Abstract
The utility model relates to an electric clutch tooth, which comprises a bull gear, a pinion and a compression spring which are respectively arranged on two sides of the bull gear, a gear shaft which penetrates through the centers of the bull gear and the pinion, and a shaft sleeve, wherein one end of the shaft sleeve is provided with a screw cap which adjusts and limits the compression spring. When the electric clutch tooth works, the bull gear is led to rotate through a servomotor, friction force between the bull gear and the pinion is utilized to drive the pinion to synchronously rotate, when the pinion comes across big load, the bull gear and the pinion are separated, the pinion stops rotating, and the bull gear still rotates, thereby protecting the servomotor. The clutch surfaces of the bull gear and the pinion are made into concave-convex surfaces which are mutually engaged, the bull gear and the pinion are guaranteed to overcome friction force, when the bearing load of the pinion is bigger than friction force to be static, and the bull gear normally and stably runs. Screws and the screw cap are arranged on the shaft sleeve, the compression length of the compression spring is adjusted through the screw cap, thereby getting needed friction force. The electric clutch tooth can not generate the phenomenon of big power, small power and uneven power, which has ultra-high reliability.
Description
Technical field
The utility model relates to a kind of electronic clutch tooth, refers to be used for the electronic clutch tooth of vehicle-carrying DVD sliding screen motion or electronic toys especially.
Background technique
The electronic clutch tooth that is used with actuating motor is a kind of transmission device that is of wide application.But this electronic clutch tooth is the clutch built-up gear, and during proper functioning, its large and small gear rotates synchronously by frictional force each other.When small gear is stressed when reaching certain value, large and small gear separates, and small gear does not rotate, and gearwheel is normal rotation under the driving of actuating motor, plays the effect of protection actuating motor.Because load that small gear bears is not a steady state value, the frictional force between the large and small gear is difficult to determine that the size of frictional force is determined by stage clip pressure.Stage clip pressure is mainly made all multifactor impacts such as the material, heat treatment temperature, reduction length of stage clip, and these factors are difficult to control.At present, after in a single day electronic clutch tooth assembled, the length of its stage clip was fixing at this point, and the pressure size is also determined at this point, and is unadjustable.If the pressure of stage clip is little, cause the frictional force between large and small gear little, small gear just separates with gearwheel when bearing very little load, fails to reach the desired design purpose; If the pressure of stage clip is excessive, cause the frictional force between large and small gear to increase, small gear stops operating, and does not also separate with gearwheel when bearing excessive load, causes actuating motor not change, and does not have protective action.In addition, this electronic clutch tooth sends abnormal friction sound once in a while when rotating, rotate also not steady.
The model utility content
The technical problems to be solved in the utility model is the problem that exists at above-mentioned electronic clutch tooth, provides the frictional force between a kind of large and small gear adjustable electronic clutch tooth, and it has high reliability.
The technical solution of the utility model is: electronic clutch tooth, comprise gearwheel, and be located at the small gear and the stage clip of gearwheel both sides respectively, penetrate the gear shaft and the axle sleeve thereof of large and small Gear center, an end of described axle sleeve is provided with regulates spacing nut to stage clip.
Compare with prior art; the beneficial effects of the utility model are: when this electronic clutch tooth is worked; make the gearwheel rotation by actuating motor; utilizing between large and small gear frictional force to drive small gear rotates synchronously; when small gear ran into excessive load, large and small gear separated, and small gear stops operating; and gearwheel is also rotating, thus the protection actuating motor.Gearwheel and small gear clutch surface are made the male and fomale(M﹠F) that cooperatively interacts, and have guaranteed gearwheel and small gear overcome friction, and small gear is when bearing load greater than the frictional force transfixion, the normal smooth operation of gearwheel.Be shaped on screw thread on the axle sleeve and be furnished with nut, obtain required frictional force thereby regulate the stage clip reduction length by nut.Can not produce that power is big, power is little, the uneven phenomenon of power, have high reliability.

Embodiment
As shown in Figure 1, electronic clutch tooth comprises gearwheel 1, is located at the small gear 2 and the stage clip 3 of gearwheel both sides respectively, penetrates the gear shaft 18 and the axle sleeve 4 thereof of large and small Gear center, and an end of described axle sleeve 4 is provided with regulates spacing nut 5 to stage clip 3.
Shown in Fig. 2,3,4, the stage clip 3 that is located between nut 5 and the gearwheel 1 is frustoconic shape, and the one end is located in the gearwheel 1 surperficial annular groove 6.Gearwheel 1 another surface has circular depressed 7, and these circular depressed 7 surfaces are shaped on annular tooth 8.One end of small gear 2 is not toothed pinion stand 9, and the surface of pinion stand 9 also is provided with annular tooth 10, and the another side of small gear 2 is provided with carries out spacing step 12 to the end 11 of axle sleeve.An end 13 of described gear shaft 18 is limited in sleeve end 11, and its other end is provided with jump ring 14.One end of axle sleeve 4 is provided with the outside thread 15 that matches with nut 5 internal threads, comes off for preventing nut 5, also is provided with on the axle sleeve 4 and cap 16.After electronic clutch tooth assembles, be provided with wool felt 17 in the described circular depressed 7, this wool felt 17 can increase friction factor and make frictional force even; Described pinion stand 9 falls in the described circular depressed 7; The nut 5 that screws in makes stage clip 3 be in compressive state, and gearwheel 1 is taken turns under the effect of stage clip 3 with small gear 2 and lumped together.When electronic clutch tooth is worked; make gearwheel 1 rotation by actuating motor; utilizing 1,2 frictional force of large and small gear to drive small gear 2 rotates synchronously; when small gear 2 runs into excessive load; large and small gear 1,2 separates; small gear 1 stops operating, and gearwheel 1 is also rotating, thus the protection actuating motor.Gearwheel 1 is made the male and fomale(M﹠F) that cooperatively interacts with small gear 2 clutch surfaces, has guaranteed gearwheel 1 and small gear 2 overcome frictions, and small gear 2 is when bearing load greater than the frictional force transfixion, gearwheel 1 normal smooth operation.Because when making stage clip, identical reduction length, pressure often are difficult to be consistent, and are shaped on screw thread on the axle sleeve 4 and are furnished with nut 5, obtain required frictional force thereby regulate the stage clip reduction length by nut.Can not produce that power is big, power is little, the uneven phenomenon of power, have high reliability.
In addition, large and small gear is made by the match guiding principle in the utility model, overcomes when rotating and sends abnormal sound because of friction.The utility model is particularly useful for vehicle-carrying DVD sliding screen motion or electronic toys as a kind of hardware fitting.
