Abstract
Apparatus and methods relate to a gear reducer, which may be used downhole to reduce rotational speed output from a downhole motor, such as a turbine motor, to a slower speed desired for rotation of a drill bit. The gear reducer includes a planetary gear arrangement coupled to receive rotational input from the downhole motor and a cycloidal gear arrangement driven by rotation resulting from the planetary gear arrangement. An output shaft couples to the cycloidal gear arrangement and rotates during operation slower than the rotational input from the downhole motor.
