Balance of Reciprocating Masses
Model No. HV-EXP2586
Technical Description Using thebenchtop model, mass forces can be investigated on a reciprocating piston machine. The model has four pistons with plastic sleeves that do not require lubrication. The quadruple cranked crankshaft is driven by an electronically commutated DC motor via a toothed belt. The rotational speed is regulated and displayed digitally. Forces and moments are measured using strain gauges on the elastic boom of the model mounting bracket. All electrical functions are integrated into the control unit that also provides an analogue output for an oscilloscope. The crank offset for each cylinder can be continuously adjusted, as an aid marks are provided at 90°, 180° and 270°. The natural frequencies are defined such that resonant oscillations are easy to detect even without instrumentation..
