Design Method of the Advanced Actuator

The advanced actuator is a kind of swaying mechanism being an ingenious combination of high pressure oil cylinder and ball helical transmission, has lots of advantages, such as the torque produced by its unit weight is the greatest, dimension is little, weight is light, mechanical efficiency is efficient, service life is long, reliability is high, etc, it may be widely applied to varied occasions which need swaying mechanisms with low rotational speed and great torque.This paper firstly introduces mechanism composition and working principle of the advanced actuator.Then gives ascertaining methods on such key parameters as helical lift angle,pitch diameter,ball diameter,oil pressure and internal diameter of oil cylinder, etc.Next summarizes the analyzing and designing methods of the advanced actuator in a systematic way.Lastly points out three problems requiring thorough study.Successful development of the advanced actuator is an example of fulfilling major project by adopting modern method of design.Its systematic methods on analyzing and designing make further advances on the theories of ball helical transmission.
