Abstract:
A rod rotator has a crankshaft with non-aligned crank journals, a first actuating pawl attached to the first crank journal and a second actuating pawl attached to the second crank journal, and a ratchet wheel connected to a polished rod. The first actuating pawl pushes on the ratchet wheel to rotate the ratchet wheel while the second actuating pawl pulls on the ratchet wheel to rotate the ratchet wheel at the same time.
