Research of the Method of Electrohydraulic Distribution when Restoring Parts of Crank – Connecting Rod Mechanism
Abstract: The article describes a method for restoring the piston pins of internal combustion engines through the use of the method of electro-hydraulic distribution. The degree of influence of the electrical parameters of this process on the amount of deformation of the piston pins is determined, depending on the material used for the product and the volume of hardening chemical-thermal treatment. To implement the method under consideration, it is necessary to have accurate information about the magnitude and nature of the distribution of wear on the piston pins and their working surfaces. The corresponding studies were carried out on the piston pins of the repair stock of diesel and spark engines of trucks. In relation to the well-known methods of recovery, for example, heat treatment and distribution with a rigid punch, the process considered in the article is characterized by lower residual stresses, higher quality and efficiency.
Keywords: restoration, piston pin, electro-hydraulic expansion, wear, repair size, plastic deformation of metal, electromagnetic energy, energy of explosives.
