The hydrodynamic lubrication of the human biobearing gap in the orthogonal curvilinear coordinate jystem is described. The axisymmetrical flow in the biobearing gap between two arbitrary rotational )ithogonal curvilinear surfaces with non-monotonic generating line in the longitudinal direction and changeable height of gap is considered. As a particular case the analytical and numerical characteristics of hree components of the fluid velocity vector in the circumferential, radial and meridional directions for changeable biobearing gap height is presented.
