摘 要 聚酯反应釜通常为真空操作，其轴密封要求高。作者通过对聚酯反应釜轴密封中轴套零件图和技术要求的分析，对轴套的结构进行改进，有效地降低了成本和加工难度、减轻了结构的重量，同时装拆也较方便。对于薄壁零件内外圆加工中的同轴度问题，设计了专用夹具来夹持工件。车削与磨削间不需经过工装拆解，无重新装夹，所以变形量及误差累积较小，很好地保证了同轴度。本研究旨在为生产实际中批量轴套类零件的结构改进和加工提供有益的参考。

A Study on the Structure of a Polyester Reactor Seal Shaft Sleeve

Abstract Polyester reactors are usually operated under vacuum, and their shaft sealing requirements are high. This article analyzes the part drawings and technical requirements of the shaft sleeve in the shaft seal of the polyester reaction kettle, and improves the structure of the shaft sleeve, which can effectively reduce costs, reduce processing difficulty, and lighten the weight of the structure. At the same time, assembly and disassembly are also more convenient. For the coaxiality issue in the inner and outer circular machining of thin-walled parts, a dedicated fixture was designed to clamp the workpiece. There is no need for tooling disassembly or re-clamping between turning and grinding, so the deformation and error accumulation are small, ensuring good coaxiality. The research aims to provide useful references for the structural improvement and processing of mass-produced shaft sleeve parts in practice.
