The invention relates to a maximum bending moment stress measuring device of a circular shaft. The device mainly comprises a working box body, and an air cylinder is mounted at the lower end of the left portion of the working box body and is connected with a long batten; the plane where each long side of the long batten is located is provided with a rack, and the right portions of the racks are meshed with gears respectively; the gears comprise the first gear and the second gear; the first gear and the second gear are coaxially connected with first rotating shafts respectively, the upper half portion and the lower half portion of each rotating shaft are each provided with a through-connection head, and a second rotating shaft is transversely connected between every two through-connection heads which correspond to each other in a front-and-back manner. Each second rotating shaft is axially connected with a third gear and a fourth gear. The upper sides and the lower sides of the two first rotating shafts are each axially provided with a first chain wheel and a second chain wheel. Each first chain wheel and each second chain wheel are sleeved with a first chain and a second chain respectively, and the right ends of first chains and the right ends of the second chains are each sleeved with a chain wheel set. The centers of the chain wheel sets are axially connected with a twisting shaft. The maximum bending moment stress measuring device has the advantages of being simple in structure, low in cost, convenient to use and accurate in measuring.
Description
technical field [0001] The invention relates to a detection device, in particular to a measuring device for the maximum bending moment stress of a circular shaft. Background technique [0002] Generally speaking, when people perform shaft performance testing, the most important thing is to measure the maximum bending moment and bending stress that they can bear. Although there are special instruments for measuring this item, such measuring instruments are often It requires a huge cost and does not meet the needs of economic interests. Therefore, what is urgently needed at present is a low-cost testing device that can quickly check the maximum bending stress that the shaft can withstand. Contents of the invention [0003] In view of the above technical problems, the present invention proposes a circular shaft maximum bending moment stress measuring device with simple structure and low cost. [0004] A measuring device for the maximum bending moment stress of a circular sh...
