SYMPTOMS AND A SENSOR FOR PERMANENT DIAGNOSIS OF MACHINES WITH A PISTON-CRANK MECHANISM

Piotr Bielawski

Abstract

The piston-crank mechanism and influence of its technical condition on safety is presented. Diagnostic signals, which may be useful in diagnosing of mechanism elements are enumerated. The choice of taking the crankshaft free end as a point of diagnostic signals permanent measurement is justified. The classification of machine units and their loads are done. There is pointed out the possibility to increase the diagnosis accuracy made by measurements on the free end of crankshaft. Attention is drown to the necessity of considering dynamical characteristics of machine unit in process of inference about the technical condition of the piston-crank mechanism elements.
