Dimensionamento de elementos de transmissão aplicados em uma chave de roda múltipla

Abstract

The purpose of this article was design a gear train that may be able to remove and install simultaneously four automotive wheel fasteners, the mechanism results in distributing the same torque to all four fasteners. This gear train is design considering torques required under a tire replacement, and based on AGMA (American Gear Manufacturers Association) standards. To ensure that all fasteners receive the same torque, it had been necessary to use a positive contact clutch, designed to disengage at a pre-set torque. In a second instant, it has been performed the dimensioning of shafts and keys to thereafter select bearings and elastic rings. Finally, a three-dimensional parts modeling at SolidWorks software to set the final dimensions and mass of the product (sic).
