Abstract

A powerlock is used to transmit torque between two shafts, to protect important equipment from overloads, and to compensate for the misalignment of assembled shafts. In this study, the effect of the shapes of the inner rings, bolt-fastening force, and friction on power transmission performance of powerlocks is investigated. Finite element analysis and experiments were conducted for two cases, and the analysis results were validated. Analyses were carried out for inner rings of various shapes and for various values of bolt-fastening force and friction coefficient. The main factors that affect the torque transmission performance were investigated based on the analysis results.

파워록은 동력을 전달하는 축에 설치되는 부품으로, 연결되는 두 축의 비정열을 보상하고 과부하 또는 비정상적인 부하가 걸릴 경우 동력을 단절하여 주요 부품을 보호하는 역할을 한다. 본 연구에서는 파워록의 내륜에 형성된 테이퍼 등의 형상과 볼트 체결력, 그리고 마찰이 동력전달 성능에 미치는 영향을 분석하였다. 두 개의 모델에 대해 실험과 유한요소 해석을 수행하여 유한요소해석 결과의 신뢰성을 검증하였고. 유한요소 해석 결과 및 이론 분석을 통해서 각 인자가 동력전달 성능에 미치는 영향을 분석하였다.
