Kinematic analysis of tooth-lever differential transmission mechanisms

Abstract This paper refers to a problem of application of tooth-lever differential transmission mechanisms in roller technological machines with variable inter-axial distance of working shafts, which are widely used in civil and agricultural engineering. Shortcomings of tooth-lever differential transmission mechanisms, used in roller machines, were shown; they are expressed in discrepancy of kinematic characteristics of these mechanisms to technological requirements of different types of roller machines. An arrangement and a principle of operation of new tooth-lever differential transmission mechanisms, developed by the authors, are briefly considered here. The possibilities of application of offered transmission mechanisms in six principal schemes of roller machines are described. Formulas are drawn to determine kinematic parameters of one of new transmission mechanisms depending on geometric and kinematic parameters of two-roller modulus, processed material and transmission mechanisms itself.
