Problems solved by technology
[0004] During the working state vibration test of pump products, due to the unstable operation of the transmission part, it leads to equipment failure and product damage is one of the main reasons for the test failure.
In order to solve this problem, the method of hydraulic motor drive and flexible shaft connection is usually adopted at home and abroad, but this method has high requirements for the drive equipment and speed regulating mechanism, and the drive equipment is often greatly affected by the alternating impact of the test piece. Improper installation and commissioning can cause large additional vibrations

The invention discloses a transmission device in a pump product working state vibration test. The device comprises a driving motor (30), a double-diaphragm coupling (1), a transmission shaft (2), a rigid coupling (3), a product mounting base (40) and a test piece (50), and an output shaft arranged on the right side of the driving motor (30) is connected with the left end of the transmission shaft(2) which is transversely distributed through the double-diaphragm coupling (1); and the right end of the transmission shaft (2) transversely penetrates through the rigid coupling (3) and then is connected with an input shaft of a test piece (50) through a product mounting seat (40). According to the transmission device in the pump product working state vibration test, stable and reliable operation of a driving transmission part can be guaranteed in the pump product working state vibration test process, and the transmission device has great production practice significance. The device is largein displacement compensation, controllable in damage position, comprehensive in test piece protection and suitable for various interfaces.
Description
technical field [0001] The invention relates to the technical field of dynamic balance of rotating parts in the vibration test process, in particular to a transmission device in the working state vibration test of pump products. Background technique [0002] At present, pump products are the most commonly used fluid machinery, which are widely used in various pipeline transport fluids to increase the energy of the fluid, overcome flow resistance, and achieve the purpose of transporting along the pipeline. Pumps are used in a wide range of applications, both in agriculture and industry. [0003] Among them, in the research and development project of aero-engine pump products, the vibration test in working state is a very important part. Because the driving motor of the test equipment often does not have the ability of anti-vibration assessment, the driving motor is generally placed outside the vibration table during the test, so the vibration test of pump products in the wor...
