As primary election scheme, the first groove is opened in the upper surface of described Timing Belt body, the rectangular shape of its cross section.It is convenient that upper surface offers Pocket Machining, and the arranging of rectangular-shaped groove is conveniently cut edge of a knife when cutting and entered groove.

Alternatively, the first groove is opened in the lower surface of Timing Belt body, the rectangular shape of the first groove cross section.Timing Belt curves inwardly after cutting and cutting, plug into circlewise, if the first groove is opened in Timing Belt body upper surface, then the first groove can be subject to the tensile force of the generation owing to bending, tensile force is excessive may cause tearing of synchronous belt body, if the first groove is arranged on the lower surface of Timing Belt body, can avoid the appearance of above-mentioned situation completely.

As a scheme again, the first groove is opened in the upper surface of Timing Belt body, and the first groove cross section is inverted triangle shape.First groove of inverted triangle shape compares the first rectangular-shaped groove, is more conducive to cutter and carries out accurately locating and accurately cutting cutting, improve tooth matching degree further.

It is worth mentioning that, Timing Belt body and described Timing Belt tooth one-body molded.Ensure that band tooth difficult drop-off, improve the bending resistance of Timing Belt main body, anti-pressure ability.

In addition, static line surface surrounding is equidistantly provided with multiple groove.Static line is not fixed length, and the equidistant setting of multiple groove, can directly measure, and cuts cut static line depending on concrete condition.

Compared with prior art, the utility model has the advantage of: by the optimal design to Timing Belt, set up the first groove, decrease the error of cutting and occurring when cutting Timing Belt, improve validity, avoid occurring opening not match condition, reduce the wasting of resources, the reasonable setting of static line simultaneously further increases the firm degree of Timing Belt.
