Features of synchronous belts？

Introduction： This kind of high-toothed arc tooth synchronous belt tooth profile has the following main features compared with the traditional arc tooth synchronous belt tooth profile: (1) The height of the synchronous belt tooth is 14.75% larger than that of the traditional STPD arc tooth, which increases the contact area between the belt tooth and the gear tooth as well as the meshing pressure angle, thus improving the same under the condition of the same unit load bearing strength.

This kind of high tooth arc tooth synchronous belt tooth profile and the traditional arc tooth synchronous belt tooth profile compared with the following main features: (1) synchronous belt tooth profile and the traditional arc tooth synchronous belt tooth profile have the following main features.

(1) synchronous belt tooth height than the traditional STPD arc tooth height is 14.75% larger, increasing the contact area between the belt teeth and gear teeth and meshing pressure angle, thus increasing the synchronous belt load carrying capacity under the condition of the unit load carrying strength remains unchanged.

(2) The height of the teeth of the synchronous belt is 6.06% larger than the height of the gear teeth, to reduce the pressure between the groove of the belt teeth and the top of the gear teeth, improve the wear condition between the teeth of the belt and the stress condition of the bearing layer, and increase the life of the belt.

(3) The four grooves on the top of the teeth of the synchronous belt can remove the air when the belt meshes with the wheel and reduce the noise, and at the same time, the grooves can also deform the top of the teeth and form the elastic top of the teeth, which can reduce the impact of meshing and improve the meshing condition.

Conclusion

(1) Through calculation and simulation, this paper analyzed and compared the design profile of the new high-tooth synchronous belt with the belt wheel tooth profile according to the belt wheel tooth profile (i.e., the belt's calculated tooth profile), and found that one of the matches is very ideal, and the design profile of the belt wheel with the belt tooth profile according to the belt's tooth profile (i.e., the belt wheel's calculated tooth profile) also coincides with the design of the belt wheel tooth profile, which indicates that the new high-tooth synchronous belt with the belt wheel's designed tooth profile is reasonable, and can achieve the close fit during transmission. This shows that the design profile of the new high-tooth synchronous belt and the pulley is reasonable and can achieve a close fit during transmission.

(2) From the drawing of the total reel tooth profile can be seen, the belt mold hob and the belt wheel hob tooth profile of the transition curve do not appear sharp corners, and the eye tooth profile smooth and continuous, the processing process to avoid the phenomenon of ten involved or root cut.

(3) Through the dynamic simulation of the transmission process can be visualized to qualitatively analyze the synchronous belt drive incomplete meshing process of meshing ten.
