摘要：针对航空发动机深沟球轴承重复设计率高、定型前需要反复修改参数等问题，以航空发动机深沟球轴承为研究对象，利用计算机高级编程语言VB、CAD及Excel，联合开发了航空发动机深沟球轴承参数化结构设计软件。在航空发动机深沟球轴承的内径、外径及宽度等基本参数确定后，软件在数据库的支持下，确定内部几何参数，最终可实现航空发动机深沟球轴承内圈、外圈、保持架、滚动体及装配的参数化设计和产品图的输出。最后，将该软件与人工设计进行对比，误差在允许范围内。

Abstract：Aiming at the problems of high repetitive design rate of aeroengine deep groove ball bearings and the need to modify parameters repeatedly before finalizing, the parametric structure design software of aeroengine deep groove ball bearings was developed by using VB, CAD and Excel as the research object. After determining the basic parameters such as inner diameter, outer diameter and width of aero-engine deep groove ball bearing, the software determines the internal geometric parameters with the support of database. Finally, the parametric design of inner ring, outer ring, cage, rolling element and assembly of aero-engine deep groove ball bearing and the output of product drawing can be realized. Finally, the software is compared with the manual design, and the error is within the allowable range.
Key words：aeroengine；deep groove ball bearing；parameterization
