[0021] The present invention will be further described below in conjunction with the accompanying drawings, see the accompanying drawings.
[0022] A rock mechanics testing machine with continuously changing shear direction. The testing machine consists of a bearing platform 10, a first gear 12, a motor 13, a second gear 20, a bearing 21, a bearing end cover 22, a pillar 23, a shear box, and a Force device composition.
[0023] The bearing platform 10 is in the shape of a three-stage hollow cylindrical boss with varying outer diameters. The upper boss of the bearing platform 10 has threaded holes symmetrically along the orthogonal direction. The middle boss of the bearing platform 10 is provided with a keyway, and the gear pin 19 is placed on the bearing In the keyway of the middle boss of the platform 10, the second gear 20 is installed on the outside of the middle boss of the bearing platform 10 through the gear pin 19, and the bearing 21 is installed on the outside of the lower ...
