A process for the manufacture of half bearings with flanges rigidly connected thereto, made of a steel plate with an antifriction layer, in which the plain (i.e. not yet flanged) half bearing and a pair of flanges are produced and worked separately, and subsequently the two flanges are fixed, in the correct position, onto the half bearing by a welding operation carried out by projection or by condenser discharge. The preparation and working of the thus separate components results in being very economical owing both to the reduction of the operational costs and to a considerable reduction of the cost of the necessary equipment, and the production times are remarkably reduced. The welding step requires very short times and, by the suitable choice of the process used for the welding operation, no deterioration of the antifriction layer applied to the support steel plate occurs, nor any deformation of the plate itself, so that no further working on the finished piece is required. This latter has a sturdiness adapted to the use of mechanized assembly means. |
