Abstract
The utility model relates to an anti-reversion braking device in intermittent movement. The anti-reversion braking device comprises a substrate and a motor fixed on the substrate, wherein the motor is connected with a shaft; an inner star wheel is connected on the shaft; an outer sleeve is arranged outside the inner star wheel; a group of inner star wheel grooves are arranged on the outer wall of the inner star wheel; wedge blocks which are parallel to the shaft are arranged inside the inner star wheel grooves; springs are fixed on the inner walls of the inner star wheel grooves; rollers connected with the other ends of the spring; and the rollers are arranged between the wedge blocks and the inner wall of the outer sleeve. The anti-reversion braking device has simple structure and can effectively prevent a mechanism from reversely rotating when the mechanism stops; and after the anti-reversion braking device is used for long term, the function of the anti-reversion braking device is not affected, and the service life is long, thereby the wide application of the anti-reversion braking device is facilitated.
Description
Technical field
The utility model relates to braking device anti-reverse in a kind of intermittent movement.
Background technique
When axle stopped, owing to stop the reverse inertia (inertia that rotates counterclockwise) to be brought when receiving intermittent movement moment, this reverse inertia drove an axle reverse rotation, has influenced the transmission of mechanism.The present device that reverses that prevents adopts the brake holding break, and the brake holding break must be in braking state for a long time, thus the load when increasing work, and braking effect is bad, and working life is short.
Summary of the invention
The utility model will solve the shortcoming of above-mentioned existing technology, and braking device anti-reverse in a kind of intermittent movement is provided, and can effectively prevent reversing when locking mechanism stops.
The utility model solves the technological scheme that its technical problem adopts: anti-reverse braking device in this motor intermittent movement; Comprise pedestal, be fixed on the motor on the pedestal, motor is connected with axle, is connected with star-wheel on the axle; Star-wheel is provided with overcoat outward; On the star-wheel outer wall, have one group of star-wheel groove, in the star-wheel groove, be provided with the voussoir with the parallel installation of axle, and on the inwall of star-wheel groove, be fixed with spring; The other end of spring is connected with roller, and this roller is between the inwall of voussoir and overcoat.Motor driving shaft rotates, when axle rotates for clockwise direction, roller receive friction and spring force be brought to wedge groove spaciousness locate, not by wedging in wedge groove, so star-wheel can not drive the overcoat rotation.When axle stops the back when counter-rotating takes place, roller receive the friction effect overcome spring force by wedging in wedge groove, drive overcoat and rotate together because overcoat is positioned on the pedestal, thereby play the effect of counter-rotating braking.
The effect that the utility model is useful is: the utility model is simple in structure, can effectively prevent reversing when locking mechanism stops, and not influence the function of braking device after long-term the use, and long service life helps extensive popularization.

Fig. 1 is for being equipped with the structural representation of brake holding break on the existing technology axis;
Fig. 2 is the plan view of the utility model;
Fig. 3 is the right elevation of the utility model.
Description of reference numerals: pedestal 1, motor 2, axle 3, star-wheel 4, star-wheel groove 4-1, overcoat 5, voussoir 6, spring 7, roller 8.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing: anti-reverse braking device in this motor intermittent movement; Comprise pedestal 1, be fixed on the motor 2 on the pedestal 1, motor 2 is connected with axle 3, is connected with star-wheel 4 on the axle 3; The star-wheel 4 outer overcoats 5 that are provided with; On star-wheel 4 outer walls, have one group of star-wheel groove 4-1, in star-wheel groove 4-1, be provided with the voussoir 6 with axle 3 parallel installations, and on the inwall of star-wheel groove 4-1, be fixed with spring 7; The other end of spring 7 is connected with roller 8, and this roller 8 is between the inwall of voussoir 6 and overcoat 5.Motor 2 live axles 3 rotate, when axle 3 rotates for clockwise direction, roller 8 receive friction and spring force be brought to wedge groove spaciousness locate, not by wedging in wedge groove, so star-wheel 4 can not drive overcoat 5 rotations.When axle 3 stops, reversing, roller 8 receive the friction effect overcome spring force by wedging in wedge groove, drive overcoat 5 and rotate together because overcoat 5 is positioned on the pedestal 1, thereby play the effect that counter-rotating is braked.
The utility model is simple in structure, can effectively prevent reversing when locking mechanism stops, and not influence the function of braking device after long-term the use, and long service life helps extensive popularization.
Though the utility model is through illustrating and describe with reference to preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
