pillar positioned between each thrust pad and its supporting bar with means permitting said thrust pad to rock in relation to its pillar about a first radial line, and additional means permitting said supporting bar to rock in relation to said pillar about a second radial line axially spaced from said first radial line.
8.
The bearing of claim 7 further comprising a lubricant delivery post, positioned between adjacent pairs of thrust pads, and acting to separate said thrust pads circumferentially, and also acting to lubricate the region between said thrust pads
