Embodiment
Following examples are used to illustrate the utility model, but are not limited to the scope of the utility model.
Embodiment one
As shown in figure 1, the utility model provides a kind of parallel axes driver, including housing (not shown), housing Leading screw 1 is inside slidably fitted with, leading screw 1 has thread segment 101 and glissile segment 102, and thread segment 101 is threadedly coupled a nut 2, nut 2 outer surface is installed with first gear 3, and motor 4 is provided with housing, and first gear 3 and the power output shaft of motor 4 pass Dynamic connection;The end of glissile segment 102 connects drag-line steel wire 5, cable sleeve 6 is installed with housing, drag-line steel wire 5 is through drawing Noose pipe 6, the axis of the power output shaft of motor 4 are set with the diameter parallel of leading screw 1, and the diameter parallel of transmission parts is set, Make structure compacter, reduce installing space, small volume, weight is lighter, it is easier to matches power.
Second gear 7 is installed, the number of teeth of second gear 7 is less than the tooth of first gear 3 on the power output shaft of motor 4 Number so that the rotating speed of nut 2 is less than the output speed of motor 4, the movement it is achieved thereby that leading screw 1 slows down, leading screw 1 can be caused to move It is more steady.
Embodiment two
The utility model provides a kind of parallel axes driver, and its structure and embodiment one are essentially identical, and its difference is, On the basis of embodiment one, following improvement has further been done, specifically, in housing has been rotatablely equipped with transition axis 10, transition The 3rd gear 8 and the 4th gear 9 are coaxially installed with axle 10, the 3rd gear 8 engages with second gear 7, the 4th gear 9 with First gear 3 is engaged, and the axis of transition axis 10 is set with the diameter parallel of leading screw 1.The number of teeth of second gear 7 is less than the 3rd gear 8 number of teeth, the number of teeth of the 4th gear 9 are less than the number of teeth of first gear 3, add primary speed-down, reduce further nut 2 Rotating speed so that leading screw 1 moves more steady.
Embodiment three
As shown in figure 1, the utility model provides a kind of parallel axes driver, its structure and embodiment two are essentially identical, Its difference is, on the basis of embodiment one, has further done following improvement, has been provided between thread segment 101 and glissile segment 102 Positive stop lug boss 103, positive stop lug boss 103 are located at the end of thread segment 101.Sensor 11, sensor 11 and limit are installed in housing The position position of boss 103 is corresponding, that is to say, that and the contact of sensor 11 is located on the motion track of positive stop lug boss 103, here, Sensor 11 is often from limit switch or optoelectronic switch etc..
In use, second gear 7 is assemblied on the power output shaft of motor 4, is driven by motor 4 and rotate together, the second tooth Wheel 7 engages with the 3rd gear 8, by transition axis 10, imparts power to the 4th gear 9, the 3rd gear 8 and the 4th gear 9 one Rise and rotate, the 4th gear 9 engages with first gear 3, drives nut 2 to rotate, and nut 2 is meshed with leading screw 1, and nut 2 rotates will Power passes to leading screw 1, and so as to which the rotary motion of nut 2 to be changed into the rectilinear movement of leading screw 1, the rectilinear movement of leading screw 1 pulls Drag-line steel wire 5 moves linearly.As shown in Fig. 2 when motor 4 rotates, nut 2 is driven to rotate by gear drive, so that Leading screw 1 tenses drag-line steel wire 5 away from cable sleeve 6;As shown in figure 3, when motor 4 inverts, leading screw 1 shifts to cable sleeve 6, so as to which drag-line steel wire 5 be unclamped, when positive stop lug boss 103 touches sensor 11, just show the released position of drag-line steel wire 5 Through in place, motor 4 can be to stop operating.
Although above having made detailed description to the utility model with generality explanation and specific embodiment, On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art 's.Therefore, the these modifications or improvements on the basis of without departing from the utility model spirit, belonging to the utility model will Seek the scope of protection.
