DEVELOPMENT OF FIRST AND SECOND GENERATION OF ROTARY MODULE WITH AN UNLIMITED DEGREE ROTATION

Abstract

The article deals with the development and changes that have been made to the rotary module with an unlimited degree rotation of first and second generation called URM. The proposed solution of module is suitable for machines and equipment that require unlimited freedom of rotation. URM is based on a modular principle. At first part the article describes design and development of the module prototype, its construction and the principle on which it works. After production of the functional module and detection of shortcomings we started development of the second generation module. The second generation of URM was based on knowledge gained in working on the prototype and its task was to improve the existing module and remove shortcomings of the first generation. Then the article describes adjustments that have been made to produce the second generation module and its goals, which are reduction of clear height of the module and reduction of weight. The main element to achieve these goals was to replace the original angular contact bearings with igus plain bearings.
