The Planetary Vibroexciter with Elliptic Inner Race

Abstract:

We present a method determining analysis of workflow of the planetary vibroexciter, allowing by constructing three-dimensional graphs obtained in MathCAD, combine several line graphs in one. Improves the availability the results of theoretical analysis, the influence of the main parameters of the vibroexciter on its dynamic characteristics. The use of a planetary vibroexciter with elliptic inner race gives substantial advantage in generated driving force against an analog vibroexciter, equipped with a round inner race with the same dimensions and initial parameters. Selecting the mode of setting the spider axis of a planetary vibroexciter in one of focal points of elliptic inner race leads to the increase of generated driving force, 2.2 times on abscissa axis and 2.4 times on ordinate axis, against the central position of the spider axis. This proves the effectiveness of the elliptic planetary vibroexciter use. 1.6 times increase of focal length results in directly proportional increase of driving force projection on ordinate axis, and 2.1 times increase of driving force projection on abscissa axis.
