Abstract
The utility model discloses a worm wheel for a rolling curtain, comprising a gear wheel. The warm wheel for a rolling curtain is characterized in that the center of the gear wheel is provided with an axle hole; the upper and the lower surfaces of the axle hole are plane surfaces; the outer ring of the gear wheel is provided with wheel teeth; two sides of the tooth surface of the wheel teeth form an inclined angles of 45 degrees; and the end surface of the gear wheel is provided with a round groove. The worm wheel for the rolling curtain is low in coefficient of elastic deformation, good in smoothness of operation and small in making and installation errors, thereby being capable of increasing the working precision of the matching component of the rolling curtain and prolonging the service life.
Description
Technical field
The utility model belongs to a kind of gear, specifically is a kind of roller shutter worm gear.
Background technique
The composition structure of gear generally has the gear teeth, teeth groove, end face, normal plane, top circle, root circle, basic circle, standard pitch circle.Employed in current roller shutter production process have a helical gear, worm gear just, though various roller shutter fit methods are variant, but problems such as having all basically that the gear resiliently deformable is big, gear teeth angle is unreasonable, install and make trouble, cause the balance of gear operation relatively poor, quality of fit with other parts in the using process is not high, influences the working life of parts.
The model utility content
The purpose of this utility model provides a kind of roller shutter worm gear, and it is low to reduce the gear elastic deformation coefficient, improves the homework precision of roller shutter component, increases the service life.
The technical solution of the utility model is as follows:
A kind of roller shutter worm gear includes gear, it is characterized in that described Gear center has axis hole, and the axis hole top and bottom are the plane, and there are the gear teeth gear outer ring, and gear teeth flank of tooth both sides are 45 degree oblique angles, and circular groove is arranged on the gear face.
The utility model is taken turns the flank of tooth and is set to 45 degree oblique angles, can strengthen the balance of gear operation, and comparatively convenient when making and installing, and error is also less; Simultaneously gear face is provided with circular groove, the pressure when having cushioned the gear operation, and therefore the elastic deformation coefficient who has reduced gear can improve the homework precision of roller shutter component, increases the service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of roller shutter worm gear includes gear 1, it is characterized in that there is axis hole 2 at described gear 1 center, and axis hole 2 top and bottom are the plane, and there are the gear teeth 3 gear 1 outer ring, and the gear teeth 3 flank of tooth both sides are 45 degree oblique angles, on gear 1 end face circular groove 4 are arranged.
