Description

technical field

[0001] The invention relates to a belt transmission teaching demonstration device, in particular to a teaching demonstration device for measuring characteristic parameters of teaching belt transmission. Background technique

[0002] The belt drive test bench used for teaching at home and abroad is mainly an industrial test bench. This test bench is designed and manufactured by a transmission belt manufacturer, not a classroom teaching demonstrator for belt drive teaching. Domestically, there are mainly DLS-B design belt transmission test benches, etc., which rely on manual operation to adjust the speed load, while the main development direction abroad is computer distributed control type control, which uses digital display panel readings or computer test and analysis software to measure belt slip and transmission efficiency. It realizes the measurement of the slip rate of flat belt and V-belt and the measurement of belt transmission efficiency, and automatica...

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...
