Kraftmätning av snäckskruv tiltrotator : Konceptförslag axiell kraftmätning av snäckskruv

Sammanfattning: Rototilt Group AB is a company in Vindeln outside Umeå Sweden, which develops tiltrotators. They are world leaders in their segment and strives to develop even better products. It includes solving the problems that the customers occasionally encounter. If the torque is too high, the gear can break the thread on the screw that drives the gearwheel, resulting in a damaged product. The purpose of this work was to develop a concept for measurement of forces on the screw. When the torque reaches a certain limit, the driver must be notified so that the operation can be interrupted before a breakdown occurs. A status analysis was made and a compilation of different sensors that could be part of a solution was identified. This was further investigated which led to a few concepts which were then assessed based on a few important parameters such as agility, tolerance and accuracy. This resulted in one concept, ranked higher than the others and considered to be the most suitable for further development.
