Title   Design and Research of Transmission system of  YS1-125 Closed   Single-point Press                                                           

Abstract：Forging machinery in the social production is widely used in various industrial fields, such as automobile manufacturing, machine tool production, aerospace and so on. The use of mechanical transmission crank press accounted for more than half of the forging machinery, with high efficiency, low energy consumption and cost savings advantages. The design of the press drive system is directly related to the overall layout of the press, work reliability and service life, which restricts the working performance of the press.

The YS1-125 closed single point press is used to complete the design and research of its transmission system. According to the technical parameters of the given press, combined with the industry standard, this paper carried out the transmission system layout, transmission series selection and speed ratio distribution, clutch and brake design and installation, motor selection, flywheel design and selection of body materials. At the same time, the typical parts are designed and verified. Finally, the three-dimensional modeling and  finite element analysis of the transmission mechanism are carried out by using SolidWorks and ANSYS.
