Diagnostics of the main, connecting rod bearings in the crank mechanism
Keywords:
diagnostics, car, main and connecting rod bearings, crank mechanism, the method of diagnosis, the pressure parameters, diagnostic parameters, methods and tools, the technical conditionAbstract
Methods and means of diagnosing main and connecting rod bearing crank drive trucks and tractors. Examined the change in pressure and fluid flow through the engine crankshaft bearings. Аpplied a method of diagnosing the state of sliding bearings indiscriminately еngine. Еstablished diagnostic device. We have established the relationship between the eccentric bearing profile and the amount of pressure with no load and under load. We confirmed that the bandwidth through the main and connecting rod bearing is characterized by dynamic and static qualities throughputs of these nodes.When conducting experimental studies on the linkage of technical condition of main bearings with the magnitude of the pressure signal was detected most sensitive mode - idle speed for the engine “ZMZ-4062”. Presents experimental studies.
