The figure shows the universal material testing machine selected for experimental research. The maximum test load of the helical gear double split precision forging testing machine is 300KN. For example, the table shows the basic technical parameters of the universal material testing machine. The equipment has the functions of superposition, analysis, processing, storage, printing, drawing curve and so on.
The power transmitted by the servo motor drives the beam to move up and down to realize the loading process of helical gear double split precision forging test. It has accurate loading speed and force measuring range, and has higher accuracy and sensitivity for the measurement and control of load, deformation and displacement. It can also carry out the automatic control test of constant speed loading, constant speed deformation and constant speed displacement.
