Description

Technical Field

[0001] The present invention relates to a belt transmission gear structure that can automatically remove foreign matter and prevent the belt from being punctured and broken, and in particular, to a single row of gear teeth that is designed to be two rows of parallel teeth, and the individual tooth blocks between the two rows of teeth are arranged in a front and rear cross-arrangement. In addition, there is a circle of groove rings in the middle of the two rows of teeth, and there is a hollow groove area between the tooth blocks in each row. Therefore, stones or foreign matter that bounce into the gear structure can be easily and quickly removed from the gear structure of the present invention through the structural features of the groove rings and the hollow groove areas without damaging the belt or causing the belt to break. This is indeed a unique and economically efficient invention. Background Art

[0002] According to the general belt and gear driven structure (please refer to Figure 1 and Figure 2 As shown in the figure, the front gear 1 is composed of a front gear 1, a rear gear 2, a belt 3, two front gear cover plates 4 and two rear gear cover plates 5, and a plurality of screws 6, wherein the front gear 1 has a single row of teeth 101 on its circumference, and a tooth groove area 102 is provided between the teeth 101 and the teeth 101, and a threaded hole 103 is provided at the upper, lower, left and right edges of the front gear 1 close to the teeth 101, and an axial hole 104 is formed at the center of the front gear 1.

[0003] The rear gear 2 has a single row of teeth 201 on its circumference, and a tooth groove area 202 is provided between the teeth 201. A threaded hole 203 is provided at the upper, lower, left and right edges of the teeth 201 of the rear gear 2, and an axial hole 204 is formed at the center of the rear gear 2.

[0004] The belt 3 is a closed belt body, and belt protrusions 301 are distributed in sequence and at equal intervals on the surface of one side thereof.

[0005] The front gear cover plate 4 is a circular plate with a relatively large circular hole 402 in the middle. There are holes 401 at the upper, lower, left, right and outer edge of the circular hole 402 .

[0006] The rear gear cover plate 5 is a circular plate with a relatively large circular hole 502 in the middle. There are holes 501 at the upper, lower, left, right and outer edge of the circular hole 502 .

[0007] During assembly, first, a front gear cover plate 4 is screwed to one side of the front gear 1 by screws (not shown in the figure) through the hole 401 of the front gear cover plate 4 and the screw hole 103 of the front gear 1. Then, a rear gear cover plate 5 is screwed to one side of the rear gear 2 by screws (not shown in the figure). Then, the belt 3 is respectively inserted into the front gear 1 and the rear gear 2, and then another front gear cover plate 4 and another rear gear cover plate 5 are screwed to one side of the front gear 1 and one side of the rear gear 2 by screws (not shown in the figure). Figure 2 shown.

[0008] When using (see Figure 3 and Figure 4A , Figure 4B As shown, since the transmission structure of the belt and gear is installed on the rear tire 13 of the motorcycle 7, so as to drive the rear tire 13 to rotate, and then drive the motorcycle 7 forward, but since the transmission structure of the belt and gear is exposed, when consumers ride the motorcycle, foreign objects or stones 8 often bounce into the belt 3 and the gears. Therefore, no matter whether the foreign objects or stones 8 bounce into the front gear 1 or the rear gear 2, when the gear presses the foreign objects or stones 8 that bounce into and are placed on the belt 3, the foreign objects or stones 8 will cause the belt 3 to be punctured. Then, when the belt 3 is continuously rotated, the belt 3 will gradually produce cracks from the puncture wound, and finally cause the belt 3 to break, causing the motorcycle to lose power, and thus cause a malfunction or danger.

[0009] Therefore, how to prevent the belt from being punctured by foreign objects or stones 8 during transmission, thereby causing the belt to break, is a direction that the industry is eager to improve and design.

[0010] In view of this, the inventor of this case, based on his many years of experience in research and development in related fields, conducted in-depth research on the aforementioned deficiencies and actively sought solutions based on the aforementioned needs. After a long period of hard research and multiple tests, he finally completed the present invention, which solves the common shortcomings and enhances its unprecedented progress and practicality. Summary of the invention

[0011] Therefore, the main purpose of the present invention is to provide a "belt transmission gear structure that can automatically remove foreign matter and prevent the belt from being punctured and broken".

[0012] When the belt and the gear rotate rapidly, foreign objects or stones that bounce into the belt and the gear can be easily and quickly automatically separated from the gear structure of the present invention due to the centrifugal force through the combination of the structural features of the groove ring and the hollow groove area of ​​the gear with two rows of parallel teeth, without damaging the belt or causing the belt to be punctured and broken.
