    STUDY THE INFLUENCE OF ROTATION SPEED ON DEFORMATION PROCESS FOR FLEXIBLE COUPLER WITH RUBBER ELASTIC ELEMENT

    Machines. Technologies. Materials., Vol. 11 (2017), Issue 7, pg(s) 336-339

    When operating with flexible couplers with a rubber elastic element according by standard BDS 16420:86, a plastic deformation of the tire is observed after a certain period of time. To investigate the deformation process of the elastic element and to determine the main parameters that affect it, it is necessary to develop a computer model and observe the deformation process when changing the factors of greatest impact. For CAE program in witch is analysing the model is choosing Solid Work Simulation. The results obtained in the study give a clear picture of how the deformations obtained are influenced by the parameters characterizing the operation mode. These results will be used in the design of a elastic element with which the coupler design will operate flawlessly for a longer period of time

    DELTA 3D WIRE PRINTER FOR BUILDING OBJECTS – THEORETICAL PREREQUISITES FOR PROTOTYPE DESIGN

    Industry 4.0, Vol. 2 (2017), Issue 3, pg(s) 127-130

    With the use of 3D printing technology, layer by layer extrusion is possible printing of construction objects, but printers represent a large size and mobility limited metal construction. The main reason for the large size of constructions for existing structures of 3D printers for building objects are large strains of bending moments that construction must take. In a new scheme of 3D printer called "Delta Wired 3D Printer", the large stress created from bending moments are transformed in normal stress from tension. At this time, the printer has been developed as a conceptual project is therefore theoretically necessary to identify efforts in wires which is to be suspended extruders (load). For creating a large scale working 3D printer model is necessary to create a prototype. Through a theoretical study of the basic design parameters can be made a real printer prototype project. By using the theory of similarity can be define a unit of prototype error as to how much it will respond to the real model. This is also the main purpose of this publication.
