ABSTRACT:
A power transmitting device for an oil well pump of the type which utilizes a rotating power source and provides an input capable of operating a pair of cranks for driving a reciprocating pump. The power transmitting device includes a first speed reducer having an input shaft with a pinion bevel gear mounted thereon with the input shaft being operably connected to the power source. The first speed reducer also includes a ring bevel gear in meshing engagement with the pinion bevel gear which is fixedly mounted on a intermediate location of a rotatable output shaft. The output shaft operates a second speed reducer at each end thereon which is capable of providing an output which can be directly coupled to the cranks. The invention includes a method of manufacturing utilizing a number of existing components.
