Abstract:Using an approach for building up a model of the spur involute gear dynamics previously implemented an improved model having new; more realistic; properties is constructed. First of all; an algorithm for contact tracking of cylindrical surfaces directed by involutes was rearranged. This algorithm is "simply" reduced to tracking of two involutes. As a result it turned out that common line normal to these both curves of contacting always coincides with line of action. This property makes it possible to obtain direct simple formulae for computations of contact. In the model under consideration a backlash in gearbox is also taken into account. This means that lost of contact between teeth is possible when gearwheels rotating. It is possible then to appear the contact patch for reversal. After that dynamical reasons can force the mesh process to return to the former mode of the forward stroke and so fourth. All such scenarios for modes switching are implemented in the model in a unified manner. To ensure the mesh reliability an overlapping in time of contacts between teeth pairs is used. This property is also implemented in the dynamical model under description. New contact of the next pair of teeth is formed and starts its motion along the line of action before the old contact will leave this line at point of teeth disengaging.
