The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 3,4.
A kind of feed screw nut-driven transmission device of screen door for subways, it comprises motor 1, left feed screw nut 3, left-handed screw mandrel 5, screw mandrel shaft coupling 8, dextrorotation screw mandrel 10 and right feed screw nut 12, the output shaft of motor 1 (can adopt dc brushless motor) links to each other with an end of left-handed screw mandrel 5 or dextrorotation screw mandrel 10 by shaft coupling 2, and left-handed screw mandrel 5 links to each other by screw mandrel shaft coupling 8 with dextrorotation screw mandrel 10 and rotates synchronously; The two ends of left-handed screw mandrel 5 are bearing in respectively on left-handed screw mandrel left shaft holder 3 and the left-handed screw mandrel right bearing seat 7, the two ends of dextrorotation screw mandrel 10 are bearing in respectively on dextrorotation screw mandrel left shaft holder 9 and the dextrorotation screw mandrel right bearing seat 13, left side feed screw nut's 3 spinnings are at left-handed screw mandrel 5, move left door 6 and link to each other with left feed screw nut 3 by door suspension element 2-5, right feed screw nut's 12 spinnings are on dextrorotation screw mandrel 10, the door 11 that moves right links to each other with right feed screw nut 12 by a door suspension element 2-5 who also passes through same structure, as shown in Figure 3, left side feed screw nut 3 and right feed screw nut 12 all links to each other with the end of separately anti-rotation crank 2-2, the other end of anti-rotation crank 2-2 all is actively plugged among the gathering sill 2-1, as shown in Figure 4.
Principle of the present invention is: utilize motor to rotate, drives the ball screw rotation of left-handed ball screw and dextrorotation, the screw on the ball screw is received constraint in the rotation of circumferencial direction, will the along continuous straight runs move toward one another, or counter motion.Because door suspension equipment and feed screw nut are linked to be integral body, historical facts or anecdotes shows closing and opening of door suspension equipment.Ball screw has the effect of deceleration simultaneously, so do not need reducing gear.
Details are as follows:
Ball screw of the present invention is made up of one section left-handed screw mandrel and one section dextrorotation screw mandrel, and their two ends all are fixed on the corresponding bearing support.Respectively brushless electric machine, left-handed screw mandrel and dextrorotation screw mandrel are linked to be an integral body with shaft coupling.The feed screw nut lays respectively on left-handed screw mandrel and the dextrorotation screw mandrel, is with a crank on the feed screw nut, and crank is located in the gathering sill of horizontal positioned.Door suspension equipment and feed screw nut are linked to be integral body.When motor just changes,, left-handed screw mandrel and dextrorotation ball screw are just changeed by shaft coupling.And the screw on left-handed screw mandrel and the dextrorotation screw mandrel, because its crank in the gathering sill of level, has limited the circular motion of screw, so screw can only the along continuous straight runs motion.When left-handed screw mandrel was just changeing, its screw moved right; When the dextrorotation screw mandrel was just changeing, its screw was to left movement.And left-hand door suspension equipment, a right door suspension equipment are linked to be integral body with the feed screw nut respectively, so left and right door suspension equipment move toward one another has realized the process of closing the door.
In like manner, the process of opening the door is just opposite with the process of closing the door.During the brushless electric machine counter-rotating,, make the counter-rotating of left-handed screw mandrel and dextrorotation screw mandrel by shaft coupling.And the feed screw nut on left-handed screw mandrel and the dextrorotation screw mandrel, because its crank in the gathering sill of level, has limited feed screw nut's circular motion, so screw can only the along continuous straight runs motion.When left-handed screw mandrel reversed, its screw was to left movement; During the counter-rotating of dextrorotation screw mandrel, its screw moves right.So the relative motion of left and right door suspension equipment has realized the process of opening the door.
Arrange near switch in the fastening position of door suspension equipment and open position, by regulate can the gauge tap door near the position of switch stroke.
In addition, the helical pitch of the helical pitch of left-handed ball screw and dextrorotation screw mandrel can be different, can realize so asymmetrically opening the door or closing the door.
The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
