Abstract

The invention relates to an integrated electromechanical servo mechanism. A redundant system is jointly composed of an EHA, an EMA and a clutch, wherein the EHA and the EMA are two electromechanical servo mechanisms different in principle. The clutch is used for achieving repeated switchover between the two servo mechanisms. Modular design is adopted in the EHA, the EMA and the clutch, and the respective functions of the EHA, the EMA and the clutch are independent. The EHA is of a symmetric cylinder structure, and a core part is hollow. The EMA is embedded in the EHA, and system paralleling ofthe two servo mechanisms is achieved. The integral self-lubricating and self-cleaning structure design is adopted in the EMA, lubricating and cleaning of an EMA lead screw, a bearing and other important components are achieved through a closed type hydraulic circulation system, and long-time work reliability of the servo mechanisms is guaranteed.

Description

technical field [0001] The invention relates to an electromechanical servo mechanism, in particular to a high-power integrated heterogeneous redundant electromechanical servo mechanism, which belongs to the technical field of high-power and high-reliability servo. Background technique [0002] With the development of new materials, motor technology, control science and advanced manufacturing technology, the new power by wire (PBW) servo mechanism may completely replace the traditional electro-hydraulic servo mechanism. PBW servo mechanism is mainly divided into electromechanical static There are two types of pressure actuators (Electro-Hydrostatic Actuators, EHA) and electromechanical actuators (Electro-Mechanical Actuators, EMA). [0003] EHA controls the speed and direction of the constant bidirectional pump through the servo motor, and the hydraulic actuator pushes the load to realize the displacement output. It not only has the characteristics of high reliability of ele...
