Problems solved by technology
In this way, the shear resistance of the rubber bearing is tested. The problem with the existing hydraulic compression shear testing machine is that when the vertical force loading cylinder is loaded vertically, the shear plate exerts a horizontal shear force on the rubber bearing. , the rubber bearing will also exert a horizontal force on the lower platen and then on the piston rod of the vertical force loading cylinder, and a large friction force will be generated between the piston of the vertical force loading cylinder and the cylinder body of the vertical force loading cylinder. This friction will affect the accuracy of the vertical loading force output by the vertical loading cylinder, and will also increase the wear between the piston rod and the cylinder, reducing the service life of the vertical loading cylinder
