Main Bearing System主轴承系统
From Assembly Model to Engineering Drawings从三维装配到工程图纸
Main Bearing Housing & Interface Development主轴承座结构与接口设计落实
The main bearing arrangement was developed from critical dimensions in the client's legacy drawings and a structural concept established by the project team with reference to similar mill designs.主轴承方案以客户旧图纸的关键尺寸为依据，并结合团队参考类似规格设备确定的结构方案展开。
The project team established the structural concept; I produced the 3D models and engineering drawings for all main bearing components, the assembly model and the procurement preparation list.结构方案由项目团队确定；我完成了全部主轴承零部件的三维模型与工程图纸、装配模型以及采购准备清单。
Drawings and models from company and client projects are processed versions, adapted to protect confidentiality. Academic design materials are my own original work. Conceptual models and simulations are preliminary studies, not validated results.公司与客户项目的图纸和模型均为经过处理的版本，以保护保密信息；学术设计资料为本人原创；概念模型与仿真为初步研究，并非经验证的结果。
View 3D assembly ↓查看三维装配 ↓Retain the bearing centerline datum保留主轴承中心线基准
The bearing-centerline height relative to the baseplate datum must match the client's original design. This retained height coordinates the bearing support position with the mill's rotating centerline.轴承中心至底板基准面的控制高度需与客户原设计保持一致，以协调主轴承支承位置与磨机回转中心线。

The agreed structural and dimensional changes were carried through the component CAD models, assembly relationships and engineering drawings. The retained centerline and baseplate datum guide these connected records.确定的结构和尺寸调整落实到零件模型、装配关系及工程图纸中，各项文件围绕保留的中心线与底板基准组织。
Structural & Interface Development结构方案与接口调整
Bearing support contact arrangement支承接触形式
The team reviewed the contact between the bearing liner and the saddle seat and replaced the original double-curved contact with a dual-arc contact, which makes self-alignment easier during assembly.团队分析了轴承衬与鞍型座的接触形式，将原双曲面接触调整为双圆弧接触方案，便于装配调心。

Lubrication method润滑方式
Revised how and where lubricating oil enters the bearing shell: oil is now fed under high pressure from both sides, so the oil film between the shell and the hollow shaft keeps an adequate thickness and temperature while the mill runs.调整轴瓦润滑油进油方式与位置，采用左右两边进油高压润滑轴瓦的方案，确保磨机运行时轴瓦与中空轴间的油膜厚度与温度足够。
Three-lip sealing arrangement三舌密封结构
A three-lip sealing ring contacts the bearing housing surface and the hollow shaft. I incorporated the related structural and dimensional revisions into the models and drawings.三舌密封环与轴承座表面及中空轴接触，形成相应密封关系。我将相关结构和尺寸调整落实到模型与图纸中。
