Improvement of the Method for Restoring the Bearing Supports of Steel Crankshaft

Abstract

In the science of car repair, the problem of restoring worn-out crankshafts is very relevant. The engineering solutions proposed in the article will provide an increase in the technical and economic indicators of repair: an increase in the quality of coating by a gas-flame method with a finishing non-abrasive antifriction treatment. At the same time, the engineering solution consisting in the formation of one groove on each journal of the crankshaft, brazing of a copper wire, followed by flame spraying of a coating, sealed by a disk, and grinding of the journals (the bearing supports), provides a non-wear effect. So, thanks to the coil of copper wire, the resource of the crankshaft increases and the cost of repaired crankshafts are reduced in comparison with new ones.
