Abstract：

The heavy friction screw press is an equipment of low-efficiency and low-performance. However, it can be transformed into a new type of electric screw press by upgrading the power transmission and control systems with all the original major parts, such as original frame, hammerhead, nut and screw. The following two critical technologies for the upgrade of the power transmission system were addressed: (1)To adapt to the large gears spiral motion and swing, and make sure the mutually-meshing gears always have a stable center distance; (2)To minimize the huge impact due to the sudden stop of the high power motor and small gear, when the press strikes.
