ABSTRACT

This paper presents a comprehensive study on the optimization of bearing seal interference to improve bearing performance and efficiency. The research investigates various factors affecting seal interference and employs FEA method optimization techniques to find the optimal interference. The results demonstrate the potential benefits of optimized interference in reducing friction, enhancing sealing efficiency, and extending bearing life. In the FEA analysis, there are eight nodded shells of 281 elements were used to find the exact contact area so that interference could be optimized in a way. This analysis carried out by making a three-dimensional model of the assembled bearing with the seal was made by using Creo software and different interference models we chose so that we can have the optimised interference as already said these interference plays a major role in reducing the bearing torque and increases bearing life and this finite element was widely used to determine the contact area contact pressure and many more things like static structural simulation, thermal engineering analysis, model analysis etc, but we have used structural method to determine the contact area and contact pressure so the optimization was carried out. Creo is a good modelling tool which was widely used to make two-dimensional and three-dimensional models. This research we carried out because some customers were facing severe water ingress dusty environments were present and single-sealed bearing failures happened to overcome the situation sealed was carried out but there is a big challenge to optimize the seal interference as it will lead the early failure of the bearing.
