Description

A transmission system for a multi-motor driven servo press with different belts

technical field

Background technique

The reduction ratio required for large and medium-sized servo presses is as high as 30 to 90, or even hundreds. When a single motor is used to drive, a high-power motor has to be selected, resulting in high cost of the press. And because the power of the current servo motor cannot be made very large, its application on large-tonnage servo presses is limited.

However, since the size of the transmission mechanism cannot be made exactly the same, and the synchronization of the motors cannot be completely synchronized, it is easy to cause inconsistent output of multiple motors, and inconsistent actions of multiple sets of transmission mechanisms, making the slider of the servo press In the process of movement, it is easy to deflect and overturn, which will affect the forging precision, and even cause damage to the equipment in serious cases.
