Abstract: | |
Roller chain drives are widely used in various high-speed, high-load and power transmission applications, but their complex dynamic behaviour is not well researched. Most studies were only focused on the analysis of the vibration of chain tight span, and in these models, many factors are neglected. In this paper, a mathematical model is developed to calculate the dynamic response of a roller chain drive working at constant or variable speed condition. In the model, the complete chain transmission with two sprockets and the necessary tight and slack spans is used. The effect of the flexibility of input shaft on dynamic response of the chain system is taken into account, as well as the elastic deformation in the chain, the inertial forces, the gravity and the torque on driven shaft. The nonlinear equations of movement are derived from using Lagrange equations and solved numerically. Given the centre distance and the two initial position angles of teeth on driving and driven sprockets corresponding to the first seating roller on each side of the tight span, dynamics of any roller chain drive with two sprockets and two spans can be analysed by the procedure. Finally, a numerical example is given and the validity of the procedure developed is demonstrated by analysing the dynamic behaviour of a typical roller chain drive. The model can well simulate the transverse and longitudinal vibration of the chain spans and the torsional vibration of the sprockets. This study can provide an effective method for the analysis of the dynamic characteristics of all the chain drive systems. Chain Link assembly is extensively used in the industry, the scope of this work is to review the applications in the industry and explore the design considerations that go into the design of the assembly. The work deals into various application aspects and manufacturing aspects to formulate an idea of the system. Finally Finite Element Analysis (FEA) has been used to conduct structural analysis. Since lot of work has already been done in other components, in this work the focus has been narrowed down to specific component of link and its joint. |
