Desenvolvimento de mecanismo de regulagem aplicado ao equipamento “Rosca Scott Máquina"

Abstract

It’s notorious in fitness gyms that the overload caused by the user's inadequate choice of load, or, mainly due to the inadequate user adjustment systems, causes injuries, which can be aggravated by repetition efforts, which end up progressively injuring the affected structures, causing harm to user’s health. This work, had as general objective to develop an improvement that allows adjustments of the force transmission system applied to the Scott Curl Machine, used in bodybuilding gyms, enabling increased user ergonomics, with the development of a variable radius pulley and adjacent mechanical components. Several aspects of a unified PDP methodology were considered, applying the procedures developed in the Pre-Development macro-phase with the creation of the product scope, and in the Development macro-phase, with phase procedures of informational design, conceptual design and detailed design. With the completion of this work, a methodological sequence becomes available, which can serve as a basis for adjustments and dimensioning of similar mechanical systems, applied to the Scott Curl Machine or other equipment and conditions.
