SZWEDOWICZ, Dariusz; BEDOLLA, Jorge; MARTINEZ, Eladio  and  BEDOLLA, Marcos. Discrete Description of Contact Surfaces of Mechanical Joints with Elastic Conical Parts. Inf. tecnol. [online]. 2006, vol.17, n.4, pp.47-52. ISSN 0718-0764.

A discrete description of contact surfaces on elastic conical rings, which couple together the shaft and hub  by frictional forces, is presented. The main objective is to predict regions of potential contact in the mechanical joint, by measurements of the diameter variation along the axial direction. The surface topography is represented by the experimental data. The surface profile is then defined analytically by Bézier curves, instead of the discrete description of the experimental database.  These parameters can be considered to assess the workmanship quality of the conical parts and the quality rating of the conical fit, that effect significantly the reliable coupling of the conical joint in service. Also, the proposed description of discrete surfaces can be used in finite element representation for real contours of the parts.

Keywords : contact surfaces; finite elements; mechanical joint; elastic conical rings; Bézier curves.
