Mathematical represantation of the branch kinematics of a transmission with descreteflexible connection

The paper deals with the mathematical model development of kinematical behavior flexible transmission branch exemplified. A typical example discrete-flexible connection can be considered as movement drive elements chain. use chain gears a for wide range technological machines high requirements in order to ensure certain law motion executive bodies is task studying changes its kinetic characteristics during operation. It established that random deviations step from nominal are result manufacturing inaccuracy and wear gives an idea real interpretation kinematics taking into account uneven dimensions individual links. makes it possible present components given two groups: created by accumulated error section, movement. Calculations based on developed show when hinges sleeve-roller worn 2.5%, value coefficient non-uniformity increases threefold.
