Graphical Methods Used to Solve Misalignment Problems of Mechanical Transmissions

This paper presents some graphical methods used to solve different misalignment problems of mechanical transmissions. For this purpose, it was created a mechanical transmission composed of an electric motor with a driving shaft, a coupling and a driven shaft mounted on two pillow block bearings. With the use of two dial indicators, there were measured both parallel and angular misalignment of the constituent elements and follow-up, it was realised a graphic display of the measured values, in order to determine the needed adjustments. Such alignment method has a high level of precision and it does not imply expensive devices. Misalignment of mechanical transmissions represents a broad issue in all factories, and the working personnel is constantly interested in ways to remedy such problems.
