摘要:
Thrust bearings are described comprising a substantially planar thrust accepting member (19) having at least one locating portion (20) substantially at a right angle thereto and which is adapted to co-operate with a recess (22) formed in the bearing housing. In a preferred embodiment there are two locating portions and the co-operating recesses in the bearing housing have re-entrant geometry to prevent accidental displacement of the thrust bearing during installation of the shaft.

摘要:
Flanged bearings are described which are amenable to reliable installation by robotics and which do not require such fine engineering manufacturing tolerances on the flanges as has hitherto been the case. A flanged bearing comprises a journal bearing element and at least one thrust bearing element constituting a flange and wherein the thrust bearing element is attached to the journal bearing element by flexible attachment means. Flanged bearings are described wherein flexible attachment portions (21) are formed from the steel backing material of a thrust bearing (20), slots (22) are also provided to enhance fexibility. The thrust bearing (20) is attached to a journal half bearing (23) by, for example, electron beam welds (24).
摘要:
A method and apparatus for forming plain bearings from a bearing strip consisting of a metal backing and a lining of bearing material. The apparatus comprises a series of tube forming rolling mills (114,115,116 and 117) arranged to roll the strip (111) to a part cylindrical form; a closed pass forming die (131) having an internal mandrel (132) arranged to form the rolled strip (127) to a final tube configuration (129); a drawing mechanism arranged to draw the strip/tube through the rolling mills and die; and a severing mechanism (133) arranged to cut the formed tube (129) in to lengths (134).
