Abstract： To address the problems of the allocation reliability of lower-level units being greater than that of the upper-level unit in the multi-layer structure reliability allocation of mechanical systems，a novel reliability allocation method was proposed. Firstly，the mechanical systems were divided into a system-function-motion-action（SFMA） hierarchy structure. Then，according to the hierarchy structure consisting of distribution and transmisson models，the reliability alocation techniques were proposed by combining the minimum cost method and reliability function，and the reliability allocation models of the mechanical systems，function units，motion units，and sub-motion units were established from top to bottom.Finally，taking the gear grinding machine as an example，the feasibility and effectiveness of the proposed method were verified.

Key words： mechanical system; meta-action unit； distribution model; transmission model; reliability allocation
