Construcción de un módulo didáctico para la ejecución de prácticas sobre engranajes rectos en las asignaturas de diseño mecánico y mecanismos sede Neiva de la Universidad Antonio Nariño

Abstract

The main objective of this work was the design and construction of a teaching module for practice with spur gears. The research design was developed in three phases; each of these phases located in the three specific objectives respectively. A first basic phase that will identify learning results raised in the study plans of mechanisms and mechanical design II on spur gears. A technological surveillance that will improve the identification of at least two didactic modules that handle gears. This select design criteria; one of them that the gears could be disassembled for the accomplishment of several practices; Another criterion was the selected size of the module that allowed it to be manipulated in a practical way, that is, to be able to take it to a classroom. Another criterion was to design the module so that the torque given to the assembly of gears was done manually using a crank or mechanically, with the use of an electric motor. In the design phase, the selected ones were made, choosing nine spur gears with different numbers of teeth, necessary for the elaboration of three practices, which were also implemented in this document. The third phase oriented to construction allows as a final result of this work. As a final conclusion, this module can be used in the topics of kinematics of gears and gear trains within practical exercises of the subjects Mechanical design II and mechanisms
