1. An apparatus, comprising:
a solid lubricant material having a melting point temperature at which it enters a fluid lubricant state;
a gearbox housing;
a first bevel gear configured to rotate with a first shaft;
a second bevel gear configured to rotate with a second shaft, the second bevel gear positioned to engage with the first bevel gear; and
the solid lubricant material positioned within the first shaft;
wherein the first bevel gear is physically coupled to the solid lubricant material in a manner that allows the transfer of heat energy to the solid lubricant material, and
wherein the solid lubricant material is configured to disperse fluid lubricant to the first bevel gear when motion of the first bevel gear generates sufficient heat energy to raise a temperature of the solid lubricant material above the melting point temperature.
