Study of a torque limiter

by Marcos, Rebal; Bazzi, Ali

Abstract (Summary)
This thesis is carried out on request from Saab Avitronics in Jönköping. Saab Avitronics develops and produces electric actuators that are used to control the wing flaps on flying vessels, both for the civil- and military market. This project aims to study a new type of torque limiter that will be a part of an actuator. The main task of the torque limiter is to disconnect the driving torque if the system goes to an undesirable stop and thereby protect sensitive machine parts from being overloaded.The aim of this thesis was to investigate the parameters that influence on the functionality of the product theoretically and validate these studies with the results from practical experiments. The arrangement of the practical tests was selected in a way that enabled a comparison with the theoretical evaluation.The work has resulted in a good understanding of how the different parameters influence the torque limiter and to what extent these affect the final function. A theoretical relation that describes the significance of different parameters was developed and compared with the results from the practical testing. The theoretical equation was found to be in accordance with the results from the practical tests. Positive changes leading to a more beneficial development of the product have been made based on the knowledge obtained in this study.
