The utility model relates to a decelerator of a small DC motor, particularly to a dynamic declutching device of a decelerator of a small DC motor. The decelerator of a small DC motor comprises a motor, a worm, a worm gear, an output shaft, a box body, an upper cover and a lower cover, wherein the worm gear is freely sheathed on the output shaft and is engaged with the worm; a set of dynamic declutching device is installed on the upper cover; the upper cover and lower cover are designed into a symmetrical shape; the box body is designed into up-down communication. The dynamic declutching device is composed of a declutching plate, a bolt, a return spring, a top pin, a screw, a rotary sleeve and a transverse pin, wherein the declutching plate is provided with the bolt; the top pin is connected with the transverse pin through the screw and an inner hole of the return spring and is fixed on the output shaft; a cam face is installed under the rotary sleeve; the transverse pin is sheathed in a straight groove of the output shaft. The utility model solves the problem of single direction of the existing output shaft. In addition, a set of dynamic declutching device is additionally arranged to change electric operation into manual operation. The utility model solves the problem that the motor can not normally work because of power cut, etc., and devices such as door bodies, etc. can be normally used through manual operation.
Description
Technical field
The utility model relates to a kind of dc micro-motor decelerator, particularly relates to a kind of power-off device of dc micro-motor decelerator.
Background technology
At present, widely used dc micro-motor decelerator on the market, because structural limitations, its output shaft all is that folk prescription is to output, upwards use when installing at left, then need to buy output shaft direct current machine decelerator left, if when on right, needing to install and use, then need to buy in addition output shaft direct current machine decelerator to the right, increased user's expense expenditure.In addition, also can cause the decelerator cisco unity malfunction, use to the user and brought great inconvenience owing to reasons such as power failures.
Summary of the invention
Given this, the purpose of this utility model is to provide a kind of output shaft can change direction, when power down mode, and can be with the original electronic manual dc micro-motor decelerator that is converted into.
In order to achieve the above object, the purpose of this utility model is to be achieved through the following technical solutions: this dc micro-motor decelerator, comprise motor, worm screw, worm gear, output shaft, casing, loam cake, lower cover, wherein worm gear is provided with the worm gear pin hole, and the worm gear sky is enclosed within on the output shaft, and be meshed with worm screw, have straight trough on the output shaft, on cover be equipped with one the cover power-off device, loam cake and lower cover are designed to symmetric shape, cabinet design becomes up/down perforation, and cam surface is arranged at the top of loam cake.
Power-off device is made up of clutch discs, latch, back-moving spring, ejector pin, screw, capstan cover, lateral pin, clutch discs is provided with latch, ejector pin is by the endoporus of screw and back-moving spring, be connected with lateral pin, and be fixed on the output shaft, be arranged to cam surface below the capstan cover, lateral pin is enclosed within the output shaft straight trough.
The utility model is by being designed to symmetry status to loam cake and lower cover, cabinet design becomes up/down perforation, like this when assembling, as long as the position that transposing is somebody's turn to do up and down, just can change the direction that orientation on the casing changes output shaft that is contained in of Worm-gear assembly, solve the single problem of existing output shaft direction.Be exactly to have increased by a cover power-off device in addition, can convert manual operation to, solved owing to reasons such as power failures with electronic, the motor irregular working, and devices such as Men Ti are by manually can use in the same old way.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1 and Figure 2, this dc micro-motor decelerator, comprise motor 1, worm screw 2, worm gear 12, output shaft 14, casing 15, loam cake 6, lower cover 16, wherein worm gear 12 is provided with worm gear pin hole 13, worm gear 12 skies are enclosed within on the output shaft 14, and be meshed with worm screw 2, have straight trough on the output shaft 14, one cover power-off device 3 is installed on the loam cake 6, loam cake 6 is designed to symmetric shape with lower cover 16, casing 15 is designed to up/down perforation, and cam surface is arranged at the top of loam cake 6.Power-off device 3 is made up of clutch discs 4, latch 5, back-moving spring 7, ejector pin 8, screw 9, capstan cover 10, lateral pin 11, clutch discs is provided with latch, ejector pin is by the endoporus of screw and back-moving spring, be connected with lateral pin, and be fixed on the output shaft, be arranged to cam surface below the capstan cover 10, lateral pin is enclosed within output shaft 14 straight troughs.
During work, motor 1 drove worm screw 2 rotations before this, had worm screw 2 to drive me again and took turns 12 rotations, and worm gear 12 by latch 5, clutch discs 4, lateral pin 11, is passed to output shaft 14 with power again.If have a power failure or other reasons, when causing motor 1 not work, can be by overlapping 10 with the moving capstan of hand-screw, because overlapping 10 lower cam faces at capstan contacts with the top cam surface of loam cake 6, form cylindrical cam, so under cam, capstan cover 10 can move up simultaneously, with ejector pin 8 jack-up one segment distance upwards, owing to have straight trough on the output shaft 14, lateral pin 11 is enclosed within the straight trough of output shaft, can move up with ejector pin 8, and latch 5 is extracted worm gear pin hole 13 by clutch discs 4, output shaft 14 just can dally in worm gear 12 holes, at this moment can be by manually working on.When motor 1 energy is working properly, at this moment need manually changing into electronic, again with the moving capstan cover 10 of hand-screw, capstan cover 10 also moves down under the elastic force effect of back-moving spring 7, latch 5 is inserted in the worm gear pin holes 13, and at this moment motor 1 has and can drive worm screw 2 rotations, has worm screw 2 to drive worm gears 12 rotations again, worm gear 12 by latch 5, clutch discs 4, lateral pin 11, is passed to output shaft 14 from new work with power again.
