ABSTRACT:
The oil well pump power unit is provided with a drive for reciprocating the sucker rod of an oil well pump. The rod (18) is fixed to a transverse beam (23) which is integral with ball nut housings (4), one at each end of the beam (23). The ball nuts (2) mounted in the housings (4) engage--in a frictionless, ball bearing type engagement--each a drive ball screw (1). The screws are driven concurrently by a drive motor. The advance in the art is in that this unit has a light weight and requires minimum driving power. Due to its light weight, it can easily be installed without special requirements for the foundation etc. Also, the maintenance is simple as all moving components are entirely enclosed in a housing (26) or protected by bellows (5, 6).
