Abstract
The pump drive mechanism provides a high reduction drive from a continuous operating motor to a crank arm to oscillate the counterbalanced jack for a pump as used in the oil field. The drive utilizes three series of belts to obtain a reduction of 190 to 1. The belt drive reduces downtime and improves the efficiency of drives for pump jacks.
