Arc tooth synchronous belt in addition to the tooth profile curve, its structure and trapezoidal toothed synchronous belt are basically the same, with pitch is quite, the tooth height, root thickness and fillet radius were than trapezoid tooth high. With teeth after loading, the stress distribution is good, smooth the tooth root stress concentration, improve the bearing capacity of teeth. Therefore, the synchronous belt of the arc teeth is larger than that of the trapezoid tooth synchronous belt, and can prevent the interference of the tooth in the engagement process.
The arc tooth synchronous belt has good wear resistance, small noise, no lubrication, and can be used in the harsh environment of dust. Has been widely used in food, automobile, textile, pharmaceutical, printing, paper and other industries.
