Manuellt rotationssystem till väggfixtur

Sammanfattning: This bachelor thesis aims to find a more sustainable and cost-effective solution for a rotation system used for turning walls. The work was carried out by the client Husmuttern AB, which requires a rotation system for rotating wall fixtures in the company's future construction projects in Scandinavia, as well as in Poland and Ukraine. The current fixture is powered by an electric motor, which the company considers to be a costly and less sustainable solution. Therefore, this work will present a more cost-effective and sustainable solution and address the development process for the proposed design. The research question for this thesis is: How can an existing electrically driven rotation system be replaced with a manually operated mechanical rotation system while ensuring that the design meets the internal requirements of Husmuttern AB and the external regulations from the Swedish Work Environment Authority regarding load ergonomics? The work has been done with consideration for cost-effectiveness, ergonomics, and safety. Relevant regulations from the Swedish Work Environment Authority have been reviewed in the course of this work. The work has also focused on developing a concrete proposal where the use of standard components has been prioritized to save resources and result in a cost-effective solution based on available material dimensions from different suppliers. Computer Aided Design (CAD) has been used to draw and assemble components that the rotation system's design consists in a virtual environment. CAD has been used with the help of Solidworks software to give a closer picture of what the construction might look like, as well as how the components sit and their position and direction. The work has been completed within the specified time limit and delivers what was specified in the limitations. The result is a new rotation system - a manually operated mechanical rotation system that enables ergonomic and safe work tasks. The report describes the work process, calculations, drawing documents, and a user description of the rotation system's work tasks, thus constituting the delivery of the work.
