Testing the rigidity of the universal flanged centre shifter while sanding crankshaft necks of agricultural tractors

The repair and mechanical workshop, where the current repair of equipment is carried out, is an integral part of the technical service of an agricultural enterprise. There are specialized repair companies involved in restoration of basic machine parts. The development and implementation of advanced technologies for restoring parts will improve the quality of repairs and extend the service life of agricultural machinery. A universal flanged centre shifter is a device designed to shift a part relative to its axis of rotation before machining, for example, before sanding crankshaft necks. One of the factors affecting the accuracy of mechanical cutting and subject to research in this paper is the rigidity of the technological system “machine – tool – part”. The rigidity of the technological system is understood as the ability to provide resistance to deformation forces.
