Loading method and device for large bearing test

The invention discloses a loading method and device for a large bearing test, and the method comprises the following steps: the middle part of a test shaft driven by a driving device passes through a loading bearing, the two ends of the test shaft are installed in a supporting bearing, and a radial load is applied to the loading bearing through a radial loading frame and a radial loading cylinder; a plurality of axial loading cylinders are distributed on the axial loading seat, the plurality of axial loading cylinders are respectively symmetrical along an X axis and a Y axis in layout, and the output end of each axial loading cylinder respectively applies loading force to the axial loading seat through an axial loading rod. According to the scheme, the loading device and the loading method for the large-scale bearing test are optimized, and the positions of the plurality of axial loading cylinders are reasonably distributed; by adjusting different actions of the plurality of axial loading cylinders, the proce
