```See if the ViewVertical option (in combination with AxesLabel) helps any.

RevolutionPlot3D[{t, t^2}, {t, 0, 2}, AxesLabel -> {x, y, z},
Ticks -> None, ViewVertical -> {1, 0, 0}]

or

RevolutionPlot3D[{t, t^2}, {t, 0, 2}, AxesLabel -> {z, x, y},
Ticks -> None, ViewVertical -> {1, 0, 0}]

et cetera.
