a. Number of meshing teeth The number of meshing teeth between the patterned conveyor belt and the small pulley should be ≥6. Circumstances. b. The width, pitch and pitch length of the pattern conveyor belt. Due to the determination of the width of the timing belt, the calculation formula is complicated. Therefore, in the actual design, the circumferential force is often used to calculate, and then refer to the allowable circumferential force in the relevant mechanical design manual. The corresponding bandwidth and pitch are generally 5.08. After determining the pitch and bandwidth, calculate the length of the pitch line according to the initial center distance, and then select according to the standard. If it does not meet, the center distance can be adjusted. c. The tooth shape of the timing belt drive mechanism of the computer flat knitting machine generally uses a circular arc shape, and some selects a trapezoid shape, but no matter what kind of tooth shape, it is necessary to satisfy that a circle on the pulley is tangent to the pitch line of the belt, and implement Pure rolling, the second is that the distance between the corresponding points of two adjacent teeth on the pulley on this arc is equal to the pitch of the timing belt. In order to ensure good performance when the belt is engaged with the pulley, the tooth profile angle of the pulley should be correctly selected during the design.According to the test of Japan's Yamato Fufu and our factory during the actual trial production, when the tooth profile angle is 20 When the temperature is between 25 ° and 25 °, the interference between the gear tooth and the belt tooth is small, and the deviation of the tooth profile angle is about ± 1 °.
