Simple variable speed device

Our factory needs a vertical two-speed agitator in the process of producing paint. If you use a variable speed motor or design a gearbox, it is expensive and has a long manufacturing cycle. To this end, I designed a simple variable speed device. The structure of the simple variable speed device is shown in the figure. It consists of working pulley 1, working shaft 2, pin 3, motor shaft 4 and intermediate shaft 10
