Abstract
The utility model relates to a grooved wheel dividing mechanism which changes subsequent rotation to intermittent rotation, and comprises a motor, a worm, a double-gear, an output gear, a grooved wheel and an output shaft, wherein the worm is assembled on the output shaft of the motor, the worm is externally meshed with gears under the phase of the double-gear, the double-gear is externally meshed with the output shaft, the outer side of the upper end surface of the output gear is provided with a round pin, the outer side of the grooved wheel is provided with a plurality of wheeled grooves which are meshed with the round pin, and the grooved wheel is driven to rotate by the output wheel, and is installed on the output shaft. The grooved wheel dividing mechanism drives the worm and the double-gear to rotate through the motor, conveniently transforms rotation power of the motor into power of intermittent motion in a certain time through the round pin on the output gear and the dividing wheeled groove of the grooved wheel, and application devices can be directly installed on the output shaft of the grooved wheel in application.
Description
Technical field
The utility model relates to a kind of mechanical transmission mechanism technical field, refers in particular to a kind of continuous rotation here and converts the Geneva index mechanism that rotates from intermittently to.
Background technique
In mechanical transmission, motor generally can only provide certain speed and rotating power moment of torsion, in concrete the application, transfer rate and moment of torsion according to the output shaft needs, we select us to need the power or the model of motor, realize transfer rate and the moment of torsion that output shaft needs by certain drive transmission device then, if but we need a kind of displacement at intermittence rotational power, general mechanical transmission structure just to be difficult to accomplish, for example: a kind of automatic projection machine toy, we are printed on picture and text on the film, when needs are watched, need film rotation certain distance, watch then, after crossing certain hour, need watch down the picture and text of one page automatically.This just needs the power of certain hour displacement intermittently.Common design can intermittently be rotated by the control motor of single-chip microcomputer, realize that we need a kind of displacement at intermittence rotational power, but this design cost is higher, and also more complicated of structure.
The model utility content
The utility model will provide a kind of will the rotation continuously by simple mechanical transmission structure to convert the Geneva index mechanism that rotates from intermittently in view of the shortcoming of said apparatus.
The Geneva index mechanism that the utility model provides, it comprises motor, worm screw, duplicate gear, output gear, sheave, output shaft, worm screw is assemblied on the output shaft of motor, worm screw and duplicate gear lower gear outer gearing mutually, duplicate gear and output wheel outer gearing, the outside, upper-end surface at output gear is provided with round pin, the sheave outside is provided with the race that some is meshed with round pin, and sheave is by the output wheel driven rotary, and sheave is installed in output shaft.
Described sheave outer circumference equidistantly is provided with 12 races.
Described output shaft end is provided with film box, and film box is provided with film slewing gear, and the film drives the film by output shaft and rotates on slewing gear.
The utility model beneficial effect is: this Geneva index mechanism, drive worm screw and duplicate gear by motor rotate, calibration race by round pin on the output gear and sheave, easily revolution power is changed into the power of certain hour intermittent movement, during application, at the output shaft of sheave application apparatus is installed directly and is got final product.
Description of drawings:
Fig. 1: be the utility model embodiment's three-dimensional structure diagram
Fig. 2: be the utility model embodiment's exploded view
Embodiment:
Only be the utility model preferred embodiment below, do not limit protection domain of the present utility model with this.
See shown in Fig. 1-2, a kind of Geneva index mechanism that the utility model provides, it comprises motor 1, worm screw 2, duplicate gear 3, output gear 4, sheave 5, output shaft 6, worm screw 2 is assemblied on the output shaft of motor 1, worm screw 2 and duplicate gear 3 lower gear outer gearing mutually, duplicate gear 3 cogs and output wheel 4 outer gearings, is provided with round pin in the outside, upper-end surface of output gear 4, and sheave 5 outsides are provided with the race that some is meshed with round pin, sheave 5 is by output wheel 4 driven rotary, and sheave 5 is installed in output shaft 6.
We are provided with the race number of sheave 5 outer circumference according to the displacement distance needs of using.For example with this structure applications in automatic projection machine toy, we are provided with film box 7 in output shaft 6 ends, film box 7 is provided with film slewing gear, and the film 8 on film slewing gear, is driven the films 8 by output shaft 6 and rotates.Equidistantly be provided with 12 races in sheave 5 outer circumference.
When motor 1 is just changeing, to duplicate gear 3, reach output gear 4 again, utilize the contacting of 12 groove positions of circumferencial direction 12 five equilibriums on round pin and the sheave 5 on the output gear 4, make that sheave 5 is each to rotate 30 ° by being assemblied at 2 transmitting movements of the worm screw on the motor drive shaft; The output shaft 6 that cooperates with sheave 5 drives film box 7 each corresponding displacement distances, thereby makes the film 8 accurately move an image.Otherwise, when motor 1 counter-rotating, accordingly by sheave 5 and with it the output shaft 6 of coaxial cooperation drive film boxes 7 each corresponding opposite directions and move a certain distance displacement (picture displacement), thereby make the film 8 move a certain distance displacement exactly in the other direction.
This Geneva index mechanism, drive worm screw 2 and duplicate gear 3 by motor 1 rotate, calibration race by round pin on the output gear 4 and sheave 5, easily revolution power is changed into the power of certain hour intermittent movement, during application, at the output shaft 6 of sheave 5 application apparatus is installed directly and is got final product.Be provided with film box 7 as our output shaft 6 ends, film box 7 is provided with film slewing gear, drives the film 8 by output shaft 6, can realize the automatic rotation of the film 8, so that we watch.
