Description
Technical field
The present invention relates to a kind of rectilinear motion actuator, specifically a kind of driving, transmission integrated rectilinear motion electromechanical actuator.
Background technology
Existing rectilinear motion actuator major part all is hydraulic pressure or pneumatic actuation, and it is electrically driven (operated) rectilinear motion actuator that small part is only arranged.Existing electrically driven (operated) rectilinear motion actuator is to be assembled by unit modules such as motor, ball-screw and deceleration devices, major defect is that structure is compact inadequately, volume, weight are bigger, because intermediate link is many, will bring adverse influence to the bandwidth and the positioning accuracy of system.
Summary of the invention
The present invention seeks to weak point, a kind of compact conformation, the driving that volume and weight is less, positioning accuracy is high, transmission integrated rectilinear motion electromechanical actuator are provided at existing rectilinear motion electromechanical actuator.
The objective of the invention is to realize by following measure:
A kind of driving, transmission integrated rectilinear motion electromechanical actuator, it comprises motor, leading screw 1 and hollow guide housings 3, one end of hollow guide housings 3 and electric machine casing 4 one ends are connected as a single entity, rotor 6 in the motor is a ducted body, the inner segment of leading screw 1 is threaded onto in the feed screw nut 2 by the screw pair activity, and pass in the ducted body that feed screw nut 2 penetrates rotor 6, and feed screw nut 2 is fixedly connected with the corresponding end face of rotor 6, the outer section of leading screw 1 and on feed screw nut 2 be positioned at hollow guide housings 3, the outer section guide pad 9 of going up an intrinsic diameter greater than leading screw 1 external diameter of leading screw 1, this guide pad 9 or be spline structure, or be flat key structure, correspondingly one section inwall of the corresponding leading screw 1 outer fragment position of hollow guide housings 3 is provided with the keyway that matches with leading screw 1 spline or flat key structure, and they are connected.
Compact conformation of the present invention owing to adopted incorporate design philosophy, has saved some intermediate links, so whole volume, weight reduce greatly.The present invention is not owing to there is gear drive etc. to bring the intermediate link of gap, error etc. easily, so the positioning accuracy height of this actuator makes that also the transmission efficiency of this actuator is higher.And, make that then the dynamic property of this actuator is good, the response fast because rotor of the present invention directly drives the ball-screw nut rotation.
