Current research on oscillating tooth gear drive mainly focuses on its structure and machining methods. In this paper, the reliability of roller oscillating tooth gear drive is studied by fault tree analysis. On the basis of the logical relations between events in the fault tree and Boolean algebraic operations, the formula is derived which calculates the probability value of the top event when the output shaft cannot rotate. An example is given to demonstrate the application of this method to a real roller oscillating tooth gear drive system.
