摘要：

为提高径锻机轴瓦使用稳定性和使用寿命，首先，以SX13径锻机为研究对象，对轴瓦的使用工况进行了详细分析，并明确了锻造力、转速、润滑等参数。然后，借助X射线衍射仪、CETR UMT-3型摩擦试验机对轴瓦的结构进行了详细测试，阐述了巴氏合金、铜合金以及钢背的性能需求。最后，使用熔铸技术借助成分梯度过渡方法设计了具有双金属结构的轴瓦减摩耐磨材料，以改善双金属间的结合强度并延长服役寿命，并通过在双金属材料表面浇注锡基巴氏合金构筑减摩层以进一步提高轴瓦的耐摩擦磨损性能。生产使用表明，该工艺显著提升了径锻机轴瓦的高承载、抗冲击和耐磨损性能，为径锻机轴瓦的高质量生产提供了有效保障。

Abstract: In order to improve the stability and service life of bearing shell for radial forging machine, firstly, for radial forging machine SX13, the working conditions of bearing shell was analyzed in detail, and the parameters such as forging force, rotation speed and lubrication were clarified. Then, with the help of X-ray diffractometer and CETR UMT-3 friction testing machine, the structure of bearing shell was tested in detail, and the performance requirements of Babbitt alloy, copper alloy and steel based were explained. Finally, a friction-reducing and wear-resistant material for bearing shell with a bimetallic structure was designed by using melting and casting technology with the help of component gradient transition method to improve the bonding strength between the bimetallics and extend their service life, and a friction-reducing layer was constructed by pouring Sn-based Babbitt alloy at the surface of bimetallic material to further improve the friction and wear-resistant performance of bearing shell. Production and use show that this process significantly improves the high load-bearing, impact resistance and wear-resistance of bearing shell for radial forging machine, providing an effective guarantee for the high-quality production of bearing shell for radial forging machine.
