Description
Technical field
The invention belongs to industrial valve corollary equipment field, particularly a kind of NEW SERIES OF VALVE ELECTRIC ACTUATORS.
Background technique
Present industrial valve, particularly large-scale industrial valve needs matching used electric device for valve.Adopt conventional driving and control mode at present, conventional electric device for valve is to drive the switch that output shaft is realized valve by motor by endless screw-worm gear, electric device for valve electronic and manually between switching by manually finishing, make troubles to operation.How to use a simple device to realize two-way automatic clutch, be the problem of present technique art, scientific research personnel's research always.
Summary of the invention
The purpose of this invention is to provide a kind of can realize the bidirectional overtaking clutch NEW SERIES OF VALVE ELECTRIC ACTUATORS, a covering device can reach the purpose of bidirectional overtaking clutch.
The objective of the invention is to realize by following technical proposals:
According to NEW SERIES OF VALVE ELECTRIC ACTUATORS of the present invention, comprise motor, be contained in the driving gear on the motor output shaft, mesomerism gear, electronic worm screw with the mesomerism gear engagement, electronic worm gear, the output shaft that connects valve, cylinder block set, it is characterized in that between described electronic worm gear wheel body and output shaft, electronic roller bearing being set, form the bidirectional overtaking clutch mechanism jointly with electronic worm gear wheel body, cylinder block set top is provided with dust-proof cover, for being rotatably connected, the wheel body inner cylinder of described electronic worm gear is made up of 4-8 the arc shaped surface that waits radian between dust-proof cover and the output shaft.This cover worm screw, worm gear, roller bearing are by motoring, so claim electronic worm screw, electronic worm gear, electronic roller bearing.
According to actual needs, can one cover manual worm-manual worm gear-manual roller bearing be set separately at described electronic worm screw-electronic worm gear-electronic roller bearing downside or upside, the termination of manual worm is provided with handwheel, why device of the present invention can realize the bidirectional overtaking clutch, be that the inner cylinder of described worm gear wheel body is made up of 4-8 the arc shaped surface that waits radian owing to adopted special worm wheel body.This cover worm screw, worm gear, roller bearing are driven by handwheel, so claim manual worm, manual worm gear, manual roller bearing.
Match with this electronic worm wheel body, described electronic roller bearing is made up of retainer and rolling element, as a kind of preferential selection, described retainer is made up of with the pole that is connected this end face block plate two end face block plates, columniform rolling element is installed between the both ends of the surface block plate by torsion spring, the number of cylindrical rolling element is corresponding with the number of worm gear wheel body concave profile, and the diameter of cylindrical rolling element equals the 91/100-99/100 of the ultimate range between wheel body arc shaped surface and the output shaft.
Generally speaking, described manual worm gear, electronic worm gear wheel body inner cylinder by etc. 6 arc shaped surfaces of radian formed, the radian of each arc shaped surface is 60 degree.
Connect or the slip ring connection for bearing between described dust-proof cover and the output shaft.
Adopt NEW SERIES OF VALVE ELECTRIC ACTUATORS of the present invention, motor drives is rotated by electronic worm screw, electronic worm screw drives electronic worm gear and rotates, rotation along with worm wheel body, the rolling element that is between worm gear wheel body and the output shaft is done relative movement to a side of wheel body arc shaped surface, from entering the state of contacting with the output shaft state of being separated, worm gear continues motion just can drive the output shaft rotation by rolling element, opens or closes valve.When needing commutation, the motor counter-rotating drives the worm gear counter-rotating, rolling element and output shaft are disengaged and does relative movement to other direction, and the opposite side that arrives arc shaped surface contacts with output shaft, and makes output shaft do reversing motion.Realize the bidirectional overtaking clutch thus.
Manual worm-manual worm gear of the present invention-manual roller bearing component and electronic worm screw-electronic worm gear-electronic roller bearing do not disturb mutually, can distinguish operation separately, need not to switch.
