Introducing the new belt drive - Elastic engagement and friction coupling with the transmission structure, transmission principle. On the PX-I belt drive test machine, the dynamic performance of the new belt drive was studied and compared with the O-shaped V belt. The results show that the transmission efficiency of the new belt transmission is higher than that of the O-type common V belt, and the transmission efficiency of the new belt is stable at 91% -95% when the effective tension is 49N-98N. When the pre-tension reaches more than 22.07N, The sliding coefficient of the new belt drive is stable at 1% ~ 2% when the tensile force is in the range of 0 ~ 10 7.0 8N. When the preload is small (5.88N), the effective pulling force of the new belt drive reaches about 98N. When the critical pretightening force is reached, the new type of belt drive reaches the maximum effective pulling force and maintains a relatively stable value. The maximum effective pulling force of the new type belt drive is obviously greater than the maximum effective pulling force of the O-type ordinary V belt. The experimental and theoretical findings are consistent.
