In the process of servo press operation,ensuring the high accuracy of the slide operation is the core objective of its design and manufacture.Press precision directly affects the quality of stamped parts,precision and mold life.The gear phase synchronization of the transmission mechanism,the core component of a large servo press,is one of the prerequisites and key measures to ensure the accuracy of the slider operation.For this reason,this paper on the large servo press gear synchronization guarantee measures for in-depth analysis and research.
