Embodiment Construction
[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] Implement a teaching and demonstration device for measuring the characteristic parameters of belt transmission, including driving wheels and driven wheels arranged horizontally and symmetrically. The passing wheel and the lower passing wheel of the belt form a belt transmission mechanism, and the angle between the belt when the upper passing wheel and the lower passing wheel position of the belt is 120 °. The driving wheel is fixed on the plexiglass box through the shaft and the bearing, and the power is provided by the frequency conversion speed regulation motor connected to the driving pulley shaft at the rear of the box. This motor adopts frequency conversion speed regulation, which can realize stepless speed change. The driven pulley, the upper belt pulley and the lower pulley are respectively fixed on their r...
