Claims

[Scope of utility model registration request]

A pulley tooth section, which consists of a pulley and a toothed belt, has a cross-sectional shape consisting of an arc at both ends and a straight section at the center;
The toothed belt is composed of an arcuate pulley groove having one center formed between the teeth, and a straight joint connecting the pulley teeth and the pulley groove. The belt teeth have teeth and grooves alternately at a pitch, and the belt tooth base is a part of the arc, and the remaining area is at least two arc areas having equal radii that intersect with each other, and this area and the In a toothed belt drive device composed of a linear joint that connects the roots of the belt teeth, the center point 21.21' of the two circular arcs 18, 18' of the belt teeth is the center point of the circular arc 8 of the pulley groove. 7 toward the belt tooth root side, and both circular arcs of the belt tooth portion 18.
The combined length of 18' is 1 to 3 from the arc 8 length of the pulley groove.
0%, and the angle θ □ formed by the belt tooth joint 17.17' is 15" to 10 degrees larger than the angle θ formed by the pulley tooth joint 11.11'. A driving device for a toothed belt, characterized in that the dimensional relationship of the belt is formed.
