Gear teeth are deformed due to load. Recently, given the increasingly evolving computer technology, supported by the available literature, we have modern numerical methods at our disposal, such as the finite element method (FEM), which serves as one of the methods for the determination of teeth deformation in the gearing. This paper mainly deals with deformation distribution across the teeth’s face width in relation to the load width of the teeth when meshing occurs. The solution for teeth deformation of spur gears is provided by the FEM.
A trailer for carrying a small boat or water scooters was designed for a private sector company. It was a category O1 non-braked trailer with a gross weight up to 750 kg and a height-adjustable traction device. The frame must be designed and installed in such a way that, during its proposed lifetime, it will withstand all the loads and influences that may occur during construction and operation with an appropriate level of reliability. The designed frame of the trailer is a welded galvanized structure. The article is devoted to the problems related to the stress analysis of a trailer frame.
