Abstract: As a forging equipment, the screw press has been widely used in China. However, existing screw presses face issues such as lubrication difficulties, high friction coefficients, low efficiency, and high energy consumption. This paper proposes a more energy-efficient and high-performance planetary roller screw transmission system for the 16MN gear-type electric screw press, replacing the sliding friction in the original screw pair with rolling friction. Based on the basic working principle of the screw press, a standard planetary roller screw pair suitable for this press is designed, and a static finite element analysis of the single thread tooth between the screw and roller side is conducted using ABAQUS. Finally, dynamic simulation of the complete virtual assembly of the planetary roller screw is performed using ADAMS, validating the rationality of the theoretical design. Through theoretical design, static analysis, and dynamic simulation, it is concluded that the structural parameter design of the standard planetary roller screw for the screw press is reasonable and meets the working load requirements of the gear-type electric screw press. This technology transforms the sliding friction of the trapezoidal thread screw pair into the rolling friction of the planetary roller screw, effectively addressing lubrication difficulties, reducing the friction coefficient, significantly improving the efficiency of traditional screw presses, and lowering energy consumption.

摘要： 螺旋压力机作为锻压装备，在我国得到了广泛地应用。然而，现有的螺旋压力机存在 润滑困难，摩擦系数高，效率低，能耗高的问题。文章针对公称力 16MN 的齿轮式电动螺旋 压力机，提出了一种更佳节能高效的行星滚柱丝杠传动的螺旋压力机，将螺旋副原有的滑动 摩擦变为滚动摩擦。根据螺旋压力机的基本工作原理，设计了适用于该压力机的标准式行星 滚柱丝杠副，并使用 ABAQUS 对丝杠与滚柱侧的单个螺纹牙进行静力学有限元分析。最后， 使用 ADAMS 对整体虚拟装配后的行星滚柱丝杠进行动力学仿真分析，验证了理论设计的合 理性。通过理论设计，静力学分析和动力学仿真分析可知，螺旋压力机用标准式行星滚柱丝 杠的结构参数设计合理，能够满足齿轮式电动螺旋压力机的工作载荷需求。该项技术将梯形 螺纹滑动螺旋副的滑动摩擦变为行星滚柱丝杠的滚动摩擦，可以有效解决润滑困难的问题， 降低摩擦系数，显著提高传统螺旋压力机的效率，降低能耗。
