减速器箱体的建模与有限元分析 ee （ee） 指导教师：ee 【摘要】减速器是原动机和工作机之间独立的闭式机械传动装置。用来降低原动机转速或增大转矩，以满足工作机的需要。由于减速器具有结构紧凑，传动效率高，传动准确可靠，使用维护方便等优点，故在工矿企业及运输，建筑等部门中运用极为广泛。 减速器箱体作为减速器的主要组成部分之一，要求外形简单，表面平整，便于安装。本设计就是通过减速器箱体的模型建立，以Ansys为分析软件，对减速器箱体进行应力分析，简化箱体的结构。 ANSYS软件是大型通用有限元分析软件， ANSYS的前处理器中有建模功能，但由于直接在 ANSYS 软件中建立减速器箱体模型比较困难，本文是应用Pro/E建模并将其导入有限元分析软件 ANSYS 中，在 ANSYS 前处理器中建立了减速器箱体的三维实体模型。 本文首先对减速器进行了设计并对其箱体部分进行三维实体建模和有限元分析，分析箱体在减速器工作时的应力分布状况。 【关键词】ANSYS 减速器箱体 建模 有限元分析 Reducer box modeling and finite element analysis ee （） Tutor: Abstract: Speed reducer is a independent closed mechanical device to transfer power between primary motors and slave device, which can reduce the speed or increase the torque of the motors to meet the expectations of works. For the outstanding performance of compact conformation, high transmission efficiency, and accurate transmission, speed reducer is widely used in factory and mine well, transportation and construction system etc. Reducer housing as one of the main component of the speed reducer, appearance is simple, smooth, easy to install. This design is through the reduction gear box body model, based on Ansys analysis software, the stress analysis of gear reducer box, simplify the structure of cabinet. ANSYS software is a large general finite element analysis software, ANSYS modeling capabilities of the top processor, but as a result of direct gear reducer box model is established in ANSYS software is more difficult, this paper is the application of Pro/E modeling and import it into the finite element analysis software ANSYS, the reducer casing is established in ANSYS processor before 3 d entity model. This article first gear reducer for the design and the box body parts 3 d entity modeling and finite element analysis, analysis of the case when he worked in reducer stress distribution.
