Dynamics of toothed wheels with pin connections

Abstract

At gyration of a toothed wheel pinned with the shaft and at change of an angular standing of pins rigid parameters of an elastic-system can vary. It can cause both the forced parametric excitation, and parametric instability and resonances of an elastic-system, which includes such joints. Requirements and the reasons of such oscillations are investigated. Conclusion is done, that only single-pin connection can induce a dynamical instability of elastic-systems including systems with toothed wheels.
