This article introduced the mechanism design and the technical realization of experimental system of final drive. The system may realize to three types of final drive overall performance examinations, and evaluate the production performance according to the technique parameters beforehand. The integrated structure of test stand consists of ponents,namely:working mechanism,overturn mechanism,drive mechanism and supporting paper states the design and calculation of parts ponents for test stand in it introduce the process of ponents includes servo electromotor,speed reducer,torque and rotational speed sensor,linear guidway and ,it plish the design requirement and give out the technical specifications of the test stand.
