Abstract
The utility model provides a transmission gear used for electric tools having advantages of low costs, high strength, and long service lifetime. The transmission gear comprises a plastic cement wheel disc, plastic cement teeth disposed on the plastic cement wheel disc, a shaft hole disposed in a center of the plastic cement wheel disc, a metal sheet fixedly disposed in the center of the plastic cement wheel disc in a clamped manner. A through hole corresponding to the shaft hole is disposed in a center of the metal sheet, and the periphery of the metal sheet is provided with protruding teeth corresponding to the plastic cement teeth, besides, the periphery of the through hole is provided with clamping holes. The plastic cement wheel disc is provided with a plurality of heat dissipation holes, which are uniformly distributed. Centers of the heat dissipation holes are provided with reinforced ribs. The transmission gear used for electric tools provided in the utility model has advantages of high strength and long service lifetime.
Description
Technical field
The utility model relates to a kind of gear, and especially a kind of electric tool is used driving gear.
Background technique
The plastic cement gear is because its cost of production is low, and technology simply is widely used, still because gear is to be made up of plastics; Its hardness is not high, and the plastics easily fusing of being heated, poor thermal conductivity; And when gear uses, be in contact with one another friction owing between gear, thus heat produced, because the heat transfer of plastics teeth is slow; Thereby teeth gather great amount of heat, and regular meeting causes the teeth distortion, thereby shorten the working life of gear.
The model utility content
The purpose of the utility model is to provide that a kind of cost is low, intensity big, the electric tool of long service life is used driving gear.
The technological scheme that realizes the utility model purpose is following:
Electric tool is used driving gear; Comprise the plastic cement wheel disc, be arranged on the plastic cement teeth on the said plastic cement wheel disc, said plastic roller disk center has axis hole; The intrinsic tinsel of said plastic cement wheel disc therebetween; Be provided with and the corresponding through hole of said axis hole in the middle of the said tinsel, periphery is provided with and the corresponding double wedge of said plastic cement teeth, is provided with hole clipping around the said through hole; Said plastic cement wheel disc is provided with a plurality of equally distributed radiation holes, is provided with stiffening rib in the middle of the said radiation hole.
The beneficial effect of the utility model is following:
The electric tool of the utility model is used driving gear, owing to be provided with a tinsel in plastic cement wheel disc therebetween, and be to have radiation hole on the plastic cement wheel disc and be provided with stiffening rib; Not only help heat radiation, and improved the intensity of wheel disc greatly, the double wedge through tinsel puts in the middle of the plastic cement teeth; Also increased the intensity of plastic cement teeth, and dispelled the heat, reduced the temperature of plastic cement teeth through tinsel; Therefore the driving gear of the utility model has the intensity height, long service life a bit.
Description of drawings
Fig. 1 is the structural representation of the utility model electric tool with driving gear.
Embodiment
The embodiment of the utility model is following:
As shown in Figure 1, the electric tool of the utility model is used driving gear, comprises plastic cement wheel disc 1; Plastic cement teeth 2 on setting and the said plastic cement wheel disc 1; Said plastic cement wheel disc 1 center has axis hole 3, and the intrinsic tinsel 4 of said plastic cement wheel disc 1 therebetween is provided with and said axis hole 3 corresponding through holes 403 in the middle of the said tinsel 4; Periphery is provided with and said plastic cement teeth 2 corresponding double wedges 402, is provided with hole clipping 401 around the said through hole 403; Said plastic cement wheel disc 1 is provided with a plurality of equally distributed radiation holes 101, is provided with stiffening rib 5 in the middle of the said radiation hole 101.
The electric tool of the utility model is used driving gear, owing to be provided with a tinsel 4 in plastic cement wheel disc 1 therebetween, and be to have radiation hole 101 on the plastic cement wheel disc 1 and be provided with stiffening rib 5; Not only help heat radiation; And having improved the intensity of plastic cement wheel disc 1 greatly, the double wedge 402 through tinsel 4 puts in the middle of the plastic cement teeth 2, has also increased the intensity of plastic cement teeth 2; And dispel the heat through tinsel 4; Reduce the temperature of plastic cement teeth 2, so the driving gear of the utility model has the intensity height, the advantage of long service life.
Embodiment recited above describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Design under the spiritual prerequisite not breaking away from the utility model; Various distortion and improvement that the common engineers and technicians in related domain make the utility model technological scheme all should fall in the protection domain that claims of the utility model confirm.
Claims (1)
1. an electric tool is used driving gear; Comprise the plastic cement wheel disc, be arranged on the plastic cement teeth on the said plastic cement wheel disc, said plastic roller disk center has axis hole; It is characterized in that: the intrinsic tinsel of said plastic cement wheel disc therebetween; Be provided with and the corresponding through hole of said axis hole in the middle of the said tinsel, periphery is provided with and the corresponding double wedge of said plastic cement teeth, is provided with hole clipping around the said through hole; Said plastic cement wheel disc is provided with a plurality of equally distributed radiation holes, is provided with stiffening rib in the middle of the said radiation hole.
