First, a simple analysis and research on the current situation of the domestic and international volleyball ball machine, based ona clear principle of serve serve. Followed bya friction wheel tee, for example, targeted to improve the speed of the ball, the rotation characteristics, the belt drive mechanism to replace the friction wheel device, making volleyball in force issued before the ball longer, exercise more stable. Finally, the mechanical structure of the belt drive, the focus is to the volleyball serve the process, that is, into the conveyor belt to the speed and force analysis of the movement of the ball this process. Finally, summed up the difference with the Transmission tee and the original friction wheel serve to further perfect tee device improvement program.
