By adoption of the technical scheme, the safety door reversing driving device has the advantages that (1) the synchronous belt is reversed in a bidirectional mode by utilizing two reversing wheels, synchronous transmission is guaranteed, and the structure is unique; (2) a plurality of mounting plates in the prior art are simplified into one mounting plate, and the safety door reversing driving device is simple and compact in structure; and (3) the safety door reversing driving device is low in machining and mounting cost and convenient to maintain.
Description
Technical field
The utility model relates to a kind of drive unit of realizing the opening and closing of city rail traffic station sliding door.
Background technology
The safety door drive unit is taken to reciprocating cutter synchronously through driving and is realized that sliding door is opened and closure in safety door system.Drive unit is the power source of safety door system, and in the existing safety door system, the form of structure of drive unit is various; Component are more, and structure is comparatively complicated, and perhaps structure is separated into and installs several most of dispersions; There are a lot of weak points in such form of structure: complex structure, and overall dimensions is big, and processing and installation difficulty are big; Cost is high, is not easy to safeguard etc.
Summary of the invention
The purpose of the utility model is to provide a kind of safety door system reverse driven gear of suitable high volume applications; Its maximum characteristics are drive motors, belt wheel and open wheel to be designed to integral structure; Fix by a whole drive unit installing plate; Whole driving device structure compact, low, the first tensile force of cost are little, and transmission efficiency is high.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of safety door reverse driven gear; It comprises that two ends are separately fixed at the arc tooth synchronous belt on the sliding door supporting guide; One end of arc tooth synchronous belt is put switching-over cylinder wheel I on the spot; Switching-over cylinder wheel I is changed the back with the direction that moves along sliding door of arc tooth synchronous belt and is connected circle-arc tooth belt wheel group, and circle-arc tooth belt wheel group is by drive motor drives; Said circle-arc tooth belt wheel group also transmits with switching-over cylinder wheel II and is connected, takes turns II through the switching-over cylinder and converts the direction of arc tooth synchronous belt into move along sliding door direction once more.
Described circle-arc tooth belt wheel group comprises active circle-arc tooth belt wheel that is connected with drive motors and the driven circle-arc tooth belt wheel that is in transmission connection with active circle-arc tooth belt wheel.
Described drive motors is positioned at a side of installing plate; Initiatively circle-arc tooth belt wheel, driven circle-arc tooth belt wheel, switching-over cylinder wheel I and switching-over cylinder wheel II are positioned at the opposite side of installing plate.
At installing plate regulating wheel is set also, regulating wheel is connected with the arc tooth synchronous belt contact of transmission between active circle-arc tooth belt wheel and driven circle-arc tooth belt wheel.
Adopt the utility model of technique scheme, have the following advantages:
(1) utilize two reverse wheels to realize being with synchronously two-way switching-over and assurance Synchronous Transmission, structure is unique;
(2) be reduced to an installing plate to polylith installing plate of the prior art, simple and compact for structure;
(3) processing and installation cost are low, easy to maintenance.
Description of drawings
Fig. 1 is the overall structure of the utility model.
The specific embodiment
As shown in Figure 1; A kind of safety door reverse driven gear; It comprises that two ends are separately fixed at the arc tooth synchronous belt 8 on the sliding door supporting guide; One end of arc tooth synchronous belt 8 is put switching-over cylinder wheel I 4 on the spot, and switching-over cylinder wheel I 4 is changed the back with the direction that moves along sliding door of arc tooth synchronous belt 8 and connected circle-arc tooth belt wheel group, and circle-arc tooth belt wheel group is driven by drive motors 2; Circle-arc tooth belt wheel group also transmits with switching-over cylinder wheel II 3 and is connected, takes turns II 3 through the switching-over cylinder and converts the direction of arc tooth synchronous belt 8 into move along sliding door direction once more.
Above-mentioned circle-arc tooth belt wheel group comprises active circle-arc tooth belt wheel 5 that is connected with drive motors 2 and the driven circle-arc tooth belt wheel 7 that is in transmission connection with active circle-arc tooth belt wheel 5.Wherein, drive motors 2 is positioned at a side of installing plate 1; Initiatively circle-arc tooth belt wheel 5, driven circle-arc tooth belt wheel 7, switching-over cylinder wheel I 4 and switching-over cylinder wheel II 3 are positioned at the opposite side of installing plate 1.And, constant for realizing that arc tooth synchronous belt 8 speed remain a constant speed, at installing plate 1 regulating wheel 6 is set also, regulating wheel 6 is connected with arc tooth synchronous belt 8 contacts of transmission between active circle-arc tooth belt wheel 5 and driven circle-arc tooth belt wheel 7.
The operating principle of the utility model is: utilize two actives, driven circle-arc tooth belt wheel 5,7 and two switching-over cylinders 3,4 through being fixed in the drive installation 1.At first, be connected on the circle-arc tooth belt wheel group through switching-over cylinder wheel I 4; The motor rotation realizes driving driving belt with 5 rotations of driving active circle-arc tooth belt wheel and moves; Accomplish the synchronous pulley switching-over through driven circle-arc tooth belt wheel 7; Guarantee that the speed of band remains unchanged synchronously; Realize the arc tooth synchronous belt motion of switching-over is converted to along the sliding door travel direction through switching-over cylinder wheel II 3 at last, thereby the switching-over of having accomplished safety door system drives function.
