FIELD: machine building.
SUBSTANCE: invention relates to electric drilling equipment, namely to gearboxes for transfer of rotation from electric motor to bit. Reduction gear of downhole motor has housing, drive shaft, which gear rims of which with right and left directions of inclination of teeth form rows of engagement with satellites and crown wheels, having right and left directions of inclination of teeth, carrier and spacer sleeves. Crown wheels and remote bushings are equipped with lengthwise projections facing the surface housing and are fixed to each other by means of pins mounted in projections. On the outside on the longitudinal protrusions there are slots forming a solid channel, in which current-conducting strands are laid.
EFFECT: broader functional capabilities of the reduction gear for use in the electric drill due to the conductive conductors in it.
