The main function of the direct-coupling main shaft running-in test bench is to carry out a dynamic running-in operation test on the direct-coupling main shaft after replacing the bearing for maintenance, and at the same time monitor the vibration, sound and heat generation of the direct-coupling main shaft during the running process. Moreover, this workbench is suitable for the running-in experiments of direct-coupling main shafts with different model shapes, avoiding the running-in experiment of installing the direct-coupling main shaft on the equipment after maintenance, ensuring the maintenance quality of the main shaft, improving the service life of the main shaft, and reducing the production operation cost.

[0003] In the production process of various parts, since the accuracy of the direct-coupling main shaft of the machining center equipment is directly related to the processing quality, a large number of direct-coupling main shafts are replaced for maintenance every year in the machining center equipment running at full load.
