摘要

针对某高空救援车行星减速器薄壁齿圈径向尺寸大、承载载荷大和精度高等要求，分析了薄壁齿圈在加工和热处理过程中的变形问题，找到了工件变形问题的原因，制定了解决方案，优化了薄壁齿圈加工和热处理的工艺路线；使用Deform热处理仿真软件，模拟了优化后的热处理路线，验证了优化方案的可行性。该优化方案提高了工件的精度，符合某高空救援车行星减速器在复杂工况条件下正常工作的要求，确保了机械设备的安全平稳运行。工程实践表明，该优化方案适用于低速重载的高空救援车回转机构减速器，具有较高的经济实用性。

Abstract

Aiming at the requirements of large radial size， large load-bearing load and high precision of the thin-walled gear ring of a planetary reducer for a high-altitude rescue vehicle， the deformation of the thin-walled gear ring during processing and heat treatment is analyzed， and the cause of the deformation of the workpiece is found. A solution is developed， the process route of thin-walled ring gear processing and heat treatment is optimized. By using Deform heat treatment simulation software， the optimized heat treatment route is simulated， and the feasibility of the optimized scheme is verified. This optimization scheme improves the accuracy of the workpiece， meets the requirements of a certain high-altitude rescue vehicle planetary reducer to work normally under complex working conditions， and ensures the safe and stable operation of mechanical equipment. Engineering practice shows that this optimization scheme is suitable for low-speed and heavy-duty high-altitude rescue vehicle slewing mechanism reducer， and has high economic and practicality.
