【摘要】：联轴器是机械传动中一种传递运动和转矩的基本元件,主要用于联接轴与轴(或连接轴等旋转件)。轻型万向联轴器具有传动快、高回转精度、关节轴承承载能力高、轴承寿命长等优点。因此,各类冷轧薄板轧机主传动、型钢轧机主传动中得到广泛的应用。本文以回转直径为?225mm的SWC-225CH轻型万向联轴器为研究对象。对SWC-225CH轻型万向联轴器进行结构分析,利用UG三维软件对其进行精确建模。然后采用Hyper Woks和ANSYS有限元软件对SWC-225CH轻型万向联轴器主要零件进行有限元分析。并对十字轴有限元分析结果与理论计算进行比较。对中间轴的有限元分析之后,提出中间轴需要齿面热处理。然后对联轴器进行模态分析,得出固有频率和临界转速。通过有限元模态分析得出的第一阶临界转速与临界转速理论公式进行比较,两者误差在5%,并且得出SWC-225CH轻型万向联轴器的不会出现共振。最后结合法兰叉头实际断裂情况和有限元分析的结果,提出优化区域,利用OptiStrcut软件对法兰叉头拓扑优化,以OptiStrcut软件优化的结果为理论依据,对现有SWC-225CH轻型万向联轴器叉头参数优化。综上所述,通过对SWC-225CH轻型万向联轴器进行强度分析,模态分析,拓扑优化和参数优化,提高其性能,使其更能够满足工程实际的需求。
[Abstract]:The coupling is a basic component in mechanical transmission to transfer motion and torque. It is mainly used to connect the shaft with the shaft (or the rotating parts such as the connecting shaft). Light universal coupling has the advantages of fast transmission, high precision of rotation, high bearing capacity and long bearing life. Therefore, all kinds of cold rolling mill main drive, profile mill main drive has been widely used. In this paper, SWC-225CH light universal coupling with a rotating diameter of 225mm is taken as the research object. The structure of SWC-225CH light universal coupling is analyzed, and it is modeled accurately by UG software. Then the main parts of SWC-225CH light universal coupling are analyzed by Hyper Woks and ANSYS. The results of the finite element analysis of the cross axis are compared with the theoretical calculation. After the finite element analysis of the intermediate shaft, it is proposed that the intermediate shaft needs tooth surface heat treatment. Then the modal analysis of the coupling is carried out, and the natural frequency and critical speed are obtained. The theoretical formula of the first order critical speed and the critical speed obtained by finite element modal analysis is compared with the theoretical formula of the first order critical speed. The error between them is 5 and it is concluded that the SWC-225CH light universal coupling will not resonate. Finally, combining the actual fracture of flange fork head and the result of finite element analysis, the optimization region is put forward, and the topology of flange fork head is optimized by OptiStrcut software, which is based on the result of OptiStrcut software optimization. Optimization of fork head parameters of existing SWC-225 Ch light universal coupling. To sum up, the strength analysis, modal analysis, topology optimization and parameter optimization of SWC-225CH light universal coupling are carried out to improve its performance and make it more able to meet the needs of engineering practice.
