Embodiment Construction
[0021] Below in conjunction with accompanying drawing, the present invention is further described, see accompanying drawing.
[0022] A rock mechanics testing machine that continuously changes the shear direction, the testing machine is composed of a 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, 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 is symmetrically provided with threaded holes along the orthogonal direction, and the middle boss of the bearing platform 10 is provided with a keyway. The gear pin 19 is placed on the bearing platform. In the keyway of the middle boss of the platform 10, the second gear 20 is mounted on the outside of the middle boss of the platform 10 through the gear pin 19, and the bearing 21 is installed on the outside of the lower bo...
