Basic Principles for the Construction of Dynamic Models of the Planetary Gears Used in Drilling Rigs

详细

Questions regarding the construction of discrete dynamical models are considered, using as an example 2K-N planetary gears with different types of stop couplings and their analytic dynamic models are presented. The principal assumption adopted in the creation of dynamic models of the types of simple planetary gears used in drilling rigs involves the supposition that the motion of the planetary wheel may be decomposed into two types of rotation, first, about the natural axis and, second, about the common axis of the reducing gear (carrier). An evaluation of the assumption is given.
