Problems solved by technology
[0003] At present, there are few experimental instruments for belt transmission. The existing instruments use high-speed belt transmission. The experimental data is automatically collected by the instrument. The experimental process is short. Students can only watch the results displayed in the experiment, and cannot participate in the operation process to experience belt transmission. It is impossible to realize the supplementary explanation of theoretical knowledge, the experimental effect is not ideal, and the existing high-speed rotating experimental equipment has potential safety hazards

The invention discloses a V belt transmission force measuring experimental device. The device comprises a sensor, an experimental table, a displayer which is electrically connected with the sensor through a connecting wire and is fixed on the experimental table, a transmission device fixed on the experimental table, a belt pulley mounted on the output end of the transmission device, and a to-be-measured V belt mounted on the belt pulley, wherein one end of the V belt passes through a loose side force measuring sensor, and the other end of the V belt passes through a tight side force measuring sensor; the ends of the V belt are fixed onto the V belt through adjusting bolts respectively; the loose side force measuring sensor and the tight side force measuring sensor are connected with a small hand wheel through sliding devices; and the input end of the transmission device is connected with a large hand wheel through a connecting rod. According to the device, belt transmission stress condition teaching demonstration can be carried out, the stress conditions in non-working hours and working hours after belt tensioning are understood by measuring the change conditions of force on two sides of belt, and the device is simple in structure and accurate in measurement and can be widely used for teaching experiments and engineering tests.
Description
technical field [0001] The invention relates to a measuring instrument for mechanical design experiment teaching, in particular to an experimental device for measuring the belt force in belt transmission. Background technique [0002] Belt transmission is an important mechanical transmission method, among which V-belt is the most common. The mechanical design and basic courses of mechanical design are the professional core courses of the mechanical engineering major, and the design of belt transmission is one of the important knowledge points of the course. In the teaching process of belt transmission, the force analysis of the belt is the key and difficult point. The understanding of Euler's formula can only be derived from the formula, and the derivation process is abstract and difficult to understand. [0003] At present, there are few experimental instruments for belt transmission. The existing instruments use high-speed belt transmission. The experimental data is autom...
